  Heat Warning is in effect Saturday through Sunday for
  southwest MN, with an areawide Watch continuing into Monday.

- The urban heat island of the metro supports higher confidence
  for an Extreme Heat Warning lasting Saturday through Monday

.DISCUSSION...
Issued at 258 PM CDT Fri Jul 24 2026

The forecast is starting to get a little bit busier as we bring
in multi-day heat headlines and several low-end chances for
thunderstorms, some potentially severe. Let`s cover the heat
first.

Extreme Heat Saturday through Monday...A pronounced ridge will
remain centered over the west-central US this weekend, leaving
the Upper MS Valley on the northeastern periphery. Confidence
remains lower than it was for our previous heatwave, given the
chance for elevated smoke which could filter sunshine and
several weak disturbances that could influence storm chances.
That said, guidance continues to suggest dangerously hot and
humid conditions over several days, starting midday Saturday.

A plume of low level moisture advection will increase dewpoint
temperatures into the low-mid 70s, resulting in heat indices
near 100-105F along a corridor centered over the MN river valley
in southwestern MN. WBGT near 87-89F also suggest that heat-
related illnesses will become much more likely when spending
extended periods of time outdoors, especially if exercising. An
Extreme Heat Warning has been issued from Saturday afternoon
through Sunday morning for this area of greatest heat risk. The
Twin Cities metro also has an Extreme Heat Warning starting the
same time on Saturday and continuing all the way through Monday
morning. The hot and humid conditions spread eastward Sunday and
Monday, though with the uncertainties, we have kept everywhere
outside of the metro with an Extreme Heat Watch for now. The
metro will stay warm overnight (mid to upper 70s) such that
confidence remains high for prolonged impacts from the heat. The
heat will continue into next week, but dewpoints and air
temperatures will be about 5-8 degrees cooler than this weekend.

Thunderstorm Chances...Several weak disturbances are expected to
initiate a few rounds of thunderstorms, starting this evening
across eastern ND and northern MN. Most CAMs have focused in on
a similar solution showing scattered storms developing late
afternoon and progressing eastern through the evening. The
majority of the convection likely will fall apart by the time it
reaches central MN given the lack of instability across the
area and warming mid- levels. That said, there is still a
marginal SWO for portions of central MN with the low end
scenario of a storm or two continuing further south than
expected late this evening.

Storms will likely continue moving east across northern MN and
northern WI through the morning, and additional isolated storm
development will be possible along a boundary draped through
western WI and east-central MN.

A fairly broad Day 2 Marginal SWO was introduced across much of
WI and eastern MN, highlighting the chance for isolated
redevelopment tomorrow afternoon. Eastern WI would be the
favored region for any storm initiation due to weaker capping
east of the thermal ridge. Much of MN could be well-capped with
700 mb temperatures expected to be up to +12-15C.

Sunday could end up being a very similar situation with overall
storm coverage remaining dependent on the extent of our thermal
profile. There will be a slightly more favorable environment for
any storms to do form to become severe, as highlighted by the
Day 3 Slight risk.

Additional storm chances will be possible into next week, though
it will continue to rely on this smaller scale disturbances
within the upper level ridge.

.AVIATION /00Z TAFS THROUGH 06Z SUNDAY/...
Issued at 547 PM CDT Fri Jul 24 2026

VFR conditions expected through the period. Skies remain BKN to
OVC at 4-7 kft, becoming FEW to SCT at 5-10 kft this evening.
ISO instances of MVFR CIGs possible through the evening, but
confidence is low so no mention in TAFs. A Cluster of storms
ongoing over central and eastern ND and northern MN will
continue to move east/southeast through the evening, moving into
portions of western and central MN. Confidence remains too low
regarding direct impacts to terminals so there`s no mention of
TS in TAFs. As of now, AXN is where better confidence exist,
but still not enough to mention in TAF.

High resolution model guidance shows additional ISO to SCT
storm development during the overnight and morning timeframe
across western WI and eastern MN. However, with a lot of
discrepancies between run-to-run high res guidance, confidence
remains too low for any mention in TAFs. The increase in low-
level moisture in the morning should support the development of
lower clouds around 2-4 kft across western WI and eastern MN. As
of now, cloud coverage looks to be FEW to SCT.

Winds through the remainder of the evening will be 8-13 knots
sustained with gusts to 20 knots, out of the S/SSW. Winds will
decrease to 5-10 after sunset. Light winds at 5-10 knots persist
through the day, becoming west/northwest by afternoon.

KMSP...VFR conditions expected through the period. ISO
shower/storm will be possible during the morning hours, between
10-14z but confidence is too low so not mention in TAF. SCT
clouds will develop during the morning with CIGs at 2-4 kft.
Confidence is low, but isolated instances of MVFR CIGs will be
possible during around sunrise.

/OUTLOOK FOR KMSP/
SUN...VFR. Chc for -TSRA PM. Wind SSW 8-13 knots.
MON...VFR. W becoming NW at 10-15G25 knots.
TUE...VFR. Wind NW 5-10 knots.
