.SHORT TERM...(Tonight through Monday Night)
Issued at 213 PM CDT Sun Oct 14 2018

Latest water vapor and RAP 500MB analysis show a long wave trough
carved out from the Northern Plains through the Desert Southwest.
Embedded shortwave trough currently ejecting out of the Central
Plains toward the Upper Mississippi and Great lakes regions. Radar
currently showing a band of frontogenetical induced mixed
rain/snow extending from central Upper MI through eastern NE. 3
inches of snowfall was reported at Oak Center as of noon but was
melting now. Some other areas across southeast MN picked up just shy
of an inch of snowfall. Look for this precipitation is to push
southeast of the area this evening as high pressure builds in from
the Plains. Then, plan on slow clearing of clouds from northwest to
southeast overnight with temperatures falling into the middle 20s to
near 30.

High pressure will be over the area Monday for partly to mostly
sunny skies. A cold day otherwise with temperatures only toping off
in the upper 30s to the middle 40s. Breezy west winds will add to
the chill.

Low pressure moving through southern Canada will push some mid-level
clouds into areas mainly north of I-94 Monday night. Otherwise, look
for lows in the upper 20s to the lower 30s.

.LONG TERM...(Tuesday night through Saturday)
Issued at 213 PM CDT Sun Oct 14 2018

A weak cold front drops through the area Tuesday as that low over
Canada pulls to the east. No precipitation is expected with this
frontal passage. Main impact will be a few mid-clouds and breezy
west winds in the 10 to 20 mph range. Look for highs in the middle
40s to the lower 50s.

After a dry/colder Wednesday, a milder/dry Thursday is expected as
warm air advection kicks in ahead of another low pushing through
Canada. Expect highs in the 50s.

A chance of rain enters the picture Friday into Saturday morning as
a cold front extending from that Canadian low drops through the
region.

A return to dry conditions for Sunday with highs in the middle 40s
to the lower 50s.
