Area Forecast Discussion...UPDATED
National Weather Service Twin Cities/Chanhassen MN
538 AM CST Tue Jan 23 2018

.SHORT TERM...(Today and tonight)
Issued at 404 AM CST Tue Jan 23 2018

A much quieter day today with stratus dissipating across much of
the area due to the subsidence behind the departing winter storm.
Should see a fair amount of sun this morning before clouds
increase some again later today into tonight. Highs will be near
normal in the 20s.

.LONG TERM...(Wednesday through Monday)
Issued at 404 AM CST Tue Jan 23 2018

Overall a quiet long term period ahead with no significant chances
of precipitation in the foreseeable future, and temperatures running
above normal for late January.

Later this week, an upper level ridge will begin pushing into our
area Wednesday night as a trough over the Pacific reaches the west
coast, enhancing the downstream ridge and pushing it east. A clipper
system will result for southern Canada as we head into Thursday
night and Friday, bringing warm southwesterly flow to our area.
There are still some timing differences with the frontal passage
Friday as the surface low in Canada translates east.  This will be a
dry fropa for us, but the timing could really affect how warm we get
on Friday ahead of the front.  For now, kept a blended approach in
the forecast for lower 40s due to the timing differences.  For the
areas that just received significant snowfall, trended the highs
downward from the previous run given the obvious influence of the
new snowpack.  Would not be surprised for the forecast to continue to
get cooler for the snow covered portion of our forecast area.

Temperatures will cool through the weekend behind the aforementioned
clipper, but just drop to near normal for a day or two.  The
progressive pattern lifts the jet back north early next week, with
no significant systems anywhere nearby expected at this time.


.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 538 AM CST Tue Jan 23 2018

Clouds had been rapidly clearing overnight, but they are beginning
to close in from the east again. Expecting the clearing area to
fill in this morning with MVFR cigs likely through the rest of the
period. Northwest winds 10 kts will become light west or
southwest tonight.

KMSP...It looks like the clouds have returned and should remain
for much of the period. It`s possible some rise in cigs could
occur this afternoon, but will likely lower again tonight.

Wed...MVFR/IFR cigs. Winds SW 5 kts.
Thu...Chc MVFR/IFR cigs. Winds SE 5-10 kts.
Fri...Mainly VFR. Winds S-SW 5-15 kts.
