Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
222 AM CDT Wed Apr 5 2023

.SHORT TERM...
Issued at 159 AM CDT Wed Apr 5 2023

Through Thursday...

The main focus in the short term remains on convective trends
through this afternoon, with the evolution of upstream activity a
bit unclear this morning.

Earlier strong-severe convection has--temporarily at least--
cleared our area. In its wake, a robust surface warm front is
moving northward and seems to have just about cleared our entire
forecast area. Strong southerly winds will continue to hold
temperatures pretty steady overnight, and some sporadic gusts to
30-40 mph will be possible, primarily well south of I-80 in the
vicinity of slightly steeper near-surface lapse rates.

While Lincoln and Davenport's evening soundings reveal strongly
capped environments to surface-based parcels, the persistent feed
of southerly winds pushing low to mid 60 degree dewpoints
northward will result in incrementally diminishing MLCIN through
the overnight hours, with further lifting/cooling of the based on
the lingering EML plume ahead of the surface low expected to
result in values lowering enough to support renewed development
and/or intensification of ongoing convection.

Currently, regional radar loops reveal outflow continues to push
ahead of the convective complex north of I-80 in eastern Iowa with
a persistent diminishing trend noted to updraft intensity. Increased
forcing may allow for additional storm development immediately
along and behind this feature as it drifts into our area after
about 4 AM. While cells may ultimately remain disorganized, they
will be entering an environment with increased MUCAPE with
eastward extent, so any supercells that are able to sustain
themselves will be capable of producing a few instances of large
hail and perhaps a severe wind gust. Think the tornado threat in
the immediate term should remain muted, although we've recently
seen some signs of increasing low- level rotation on the cell NW
of the Quad Cities.

Eyeing an additional area of convection farther south--currently
developing into western Missouri on the southeastern flanks of a
150 kt jet streak. Conceptually, this activity seems like the area
for us to watch for later this morning for the main severe
potential. Timing these features out, getting an arrival into
Livingston/Southern La Salle Counties around 600-630 AM, and
through our NW Indiana counties by 9-10 AM. Obviously, this is a
climatologically unfavorable time for severe weather in our area,
but this may be offset largely by the already only weakly-capped
environment and expected strong attendant linear forcing. Always
tough to figure out how these scenarios will play out, but see an
potential (given enough continued maturing of this SW cluster)
with the strongly-sheared parameter space for a severe threat,
particularly across the southeastern half if not 2/3rds of our
forecast area during rush hour. Surface winds ahead of this
complex look pretty veered (SWly) which will cut down on eSRH a
bit, although with 60 kts presence at 1 km, this may not matter
too much with 300+ m2/s2 values advertised by incoming guidance.
One wildcard will be whether outflow currently meandering
southeastward across central Missouri and also into NW Illinois
will get ahead of activity sufficiently to curtail surface-based
inflows. If this happens, the severe risk would likely be muted in
our area. However, given the recent trends noted on the lead
supercell. Any discrete/semi-discrete cells would also carry an
attendant large hail threat.

Activity looks to largely clear our forecast area by 10-11 AM. The
next question is whether additional activity sprouts on the actual
cold front which will lag this morning convection by a few hours.
It seems possible that things get overturned sufficiently that the
front will not convect as readily. At this time, the RAP is the
most aggressive firing additional (low-topped) storms on the
front, with better chances looking to occur more into Indiana
through mid-late afternoon.

Gusty non-thunderstorm will also develop today. An initial "pop"
immediately ahead of the cold front/departing convection appears
possible as mixing into the lingering 50-55 kt low-level jet
occurs. This will be followed by general 35-45 mph gusts through
the afternoon.

Quieter conditions expected into Thursday although gusty westerly
winds will continue. Deeper mixing within the drying airmass will
likely support afternoon RHs falling into the 25-35 percent range
which will support a slightly elevated fire danger within the
breezy post-frontal airmass.

.LONG TERM...
Issued at 222 AM CDT Wed Apr 5 2023

Thursday night through Tuesday...

Generally quiet weather until Sunday night/Monday when the models
had been showing a cold front moving across the area. Not much of
a front in the latest model runs and precip chances have decreased
for Sunday night. Best chance of precip now seems to be on Monday
as a weak wave moves across the area.

Temps warm back above normal by Saturday and then increase a few
degrees each day into next week when even the blended guidance is
in the upper 70s to near 80 Tuesday and Wednesday. Lake breezes,
southeast winds may keep the Lake Michigan shore cooler through
Sunday, but if southwesterly winds increase enough with the warmer
temps, they may extend all the way to the lake shore by midweek.

.AVIATION...
For the 06Z TAFs...

1229 AM...Primary forecast concerns include...

Chance of thunderstorms toward daybreak.
Chance of thunderstorms late morning/early afternoon.
Strong/gusty southerly winds this morning.
Strong/gusty westerly winds this afternoon.

Scattered thunderstorms extending from central IA into MO are
expected to continue moving east early this morning. Activity
across MO may become the primary area of thunderstorms to affect
the area toward daybreak though there still remains uncertainty
for coverage with this activity. Much of guidance shows this
morning activity as the main thunderstorm activity today, shifting
east during the mid/late morning. There is a chance for additional
thunderstorms along the cold front in the late morning into the
early afternoon. Confidence is low for thunderstorms during this
time period, which may end up being dry. Maintained tempo thunder
mention during this time period but changes can be expected.

Winds are slowly turning southerly at the terminals and will
slowly turn south/southwesterly by morning. Gusts through the
night will likely be in the mid 20kt range. Winds will shift
westerly behind the cold front this afternoon with gusts into the
mid 30kt range, with perhaps a few gusts in the upper 30kt range.
Winds will begin to diminish with sunset. cms
