.KEY MESSAGES...

- Strong to severe thunderstorms remain possible this evening,
  mainly in the north early this evening and in the southeast
  later this evening, with all hazards (isolated tornadoes, large
  hail, and damaging winds) likely. SPC maintains a slight risk
  (level 2 of 5) in our north and southeast for the rest of the
  day. An enhanced risk (level 3 of 5) is on the edges of our
  north and southeast as well.

- Strong gusty northwest winds will increase tonight after a cold
  front moves into the area. Gusts will reach 35 to around 45 mph
  from 9 pm tonight through the overnight hours.

- Much colder temperatures will follow the cold frontal passage
  tonight, dropping into the 20s by morning. This will be around
  50 degrees colder than this afternoon's highs, which have been
  in the lower to middle 70s. Combined with the strong winds, wind
  chills will reach into the single digits over most of the area.

.UPDATE...
Issued at 831 PM CST Tue Feb 27 2024

The severe threat for areas north of interstate 74 has ended for
the night. Now the area of interest is near and south of a Shelby
to Edgar county line. A line of strong thunderstorms is expected
to form along the cold front as it moves through southeastern
Illinois. Currently, the cold front has just passed the interstate
55 corridor, with temperatures dropping significantly behind it.

.SHORT TERM...  (Through Late Wednesday Night)
Issued at 325 PM CST Tue Feb 27 2024

A strong synoptic system will move into the area late this
afternoon and bring several weather concerns to the CWA from this
evening and during the overnight hours. A tight moisture gradient
has developed along northern IL into northern MO and southern IA
this afternoon and appears looking at vis satellite imagery that
some agitate CU has begun to develop, possibly indicating the area
of initial development for later this afternoon. CAMs have
fluctuated today on location of initial development but have also
included northeast parts of the CWA...Champaign and Vermilion
counties. Storms look to develop and then move northeast away from
the CWA after several hours. CAMs have also shown another area of
development in our far southeast as well...also highlighted by the
enhanced outlook are from SPC. Unfortunately, the airmass
in-between these two areas appears to be capped, as evident on the
U of I observed sounding and HiRes guidance forecast soundings.
The area of convection in our southeast will likely continue into
the night as the cold front approaches from the northwest and
west.

The temp gradient behind this front is very tight and the CAA is
quite impressive. This should bring very strong winds to the area
during the evening and into the overnight hours. Guidance
suggests that winds of 35 to 40 mph is likely. However, some
ensemble members should possibility of winds of around 45 mph
part of the time. Though this may only occur for several hours
this evening and possibly overnight, have gone ahead and issued a
wind advisory from 9pm to 6 am tomorrow for the northern parts of
the CWA...from Fulton to Mclean Co and to the north.

Record highs have been seen today and it will be a huge shock to
see temps fall around 50 degrees by tomorrow morning. The strong
winds tonight will also cause wind chills in the single digits and
lower teens over most of the area.

Tomorrow, winds will be on the decrease as the cold high pressure
quickly pulls away from the area. Highs tomorrow will get above
freezing, but only into the middle to upper 30s. Temps tomorrow
night will be cold again and very similar to tonights. The only
positive will be winds will be light enough so that wind chills
will not be bad.

Auten

.LONG TERM...  (Thursday through Next Tuesday)
Issued at 325 PM CST Tue Feb 27 2024

The main item in the extended is how fast the temps will return to
above normal for the last half of the week, into the weekend and
in the beginning of next week. Highs will reach back into the 60s
and 70s for Sat through Mon. The warmer temps also mean and return
to southerly winds and likely some unsettled weather. The chance
of rain will return the beginning of next week after and decent
stretch of dry weather.
