.DISCUSSION...
Issued at 247 PM CDT Wed Jun 10 2026

...Synopsis...

A lead shortwave will come off of the main upper trough
currently over the northern Rockies/Plains, lifting through our
CWA this afternoon and off into southern Canada tonight. The
trough axis/frontal boundary will push through our MN counties
and be through most of the CWA by this evening. The main upper
trough starts to move off into the Upper Midwest and Ontario
tomorrow and tomorrow night. Quite a few rain showers being
produced by models under fairly cool air aloft, but CAPE values
look to be less than 500 J/kg so severe threat is minimal.
Northwesterly flow aloft sets up for the weekend and into the
first part of next week, with a few weak reinforcing shortwaves
moving through.

...Severe threat this afternoon...

With the SPC meso page showing around 1500-2000 J/kg ML CAPE and
effective shear in the 35 to 40 kt range, the severe threat will
continue over our eastern counties for at least the next few
hours. Some showers and thunderstorms have also developed behind
the cold front near Jamestown but instability is much weaker.
Cooler temperatures and drier dew points on the backside of the
surface trough, so most of our deep convection will be out ahead
of it. Severe thunderstorm watch in effect for our MN counties
through 01Z, but will likely be able to cancel before then as
most of our severe threat will be over after the cold front
pushes through. SSCRAM probabilities around 25 to 30 percent for
severe hail currently drop off quickly below 10 percent,
although the HRRR still tries to develop some convection over
the northern Red River Valley later this evening. Low level
shear is not too impressive, and tornado activity isn't super
likely. However, hail up to 1.5 inches and winds to 60 mph will
continue as the cold front moves across northwestern MM.

...Cooler and breezy weekend into next week...

Warm signal in the ECWMF EFI just for today and into Thursday
morning, then flips over to cooler than climo temperatures.
Nothing really impactful, but a break from head advisory
conditions we saw yesterday. Low pressure over southern Canada
will continue to bring a pretty tight pressure gradient through
the end of the work week and into the weekend. Decent mixing up
to 800 mb, but even the bullish BUFKIT soundings stay below wind
advisory criteria. Breezy conditions look likely, but nothing
warranting messaging at this point.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1246 PM CDT Wed Jun 10 2026

Some of the TAF sites have gone down to MVFR or low IFR as
cumulus has started to bubble along the cold front close to the
Red River. But the main impacts during the next few hours will
be convection. KDVL is behind the cold front and may see a few
stray showers, but most of the thunderstorms will be at KFAR and
the MN airports. Have some prevailing thunder for KFAR for a
short time as some lightning producing convection moves in
during the next hour, then VCTS and tempo groups for it and the
MN airports as convection becomes less certain. Convection
should move east of most of our airports by 00Z, leaving VFR
conditions and southwest to west winds at 10 to 15 kts. Winds
will pick up from the southwest and northwest late in the
period, and most model solutions bring some MVFR ceilings into
KDVL tomorrow morning, so included it in the TAF.
