Area Forecast Discussion
National Weather Service Grand Forks ND
641 PM CDT Mon Apr 23 2018

.UPDATE...
Issued at 641 PM CDT Mon Apr 23 2018

Not looking like any precipitation will reach the FA until
possibly after midnight, if at all. Went ahead and removed any
mention of rain this evening, and will see how things look by
later this evening.

&&

.SHORT TERM...(This evening through Tuesday)
Issued at 257 PM CDT Mon Apr 23 2018

Main weather impact through Tuesday will be light rain moving
through southeast ND and west central MN tonight. An upper trough
swings through in northwest flow aloft from western ND into SD
tonight into Tuesday. Drier northerly low level flow behind an
exiting surface trough and weaker synoptic lift will keep amounts
light, generally under a tenth of an inch of liquid. More noteworthy
lower level frontogenetical forcing does push through southeast ND
late tonight into early Tuesday morning, yielding the best chances
of rain.

Rain chances exit southward from the southern Red River Valley
Tuesday morning, with cloud cover lingering in the I-94 and
southward corridor into the late morning. Cold air advection and a
north breeze will make for a chillier day Tuesday, with highs only
reaching the 50s.

.LONG TERM...(Tuesday night through Monday)
Issued at 257 PM CDT Mon Apr 23 2018

South to southwesterly winds will pick up during the day on
Wednesday especially over northeast ND as a surface high gradually
shifts south into the central Plains and a surface trough associated
with a Canadian low begins to move into the region. Afternoon
relative humidity values are likely to drop into the 20s with the
risk of near critical fire weather conditions developing across
northeastern North Dakota.

Rain chances increase Wednesday night and into Thursday morning as
the trough/weak cold front pushes to the southeast. While precip is
expected to be scattered, northwestern MN will see the best chance
for any measurable rain. Same wind speeds expected Thu, this time
out of the north northwest. This will be accompanied by a push of
cooler air into the region, keeping temperatures in the low to mid
50s across the area. Warm, dry and calm weather returns for Friday
and into the weekend with temperatures starting in the 60s and
rising by about 5 degrees by Sun.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 641 PM CDT Mon Apr 23 2018

May see some mid level ceilings at KDVL or KFAR tonight, but
still well in the VFR category. Steady north winds overnight may
pick up a little by mid Tuesday morning.

&&

.HYDROLOGY...
Issued at 257 PM CDT Mon Apr 23 2018

Moderate flooding continues for the Red River at Oslo and the Snake
River at Alvarado. Log jamming vicinity of Hillsboro has caused a
spike up to moderate flood stage there, a situation expected to last
another day or two. Minor flooding continues or is anticipated along
the mainstem Red from Pembina south through Halstad except for the
moderate at Oslo.

Upcoming precipitation chances Tuesday and Thursday this week do not
show significant QPF signals and so are not expected to contribute
to river rise during the upcoming week.
