...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...

...DISCUSSION...
An upper-level ridge will move eastward across the Intermountain

Great Plains. At the surface, a moist airmass will be in place
across the Florida Peninsula and in the southern half of Texas. On
the northern edge of this airmass, warm advection will take place in
north Texas and southern Oklahoma this evening, where a few elevated
thunderstorms could develop. A few thunderstorms may also form in
northwestern Colorado this evening as a subtle shortwave trough
moves through the central Rockies. Thunderstorms may also develop in
parts of the Great Lakes this afternoon and evening ahead of an
upper-level trough. No severe threat is expected across the
continental United States today or tonight.
