.SHORT TERM...(This evening through Tuesday)

Issued at 324 PM CDT Mon Mar 20 2017

Cold front/wind shift line is just entering the northwestern
forecast area this afternoon. Ahead of this line, clouds cleared
much of northwest Minnesota and the Red River Valley allowing
temperatures to soar into the upper 40s/low 50s. The Devils Lake
basin remained under thicker cloud cover for most of the day, and
with the arrival of a northerly wind shift, temperatures have
remained a bit cooler out that way.

More cloud cover is moving back in to the area (mainly along and
south of Highway 2), and spreading from west to east. Models have
been having a hard time with the extent of cloud cover which will
likely have an impact on how far temperatures drop tonight. An
additional factor will be the increasing northerly winds along and
behind the front to 10-15 mph (gusts maybe 25-30 mph north)
overnight. Lastly, a compact upper wave (depicted nicely on water
vapor this afternoon) near the Saskatchewan/Manitoba border will
propagate southeastward and clip the far northeastern forecast
area. Some light snow showers (or at least flurries) aren`t out of
the question with this feature, even with somewhat limited
moisture in place, across mainly the Lake of the Woods area. Any
accumulation should be minor, if anything at all.

Canadian high pressure will build southward into the area on Tuesday
ushering in much colder air relative to Monday. Cool, northerly flow
will keep temperatures below the freezing mark once again, except
for maybe the far south along the South Dakota border.

.LONG TERM...(Tuesday night through Monday)

Issued at 324 PM CDT Mon Mar 20 2017

The forecast for this period starts off with cold high pressure
sliding southeast from southern MB into the Great Lakes region. An
upper ridge will move through the area on Wednesday...with southerly
winds increasing across the region. Warmer air then moves into the
area for Thursday, but so will some precipitation. Right now it
looks like it should be mainly rain Thursday and Thursday night. A
cold front will approach from the north on Friday, but there is some
uncertainty how far south this front will progress. After Friday
morning`s precipitation in the far southeast, conditions look dry
until Sunday night/Monday when chances for mainly rain return. After
a close to normal Wednesday, temperatures look to be generally above
average for this period.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)

Issued at 108 PM CDT Mon Mar 20 2017

VFR conditions expected throughout the period. Current forecasts
keep any ceilings south of the TAF sites. Westerly winds will
become more northerly throughout the period at 10-15 knots.
