.SHORT TERM...(Tonight through Tuesday Night)
Issued at 155 PM CDT Mon Oct 15 2018

Deep/cold cyclonic flow starting to exit east of the area with
surface high pressure building in from the Plains. Skies varied from
mostly cloudy east of the Mississippi River to mostly sunny west of
the River. Temperatures across the area this afternoon were in the
30s to lower 40s with brisk west winds adding to the chill.

High pressure drifts east across the area tonight as low pressure
moves across southern Canada. This will set up breezy southwest
winds overnight with scattered altocumulus from time to time after
midnight. Overnight lows are expected to bottom out in the upper 20s
to the lower 30s with temperatures steadying out or slowly climbing
after midnight.

A cold front swings through the area by mid-Tuesday morning with
brisk westerly winds setting up. Scattered cumulus also expected to
develop during the day given cold air advection/cyclonic flow aloft.
Otherwise, plan on highs in the middle 40s to the middle 50s.

Clearing skies expected Tuesday night as high pressure builds in
with overnight lows in the upper 20s to the lower 30s.

.LONG TERM...(Wednesday through Monday)
Issued at 155 PM CDT Mon Oct 15 2018

Wednesday and Thursday look dry/mostly sunny with highs Wednesday in
the 40s, warming into the 50s Thursday.

A cold front rolls through the region Friday for a chance of rain.
Otherwise, temperatures look to be right around normal with highs
topping off in the middle 50s to near 60.

A secondary cold front drops into the area Saturday/Saturday night
for a chance of rain or a rain/snow mix. Look for highs Saturday in
the 40s and lows saturday night in the 20s/lower 30s.

40s/lower 50s Monday.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 626 PM CDT Mon Oct 15 2018

Blustery surface winds from the southwest will impact TAF sites
overnight and Tuesday morning. Potential exists for low level
wind shear overnight as strong west winds above the boundary layer
increase to 40-45 kts. Midday Tuesday, the cold front now
entering northern Minnesota will reach southeastern MN, bringing a
wind shift to the northwest. Otherwise, VFR conditions will
prevail through the TAF period.
