Area Forecast Discussion
National Weather Service Grand Forks ND
703 PM CDT Fri Apr 28 2017

.SHORT TERM...(This evening through Saturday)
Issued at 250 PM CDT Fri Apr 28 2017

Quiet period ahead through the short term. Surface high pressure
will build into the region and hold through Saturday. Diminishing
winds and clear skies tonight will allow temperatures to drop back
into the 20s. Full solar expected again tomorrow and with modest
warm advection in the afternoon 50s should be more widespread
across the region.

.LONG TERM...(Saturday night through Friday)
Issued at 250 PM CDT Fri Apr 28 2017

The extended period starts with a split flow upper level pattern...
with the northern stream north of the international border and the
southern stream over the southern plains. Surface high pressure
remains in control before retreating east on Sunday ahead of the
next system.

Models are in reasonable agreement for timing and movement of the
next system to affect the region late Sunday night through early
Tuesday morning. There is some uncertainty to the track so the main
challenge will be the placement of the surface well as
temperatures at the surface and aloft affecting the type and amount
of precipitation. At this time...a small pocket of cooler air is
expected to be mainly in the southeastern portion of the forecast
area and some snow can be expected to mix with the rain. For
now...looking at an inch or two of snow in the coldest air and the
greatest precipitation amounts near and east of the Red River.

After the system tracks to the east late Tuesday...expect the upper
level ridge to rebound a bit over the area. By the end of the
period...will see more ridge amplification over the Rockies and a
return to much warmer temperatures. Otherwise...there will be
chances for light precipitation as a series of disturbances cross
the region. &&

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1234 PM CDT Fri Apr 28 2017

VFR conditions expected through the period with no cigs


.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 659 PM CDT Fri Apr 28 2017

VFR/clear skies tonight with northerly winds continuing ahead of
a ridge axis that will slide over the valley in the 06Z to 12Z
timeframe...allowing winds to become light prior to shifting
southerly during the morning hours Saturday. Winds will begin to
shift northeasterly by mid-afternoon across the southern valley
and west central MN as a low pressure system strengthens over the
central plains. This SE shift will most likely impact winds at
FAR/BJI while winds further north will remain southerly.
