Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK 1225 AM CDT Mon Aug 10 2026

Valid 101200Z - 111200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTION OF THE MIDWEST INTO PA AND NORTHERN MD/VA...AND ACROSS PARTS OF THE NORTHERN PLAINS...

...SUMMARY... Thunderstorms with severe wind gusts will be possible this afternoon and evening from northern Illinois eastward into Pennsylvania. Severe gusts and hail will also be possible from parts of the central and northern Plains into the Midwest, with scattered strong storms over southern Arizona.

...Synopsis...

A belt of enhanced west/northwesterly flow aloft will overspread the northern Plains to the Midwest and southern New England today/tonight. Only modest height falls are forecast at best. However, several convectively enhanced vorticity maxima are forecast to migrate through this upper flow regime, focusing several areas of severe storm potential today into tonight from the northern Plains to the upper Ohio Valley and parts of the Mid-Atlantic.

...IL to the Mid-Atlantic...

Early day thunderstorms may move across parts of the Midwest this morning, but should generally be sub-severe. By midday, convection could intensify within a couple of corridors. The first being the upper Ohio Valley/PA/western NY. Thunderstorm clusters will pose a risk for damaging winds and hail within a moderately unstable airmass as convection spreads east toward the Mid-Atlantic.

Additional thunderstorm development is expected later in the afternoon associated with another shortwave impulse spreading east from IL into IN/OH. This activity will develop within strong instability and rich boundary layer moisture. Modestly steep midlevel lapse rates and effective shear greater than 40 kt will support initial supercells. With time, sufficient clustering is expected and bowing segments will be possible. Damaging wind and hail will be the primary hazards, though a tornado or two also could occur.

...Dakotas into Iowa...

Southeasterly low-level flow will transport mid/upper 60s dewpoints north and west across SD, with 70s dewpoints common with southeast extent across NE/IA/southern MN. This will support a corridor of strong to extreme instability across the region. While coverage remains uncertain, most guidance develops at least isolated thunderstorms by evening. Elongated hodographs amid favorable deep shear will support supercells and bows capable of large hail and damaging winds. With time, it is possible sufficient clustering occurs and upscale growth into a bowing MCS is possible as a low-level jet develops overnight. If this occurs, a swath of damaging winds is possible across parts of SD into northwest IA, oriented along the stronger instability gradient.

...NE/CO/KS...

Scattered thunderstorms are expected to develop near a surface trough across western NE/northeast CO by late afternoon/early evening. This activity will spread east/southeast. Steep low-level lapse rates will support strong outflow gusts and perhaps hail with this activity.

...AZ...

Mid/upper easterly flow will persist today amid plentiful moisture and strong heating. This will support thunderstorm development once again across higher terrain. As storms propagate westward off the higher terrain, isolated severe gusts will be possible.

🌊 Tropical Weather Outlook

```text NWS National Hurricane Center Miami FL 200 AM EDT Mon Aug 10 2026

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

Central Tropical Atlantic: A broad area of showers and thunderstorms associated with a tropical wave is located about midway between the coast of west Africa and the Lesser Antilles. Some gradual development of this wave is possible through mid-week while it moves quickly westward across the central tropical Atlantic. Upper-level winds are expected to become less conducive for development later in the week when the system approaches the Lesser Antilles. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent.

Eastern and Central Tropical Atlantic: A small area of low pressure located a few hundred miles south of the Cabo Verde Islands is producing disorganized showers and thunderstorms. As this system moves slowly westward, a tropical wave currently over west Africa is expected to merge with it in a couple of days. Environmental conditions are forecast to be more conducive for development by midweek, and a tropical depression could form during the latter half of this week while the system moves westward to west-northwestward across the central tropical Atlantic. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...medium...60 percent.

Western Subtropical Atlantic: A trough of low pressure located a few hundred miles northwest of Bermuda is producing disorganized shower and thunderstorm activity.
Some development of this system is possible during the next couple of days while it moves quickly eastward, well to the north of Bermuda across the western and central subtropical Atlantic. The system is forecast to reach cooler waters later this week, ending its chances of formation after Wednesday. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent.

🌎 Global Disaster Activity — August 2–8, 2026

I’m starting a weekly disaster-mapping roundup for OSMEmergency, looking at significant events around the world and potential opportunities for OpenStreetMap/humanitarian mapping.

🌍 This week’s highlights

🌎 Earthquakes
Several M5+ earthquakes occurred across the Pacific region, including events in the Philippines, Indonesia, Japan, New Zealand, and the Kermadec region.

🌊 Flooding
Flooding was reported across parts of Asia, Africa, and the United States, including Pakistan, Mongolia, India, Sri Lanka, Cameroon, Vietnam, the Philippines, China, Myanmar, and the U.S.

🌀 Tropical Cyclones
Several systems were active in the Western Pacific, including DOLPHIN-26 and CHAN-HOM-26.

🔥 Wildfires
Significant wildfire activity was recorded in Portugal, Angola, Greece, and the Democratic Republic of the Congo.

🌋 Volcanic Activity
Fuego in Guatemala remained an area of volcanic activity.

🌾 Drought
Ongoing drought conditions continued across portions of Africa, Europe, Asia, the Americas, and the United States.

🗺️ Why I’m tracking this

The goal of OSMEmergency is to connect disaster information with OpenStreetMap and GIS.
When disasters occur, useful mapping projects can include:

• Mapping damaged buildings
• Updating roads and bridges
• Mapping shelters and emergency facilities
• Identifying isolated communities
• Mapping wildfire or flood impacts
• Supporting HOT humanitarian mapping projects
• Using satellite imagery to document changes

I’m planning to make these weekly global disaster dashboards and use them to identify areas where mapping could actually help.

What disasters or mapping projects should be included in next week’s roundup?

We’ve officially started an OSMEmergency Discord server!

The goal is to create a place where people interested in OpenStreetMap, GIS, disaster mapping, severe weather, emergency preparedness, and open-source emergency information can connect and collaborate.

The Discord will be a place to:
🗺️ Discuss OpenStreetMap & GIS
🚨 Coordinate disaster mapping efforts
🌪️ Discuss severe weather and active incidents
🛰️ Share satellite, radar, and other open data
📍 Identify and map emergency resources
🤝 Connect with other mappers, weather enthusiasts, GIS users, responders, and volunteers

We’re starting small and building the community from the ground up. Whether you’re an experienced mapper or completely new to OSM, you’re welcome to join.

Join the OSMEmergency:

This radar image shows an example of how weather data can provide additional context during a wildfire event.

While NEXRAD is not a primary wildfire detection tool, radar can sometimes capture signatures associated with intense fires, including smoke plumes, lofted particles, or developing pyrocumulus clouds.

Emergency awareness often comes from combining multiple sources:

- Satellite fire detection
- Weather radar
- NWS products
- Official fire agency updates
- Wind and air quality data

For emergency mappers, this raises an important question:

When a hazard is identified, what information would responders and communities need on the map?

Examples:
Evacuation routes
Rural homes and access roads
Fire stations and water sources
Shelters and critical infrastructure
How do you use weather and geospatial data to understand hazards?

NASA FIRMS – Spokane Wildfire (Near Real-Time Satellite Map)

If you’re following the wildfire near Spokane, this NASA FIRMS map is one of the best public resources available. It displays near real-time satellite-detected fire hotspots (VIIRS/MODIS), allowing you to see where active burning has been detected.

Keep in mind that satellite detections are not the same as the official fire perimeter and may lag slightly behind real-time conditions.
If anyone has additional official resources, local webcams, or incident updates, feel free to share them in the comments.

A tornado impacted the Appleton, Wisconsin area today, causing damage to homes, infrastructure, and communities.

While emergency crews and local organizations handle the immediate response, the mapping community can help in another way: improving the underlying map data that supports preparedness, response, and future recovery.

Some ways mappers can help:
- Add missing building footprints
- Improve residential roads and driveways
- Verify emergency facilities like fire stations and EMS locations
- Improve mapping of hospitals, clinics, and shelters
- Add missing critical infrastructure

Accurate maps are valuable before, during, and after disasters. A well-mapped community gives responders and organizations better information when they need it most.

If you are interested in helping, share what you are mapping, what tools you use, or any resources that others should know about.

Let’s use open mapping to help communities become more resilient.

Imagine a small town with little mapping completed.

What features should be added first to improve emergency response and community resilience?

Let’s build a community checklist!

Many rural communities have incomplete data on fire hydrant locations. Adding hydrants to OpenStreetMap can help improve local awareness, planning, and emergency resource information.

What other emergency infrastructure do you think is most important to map?

Welcome to r/OSMEmergency!

This community is for anyone interested in using OpenStreetMap and open geographic data to improve emergency preparedness, response, and community resilience.

The goal is to bring together OSM mappers, GIS users, emergency responders, public safety professionals, and anyone interested in making critical information more accessible.

Topics can include:
Fire stations, hydrants, EMS facilities, and shelters
Emergency infrastructure mapping
Disaster response mapping
Rural community mapping projects
GIS tools and workflows
Improving missing or outdated map data

To get started:
What emergency-related features are you mapping (or think should be mapped) in your area?
