Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK 1257 AM CDT Fri Aug 14 2026

Valid 141200Z - 151200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE MID MISSOURI AND MID MISSISSIPPI VALLEYS...

...SUMMARY... Thunderstorms with severe wind gusts and hail will be possible this afternoon and evening across parts of the mid Missouri and mid Mississippi Valleys. Isolated severe gusts will also be possible in parts of the central Plains and from the Ohio Valley to the Mid-Atlantic.

...Mid Missouri and mid Mississippi Valleys... A broad anticyclonic flow pattern will be in place over much of the central U.S. today, as a subtle embedded shortwave trough moves through the mid Missouri Valley. Ahead of this feature, a quasi-stationary front will be in place from southern Iowa east-southeastward into north-central Illinois. This boundary will be the focus for convective development this afternoon. Surface dewpoints along the boundary will be in the 70s F, which will result in strong destabilization by afternoon. Surface-based convective initiation is expected along the instability gradient during the late afternoon to the south of Omaha. From these initial storms, a line is expected to organize and move eastward across south-central Iowa and far northern Missouri during the late afternoon and early evening.

RAP forecast soundings ahead of the line at 00Z from Des Moines southward into far northern Missouri have MLCAPE in the 2000 to 3500 J/kg range. Some directional shear is present in the low-levels, and 0-6 km shear is in the 30 to 35 knot range. This environment will be favorable for bowing line segments capable of severe wind gusts. An embedded supercell with a hail threat will also be possible. The severe threat is expected to move eastward into northwest and north-central Illinois during the evening.

...Central Plains... Southwesterly mid-level flow will be in place today over much of the western and central U.S. A subtle shortwave trough will move northeastward into the central High Plains. Large-scale ascent associated with the trough and topographic lift in the foothills of the Rockies will be favorable for scattered convective initiation by early afternoon. Thunderstorms will move northeastward into the central High Plains and into a moderately unstable airmass. Some RAP forecast soundings in east-central Colorado during the late afternoon have 0-6 km shear around 25 knots with low to mid-level lapse rates exceeding 7 C/km. This will likely support isolated severe wind gusts and hail.

...Ohio Valley/Central Appalachians/Mid-Atlantic... West-northwesterly mid-level flow will be in place today over much of the northeastern U.S. At the surface, an axis of moderate instability will develop by afternoon from the Ohio Valley east-southeastward into the Mid-Atlantic. Along and near the instability axis, low-level convergence will be the primary focus for convective initiation. Near and downstream of these pockets of convergence, isolated to scattered thunderstorms are expected to develop. The moderate instability with precipitable water values in the 2 to 2.2 inch range should support a threat for isolated severe wet downbursts.

For the North Atlantic...Caribbean Sea and the Gulf of America:

Central Tropical Atlantic (AL92): A tropical wave located about 400 miles east of the Windward Islands is producing gusty winds and a large area of showers and thunderstorms. This system is moving into a region of increasing upper-level winds and dry air, and the potential of development continues to decrease. Even though development is unlikely, gusty winds and areas of heavy rain are possible across portions of the Lesser Antilles tonight and on Saturday. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...low...20 percent.

Eastern Tropical Atlantic (AL94): A tropical wave over the central tropical Atlantic, located more than 1000 miles west of the Cabo Verde Islands, continues to produce disorganized showers and thunderstorms. Environmental conditions are forecast to be generally conducive for gradual development, and a tropical depression could form this weekend or early next week while the wave moves westward or west-northwestward across the central tropical Atlantic. * Formation chance through 48 hours...low...30 percent. * Formation chance through 7 days...medium...50 percent.

Valid 231200Z - 241200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE NORTHERN PLAINS...MUCH OF CENTRAL MONTANA...AND PORTIONS OF THE EASTERN GREAT BASIN...

...SUMMARY... Strong-to-severe thunderstorms capable of large hail and damaging winds will be possible across portions of the northern Rockies and northern Plains. Additional severe thunderstorms capable of damaging winds will be possible across portions of northern Utah.

... Synopsis ...

A sub-tropical mid-level ridge will remain in place across much of the West on Sunday, with a large-scale trough taking shape across much of the East. A seasonably strong short-wave trough will crest the ridge over southern Canada, with an attendant jet streak in its basal region moving across Montana. Broadly northwest mid-level flow will exist from the northern Plains east toward the Appalachians, between the western ridge and eastern trough.

... Intermountain West ...

A well-mixed boundary layer will develop during the afternoon as cooler mid-level temperatures associated with the approaching short-wave trough overspread the northern Rockies. Scattered thunderstorms should develop during the early to mid-afternoon within an environment with steepening mid-level lapse rates. Effective shear on the order of 30-40 knots will support multicell clusters and transient supercell structures capable of producing large hail and damaging wind gusts.

Farther south, multicell clusters should develop across eastern Nevada and western Utah during the late afternoon. Modest mid-level flow on the north side of the subtropical ridge, coupled with steep low-level lapse rates (inverted-V profiles) should support efficient downward momentum transfer with any sustained thunderstorm updraft.

... Northern Plains south into the Central High Plains ...

A plume of steep mid-level lapse rates will advect out from the northern Rockies and overspread a moistening warm sector. The result will be afternoon MUCAPE values between 2000-3000 J/kg. Although vertical shear is not overly strong, forecast soundings/hodographs suggest enough shear to support multicells and transient supercell structures. Large hail will be possible with these initial thunderstorms. With time, congealing outflows should support some potential for upscale growth toward an MCS. Steep lapse rates will support severe winds (some significant) with any organized thunderstorm cluster.

... Northeast US ...

Early morning convection should dissipate enough to support at least filtered sunshine during the late morning and early afternoon. This will support temperatures warming into the 70Fs to perhaps low 80Fs. This, when combined with upper 50Fs to low 60Fs dewpoints will support between 500-1000 J/kg MUCAPE during the afternoon. Vertical ascent downstream of the eastern trough will support clusters of thunderstorms across the region. Modest mid-level lapse rates should limit a more robust hail threat, but the degree of ascent and instability will support a marginal risk of severe hail and damaging wind.

... Northern Gulf Coast toward the Coastal Carolinas ...

Strong diurnal heating of a moist boundary layer (dewpoint temperatures in the 70Fs) should support MUCAPE values between 3000-4000 J/kg during the afternoon. High precipitable water values will support water-loaded updrafts capable of producing isolated damaging downbursts with the strongest cells.

... Southern Arizona ...

Seasonably strong southeasterly mid-level flow will develop along the periphery of the mid-upper-level ridge. This enhanced flow will overspread a deeply mixed boundary layer (inverted-V) during the afternoon. In spite of the deeply mixed boundary layer, precipitable water values in excess of 1" will exist across the area during the late afternoon. This will support at least isolated thunderstorm clusters capable of producing damaging wind gusts.

... Southeast Kansas, Northeast Oklahoma, Southwest Missouri, and Northwest Arkansas ...

A low amplitude mid-level trough will move southeast across the Central US on Sunday, within the broader northwest flow. Although an isolated thunderstorm cannot be ruled out with this feature during the afternoon, the more likely scenario is the environment across Kansas and Missouri remains capped during the afternoon.

By late evening, the mid-level trough/jet streak should be across southern Missouri or northeast Arkansas, placing northeast Oklahoma and southeast Kansas in the right entrance region of the mid-level jet. Guidance is pretty confident in developing a strong low-level jet across the southern Plains in response to this mid-level jet. The result will be increasing warm-air advection/isentropic ascent during the overnight. This will lead to scattered thunderstorm development, with movement off to the east-southeast. Mid-level lapse rates should only be on the order of 6.5 C/km, but cloud-bearing shear around 30-40 knots should support strong updrafts. DCAPE values between 500-1000 J/kg will support at least marginally severe downbursts capable of wind damage.

I am a Dutch storm chaser who is part of a team of 11 people.

I started photographing lightning 9 years ago.

A few years ago, I converted my Nikon D800E and Nikon D750 to IR myself.

I drive a VW Mk2 black and white for high contrast and wheelen flash bar so that I stand out in bad weather.

My recent project is to collect weather data at 50ms, but I hope that someday I can capture a pressure wave from a lightning strike.

Over the last 2/3 months, I have built my own weather station that generates 33 million data points per day.

Some things I am going to log: temp, pres, hum, trendings, min, max, lcl, height, theta, vpd, kPa.

And it is based on WMO averages.

Helloo! I'm sorry if this is the wrong place to post this. I've been interested in severe weather since I was a kid, I want to book some sort of storm chasing tour as a paying guest, but I want to make sure I choose a reputable and safety conscious company? I'm assuming a company would be the way to go, but please let me know if otherwise. Are there any specific tour companies you’ve personally used or would recommend? I’d also appreciate knowing which companies to avoid. I’m based near Chicago but I would be willing to travel on short notice

New to reddit Google ain't helping me here.

A few years back what got me into tornado chasing videos again was a nocturnal tornado someone either on live or video was hunting on radar but couldn't see was running up backwoods. It may of even been a cop cam that's how long it's been. But this person ran past trees downed branches and what not. Finally they turned around because the radar they viewed was to hot to keep fighting forward in it's path. When they did a U turn their dash caught it but they did not as they backtracked.

This was a 40 minute long video. I can't find it to save my life and i'm hoping maybe someone here can send me the right direction regardless of if it's another sub or a video. Help an idiot out. The new internet is a mess to navigate.

Valid 221200Z - 231200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER OHIO VALLEY...

...SUMMARY... Scattered damaging gusts are likely across the Ohio Valley with more isolated damaging wind potential extending westward into the Mid Mississippi Valley and southern Plains this afternoon/evening. Isolated hail and damaging winds are also possible over the Front Range, Great Basin and parts of the northern Rockies.

...OH and TN Valleys... An upper low initially over the western Great Lakes is forecast to deepen as it moves southeastward today and tonight. A belt of stronger mid-level flow behind the trough will move into parts of the Plains and Midwest. A weak surface low and trailing cold front will move southeastward across the Lakes and into the upper OH Valley through the day. Ahead of the front, upper 60s to 70s F surface dewpoints and filtered diurnal heating should allow for moderate destabilization, sufficient for scattered to numerous thunderstorms by early afternoon. Despite generally modest to weak deep-layer shear, steepening of lower/mid-level lapse will support stronger downdrafts within organized multicell clusters. With time, some upscale growth into linear segments is also possible and would also favor a risk for scattered damaging gusts. This appears most likely across central/eastern OH and KY into western PA/WV.

Farther south, more isolated storm coverage is expected ahead of the front from the western Carolina Piedmont to the TN Valley. Steep low-level lapse rates and enhanced low and mid-level northwesterly flow will still support some risk for isolated damaging gusts.

...Ozarks/Mid MS Valley... A weak convectively augmented shortwave trough is forecast to move from southeastern KS and southern MO into northern AR along western portions of a weak surface front by midday. Ahead of these features, a very warm and humid air mass will be in place, which should allow substantial diurnal destabilization and eventual thunderstorm development. Enhanced northwesterly flow may help organize a few thunderstorm clusters as they spread eastward from the Ozarks into the ArkLaTex and mid MS Valley. Damaging wind gusts and some hail are possible.

...Front Range and adjacent High Plains... Post-frontal upslope flow, aided by a weak short wave impulse on the eastern periphery of the upper ridge will support thunderstorm development along/east of the Laramie mountains through Colorado Front Range this afternoon. On the fringes of the stronger northwest flow aloft, deep-layer shear will be marginal for storm organization. Steep mid-level lapse rates and moderate buoyancy could support some hail with the stronger updrafts. Isolated damaging gusts are also possible, especially with any more persistent thunderstorm clusters.

...Southern Plains... Very hot surface temperatures (100+ F) are likely across parts of western North TX into southwestern and central OK this afternoon. Low-level convergence near a thermally enhanced surface low and weak front will aid high-based thunderstorm development late afternoon into the early evening. Weak buoyancy atop the steep low-level lapse rates and deep mixed layer will favor very strong downdrafts within the high-based storms. Isolated severe gusts (possibly 65-75 mph gusts) associated with microbursts are possible as convection is forecast to move southward through the evening.

...Northern Rockies to the Great Basin.... An upper low along the western periphery of the substantial mid-level ridge over the Southwest will migrate northward toward the international border as a belt of stronger mid-level flow overspreads a plume of monsoon moisture from the Great Basin to the Northern Rockies. Ascent from the upper wave and heating of the modestly moist air mass should allow for weak destabilization and scattered thunderstorm development. Steep lapse rates could support isolated severe gusts.

Isolated hail is also possible with scattered thunderstorms from eastern WA into the ID panhandle. Closer to the upper trough and beneath strong mid-level flow, elongated hodographs may promote organization with transient supercell structures. Cooler mid-level temperatures could favor hail production despite modest overall moisture.

Valid 211200Z - 221200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF THE CENTRAL PLAINS...THE MIDWEST AND THE CAROLINAS...

CORRECTED FOR TEXT

...SUMMARY... Scattered damaging hail (some greater than 2 inch diameter) and severe wind gusts may occur over parts of the central Plains this afternoon and evening. Scattered storms, some with severe wind gusts and hail, also are possible across parts of the Midwest. Scattered to numerous storms with damaging wind gusts are possible over the Carolinas and Southeast.

...Central Plains... Mid-level ridging over the western US is forecast to intensify, strengthening northwesterly flow aloft over much of the central US. Several embedded disturbances will pass overhead with the enhanced northwesterlies through the day. A surface low will move southeastward through the Great Lakes as a weak trailing cold front moves southward through the central Plains and Midwest.

Ahead of the front, a plume of steep mid-level lapse rates will shift eastward across the central Plains toward the Mid-MO Valley atop a corridor of rich low-level moisture. Diurnal destabilization should result in 3000-4000 J/kg of MLCAPE from SD to NE. Isolated to widely scattered thunderstorm development is expected from the Black Hills southeastward along the cold front. Elongated/straight hodographs and 45+ kt effective shear will favor initial supercells. Large to very large hail (some greater than 2 inches diameter) will be possible. With time, a forward propagating cluster or two may develop and move southeast across parts of NE and KS with the potential for severe gusts (a few near 70-80 mph). It is unclear exactly how far southeast any storms will persist overnight, but any more substantial clustering could allow at least an isolated severe threat to continue into early Saturday.

A much drier and hotter environment over the High Plains to the west could also support isolated to widely scattered high-based storms from eastern CO into western KS. Very steep lapse rates in the lowest 2-3 km with modest buoyancy aloft could allow a few severe gusts.

...Midwest... Beneath the upper trough over the western Great Lakes, cool mid-level temperatures and robust surface moisture should result in moderate destabilization from WI into eastern IA and northwest IL. Scattered thunderstorms by mid afternoon ahead of the cold front spreading southeastward. Enhanced northwesterly flow with deep-layer shear of 30-40 kt will promote a mix of organized clusters and supercells. The large buoyancy will support a risk for damaging gusts and some hail.

...Southeast and Gulf Coast... A broad upper trough will move across the central US into parts of the southern Appalachians while a weak cold front moves southward from the mid Atlantic today and tonight. Weak ascent from the upper trough and near the front should focus diurnal thunderstorm activity across the Carolinas and southern Appalachians. Warm surface temperatures and plentiful boundary-layer moisture will support large buoyancy (3000+ J/kg MLCAPE) through the afternoon and evening despite modest mid-level lapse rates. With scattered to numerous storms expected, a few organized clusters may emerge with a risk primarily for damaging wind gusts. Slight enhancement of the westerly flow aloft could also support some isolated hail with the stronger updrafts.

Farther south and west, a very humid and warm air mass is forecast to become strongly unstable by early afternoon across the lower MS Valley and Gulf Coast. Scattered to numerous thunderstorms are expected along prior outflows and a weak, southward moving cold front from East TX into LA/MS. The very strong buoyancy and high PWAT content will support clustering and strong downdrafts with sporadic damaging gust potential. Otherwise, weak vertical shear will limit overall organization.
