The remnants of Tropical Storm Ida moved north-northeast across the lower Mississippi Valley, spreading moisture northward. Some frontal forcing in the mid levels of the atmosphere across southern Indiana and southern Illinois initiated scattered showers and thunderstorms, some of which produced heavy rainfall.

.SHORT TERM...(Tonight through Tuesday night)
Issued at 200 PM CDT Mon Aug 30 2021
All eyes are upon Ida as she makes her inland trek with related
impacts for the Tennessee River Valley. The latest Cams have
picked up on convection this morning in our north, and shifted
this axis to the north this early this afternoon. Notwithstanding
some additional development in our northeast, which has resulted
in some training/locally heavy rain and a couple of flood
advisories, as predicted by previous shift.
We can see the outer edge of Ida moving its rains across West TN
at this writing, and this sets the stage for pops to spike tonight
as it impacts esp our south/east parts of the CWA. Per
collaboration with/on NWC/WPC Conf call, the existing marginal-
slight risk ERO and inherited FFA still looks good over our
southeast counties for couple or three inches, with most of that
falling within a 6 hour time range tmrw morning.
As Ida tracks further east, our pops wane later in the day Tuesday
and effectively end Tuesday evening. With a few peripheral
exceptions, temps will become muted and reside largely in the 70s
once Ida's cloud shield expands over the entirety of the FA.
.LONG TERM...(Wednesday through Monday)
Issued at 200 PM CDT Mon Aug 30 2021
As Ida sweeps into an elongated upper level, East Coast trof,
we'll become dominated by Central U.S. ridging aloft. This high
pressure will present a warm/drying forecast, as dew points drop
thru the 60s Wednesday, into the 50s for Thursday and Friday.
The ridge becomes flattened to a more zonal pattern over the
weekend, and there is model disagreement on the westerlies
dropping a front into our area/supporting pops. Since we're so
dry, we'll stick with persistence strategy on this latter portion
of the forecast over the weekend, and keep pops silent. This means
temps that warm back into/thru the 80s may start to approach 90
again by next weekend.

.AVIATION...
Issued at 656 PM CDT Mon Aug 30 2021
Scattered showers and thunderstorms should tend to lessen in
coverage through early evening with the loss of daytime heating.
VFR conditions will prevail, with localized reductions to MVFR in
association with shower/storm activity. Ceilings will trend to
MVFR overnight into Tuesday morning as rain from the remnants of
Ida spreads northward. The rain will be most persistent and
heaviest in western Kentucky, with lighter and less persistent
rainfall expected further north and west. The rain should taper
off from the west Tuesday afternoon and evening as conditions
improve back to VFR across most of the area. Light winds will
trend northeast tonight, then pick up to around 10 knots on
Tuesday with some gusts of 15 to 20 knots.
