.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 217 AM CDT Tue Jul 16 2024

The widespread storms that brought rather significant wind
damage, heavy rains, and likely a few tornadoes has moved well
to the east overnight. The front has not moved very far south,
and remains positioned from Kirksville to Quincy, and it
continues to be dealing with persistent training storms just
south of Hancock and McDonough counties. These storms likely
brought flash flooding earlier tonight in Henderson and
McDonough, with 2-4 inches falling in that area.


Today will be the transition day as we slowly advect in drier
air, and eventually, cooler air. To start the day, some shallow
fog is again possible, especially over eastern Iowa where skies
have been clear. As the day progresses, dew points will
gradually fall into the mid to upper 60s, and while not dry air,
it should feel much more comfortable outside with temperatures
peaking in the lower 80s north to mid 80s central and south.

.LONG TERM /THURSDAY THROUGH MONDAY/...
Issued at 217 AM CDT Tue Jul 16 2024

Much cooler weather looks to be in place through the weekend,
with an upper trof building into the Great Lakes. Dry weather
will persist through the end of the work week, followed by some
very low pops for activity potentially on the western side of
the upper trof as we approach the weekend. Highs in the upper
70s to lower 80s are forecast through the weekend, followed by
a slight increase to the lower to mid 80s for early next week.

We`re all looking forward to this break in the non-stop heat-
humidity-violent-heavy storms of the past week. Good riddance!
