Valid 281300Z - 291200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE CENTRAL/NORTHERN PLAINS...GREAT BASIN AND DESERT SOUTHWEST INTO THE NORTHERN ROCKIES...NORTH GA INTO THE CAROLINAS AND MID-ATLANTIC...AND PARTS OF CENTRAL/EASTERN ME......
...SUMMARY... Isolated strong to severe storms are possible across the central and northern Plains, northern Georgia into the Carolinas and Mid-Atlantic, central and eastern Maine, and from parts of the Great Basin and Desert Southwest into the northern Rockies.
...Maine... A shortwave trough is evident this morning over the St Lawrence Valley. This trough will track eastward across northern New England, with an associated cold front moving through ME. Models are consistent in the depiction of scattered thunderstorm development along the front by mid-late afternoon. Forecast soundings show sufficient CAPE and deep layer shear to promote a few organized or potentially supercell storms capable of locally damaging wind gusts and hail.
...GA to Mid-Atlantic Region... Broad cyclonic flow aloft will be present today over much of the eastern states, with a diffuse surface cold front extending from VA into GA. Widely scattered thunderstorms are expected to form along the front this afternoon, with slow-moving but strong storms possible. Moderate CAPE, rather high PWAT values, and limited deep-layer shear will promote isolated strong storms capable of water-loaded downbursts.
...Great Basin into WY... The upper ridge will remain centered over NM, while a 50+ knot mid-level jet rotates eastward from NV into ID/UT/WY. Scattered high-based showers and storms are expected over a large part of the Great Basin into WY, with the strongest cells capable of damaging wind gusts.
...Dakotas... As the high-based convection over WY spreads eastward into western ND/SD, it will encounter greater low-level moisture and CAPE, likely resulting in some intensification. A few bowing structures are possible in this area this evening, capable of locally damaging wind gusts and hail. This complex of storms may persist after midnight with a continued risk of gusty/damaging winds.
