Area Forecast Discussion
National Weather Service Lincoln IL
907 PM CDT Thu May 18 2017

.UPDATE...
Issued at 905 PM CDT Thu May 18 2017

A couple of narrow bands of convection have lingered in far
eastern Illinois this evening, in the vicinity of a stalled
frontal boundary. There has been a general weakening trend over
the last couple of hours. Those storms should dissipate over the
next hour or so, with dry conditions for several hours and
possibly much of the rest of the night. The HRRR is indicating
some redevelopment near the front by 09z, mainly between I-70 and
I-72. A stronger wave of storms is projected to arrive from the
west toward 12z, with a few of those storms possibly strong to
severe. Bulk shear and low level helicity north of the warm front
appear sufficient for a few strong updrafts, with some strong
downburst winds possible as the line advances to the ENE after
sunrise tomorrow morning.

Have adjusted the PoP, Weather and Sky grids down in coverage
over the next 3-5 hours, with gradual increasing PoPs from west to
east late tonight.

A wide range of temps will exist across central Illinois for low
temps, due to the presence of the front. Lows will remain in the
low to mid 60s south of the front, with low 50s from Galesburg to
Lacon and mid-upper 50s in between.

Updated forecast info is already available.

&&

.SHORT TERM...(This evening through Friday)
ISSUED AT 300 PM CDT Thu May 18 2017

Showers and a few storms beginning to increase again across the
Ohio Valley this afternoon, back into southeast Missouri. Most of
the forecast area only seeing scattered clouds at the moment, with
a cold front edging into the northwest part of the CWA.
Temperatures have reached the mid-upper 80s over a good part of
the CWA except northwest of the Illinois River near the front,
where Galesburg was still holding in the upper 70s.

The front will be settling to around the I-72 corridor by mid to
late evening and I-70 overnight, with little movement due to the
near parallel flow aloft. Most of the short-range models maintain
some isolated showers or storms south of it through the evening.
The main threat of rain will be spreading in from the southwest
later in the night, as the large upper low over Utah and Colorado
digs southward and sends energy northeast out of the Texas
panhandle.

.LONG TERM...(Friday night through Thursday)
ISSUED AT 300 PM CDT Thu May 18 2017

The front doesn't make a lot of northward progress during the day
on Friday, but will surge northward Friday night as a shortwave
continues to push northeast. A rather large temperature gradient
can be expected, with highs ranging from the 60s from Havana-
Bloomington northward to around 80 degrees south of I-70. Plenty
of CAPE will be available south of the front, generally at least
2000 J/kg with even higher numbers indicated by the NAM, although
this will not be in an area of favorable shear. This should be
enough for some strong to severe storms, primarily over areas from
about I-72 southward.

Some tapering of the rain is expected during the evening, before
another widespread rainfall accompanies the approach of the
surface low as the upper system moves into the Plains. This will
usher in an extended period of precipitable water values of around
1.5 inches, which will persist until the low lifts northwest of
Illinois Saturday evening. A fairly widespread 1-2 inches of rain
appears likely over the forecast area, with some heavier amounts
in the stronger storms.

Once this system exits early Sunday, an extended period of cooler
conditions is expected for the upcoming week. As the upper low
moves north of the Great Lakes, a lobe of energy will drop
southward and form a deep trough over the Plains, slowly pushing
eastward across the Mississippi valley in the Tuesday night to
Wednesday time frame. Some model differences in the longer range
with this feature, with the ECMWF slower and further south as an
upper low cuts off. However, the precipitation that occurs should
mainly be periodic showers, with thunder chances fairly small.

&&

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 703 PM CDT Thu May 18 2017

Ongoing convection associated with a stalled frontal boundary
are expected to remain clear of the TAF sites for much of the
first 12 hours of this TAF period. A wave of storms is projected
to arrive near PIA and SPI between 11z-13z. The line of storms
will progress eastward across the area tomorrow morning, but with
scattered storms possible through mid-day. There should be a break
in the rain/storms for at least the first half of the afternoon,
before another line of storms progresses eastward across central
IL starting near the end of this TAF period.

Forecast soundings are showing a stratus deck developing after the
line of storms moves through tomorrow morning, with low MVFR and
IFR conditions expected. Conditions should improve to MVFR
tomorrow afternoon, with VFR conditions possible at times.
