.UPDATE...
The AVIATION Section has been updated below.

.SYNOPSIS...
Issued at 333 PM EDT Sat Mar 28 2020

Scattered severe thunderstorms will continue through the rest of
the day today and continue into the early overnight hours. Rain
will end by tomorrow morning with very windy conditions during the
day. Much of next week will be dry with small chances for rain
during the middle of the week as a couple of upper level
disturbances move through the area.

&&

.NEAR TERM /Tonight/...
Issued at 916 PM EDT Sat Mar 28 2020

Large area of rain/embedded thunderstorms currently spreading into
the area from the southwest, ahead of an upper level disturbance
moving through southern Illinois. This feature is expected to move
east of the local area around 290500Z, followed by the cold
frontal passage, roughly in the 290500Z-290900Z time frame. Short
term model data are not very bullish on convective development
along the actual front later tonight, possibly due to the lead
impulse stealing some of the energy.

Nevertheless, deep layer shear is expected to become very high
later tonight, as a 55 kt low level jet moves into the area,
coupled with the approach of a 95 kt mid level jet. A narrow area
of moderate instability exists over Illinois, ahead of the cold
front. As a result, conditional severe threat still looks rather
high later tonight, depending on how much convection can hold
together, closer to the frontal zone.

Will keep PoPs high until the frontal passage later tonight, and
then drop them off rapidly after that. Potential exists for some
wind gusts in the 30-35 kt range later tonight, if the low level
jet can mix down in places.

Previous discussion follows.

Active weather is expected for the rest of today and tonight as a
strong upper level low pressure system tracks across the Upper
Midwest and a surface cold front passes through central Indiana.
Severe weather will be ongoing during the early overnight hours
with the best chance for severe weather generally before midnight.
Very strong low level dynamics will be in place with abundant low
level shear and helicity. Instability continues to be marginal but
with such abundant dynamics, severe weather will be likely. Large
hail will be the primary threat with the potential for gusty winds
and tornadoes. With such strong dynamics, there is a potential for
significant and long tracking tornadoes. After midnight, the front
will be passing through and the threat for severe weather and rain
will diminish. Lows tonight will range from the upper 40s across
the northwest to the upper 50s in the southeast.

&&

.SHORT TERM /Sunday through Tuesday/...

Issued at 333 PM EDT Sat Mar 28 2020

The primary concern for the period is going to be the very strong
gradient winds during the day Sunday. In the aftermath of the
frontal passage, very strong pressure gradient forces and strong
winds aloft will bring advisory level winds in excess of 40 mph to
much of central Indiana. There are some concerns that the cloud
cover may inhibit winds mixing down to some degree, but there is
enough confidence that there will be efficient enough mixing to
bring winds in excess of 40kts. These winds will begin during the
morning hours and continue until sunset.

High pressure will briefly build Sunday night and Monday with dry
weather expected. Another upper level low pressure system will
track across the Tennessee Valley on Tuesday, but is currently not
expected to bring rain to the area except for possibly the
southern counties. If the low pressure changes track, higher POPs
may be needed in a later forecast package. Current thoughts are
the best chance for rain would be during the day Tuesday.

High temperatures are expected reach the mid 50s to low 60s
tomorrow and Monday and then the mid to upper 40s on Tuesday. Lows
will fall into the low 30s to low 40s Sunday and Monday nights.

&&

.LONG TERM /Tuesday Night through Saturday/...
Issued at 254 PM EDT Sat Mar 28 2020

Ensembles indicate the potential for a couple of systems to affect
the area during the extended, in a generally progressive flow.

The first trough is expected to be in the process of passing off
to the east of the local area Tuesday night. Will keep some chance
PoPs for rain for Tuesday night to cover any lingering activity
with this trough.

There may be a relative lull in the precipitation threat by
Wednesday and Thursday, as some upper ridging moves in for a time,
before the next trough moves into the western Great Lakes by next
Saturday. It appears from the ensembles that the best threat for
precipitation with this system will be in the Friday to Saturday
time frame.

&&

.AVIATION /Discussion for the 290300Z KIND TAF Update/...
Issued at 1021 PM EDT Sat Mar 28 2020

Organized convective activity currently affecting the KIND
terminal is expected to last for another hour or so, based on
radar.

Surface winds currently affected by convection, but should settle
into a 160-180 degrees range shortly. Some brief surface gusts
near 30 kts possible in the immediate wake of the convection.

Previous discussion follows.

Expecting convective activity to increase in the vicinity of the
terminals after 290100Z-290200Z, as an upper disturbance currently
moving through southeast Missouri, begins affecting the local
area. Brief IFR visibility restrictions and gusty shifting winds
in and near the heavier cells. Appears the bulk of the convective
activity will move off to the northeast of the terminals around
290500Z, but the threat for widely scattered activity may linger a
couple of hours longer until frontal passage during the early
morning hours of Sunday.

Otherwise, areas of MVFR ceilings 015-030 expected along and ahead
of the front. Will probably see these ceilings scatter out for a
period during the pre dawn hours of Sunday in the post frontal
zone, but may start filling back in from the west towards sunrise
Sunday.

Outside of convective activity, surface winds generally 190-210
degrees this evening will veer around to 220-240 degrees after
frontal passage. Occasional surface gusts 18-22 kts are also
possible.

Surface winds should veer around to a southerly direction over the
next few hours at KLAF, as a warm front lifts north.
