.DISCUSSION...
Issued at 238 PM CDT Sat Apr 11 2026

It's a cool and damp Saturday as scattered showers continue to
slide eastward across Minnesota and Wisconsin. These showers and
maybe a rumble of thunder will continue into the evening and
overnight hours, especially for portions of western Wisconsin. A
southwesterly LLJ will kick in this evening, sending a plume of
Gulf moisture northward. Continued cloud cover and very strong
WAA will allow temperatures to gradually increase overnight. A
majority of the forecast area will likely be sitting with both
temperatures and dew points in the upper 50s to low 60s by
morning. We'll have to see how quickly clouds clear out Sunday,
but it seems likely that highs will be some 30 degrees warmer
than today in the upper 70s and low 80s. Winds will turn from
the south to the west by the afternoon, which will work to lower
dew points by 5 to 10 degrees for western Minnesota. There's a
chance that portions of our far southwest see min RH values fall
below 30% during the afternoon and evening with wind gusts
approaching 30 MPH, but for now, it appears that the risk for
elevated fire weather conditions will remain back across the
Dakotas. To the east where Tds remain in the 60s, there is a
question of whether any afternoon convection will be able to
develop. A lot rides on the timing of a weak shortwave and how
long morning showers and clouds stick around. Still, CAMs have
CAPE values AOA 1500 J/kg and ample shear, so a stronger storm
or two is a possibility, especially for western Wisconsin. SPC
has a Marginal Risk in the SWODY2 that covers this threat.

A more favorable severe weather set up is still in the cards for
Monday. A warm front will lift northward during the afternoon with
PWATs increasing to around 1", which is around 200% of normal. Mid
level lapse rates are impressive, but strong capping may limit storm
development initially. There is a fair amount of spread in the
guidance in how far northward the warm front will push, with the
AIFS keeping southern Minnesota in the low to mid 60s and the RRFS
taking upper 70s as far north as St. Cloud. All of this to say,
there is still a high degree of uncertainty in the forecast for
Monday. Tuesday looks like a similar scenario, but likely even
further south and east of our CWA. But again, some strong to severe
storms can't be ruled out entirely at this point. The remainder of
the week remains mild with temperatures in the 70s. We'll see
continued chances for showers and thunderstorms throughout the work
week. Looking ahead, a stronger system may be in the works for the
weekend and I can't guarantee that all precip associated with
this will fall as liquid...

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1233 AM CDT Sun Apr 12 2026

Showers continue over western WI overnight. The arrival of the
low level jet will lead to the inclusion of WS in all TAF sites
tonight. There will likely be another round of storms
developing around 10z just east of MKT that pushes into WI in
around daybreak this morning. I've tweaked the PROB30 -TSRA
sites, but additional tweaks may be necessary overnight.
Fog will continue to spread across portions of central MN
overnight with most sites in IFR through sunrise. For Sunday, a
dryslot will be moving east across MN that will quickly clear
skies and shift winds to the SW by Sunday afternoon. This will
lead to a quick improvement from IFR to VFR late morning into
early afternoon time frame. I've tweaked the clearing timing
across our MN sites, but the timing of our dryline boundary
remains uncertain. W WI sites will stay in the lower MVFR clouds
through mid- afternoon before scattering out. Wind gusts will
peak in the 30 to 35 knot range this afternoon, but gusts should
fall off after sunset this evening.

KMSP... Latest trends suggest the secondary round of TS will
stay to our southeast this morning. For this afternoon, we'll
have a favorable pattern for a southwest cross-wind. Also,
we'll have very deep mixing (possibly pushing 10k feet), so
these will be very gusty cross winds, with sporadic wind gusts
to 40 kts not out of the question given momentum transfer via
forecast soundings.

/OUTLOOK FOR KMSP/
MON...AM VFR. PM -RA likely, chc MVFR/-TSRA. Wind E 5-10 kts.
TUE...VFR. MVFR/-SHRA likely late. Wind NE 5-10 kts.
WED...VFR. Wind lgt and vrb.
