Area Forecast Discussion
National Weather Service Grand Forks ND
646 AM CDT Sat Jun 16 2018

.UPDATE...
Issued at 646 AM CDT Sat Jun 16 2018

Thunderstorms moving out of NE SD should reach Fargo around 9 AM.
Could be borderline severe. The latest HRRR has the complex moving
NE and reaching Bemidji by late morning/noon. Updated chances of
rain and weather grids based on this thinking. &&

.SHORT TERM...(Today and tonight)
Issued at 302 AM CDT Sat Jun 16 2018

Southwest flow aloft dominates the Northern Plains as a ridge
axis exists over the Great Lakes and an upper low over the Pacific
Northwest. Upper/mid level heights fall slightly today as an
upper wave passes to the north of the area in the SW flow. A
surface frontal boundary exists from Lake of the Woods southwest
through northeast SD. A warm front extending eastward over
southern/central MN will lift northward today. CAMs have
convection increasing this afternoon in the vicinity of the front
and northward across the central part of the forecast area...aided
by a 40 kt low level jet and MUCAPEs of 2000-5000 J/kg. While
some thunderstorms may develop during the afternoon along the
warm front and northward, activity is also expected to develop
over western/central ND as well and move east through the Red
River Valley during the afternoon/evening. There is still plenty
of uncertainty regarding how things will evolve, however. Given
the moist conditions/low LCLs and good deep and low level shear,
the Significant Tornado Parameter is around 2 from
Gwinner/Fargo/Bemidji and south this afternoon/evening. A 2-5%
tornado risk from the SPC exists in this area today. This risk
exists from both discrete supercells and QLCS mesovortex
potential. Also...an excessive rainfall potential exists in this
area today/tonight. While the threat for thunderstorms exists over
the entire area this afternoon and evening, the focus will shift
further south/closer to the warm front after midnight tonight.

Otherwise...expect warm and muggy conditions in the south
today and upper 60s in the far northwest. Generally, partly sunny
skies with increasing cloudiness are expected as well.

.LONG TERM...(Sunday through Friday)
Issued at 302 AM CDT Sat Jun 16 2018

An active period will continue into Sunday as an inverted trough
stalls over northern MN into northeastern SD.  This will keep a
threat for thunder across the southeast, with rain showers in the
more stable airmass to the northwest. Showalters are showing
negative values for the southeastern corner of the CWA Sunday and
Sunday night. The strongest storms will be along the best
instability axis most likely SE of our CWA. SW flow aloft will bring
a series of shortwaves through the northern tier, so the main
challenge will be timing of precipitation and will not likely be as
long in duration as blended solution POPs represent. Confidence in
blended solution POPs continues to be low for Sunday night and
Monday as the GFS and NAM are dry Sun evening, while the ECMWF shows
a band of showers/storms across the south.  NAM shows a much tighter
north-to-south POP gradient, which makes sense given the drier
northeast flow into the northern zones.  Would expect subsequent
model blends to further reduce POPs across the north...with overall
forecast becoming dry for the majority of next week as sfc high
pressure dominates and the main storm track/jet energy flows across
northern Canada.  The dry weather and increased solar should help
temperatures rise into the 80s in the valley, and upper 70s outside
of the valley, by Tue and remain in the mid to upper 80s across the
region through the remainder of the next work week.  Increased cloud
cover and chances for showers or storms will result in Saturday
cooling back down into the 70s.

&&

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 646 AM CDT Sat Jun 16 2018

Occasional thunderstorms and low cigs will plague the region over
the next 24 hrs. FAR will likely see thunderstorms by 14Z moving
out of SD. BJI may see this by 17Z as well. Otherwise,
redevelopment is expected this afternoon. Cigs will likely be in
the MVFR category off and on through the period.
