.DISCUSSION...
Issued at 245 AM CDT Mon Oct 6 2025
The pressure gradient relaxes today, leaving us with much calmer
winds than yesterday, as the cold front progresses eastward. Highs
today will be in the 80s once again, with lows in the upper 50s to
mid 60s. Increased moisture advection from the south ahead of the
cold frontal passage will bring a chance for precipitation to
southeastern IL this afternoon. Timing for this cold front shows it
entering the northwestern counties of the CWA by this evening
(~00z). Showers and thunderstorms will accompany the cold frontal
passage, lingering into Tuesday. The precipitation should be out of
the area by 00z Wednesday (7pm Tuesday). It looks like with the cold
front precipitation and the precipitation moving north out of
southern IL, there is an area between I-72 and I-70 where there
could be a lull in heavier rainfall.
QPF through Wednesday 00z is showing 0.5-1 inch south of I-70,
upwards of 0.75 inches north of I-72, and less than 0.25 inches
between I-72 and I-70. Some locally higher amounts are possible
where a heftier thunderstorm may pass through. Behind this front,
another period of dry weather sets up for what looks like 5-7 days
as another high pressure scoots in.
Temperatures will cool into the low to mid 70s for highs behind the
front before warming back into the 80s for the weekend. Wednesday
and Thursday will be the coolest days we have seen in quite
awhile, with highs in the low 70s, near 60, and lows in the upper
30s to mid 40s.

.AVIATION...  (For the 06z TAFs through 06z Monday Night)
Issued at 1223 AM CDT Mon Oct 6 2025
Main aviation concerns will be in the latter part of the forecast
period. Through about 00z, south/southwest winds average about
6-10 knots, but an approaching cold front will switch them around
to northwest at KPIA early to mid evening. Scattered showers
increase during the evening, with a few storms possible with the
front. Meanwhile, a surge of MVFR ceilings will push northward
late afternoon into the evening. Main impacts appear to be at KCMI
and potentially KDEC, with 40-50% probabilities of ceilings below
3000 feet by 02-03z. Some concern this may become IFR late in the
period, with NBM probabilities of ceilings below 1000 feet around
40% at these sites, and will need to watch this for potential
inclusion in the next TAF set.
