Area Forecast Discussion
National Weather Service Grand Forks ND
244 PM CDT Sun Mar 25 2018

.SHORT TERM...(This evening through Monday)
Issued at 242 PM CDT Sun Mar 25 2018

WAA is overrunning our CWA aloft with southerly flow ahead of a
trough passing through southern Canada (currently entering western
Manitoba). An axis of positive frontogensis is bisecting our CWA
from the southwest to the northeast and in the expected region to
the west-northwest of this we have several bands of moderate snow
tracking through the Red River Valley. Snowfall rates have exceeded
1.0" per hour at times, and visibility has dropped to 1/4 or less
for brief periods during the heavier snow. Short range guidance has
a decent handle on the track of ongoing precipitation and favors
this winding down as subsidence/dry air working into the region from
the northwest behind the shortwave trough. Current advisory is set
to expire at 03Z, and this seems like good timing. It appears some
locations may exceed 6" (warning criteria), however this should be
very localized.

The next round of wintry weather late tonight and Monday will be
associated with a shortwave expected to move from the Central
Rockies across South Dakota. A negatively tilted 850 MB/700 MB
trough is shown to briefly close of st it moves towards the
southeastern part of our CWA. This may allow for the development of
a deformation zone and possible banding from I-94 and southeast.
Ahead of this system there is the potential for a dry slot to linger
and delay introduction of ice to the atmospheric column. This raises
the possibility of freezing drizzle or freezing rain in the 09-14Z
period before a full transition to snow takes place. Ultimately we
may need to consider an advisory for our south for icing and our
southeast for moderate snow. With ongoing hazards in place we are
holding off for now, and monitoring trends.

.LONG TERM...(Monday night through Sunday)
Issued at 242 PM CDT Sun Mar 25 2018

Mon night through Sun...

The active weather pattern will continue from the middle of the
upcoming week through the first part of the weekend.

Lingering pcpn Mon eve will come to an end over northwest MN,
perhaps as a mix of snow and freezing RA/DZ. Tue will see quiet and
mild weather as a surface high resides over the northern Plains.
Temps near average for this time of year will prevail, with highs
from the upper 30s to low 40s.

A clipper low moving across southern Canada will bring additional
pcpn chances along a cold front for Wednesday. The ECMWF keeps most
action over the northern part of the forecast area while the GFS is
more generous with the placement. All guidance agrees on a column of
above zero temps aloft, leading to a possible period of sleet
creating some morning commute impacts. The rest of the day will
feature snow, possibly changing to rain for a time during the
afternoon as the boundary layer warms.

Quiet weather will follow for Thursday but the clipper will usher in
some colder temps, persisting through the weekend. Ensemble plumes
back up operational guidance, pegging the region with an un-
springlike temp regime of about 15 degrees below average. On top of
that additional light snow chances will be possible Friday through
Saturday.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1242 PM CDT Sun Mar 25 2018

Moderate to heavy snow band is currently impacting KFGF, and this
may begin to transition towards KTVF and KFAR, though impacts
should not be as great. This should weaken and eventually
transition out of NE ND and NW MN by 03Z. We will then be
monitoring another system than could bring a wintry mix to
locations along and south of I-94. Confidence is not as high on
that system to lower conditions too far with this TAF issuance,
but it will need to be monitored for the possibility of freezing
rain and reduced vis.
