...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Tuesday.
...Synopsis and Discussion...
Upper pattern across the CONUS Tuesday morning is forecast to be
characterized by generally modest flow and several relatively weak
shortwave troughs. A slow-moving shortwave trough over the Lower MS
Valley will contribute to numerous thunderstorms from east TX to the
central Gulf Coast while another shortwave fosters scattered
thunderstorm development as it moves across the Northeast. Weak
vertical shear and modest buoyancy will limit the severe potential.
Farther west, scattered thunderstorms are again expected within the
monsoonal airmass over the Southwest and central Rockies.
Southwesterly flow aloft and modest large-scale forcing for ascent
attendant to a closed low drifting southeastward out of British
Columbia will promote thunderstorm development over the northern
Rockies/northern High Plains. Severe thunderstorm risk will be
tempered by modest vertical shear.
