.SHORT TERM...(This evening through Wednesday)
Issued at 317 PM CST Tue Jan 24 2017

Main 500 mb short wave will move across central Iowa tonight
accompnied by sfc low. Snow associated with this system just north
of the sfc low in strong mid level deformation zone that will be
near the iowa/minnesota border. The light snow that was over parts
of southern ND has mostly ended, except for a bit of light snow
around from Aberdeen up to south of Jamestown where a couple of
inches did occur. Snow has dried up over our fcst area in far se
ND and wcntrl MN. For this upcoming night into Wednesday cloudy
skies. Did keep idea of low pops for spotty light snow/flurries
spreading in overnight into wednesday as 500 mb trough moves over
the area. Not expecting much at all with mostly trace amounts.
Temperatures will not change much.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 317 PM CST Tue Jan 24 2017

Fairly quiet through the end of the work week and into the weekend
across the forecast area. The period begins with the region between
surface low pressure off towards the Great Lakes and a broad area of
high pressure building into the western CONUS. As the low moves off
towards New England and beyond, the area will be under
north/northwest flow aloft for the majority of the period. A few
week waves look to pass through the upper flow but nothing major
with just chances here and there for some light snow showers or
perhaps even just flurries.

Chances increase for the possibility of at least some accumulating
snow late in the period as we head into the new work week. Both the
GFS and ECWMF depict a relatively stronger upper wave/Alberta
clipper quickly moving through but plenty of disagreement remains on
timing and strength.

No majorly strong cold pushes expected with temperatures remaining
around or above normal values.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 218 PM CST Tue Jan 24 2017

IFR ceilings overnight. Winds will be north to northwest at 5 to
10 kts.
