.KEY MESSAGES...

- Scattered thunderstorms continue early this morning. While
  most storms are not expected to be severe, an isolated strong
  to severe storm or two capable of producing large hail can't
  be ruled out.

- A conditional chance for strong to severe storms exists today
  and Tuesday. There will be additional chances of thunderstorms
  Wednesday through next Sunday.

- Hot and humid weather is expected starting today and lasting
  through this week. Extreme Heat Warnings and Heat Advisories
  have been issued for east-central Minnesota into northwest
  Wisconsin Monday into Tuesday.

.UPDATE...
Issued at 1128 PM CDT Sun Jun 28 2026

Storms have finally made an appearance this morning, though the
potential strength of the storms has lessened considerably.
However, there is one storm moving north that has managed to
break the stout cap that was seen in MPX's 00Z balloon data, so
the possibility for strong to severe storms are not completely
out of the question. Main hazards will be hail and damaging
winds into this morning. CAMS are still trying to catch up, but
the HRRR is doing the best at the moment, representing the
current storms the best. Other CAMS want to continue to predict
the aforementioned line of storms this evening into the
overnight, but the HRRR has backed off from that solution.
Regardless, CAMS still show severe storms expected tonight, the
only question remains where.

It looks like the heat may come to fruition today as there are
already clearing skies behind the few storms to our south. One
snag that remains is that the current cloud cover seems to be
back filling as well. We will see if daytime mixing will help
the clouds to dissipate or if continued warm air advection will
keep the cloud cover up throughout the day.

Rinse and repeat the hazardous swimming conditions at the
beached around the Twin Ports from strong northeast winds
continuing today. A Beach Hazard Statement is in effect.

.DISCUSSION...
Issued at 400 PM CDT Sun Jun 28 2026

This afternoon and tonight:
We have a fair amount of cloud cover over the region this
afternoon, and this has suppressed thunderstorm activity this
afternoon. We do have some clearing down towards the Twin Cities
with some building instability down there where a warm front is
present. This warm front will slowly lift northward tonight, but
the actual surface front will still remain pretty well south of
our area. Elevated instability associated with strong warm air
and moisture advection will gradually increase overnight, and we
may see some scattered showers and thunderstorms develop. CAMs
have been struggling to paint a reasonable picture of what might
happen later tonight as they fail to capture current conditions
well, placing rain showers where none is currently falling. The
overall synoptic pattern tonight will be broad ridging aloft
without much focused synoptic support for storms. Therefore, we
essentially have some factors favoring storms (increasing
instability) and negating factors (lack of broad synoptic
support). Any showers and storms that develop are expected to be
elevated. We will have potential for 2-3k J/kg of MUCAPE, but
that's only if some of the capping can be eroded, which isn't a
guarantee. So, the risk for severe weather tonight looks pretty
isolated. Large hail is looking to be the primary hazard in
addition to the usual thunder/lightning and heavy rain threat
with general thunderstorms.

Monday and Monday night:
As has been the story of this weather pattern, whatever
thunderstorm activity happens tonight will at least partially
determine how storms and heat end up panning out for Monday and
Monday night. In addition to that, guidance in the broader sense
seems to have a bit of a Fujiwara effect between an upper low
over Montana and a trough moving north across the Dakotas
Monday. Convection over there may take more of a northerly
trajectory that could bring the risk for severe weather further
north into Canada. With all that said, we will be dealing with
substantial instability and heat on Monday in our area with 3-4k
J/kg of MUCAPE (most of which will probably be elevated and
capped during the day Monday). Some CAMs bring nearly all
convection north of the Canadian border while some develop a
squall line that, if it happened, could bring a threat for large
hail (to about golf ball size, perhaps larger), strong winds
(to about 70 mph), and perhaps a tornado or two. This would be
most likely in the afternoon through early overnight. This
threat remains very conditional, so stay tuned for updates.
We'll know more once we see how thunderstorms develop Monday
morning across the Dakotas.

As for the heat, it's still looking like it will be a hot day.
The current forecast is largely in line with the NBM, which is
on the upper end of guidance. This means there's at least some
potential for temperatures to be a little cooler than forecast,
but not likely to be warmer. Main concerns with that are
lingering cloud cover and capping that could result in
temperatures slightly less hot than forecast. But there's
definitely high potential for 100 degree plus heat index values
with very high dew points in the mid to upper 70s for much of
east-central Minnesota into northwest Wisconsin. Because of
this, a few Extreme Heat Warnings have been issued for
Pine/Burnett/Washburn counties and a broader swath of Heat
Advisories have been issued for east-central and all remaining
northwest Wisconsin counties. We opted not to issue for the
South St. Louis and Carlton county zone since we will have
onshore flow from Lake Superior that should keep most of the
county from reaching criteria. With that said, the far western
and southern areas of that zone should see ~100 degree heat
indices a ways away from the lake influence. Heat Advisories for
Bayfield/Sawyer counties and east go through Tuesday early
evening as lows are not likely to fall below 70 degrees Monday
night, and we'll see another hot day there on Tuesday with highs
in the 90s and heat indices approaching 100 degrees again.
Moderate to major heat-related impacts are expected in the
advised areas.

Tuesday and Tuesday night:
A cold front will slowly work east on Tuesday, and out ahead of
it, instability will linger mainly across northwest Wisconsin
but also perhaps a ways into east-central Minnesota. We may
start to lose some capping, so that works in favor of there
being some thunderstorms in general. A few storms capable of
producing some large hail and strong winds may be possible, and
timing of those could be morning, afternoon, or both. This
remains a conditional threat much like Monday, but with
increasing likelihood that there will be at least a few storms
out there as the cap starts to erode ahead of the cold front.

It is looking like another hot day, especially in northwest
Wisconsin. On the Minnesota side, dew points and temperatures
take a bit of a tumble, so it won't feel quite as hot as Monday.

Wednesday through the Weekend:
On Wednesday, we'll have to keep an eye on potential for some
more convection with southwesterly flow and a shortwave passing
by aloft. The storm threat could continue into Wednesday night.
MUCAPE in the 1-2k J/kg range may be marginally favorable for
some severe weather. Otherwise, more warm/hot weather is
expected.

General warm southwesterly flow will continue on into the
weekend, so expect more of the same with warm to hot weather and
plenty of chances for thunderstorms. Severe weather may be
possible at times.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 750 AM CDT Mon Jun 29 2026

Crummy flight conditions this morning with some improvement this
afternoon though a supercell (or remnants thereof) will clip
KINL early this afternoon. Another round of convection will
spark this evening and run west to east across the forecast
area. This convection is expected to be severe. Meanwhile, fog
will roll through this morning near Duluth with onshore flow and
thunderstorms over Lake Superior. Thinking this will eventually
break by this afternoon. Winds are generally fairly light out of
the east or southeast except near thunderstorms.

&&

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 1128 PM CDT Sun Jun 28 2026

Rinse and repeat the strong northeast winds for today, making
conditions hazardous for small craft again today into tonight.
Winds will finally decrease for Tuesday to 15 kts out of the
southwest, ending the pattern that we've seen the last few days.
Showers and storms are expected over western Lake Superior for
today and Tuesday capable of producing large hail and gale-
force winds.

Forecast Discussion at weather.gov/mqt.

.FIRE WEATHER...
Issued at 1128 PM CDT Sun Jun 28 2026

Fire weather concerns are low as moist air moves up from the
south for the better part of this week. Tuesday has the best
potential for low RH ranging 35-45%. Gusty winds continue into
this week, starting out of the southeast and switching to the
southwest late tonight. Both days, sustained winds 10-15 mph and
gusts 20-25 mph are expected. Despite the moist air, there is
also hot air as well, with temperatures each day well into the
80s and lower 90s through the week. The only caveat would be
whether increased cloud cover would curb the temperatures in
places expected to reach over 90. Either way, hot and
uncomfortable conditions will persist for the rest of the week.

See the Fire Weather Forecast product for a more thorough
breakdown of fire weather conditions.
