June 7 to 8, 2019 · NWS FGF · 3 events in 3 counties and zones

As a cold front moved into the Devils Lake region during the early evening of June 7th, thunderstorms broke out along the front. Although the front stalled, storms continued to form and dissipate as far east as the northern Red River Valley during the late evening and early morning hours of the 8th.

Area Forecast Discussion
National Weather Service Grand Forks ND
1154 PM CDT Fri Jun 7 2019

.UPDATE...
Issued at 1005 PM CDT Fri Jun 7 2019

Thunderstorm cluster moving northeast of Devils Lake basin with
isolated activity further southwest. Guidance still supports
potential for redevelopment though the evening, but next
round/period of better coverage later tonight as mid level
impulse over SD moves over our CWA within southwest flow.
Adjustments made to near term trends.

UPDATE Issued at 753 PM CDT Fri Jun 7 2019

Adjustments made to timing of PoPs/Wx to account for ongoing
activity and latest trends in CAMs. Also expired Wind Advisory at
00Z. While a few locations continue to gust 40-45mph overall
trend is toward decreasing gusts and this should continue as
mixing decreases.

UPDATE Issued at 446 PM CDT Fri Jun 7 2019

Expanded Wind Advisory to cover the rest of our ND counties
including Fargo as 45 mph winds are starting to be reported in
those areas. Still expect improvement by 7PM (00Z).

&&

.SHORT TERM...(This evening through Saturday night)
Issued at 318 PM CDT Fri Jun 7 2019

Convection timing and strength will be the main challenge for the
period.

Elevated showers continue over our far northwestern counties close
to the surface trough, but the rest of the region remains windy
and hot this afternoon. With quite a bit of mixing, dew points are
mainly in the 50s and there have been some reports of blowing
dust. SPC mesoanalysis has some 1500-2000 J/kg of ML CAPE under
the cap, and approaching weak vorts coming up the southwesterly
flow will provide some upper support for storm development along
the surface trough axis this evening. There continues to be some
variation in the CAMs models on timing of convection developing in
the northwestern counties, but there seems to be some convergence
on the 23-01Z time frame. Deep layer bulk shear is not very
impressive until the upper ridge axis moves further east, but SPC
meso page has some effective shear around 25-30 kts across our
northern counties and better shear further west that will come in
later tonight. The SCCRAM has some 15-20 percent probabilities of
severe hail in the next 4 hours, and there is some good chances of
over 100 m2/s2 updraft helicities. Tornado threat does not seem
very high due to high bases expected for the thunderstorms. At
this point will continue to message hail threat over Devils Lake
Basin this evening, with some spreading into the northern RRV
later tonight.

CAMs have a weakening trend to convection after 06Z, with showers
lingering over at least the northern forecast area through tonight
and tomorrow morning. Another stronger shortwave will move up the
southwesterly flow tomorrow, with the surface trough and a cold
front moving into the RRV. Depending on what happens tonight,
there could be another round of thunderstorms developing along the
cold front tomorrow afternoon. Bulk shear is not very impressive
until the front passes and instability decreases, but there could
be enough overlap for some isolated severe potential. Temps
tomorrow will be very dependent on the front and when convection
fires. For now have mid 80s ahead of the boundary in our MN
counties but mid 60s in the Devils Lake Basin with the strong cold
air advection. Temps should drop into the 40s and 50s Saturday
night with some lingering showers and thunderstorms as the cold
front pushes the rest of the way through.

.LONG TERM...(Sunday through Friday)
Issued at 318 PM CDT Fri Jun 7 2019

Some rain and a few thunderstorms may continue into parts of Sunday
morning, but most of the day should be dryer as the cold front will
be well into eastern Minnesota by Sunday. With the passage of this
cold front temperatures on Sunday and for the next week will be
cooler with high temperatures generally in the 60s and 70s.

Dry start to the work week with surface high pressure leading to
dry, but continued cooler weather. By the middle of the work week a
shortwave is expected to move across the Northern Plains to bring us
our next chance for rain. Models have come into better agreement
with timing of Tuesday evening into Wednesday morning. The placement
and evolution of the surface low still differs between ECMWF, GFS,
and RDPS guidance. This difference also continues with instability
as the GFS for this period has over twice as much CAPE as the ECMWF.
This is continued from the overnight runs with the GFS around 1500
J/kg and the ECMWF around 500 to 750 J/kg. Regardless should
support chances for thunderstorms Tuesday into Wednesday, but the
possible strength of these thunderstorms remains uncertain.

After the midweek system surface high pressure returns on Friday
brining an end to the rain chances. Thursday also marks the beginning
of a warming trend with a return to above normal temperatures.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1151 PM CDT Fri Jun 7 2019

THunderstorm cluster tracking across northeast ND impacting KGFK
and may pass just northwest of KTVF as it moves into far northwest
MN. Isolated activity may begin to redevelop over the next few
hours in southeast ND before the next cluster of
showers/thunderstorms tracks from southwest ND across northeast
ND. Low level wind shear also impacting most TAF sites as low
level jet increases early in the TAF period. Coverage of
showers/storms should decrease Saturday morning, but then the
main system/front moves through the region Saturday afternoon with
increasing chances at all terminals and better potential for sub-
VFR conditions.
