Area Forecast Discussion
National Weather Service Lincoln IL
330 PM CDT Sun May 17 2020

.SYNOPSIS...
Issued at 330 PM CDT Sun May 17 2020

A cold front will move from central Illinois into Indiana this
evening, resulting in showers and thunderstorms in central and
eastern Illinois this evening. An area of low pressure associated
with the front will move into Indiana by early Monday morning, and
then come to an abrupt halt. This will keep clouds and scattered
showers in the forecast for much of Illinois Monday and Tuesday,
along with cooler temperatures in the 60s.

&&

.SHORT TERM...(This evening through Monday)
ISSUED AT 330 PM CDT Sun May 17 2020

A cold front, moving just east of the I-55 corridor at 3 pm will
set the stage for the weather this evening in central and eastern
IL. Strong low level moisture transport, increasing shear and a
coupled upper level jet/upper divergence will allow for expansion
of thunderstorms east of I-55. Still some question as to the
severity of the storms with instability limited to a narrow ribbon
of CAPES of 1500-2000 J/kg mainly in east central Illinois early
this evening. Due to precipitable water values of 1.6-1.8 inches
and the strong moisture transport in the low levels, the t-storms
should be efficient at producing heavy rain, so will keep the
Flash Flood Watch going until 7 pm east of I-55.

Most of the short range models and CAMs are showing that the
t-storms should exit eastern IL by 9 pm with the stacked surface
low in NW IL, drifting slowly eastward. Wrap around clouds and
spotty showers are expected to drop south and southeastward into
central IL toward daybreak. During the day Monday, the associated
upper low will drift SSE into central IL. This will keep clouds
and scattered showers across the forecast area, along with cool
temperatures in the lower 60s.

&&

.LONG TERM...(Monday night through Sunday)
ISSUED AT 330 PM CDT Sun May 17 2020

The short and medium range models are in fairly good agreement
that the upper low drifting through central IL Monday will
influence our weather through midweek. The presence of Tropical
Storm Arthur moving along the east coast will be the main culprit
for keep the upper low in the vicinity of the Ohio Valley into
Thursday, before finally getting a push out of the region. With
the position of the low expected to be in the lower Ohio Valley
Tuesday, another cloudy and showery day will be in store for
central and eastern IL. With the low wobbling a bit farther south
and then back northwest toward the upper OH Valley midweek,
mostly cloudy and cool conditions will prevail with spotty showers
Wed and Thu.

After the low finally gets a kick toward the Appalachians Friday,
a few showers may linger in eastern IL. However, rising upper
level heights and an increasing southerly low level flow will
finally allow temperatures to climb toward seasonal levels Friday.
Upper level ridging is then expected to rapidly develop across our
region next weekend resulting in temperatures climbing well into
the 80s. The increasing low level warm advection will also mean
yet another chance of showers and thunderstorms with the warmer
conditions as our wet weather pattern the past month continues.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1250 PM CDT Sun May 17 2020

An active period with varying conditions can be expected at all of
the central and eastern IL TAF sites the next 18-24 hours with
afternoon convection, ceilings from LIFR to VFR and wind shifts.

Just before 18z a cold front extended from about KMLI to a bit
east of KUIN. A warm front was well to the north of the forecast
area, with much of central IL in the warm sector. Scattered
showers and isolated t-storms were present in the warm sector,
along with gusty south winds. As the cold front progresses
eastward through central IL this afternoon, thunderstorms will
become more widespread along and just ahead of the boundary.
Ceilings will generally be MVFR ahead of the front, although a dip
to IFR levels is expected in the thunderstorms.

The front is expected to reach eastern IL/I-57 corridor just
before 00z. After the frontal passage the wind will shift from the
west and slightly drier air could allow ceilings to rise to VFR
levels into early evening across parts of central IL. This will be
short lived though, as an upper level low - in central IA at 18z -
drops to the southeast into west central IL by daybreak. This will
spread IFR ceilings and scattered showers back into central
Illinois, which will persist through Monday morning.

&&

.ILX WATCHES/WARNINGS/ADVISORIES...
Flash Flood Watch through Monday morning for ILZ051.

Flash Flood Watch until 7 PM CDT this evening for ILZ038-042>046-
