Area Forecast Discussion
National Weather Service Lincoln IL
1101 PM CDT Sat Apr 14 2018

.UPDATE...
Issued at 850 PM CDT Sat Apr 14 2018

Cold front has edged into extreme east and southeast Illinois this
evening accompanied by a band of showers, which extends further
west to along and east of a Peoria to Springfield line. Short
term guidance suggests another wave of rain will move north
out of southern Illinois and affect about the eastern half of
the forecast area overnight. Further west, the large and deep
upper low now centered over southern Iowa will shift slowly
into our area by tomorrow evening bringing unseasonably cool
weather to the area and another round of showers, especially
tomorrow afternoon across our north and west, as the very cold
temperatures aloft associated with 500 mb low move across the
region. By late tomorrow afternoon and especially tomorrow night,
the rain will mix with and then become mainly scattered snow
showers overnight accompanied by a gusty northwest wind and
temperatures dropping into the mid 20s north to around the
freezing mark far southeast IL.

Made some adjustments to the precipitation trends for the
overnight hours, especially across the east. We should have the
updated zones out by 915 pm.

.SHORT TERM...(This evening through Sunday)
ISSUED AT 219 PM CDT Sat Apr 14 2018

Early afternoon surface map showed low pressure near Springfield,
with a cold front extending south and the oscillating warm front
east to near Champaign. Showers have been ramping up quite a bit
over western Illinois to as far east as Peoria and Springfield.
Eastern CWA is currently dry. SPC mesoanalysis shows surface
instability has been limited so far, despite some thinning of the
clouds that occurred earlier in eastern Illinois. However, RAP
guidance shows potential for 500-1000 J/kg of surface CAPE by
late afternoon in areas east of I-57. Have kept a mention of
isolated/scattered thunder ahead of the low/cold front, which
should be near Champaign by 7 pm.

Widespread showers expected overnight, as the large upper low in
northeast Nebraska moves east, and a new surface low reforms
across the Tennessee Valley. The eastern CWA will be most impacted
by the rain, as the west comes under the influence of the dry slot
currently in western Missouri. However, as the upper low drifts
into western Illinois toward midday Sunday, the showers will be on
the increase again.

.LONG TERM...(Sunday night through Saturday)
ISSUED AT 219 PM CDT Sat Apr 14 2018

Looks like the 3rd Sunday in a row with some snow potential across
the CWA, as colder air is drawn in behind the departing upper low.
Rain to snow changeover may begin in the far northwest CWA as
early as late afternoon, but a more rapid changeover is expected
in the evening. Only a minor dusting is currently expected, mainly
north of I-74. Given the first Sunday with snow was on Easter,
here's hoping the myth of "7 Sundays of rain after an Easter
rain" doesn't apply to snow as well.

Freeze potential still looks strong for Sunday and Monday nights,
with most of the CWA dropping into the 20s. Right now, the growing
season is considered advanced enough to warrant frost/freeze
headlines south of I-70, though areas to the north likely had some
planting done over the recent warm spell. With the southeast CWA a
bit more uncertain with freezing conditions, will hold off on any
headlines for now.

Not a lot of change in the forecast the remainder of the week. The
midweek storm system still looks to largely track north of us,
though the GFS hints at some light precipitation with the trailing
cold front on Wednesday. Right now, will limit any PoP mention to
the northern CWA closer to the low track. Late in the week,
another strong system will take shape over the central Plains.
The GFS is much quicker with this system, bringing rain into the
area as early as midday Saturday. However, the ECMWF is about
18-24 hours slower. Will keep PoP's on the lower side (around 30
percent) at this point and will watch things shake out over the
next several runs.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1100 PM CDT Sat Apr 14 2018

A large weather system to our west will continue to edge slowly
towards our area over the next 24 hours. Mainly MVFR with
occasional IFR and LIFR conditions expected as the system moves
across our area with the lower cigs and vsbys across our north. An
area of showers continues to affect our central and eastern TAF
sites late this evening with another wave of rain moving north
into at least the I-57 corridor with some models suggesting the
rain may occur further west late tonight into Sunday morning. We
should see a break in the precip for a brief time Sunday morning
before scattered rain showers move across parts of our area, again
favoring PIA and BMI with more widely scattered coverage further
south. West to northwest winds of 8 to 13 kts tonight will be more
westerly on Sunday with speeds increasing to 12 to 17 kts by late
morning with gusts up to 25 kts at times in the afternoon.
