Area Forecast Discussion
National Weather Service Lincoln IL
907 PM CDT Sat Jul 22 2017

.UPDATE...
Issued at 907 PM CDT Sat Jul 22 2017

Updated forecast around 8 pm to remove heat products. Current
forecast still looks good with chance of showers and storms south
of I-72 to Danville line. Temp/wind forecast looks fine so
additional update not needed at this time.

&&

.SHORT TERM...(This evening through Sunday)
ISSUED AT 314 PM CDT Sat Jul 22 2017

19z/2pm surface analysis shows a weak frontal boundary extending
from southern Lake Michigan westward to the Iowa/Missouri border.
The airmass ahead of the front is still recovering from early
morning convection: however, latest LAPS data indicates CAPE
values have increased to 2500-3500J/kg...with a max of over
4000J/kg noted south of I-70. Despite the increasing instability,
storms have yet to re-develop. One reason is because much of the
KILX CWA is currently under a region of subsidence in the wake of
the morning storm complex, as evidenced by an anticyclonic curl on
water vapor imagery across southeast Illinois. As this feature
tracks further east and the cold front sinks southward, widely
scattered thunderstorms will develop along/north of I-74 within
the next 2-3 hours. Storms will become more widespread across
east-central/southeast Illinois by mid to late evening, with a few
of the storms potentially becoming strong to severe east of I-57.
Have carried low chance PoPs everywhere during the evening, with
high chance across the east accordingly. The showers/storms will
drop further southward and will mainly be confined to the SE
counties after midnight.

The cold front will settle into the Ohio River Valley on Sunday:
however, drier air will only trickle southward into the region...
with dewpoints still expected to be in the lower 70s. Meanwhile, a
vigorous short-wave trough noted on latest water vapor over
southern Manitoba will track southeastward into Michigan.
Increasing lift along/ahead of the trailing vort max will interact
with the ample boundary layer moisture to trigger widely scattered
thunderstorms across eastern Iowa into north-central Illinois
Sunday afternoon. With CAPE values ranging from 2500-3500J/kg and
0-6km bulk shear increasing to around 40kt, a few of the cells
could potentially produce marginally severe wind gusts and hail.
Have included low chance PoPs along/north of a Jacksonville to
Danville line during the afternoon...then further south to just
north of I-70 in the evening. Do not think areal coverage will be
that substantial...and think any storms that fire will dissipate
after sunset as daytime instability wanes.

.LONG TERM...(Sunday night through Saturday)
ISSUED AT 314 PM CDT Sat Jul 22 2017

Once the upper wave passes to the east, high pressure will build
into the Midwest early next week...bringing cooler and less humid
conditions to central Illinois. High temperatures will drop into
the middle to upper 80s for Monday and Tuesday before rebounding
back into the 90s by Wednesday. Models are showing a significant
trough digging across the Great Lakes by late in the period,
which will allow another airmass change to arrive by the end of
the week. 12z Jul 22 GFS has sped up the initial short-wave and
its associated cold front, with scattered showers/thunder pushing
into west-central Illinois as early as Wednesday afternoon.
Meanwhile, the ECMWF remains about 6-12 hours slower with precip
arrival. At this point, it appears the best rain chances will
materialize Wednesday night through Thursday night, with all
solutions taking the front south of the region by Friday. As a
result, will carry high chance PoPs during that time, with
cooler/drier weather returning for Friday and Saturday.

.AVIATION...(For the 00Z TAFS through 00Z Sunday evening)
Issued at 628 PM CDT Sat Jul 22 2017

Storms are finally beginning to develop along the front in
northern IL. However, as they move east they begin to weaken. This
front will drift south this evening. So thinking now is that pops
for PIA and BMI will be very small and precip will be south of
them. So will not have VCTS for them. SPI/DEC/CMI however could
still see some precip/ts as the front drops near them and
convection from the west could begin to move into central IL or
storms will develop on the front as it moves little south. So will
have VCTS for these three sites for several hours this evening. By
midnight all sites should be dry and front should be south of
SPI/DEC/CMI. Any precip that occurs this evening could result in
fog toward morning given the mostly clear skies and lighter winds
overnight. Winds will become northerly tomorrow behind the front
and am expecting some scattered CU to develop tomorrow.
