.SHORT TERM...(This evening through Wednesday)
Issued at 310 PM CDT Tue Apr 24 2018

North winds will decrease this evening and there will be a period
of light winds over night as a SFC high pressure ridge crosses the
FA. With the clear skies and light winds temps are expected to
drop efficiently into the 30s and a few upper 20s across eastern
areas of the FA for overnight lows. Return flow increases west to
east during the early morning with efficient mixing developing
by noon. BUFKIT soundings indicate mixing around 30kts up to
around 850mb across the Devils Lake basin by midday. Indications
are that the northern valley and the Devils Lake basin will be
just under the criteria for advisory headlines. But still a breezy
day with temperatures back into the 60s for the most of the FA.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 310 PM CDT Tue Apr 24 2018

Rain chances move through Wednesday night into early Thursday as a
cold front pushes through from southern Manitoba toward eastern
Minnesota. Behind the front, breezy north winds will develop for
Thursday with gusts to 35 mph. The best chances of rain will be for
areas along and north of U.S. Highway 2. Thursday will be cooler,
with cold air advection and exiting cloud cover preventing stronger
daytime heating. Highs Thursday are expected to only reach the 50s.

Dry and quiet weather returns for the end of the week and into the
weekend, as an upper ridge builds in. The weekend will bring a warm
up, with high temperatures pushing into the 70s and perhaps even
near 80 in the southern valley on Sunday. Looking into early next
week, a more active weather pattern is expected as the ridge
departs.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1139 PM CDT Tue Apr 24 2018

Light winds overnight will become southwest by Wednesday morning,
then increase quite a bit through the day. The strongest winds
should affect KDVL/KGFK/KTVF, then should fall again around
sunset. However, any fall will be short lived, as winds switch to
the north and increase again late Wednesday evening. It is beyond
the TAF period, but the post midnight Wednesday night into
Thursday morning looks to remain quite gusty.

.HYDROLOGY...
Issued at 310 PM CDT Tue Apr 24 2018

Little additional water expected to enter the river system as there
is little to no snow left to melt and little precipitation is
expected over the next five days. The main impact will be the flood
wave moving north along the Red River Valley with rivers cresting or
falling from Oslo and to the south. The Red River at Drayton and
Pembina are still rising as the water moves north into Canada. The
Goose at Hillsboro is currently at moderate and falling with
flooding expected to end Thursday. Farther north the Red at Grand
Forks is near its crest with flooding expected to end early next
week. The Red at Oslo is nearing its crest and flooding there will
continue into next week.
