.UPDATE...
Issued at 627 PM CDT Wed Jul 28 2021

The front appears to have pushed through the FA now, but the high
dew points still lag well behind the wind switch. However, relief
is coming, as 50 dew points have entered the northern Red River
Valley and portions of the Devils Lake region. The last of the
early evening showers and storms are up around the Upper and Lower
Red Lakes, moving quickly southeast. So expect within the next
hour or so, the FA will be quiet again. With the drier air slowly
filtering in and decreasing winds overnight, temperatures by
morning will be a tad cooler than recently observed.

&&

.SHORT TERM...(This afternoon through Thursday night)
Issued at 322 PM CDT Wed Jul 28 2021

Isolated severe thunderstorms are still possible this afternoon,
maybe into the early evening, though chances may be decreasing.

Cold front continues to move south and east with a prefrontal trough
still lingering over northwest and west central MN. Along/ahead of
this axis high instability is in place, but stronger CAP due to
stratus/convective debris from earlier activity today has limited
further initiation. There is some clearing in immediately ahead of the
front and may be allowing for better low level lapse rates/weakening
of the CAP, however the window is slowly closing in our CWA as the
this transitions eastward along wit the main axis of WAA/theta-E
advection in MN. High sheer with veering profiles overlap this
unstable air mass, so supercells would be possible within this
environment if a stronger updraft is able to get going. Confidence
is decreasing in initiation, but last few runs of HRRR still show
isolated cells developing immediately ahead of the front in our east
with short UH tracks for cells that do develop (we aren't out of the
woods yet but we are getting close). Impact messaging is in line
with potential supercell development (2 inch or greater hail, winds
to 75 mph, and isolated tornado).

Rest of tonight-Thursday: Seasonable air mass returns to our CWA
with northerly flow behind the cold front and dry/stable air. Once
the flow shifts more to the north instead of northwest late
tonight/Thursday morning smoke from Canadian fires may increase into
northern MN and latest HRRR smoke model shows max surface smoke
concentrations moving into north central and northwest Mn towards
the RRV. So, while temps may be nice we may also see a return of air
quality issues.

.LONG TERM...(Friday through Wednesday)
Issued at 322 PM CDT Wed Jul 28 2021

Friday into Saturday...

Ridging aloft will continue to retreat south and westward throughout
the long term period. As this occurs, we will look to transition
into a northwesterly and then possibly meridional flow pattern
aloft. One outcome of this pattern shift will be a return to more
seasonable temperatures across the region for the end of the week
and continuing into next week. A ridge riding shortwave trough is
also expected to traverse the area late Friday into Saturday, and
may introduce the potential for a few showers and thunderstorms to
northwestern Minnesota. Otherwise, Saturday looks to remain quiet
and dry with widespread high temperatures in the low to mid 80s.

Sunday into next week...

As the dominant area of ridging aloft continues to weaken, it looks
like seasonable and quiet weather ahead to round out the weekend and
move into next week. While a gradual warming trend will take hold as
next week progresses, we should be able to stave off the 90s, at
least through the early week period. The next shortwave is then
progged to potentially arrive late Tuesday and bring with it the
next chance for showers and thunderstorms.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 627 PM CDT Wed Jul 28 2021

North winds will stay gusty at KDVL/KGFK/KFAR for another hour or
so, then they should decrease again. The lower level cloud cover
should also decrease through the evening, leaving just some
higher clouds or high level smoke. North winds within the valley
(KFAR and KGFK) may get a little breezy again Thursday afternoon,
but not like today.
