.CORRECTION...

SHORT TERM... (This afternoon through Saturday Night)
Issued at 1206 PM CDT Thu May 9 2024

Cooler weather in place and it`s a little less humid today. Temps
are in the upper 60s to lower 70s right now. Another cold front is
located upstream and stretches along the OH river westward across
southern IL. This boundary will be moving through tonight with
partial clearing expected.

The upper levels will be a touch on the active side through
Saturday. A series of weak shortwaves will work southward across our
area and may bring some light shower activity mainly across our
east. Latest nbm numbers however, indicate that pops will be on the
low side. Also, as good news, any additional rainfall will be just a
tenth of an inch at best and mainly over the eastern half of the
mid state.

Temperature wise, its looking cooler than it has been. Lows over the
next few days will be in the 50s with highs in the 70s.

.LONG TERM...
(Sunday through next Thursday)
Issued at 1206 PM CDT Thu May 9 2024

In the extended forecast, we will kick off the period with some
upper ridging. The ridge axis will quickly move east, however, and
give way to our next weather system. This system will take the form
of an open wave. The associated frontal system will offer little n-s
extension and instabilities will be weak. Nevertheless, showers and
thunderstorms will return beginning Monday night, but the activity
looks like a general risk. Otherwise, rainfall amounts look like
maybe a half inch.

After a brief break on Wednesday, look for more showers and tstms to
return. This system looks more potent with a surface low tracking
northeastward across the upper midwest. The southwestward frontal
extension lacks organization, but 60 knots at 850 mb could end up
being problematic if instability levels increase with time.
As for now, no day 7 or day 8 spc inclusion. Rainfall totals at
this point look like up to one inch or so.

For the extended temps, values looking close to normal for mid May
with lows upper 50s to lower 60s and highs mid 70s to lower 80s.

.AVIATION...
(18Z TAFS)
Issued at 1217 PM CDT Thu May 9 2024

The overly active weather pattern has mercifully come to an end.
We still have a cold front upstream today but the westerly wind
flow should remain in the moderate magnitude level. The front will
work across our area this evening but no precip is expected.
Upper troughing will prevail on Friday with a shortwave impulse
tracking southward. At that time, cigs will be close to IFR limits
but should stay closer to the 3kft level. Will include VCSH for
the CSV area for late in the taf period.
