...A surge in heat and humidity expected for the Middle Mississippi and
...Flash flooding and severe weather possible across portions of the
Midwest on Saturday...
Heat and humidity will make a return to the Middle Mississippi and Ohio
Valleys late this week as a frontal boundary stretched from the Central
Plains to the Lower Mississippi Valley begins to surge northeastward as a
warm front. Meanwhile...showers and thunderstorms will continue to ignite
ahead of a seasonably strong cold front pushing through the north central
U.S. on Friday. These storms will be capable of producing heavy downpours
and severe weather...especially as they propagate southeastward into a
moist and unstable airmass setting up across the Midwest on Saturday.
A plume of moisture streaming off the Eastern Pacific will fuel additional
days of scattered afternoon convection across the Southwest and Central
Rockies Friday and Saturday. Elsewhere in the West...temperatures will be
on the rise over the Northern Rockies and Intermountain West this weekend
as an upper ridge sprawled across the south central U.S. builds northward
into the region.
Pleasant conditions will prevail in the wake of a cold front pushed well
off the New England and northern Mid-Atlantic coasts on Friday.
However...the tail end of the boundary will linger over the Southeast and
Gulf Coast states...helping to foster shower and thunderstorm activity
Friday and Saturday.
