..no severe thunderstorm areas forecast...
scattered thunderstorms are expected to develop on Wednesday across
the Appalachian Mountains...Gulf Coast states and along much of the
eastern Seaboard. Scattered thunderstorms should also develop in the
Desert Southwest eastward into the Rocky Mountains. Isolated
thunderstorms will be possible across the Mississippi Valley...Great
Lakes region...Ohio and Tennessee valleys and in the northcentral
states on Wednesday afternoon.
An upper-level ridge is forecast to amplify across the upper Midwest
and western Great Lakes region on Wednesday as southwest flow remains in
place across the northwestern third of the nation. Warming surface temperatures on
Wednesday should result in scattered thunderstorms in the Desert
Southwest eastward into the Rocky Mountains aided by topographic forcing.
Scattered thunderstorms are also expected to develop Wednesday
afternoon in a moist airmass across Florida...the Gulf Coast
states...southern Appalachians and Carolinas. Due to limited
deep-layer shear across the Continental U.S....no severe thunderstorm activity
is expected Wednesday or Wednesday night.
