Area Forecast Discussion
National Weather Service Grand Forks ND
1006 PM CDT Mon Jun 13 2022

.UPDATE...
Issued at 1006 PM CDT Mon Jun 13 2022

Storms starting to move into western Benson county, with plenty of
strong instability and deep layer bulk shear to work with. Watch
has been issued for our northwestern counties for this first round
of storms. CAMs show a second round moving into our CWA from
western SD later tonight and into early Tuesday morning, which
fits with more weak shortwaves seen on WV loop as well as
instability and shear continuing into the overnight. Expecting an
active night.

UPDATE Issued at 649 PM CDT Mon Jun 13 2022

Hot and sticky conditions continue with a weakening cap across our
western counties, but convection so far has been mostly further
west under the diffluent flow/embedded weak shortwaves. Some
cells trying to get going further east, but struggling a bit.
Agree with previous forecast that most of our activity will be 03Z
and later. A few minor tweaks to POPs, but will continue
monitoring mode for now.

&&

.SHORT TERM...(This afternoon through Tuesday night)
Issued at 342 PM CDT Mon Jun 13 2022

Main concern of the short term continues to be focused on potential
severe thunderstorms and heavy rain potential later this evening
through Tuesday.

This afternoon-Tonight: SW flow aloft is in place across the Plains
with main region of diffluence/synoptic forcing still over the
western Dakotas/Montana/Wyoming ahead of the deepening upper trough.
Destabilization is occuring and there may be some weakening of the
CAPe that could still allow for a few showers/thunderstorms to
develop into our west, however organized convection is not expected
until later tonight when several shortwaves/periods of positive
vorticity advection rotate over our CWA. Instability axis is
expected to continue to build north and be in place through the
evening ahead of these features and we are already seeing ML CAPE
over 2000 J/KG. Deep layer shear will be in place (greater than 50kt
effective shear) and at the onset hodographs support some supercell
potential upstream a they could track into our CWA in the 9PM-1AM
period which some CAMs had shown stronger/longer UH tracks towards
our western CWA. We have the advantage of watching upstream trends
for development for the early part of the event. when these higher
impactful storms could occur.

As forcing increases mean wind vectors runs parallel to the main
front and forward momentum isn't as likely. This will favor clusters
of showers/thunderstorms while elevated instability slowly weakens
through Tuesday morning. This transitions to more of a hail/wind/heavy
rain threat, and heavy rain in particular could be an issue if
clusters track slowly northeast over similar locations as PWATs will
be high (around 1.5" or higher).

Tuesday: Due to a shift in flow to the west drier BL flow arrives
west to east shifting the instability axis eastward through midday
and completely east of our CWA by late afternoon/early evening.
Remnant clusters will tend to carry mainly a heavy rain threat with
some embedded stronger cores through 9AM, but trends show this
quickly weakening as it transitions eastward. There is a window in
our far east where we may have enough instability for redevelopment,
but confidence is lower after the initial morning period (may see
stabilizing trends during the afternoon ending the thunderstorm
threat early).

.LONG TERM...(Wednesday through Monday)
Issued at 342 PM CDT Mon Jun 13 2022

The extended forecast period looks to offer opportunities for
several types of impactful weather, ranging from severe early, to
fire weather, before ending with extreme weekend heat.

Wed is looking to see the upper trough transitioning north of the
international border as surface low continues to deepen as it
progresses northeastward as well. Owing to a strong pressure
gradient, the NBM probabilities for wind gusts exceeding 40 kts are
in the 50-70% range from the Red River Valley westward. This will be
accompanied by the conditional threat for severe weather principally
across northwest Minnesota as the surface low and cold front look to
spark some convection Wed afternoon.

Impacts from convection will give way to fire weather concerns Thu
and then onto higher heat indices in time for the weekend. Signal
exists for 20 to 30 kt NW breezes Thu afternoon from the Devils Lake
basin through the Red River Valley. Humidity minima will be the
question mark, currently we are going with values above 30 percent,
but any mixing of drier air to near surface will bolster the potential
for fire weather impacts.

Upper ridge builds solidly over the forecast area Fri and into the
weekend,  and with this the mercury will be on the rise. NBM 50th
percentile values generally over 90 degrees everywhere on Sat and
closer to 100 for Sun. And the temps will combine with blast
furnace type winds out of the south sustained at 20 kts or better
for a good part of the time on Sat, a little lower for Sun. So
heat advisory/warning decisions will be the weekend challenges.

&&

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 649 PM CDT Mon Jun 13 2022

VFR conditions currently, but should see some deterioration later
tonight as storms and surface trough axis move east into our area.
For now just have KDVL with VCTS and CB during the 03-15Z time
period, with a shorter period of convection possible at KGFK. MVFR
and then IFR ceilings coming in later tonight as moisture
continues to come up from the southeast. Think KFAR should see
some improvement back to VFR by the end of the period but rest of
the airports will be stuck in the moisture plume into Tuesday
afternoon. Winds will shift to the southwest then west by the end
of the period as the low pressure system pushes eastward.

This hazardous weather outlook is for portions of eastern North
Dakota, west central and northwest Minnesota.

.DAY ONE...This Afternoon and Tonight

A few thunderstorms can't be ruled out through the early evening,
but best chances are after 9PM through the overnight. We should
see storms develop upstream over western and central ND and SD
that will track into in eastern ND late this evening, and move
into NW and west central MN through the overnight. The strongest
of this activity will be capable of golf ball size inch hail,
winds gusting around 60mph, excessive rainfall and possibly a
tornado. The tornado threat is mainly through 1 PM. at the onset
of the event.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Storms will most likely be ongoing Tuesday morning across the area
with the strongest storms capable of hail up to 1.5 inches and
winds gusting to around 60mph. This activity will lift north and
be out of the area by evening. Wednesday may see some storms
develop with daytime heating once again with hail and wind
potential along the valley into NW MN. By the weekend heat indices
will rise to 95 and 105 the hottest temps of the season so far.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be required this evening through Tuesday
morning.
