.SHORT TERM /THROUGH FRIDAY/...
Issued at 245 PM CDT Thu Sep 12 2024

Quiet weather is expected tonight with increasing high and mid-
level clouds as moisture associated with Tropical Depression
Francine spreads northward. Overnight lows will be in the upper
50s to lower 60s.

The remnant tropical low will stall over NE Arkansas overnight
into Friday, and with high pressure located across eastern
Canada will lead to steady easterly flow locally. We`ll be
looking at another warm day with highs in the mid 70s far south
to lower 80s central and north. Increasing mid to low clouds
south of I-80 through the morning and afternoon could be
accompanied by a few isolated showers or sprinkles, but most of
the area won`t receive measurable rain. The low chances for a
few showers will spread into the NW forecast area later Friday
afternoon into Friday night.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 245 PM CDT Thu Sep 12 2024

Saturday and Sunday...SE low to mid level flow north of the
remnant tropical low in the Lower Mississippi Valley will lead
to steady moisture advection locally, with PWATs reaching
to near 1.50". The increase in moisture will be reflected at
the surface too, as dewpoints reach the mid to upper 60s which
is fairly high for mid September. Highs in the mid/upper 80s
combined with the aforementioned humid conditions will likely
result in periods of isolated to scattered showers and storms;
although confidence on how widespread is low. Latest models are
in fairly good agreement on higher chances for scattered
showers/isolated storms on Sunday.

Next Week...Very warm and mainly dry conditions are expected
with a highly amplified upper ridge expanding over the Central
U.S. NBM forecast highs are in the mid to upper 80s which is
about 5-10 degrees above normal. There is no sign of fall weather
for the next 7+ days.
