.UPDATE...No changes to forecast at this time.

.AVIATION(12Z TAFS)...Low pressure continuing to pull away from
area today with cold/dry advection taking hold. Plenty of MVFR and
some IFR stratus hanging tough. Some light rain possible in the
southeast corner this morning. All in all cloud cover likely to
linger through tonight with northwest winds trending more northerly
heading into tonight and becoming gusty, especially in the eastern
portions of the area.

.PREV DISCUSSION... (Issued 346 AM CDT Thu Apr 18 2019)

SHORT TERM...

Tonight and Tonight - Confidence...Medium
Surface low pulling to our east with cold/dry air advection
taking hold with the wind shift to the west and eventually northwest.
Plenty of cloud cover wrapping in behind the departed low. Mid level
trough axis and low level thermal trough to amplify across the area.
Some light rain may clip the southeast this morning from wave ridging
northeast along the front. With the clouds and cold advection will
probably steer closer to the cooler guidance after starting out with
some milder temps. Cloud cover and steady winds will likely keep temps
from dropping off much overnight.

LONG TERM...

Friday and Saturday...Forecast confidence is high:

Clouds will gradually clear west to east on Friday as high
pressure builds in from the west. Highs should recover to around
normal in the western forecast area. Clouds will hang on longer in
the east and there will also be an onshore component to the
winds, so temps will be cooler than in the west. Northerly winds
will be breezy between the departing low and approaching high.

The high will be weakening on Saturday as it slides overhead.
There should still be enough of an influence of the high for a
pleasant day, with temps a bit above normal (except for near the
lake) and plenty of sunshine.

Sunday through Wednesday...Forecast confidence is low to medium:

The forecast for the first half of next week remains a bit
uncertain. A weak trough and associated front will approach
Sunday, with a few showers and storms possible when it does move
through later Sunday or Monday. Kept the forecast dry Sunday, as
only the GFS is quick enough for some precip on Sunday. Looks like
the front may stall just south of Wisconsin, with more
shower chances at times into mid-week. A lot of questions with the
timing of the front, how far south it goes, timing of waves, and
resultant temp and precip chances. It does mild on Sunday as a
consensus of models keeps southerly flow ahead of the front for a
good portion of the day. Could see temps approach or hit 70
across much of the forecast area. Kept temps near normal beyond
that, though not a lot of confidence in this forecast.

AVIATION(09Z TAFS)...Low pressure continuing to pull away from
area today with cold/dry advection taking hold. Plenty of MVFR and
some IFR stratus hanging tough. Some light rain possible in the
southeast corner this morning. All in all cloud cover likely to
linger through tonight with northwest winds trending more
northerly heading into tonight.

MARINE...Cold advection kicks in this morning with low pressure
shifting east from northern Lake Michigan. Winds will be shifting
to the north/northwest. Current small craft expires at 12z. Based
on expected winds tonight into Friday feel we will eventually need
a ramp up small craft from around 04z-09z and then decided to add
the nearshore zones to the Gale watch that runs from 09z through
00z Saturday.
