Area Forecast Discussion
National Weather Service Grand Forks ND
1137 PM CDT Fri Mar 23 2018

Issued at 1137 PM CDT Fri Mar 23 2018

The back edge of the snow is moving eastward pretty quickly now,
but there should still be a window for some light snow in the Red
River Valley. Again, amounts in the Red River Valley will not be
all that much, but as temperatures fall overnight, roads will be
slippery in spots. The ND DOT travel information map shows the
worst road conditions west of the Red River Valley and north of
Interstate 94. The other thing that looks like it will occur is
some fog/freezing drizzle after the snow moves out, especially in
areas west of the Red River Valley. So although the snow may end,
problems may not.


.SHORT TERM...(This evening through Saturday)
Issued at 349 PM CDT Fri Mar 23 2018

Challenging situation continues with lower level dry air
continuing to win out. Decent radar returns have persisted across
the western and southern forecast area for several hours now but
obs, webcams, and public reports all have indicated very little
reaching the ground. Finally starting to see some reductions in
visibility in both observations and on webcams across the Devils
Lake basin and James River Valley. However, did cut down snow
amounts (and adjusted headlines accordingly) with nothing really
accumulating yet up to this point. Based on upstream obs and
current radar, expecting the far western forecast area (Canadian
border down through the Devils Lake basin and into the Valley City
area) to see the greatest impacts so have kept the Winter Storm
Warning going for these areas.

Conditions look to gradually improve from west to east Saturday.

.LONG TERM...(Saturday night through Friday)
Issued at 349 PM CDT Fri Mar 23 2018

The next round of wintry weather arrives on Saturday night.
Currently expecting that it will start as snow before
transitioning to rain during the day on Sunday. Some freezing rain
is possible Sunday morning with warmer 850 mb temperatures near
the freezing point. There will be yet another round of wintry
weather Sunday night into Monday night. This will also likely
contain a wintry mix of precipitation with temperatures near
freezing through the period.

There is potential for another system to move in later in the work
week but there is still disagreement between model guidance on
timing and location. The GFS, NAM, and CMC all agree though that
this will be a lower impact event.

Seasonable to slightly below normal temperatures are expected though
this period. Warmer temperatures are expected in the early part of
the work week with cooler temperatures expected later in the work


.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1137 PM CDT Fri Mar 23 2018

The steadier snow has about stopped now at KDVL, but some fog and
freezing drizzle may move in. Expect some steadier snow now for
KGFK and KFAR, which may last into the early morning hours. Little
effects will be felt at KTVF and KBJI. Hard to get a good feel for
ceilings, but models have been showing decreasing clouds on Friday
from the KBJI/KTVF areas trying to push westward. So better
conditions will remain on the MN side.


ND...Winter Weather Advisory until 7 AM CDT Saturday for NDZ006>008-
