Area Forecast Discussion
National Weather Service Grand Forks ND
947 PM CDT Tue Jun 5 2018

.UPDATE...
Issued at 947 PM CDT Tue Jun 5 2018

Elevated showers so far across our northwestern CWA, but there is
a narrow axis of instability extending between the warm/stationary
front just east of the Red River and the cold front beginning to
move into our western counties. MLCAPE values still around 1500
J/kg and there is plenty of deep layer bulk shear near 50 kts.
Thus, a watch in eastern ND. Progression of the cold front may
limit severe on the northern edge of the watch, but with the
instability axis still there can't rule out the severe potential.
Short range models are in pretty decent agreement on activity
ramping up during the next few hours across the southeastern CWA
into the Red River Valley, so adjusted POPs to fit current CAM
trends.

&&

.SHORT TERM...(This evening through Wednesday)
Issued at 306 PM CDT Tue Jun 5 2018

Big gradient in temperatures this afternoon, with mid 60s around
the Lake of the Woods to mid 80s near Gwinner North Dakota.
Surface moisture return is still pretty meager across most of the
FA, with mid 40 dew points around the Lake of the Woods. However,
they are higher to the west, where they are in the upper 50s from
Devils Lake to Gwinner. Not too much happening right now, there
are some elevated echoes on radar around Devils Lake, but not sure
these are even reaching the ground. The best instability axis lies
across south central North Dakota, but some CIN remains in place.
Looking for a kicker to arrive later this evening in the form of
the low level jet. This would be expected to get going sometime
around or after dark. Being early June, not too excited about the
prospects of severe weather getting going after dark. However,
timing for any strong to severe storms should be 8 to 9 pm in the
Devils Lake region and late evening to around midnight in the Red
River Valley. Think as the storms transition into Minnesota after
midnight they should gradually weaken. There may be some lingering
pcpn in Minnesota Wednesday morning, but the rest of the day looks
quiet.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 306 PM CDT Tue Jun 5 2018

Sfc high moves over region for Wed night as upper ridge begins to
amplify from northern tier thorugh Sask/Alb provinces. Will see a
break in activity through late Thursday evening, when next shortwave
moves into area with SW flow aloft from srn CA into the Dakotas.  At
the sfc, a warm frontal boundary sets up well south of ND/SD state
line and storms/showers will develop early Fri morning mainly across
sern zones. Frontal boundary lifts to near Hwy 2 corridor by 00Z and
POPs further north than fcst indicated 24 hrs ago. Low confidence in
the lower POPs on Sat as system moves out of area and ECMWF remains
drier than GFS , but easterly flow setting up Sat night into Sun
should keep most of area dry for latter part of the weekend...with
some low POPs for cntrl ND into the Devils Lake region.  A cold
front then moves across the region Sun night into Mon, and looks
like best chance for widespread shra/tsra activity in the Day 2
through 7 timeframe.

&&

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 657 PM CDT Tue Jun 5 2018

All sites currently VFR, with convection expected to move in later
this evening at KDVL and around the 05-06Z time frame for KFAR and
KGFK. Have mostly VCTS and Tempo groups, but included TS at KFAR
in a prevailing group as most of the short range models have a
thunderstorm complex in that area. Most of the convection and
showers will be past us by 10-12Z in the morning, although some
periods of MVFR ceilings behind the system will be possible. All
sites will return to VFR by the end of the period. Winds will
shift around to the northwest behind the convection.
