.DISCUSSION...
Issued at 118 AM CDT Fri Oct 3 2025
A ridge of high pressure at the sfc and aloft will begin to build
west for the upcoming weekend. A few of the 0z CAMs are still
hinting at just enough lingering weakness to support a stray sprinkle
this afternoon, mainly along I-64 where subtle PVA remains from a
shortwave. Thermo profiles are not quite as impressive compared to
yesterday, with less instability and meager moisture around 800 mb
despite very steep low-level lapse rates. Due to low confidence,
kept NBM PoPs silent and only added a slight sprinkle mention for
this afternoon using blends of the NAMNest and NSSLWRF. Overall,
would expect coverage to be more limited if any as it is also
possible the ridge suppresses any pcpn north of the FA.
The aforementioned high pressure will help keep temperatures above
normal through the weekend with highs well into the 80s. Nighttime
lows trend more into the 50s as lower dewpoints and drier air
in the column will support slightly better radiational cooling.
By Monday, an influx of Gulf moisture will begin to occur as a
more amplified trough begins to move downstream from Canada
towards the Great Lakes region. Scattered showers and storms
remain progged for Monday and Tuesday with model consensus now
showing a cold front moving through Tuesday night into Wednesday
morning. With the better forcing remaining north of the FA, QPF
amounts remain light and will likely provide very little relief
for the ongoing drought conditions, with only a few tenths to a
half inch progged.
Temperatures trend near to slightly below normal into the latter
half of next week behind the cold front well into the 70s with lows
progged in the upper 40s to lower 50s. With a 1032 mb high pressure
building into the Ohio Valley, it will certainly feel a lot more
like fall with ample dry weather conditions.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1122 PM CDT Thu Oct 2 2025
VFR conditions are forecast through the TAF period. There is a
small risk for patchy ground fog mainly at CGI or any areas
adjacent to water bodies, but broader conditions do not appear
favorable for significant fog. Light to moderate southwesterly
winds are forecast during the day tomorrow. Isolated showers are
again possible in the late afternoon but the probability is too
low for any TAF mention for now.
