Synopsis
Issued at 424 am edt Thu sep 20 2018
one more hot day will be in store for many areas as highs reach
the upper 80s to lower 90s. A chance for a shower or storm will
exist mainly along and north of the toll road into this afternoon.

There will be a chance of showers and thunderstorms Friday afternoon.

Cooler temperatures will filter in behind a cold front with highs
only into the 60s on Saturday, then mainly in the 70s next week.

Short term (today and tonight)
issued at 424 am edt Thu sep 20 2018
low confidence forecast regarding impacts of upstream convection
and precip chances into this afternoon as well as temperatures.

Elevated frontal boundary has been active for several hours now
from NE nebraska into southern wisconsin. Recently developed
showers and storms were also being seen across portions of west
central lower michigan. Activity should remain north of the area
until possibly closer to the 12z as outflow boundary pushes south
and allows for at least a chance for a few showers or storms. Have
attempted to capture this as best as possible with pops expanding
southward for a period this afternoon as warm sector becomes
rather unstable with MLCAPE 1000-2000 j kg. Best shear will
reside well north of the area resulting in more pulsy storms that
are able to develop with SPC marginal risk being pushed north of
the forecast area.

Cloud cover today will be key in determining final afternoon
highs with potential for locations in the southwest to get quite
warm once again. Higher dewpoints may limit overall potential for
mid 90s but can't fully rule out. Kept with previous forecast with
coolest readings north and east where clouds may linger longer.

Dry forecast this evening and most, if not all of tonight as line
of showers and thunderstorms advertised to develop west of us
along the cold front and move east. Most models weaken this
convection as it outruns best forcing but left some low pops in
w NW areas towards morning. Winds will increase as low level jet
ramps up to over 50 kts and at least some mixing of stronger winds
occurs.

Long term (Friday through Wednesday)
issued at 424 am edt Thu sep 20 2018
outflow boundary pre frontal trough from overnight convection will
be the main focus for best convection chances. Hi res models
generally split on either this boundary re-firing in far SE areas
or possibly remaining somewhat active with showers during the
morning that eventually intensify. Instability and increasing
shear warrant a marginal risk of severe for at least SE third if
not a bit further nw. SPC day 2 outlook expanded marginal NW into
se 2 3rd or so of the area. May be somewhat overdone but with some
models hinting at storms further NW due to possible slower
movement of front can't argue.

Precip should be clear of the area by Friday night with much
cooler air funneling in. Highs in the 60s will dominate Saturday
with only some moderation back towards normal temps into mid week
as stronger trough digs into the plains and works east with
increasing chances for showers and possibly some storms starting
as early as Monday afternoon but especially tues afternoon and
evening when timing of energy and peak heating all combine. Colder
air will return again behind the front.

Aviation (for the 06z tafs through 06z Thursday night)
issued at 115 am edt Thu sep 20 2018
some increasing mid and high cloud expected through the remainder
of the overnight as convective complex entering southern
wisconsin bypasses northern indiana to the north. Terminals remain
to the north of stalled frontal boundary this morning, but
diurnal mixing will allow rapid northward mixing of this front
into southern lower michigan today. Gradient should remain strong
enough this morning to prevent fog from becoming a big concern,
although cannot discount some MVFR vsbys at either terminal for a
time between 10z and 14z. Relatively unstable conditions to
develop this afternoon, but all mid upper level forcing of
significance will remain to the north. Lack of forcing combined
with rapid northward retreat of warm frontal zone continues to
argue for omitting any precip mention with the 06z tafs. Warm
sector south-southwest gradient to strengthen today with some
gusts to around 20 knots possible at ksbn this afternoon. Strong
inversion decoupling this evening should set the stage for
favorable llws criteria after 06z Friday morning, and this will be
addressed in more detail with the 12z TAF issuance.
