..no severe thunderstorm areas forecast...
mainly isolated thunderstorm activity is forecast across the Central
Plains and middle Missouri River valley and southward into the
southern High Plains and Rio Grande Valley. Elsewhere...a few
storms will be possible in the southern Florida Peninsula.
The primary upper-level feature for thunderstorm activity will be a
shortwave trough moving from the northern and Central High plains eastward into
the upper Midwest and middle MO River Valley during the day 3 period.
An associated cold front extending south-southwestward from a low over S-central
Canada into the Central High plains...will move eastward across portions of
the northern and Central Plains states during the day as southerly low-level flow
transports a narrow plume of modest low-level moisture northward into the
Central Plains. Isolated thunderstorms are forecast to primarily
develop during the afternoon/evening over the Central Plains and
perhaps later farther east and S over western MO and OK. Modest middle-level
lapse rates and limited moisture will likely negate appreciable
severe potential across the plains states.
