Synopsis
Issued at 418 am edt Fri may 24 2019
a warm front will move through the region today and tonight,
bringing chances for showers and thunderstorms back to the area
into the upcoming holiday weekend. Heavy rain and at least a
chance for strong to severe thunderstorms will exist through
Sunday. Temperatures will return to more seasonable levels by
Saturday before dropping again Sunday and Monday.

Short term (today and tonight)
issued at 418 am edt Fri may 24 2019
a couple of boundaries to focus on this morning, the first being
initial elevated surge of warmer air and increasing moisture
currently edging into the SW part of the area (upr 40 dewpts far ne
to upper 50s sw) and main surface warm front roughly from burlington
ia to decatur il and south of indy. Hi res models to some extent or
another have indicated development of widely scattered showers and
storms along the main warm front, which has been taking place over
the last couple of hours. Lighting has been confined mainly to
western il closer to stronger low level jet. That being said, vads
at 850 mb do show LLJ increasing to roughly 35 kts in association
with the warm front, resulting in a steady increase in speed and
activity over the next several hours. Challenges linger in the 12-
18z Fri window as to how far northeast this activity makes it and if
additional convection to the west edges in this morning to western
areas. Low confidence on how this unfolds so have kept slgt chc to
chc pops in mainly SW areas this morning, trending dry by afternoon
as warm front should surge far enough north to bring any precip to
an end. Temperatures will vary greatly ne-sw depending how fast the
front moves north, final resting place and amount of cloud cover
through the day, but 10 to 15 degree differences in temps will
likely occur today with highs into the 80s SW areas and possibly
upper 60s to near 70 ne.

Focus then shifts to development of showers and thunderstorms off to
the west with upper level ridging keeping main axis of precip
tonight across mainly NW half of the area. SPC has expanded the
slight risk for severe tonight from kankakee to plymouth to sturgis
with marginal risk for most of the remaining area (save far se).

Think this eastern extent may be overdone given increasing heights
aloft keeping main focus nw. Main risk overnight would be hail and
damaging winds along with heavy rain (spc edging slight risk for
excessive rainfall into far NW areas). A warm and muggy night will
be felt across the entire area with lows in the mid 60s and similar
dewpoints.

Long term (Saturday through Thursday)
issued at 418 am edt Fri may 24 2019
models vary on handling of convection expected to develop Friday
night and it's impacts on the forecast area Sat morning as warm
front will be north of the area with mid to upper 60 dewpoints in
place. If heating can take place during the day, threat for
showers and storms will increase by Sat afternoon with concerns
for severe weather in play, especially if any remnant
boundaries mcvs move in. SPC has maintained marginal risk in
western half and slight risk of svr eastern half focused mainly
sat afternoon eve. Damaging winds would seem to be the greatest
threat, but hail isol tornado would also pose a threat given
increasing low level jet and interactions with boundaries that may
exist. Lull will probably take place by Sat evening before next
round setup late Sat night into Sunday as cold front looks to move
in and force everything back south of the area for Sunday night
into Tuesday. Have maintained high chc to likely pops Sunday to
address this with chance for severe storms still existing until
the front exists.

Challenge then shifts to how far south the front will make it as
additional waves move along it before returning back north again
Tuesday into weds in response to much more substantial upper low
over nebraska or iowa by 12z weds. Strong storms could once again
become a concern with this system, but too much model variance to
focus on it a lot at this point.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1248 pm edt Fri may 24 2019
dryVFR conditions and east-southeast winds near 10 knots are
expected to persist this afternoon. A warm front, now draped west
to east across central il in, will lift north into northern
indiana this evening into Saturday morning. Interaction of this
feature with incoming convection from northern il will bring
increasing chances for a few rounds of showers storms to ksbn
this evening into the early overnight. Much lesser chances at
kfwa (hence the dry forecast), though cannot rule out convection
briefly sneaking into this area later tonight. Heavy rain and a
low threat for severe storms with this activity, especially at
ksbn this evening.
