Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
146 PM CST Tue Jan 23 2018

.SHORT TERM...(This evening through Wednesday)
Issued at 145 PM CST Tue Jan 23 2018

The main short term concern is clouds trends.

Band of low clouds remains over western MN this afternoon, ahead
of a developing warm front over the Dakotas. This area of clouds
is expected to move and develop eastward tonight brining mostly
cloudy conditions to the region. There may a bit of light fog as
well as it moves over the state. Other than that, temperatures
will drop off into the teens most areas with some single digits to
the east before cloud envelop that region. Readings Wednesday may
be tempered somewhat and will be dependent on cloud and snow

.LONG TERM...(Wednesday night through Tuesday)
Issued at 145 PM CST Tue Jan 23 2018

The main long term trends continue to indicate a warming trend
into the weekend. Then cold front progged over the area cooling
the region into early next week.

The flow pattern is becoming more progressive with a series of
frontal passages. We should warm as heights aloft rise for the
remainder of the week, with readings warming into the 40s for much
of the area Friday. It appears the initial cold front(more Pacific
origin) moves through the area Saturday and could bring in a
small chance of snow Saturday night/Sunday. The main issue will be
for much cooler air and brisk northwest winds for Sunday as the
upper trough moves over the area into Monday.

Following that, the faster west/east flow continues with a
warming trend indicated again into midweek.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1055 AM CST Tue Jan 23 2018

MVFR cigs have eroded across central area. May still keep cigs
going at KEAU this afternoon, perhaps clearing some into the
evening. KAXN-KRWF on the edge of the western cloud bank. Expect
this area to begin to shift east during the afternoon and cigs
lowering to IFR and perhaps some Fog. This may work east
overnight into western WI early Wed morning, We will mention IFR
to the west and north and keep lower end of MVFR cigs to the east
and south for now. Light n-nw wind becoming light s-sw into

KMSP...VFR trend through the afternoon with perhaps some MVFR
cigs moving in this evening. Still a chance of IFR later tonight.

Wednesday afternoon.

Thu...Chc MVFR/IFR cigs. Winds SE 5-10 kts.
