...BEACH HAZARDS STATEMENT NOW IN EFFECT UNTIL 10 PM CDT THIS
EVENING...

* WHAT...Dangerous swimming conditions are expected along the 
  Lake Superior shoreline due to high wave action and strong rip 
  currents. 

* WHERE...Minnesota Park Point and Wisconsin Point Beaches.

* WHEN...Until 10 PM CDT this evening. Conditions improve
  significantly through this afternoon.

* IMPACTS...High wave action can make swimming difficult on days
  such as this. Incoming waves in rapid succession can tire even
  an experienced swimmer quickly. Rip currents can move you away
  from land. To avoid being swept away, swim parallel to the shore
  to exit a rip current.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Remain out of the water to avoid hazardous swimming conditions.

.KEY MESSAGES...

- Rain showers during the current overnight hours become more
  isolated to scattered today.

- 10-20% chance of isolated storms Sunday afternoon-eve and
  Sunday night/early Mon AM.

- Summer-like heat arrives for Memorial Day and continues
  through much of next week, with high temperatures in the 80s
  for most inland locations. Some locations could see low-90s on
  Tuesday.

- Much of next week will be primarily on the drier and sunnier
  side, though there will be isolated shower/storm chances at
  times. Potential for near-critical fire weather conditions
  will need to be monitored closely each afternoon into early
  evening next week.

.UPDATE...
Issued at 336 AM CDT Sat May 23 2026

Added a 10-20% chance of storms to northwest Wisconsin Sunday
afternoon and early evening. Instability is forecast to build as
temperatures warm into the middle and upper 70s. Several
deterministic models feature a few showers/storms percolating on
the nose of the instability gradient. These storms are in
addition to the small chance of storms from Isabella to near the
Twin Ports to Bayfield Sunday afternoon.

MLCAPE of 500-1000 J/kg, 30-35 knots of 0-6km bulk shear, steep
mid-level lapse rates around -7.5 C/km, and dry air aloft
suggests a potential for penny to half-dollar size hail. The
main limiting factor for storm development is a lack of forcing
for ascent. Relatively weak low-level flow and very warm
temperatures over the land may allow a lake breeze to push
inland from Lake Superior during the afternoon, which may
provide focus for ascent. High-res guidance does not indicate a
lake breeze developing as of this morning. Forecast trends will
need to be monitored in case the environment becomes more
favorable for severe storms. As of early this morning, the
potential for severe storms is less than 5 percent.

A strengthening LLJ over north-central Minnesota continues to
support a 10% chance of thunderstorms Sunday night into early
Monday morning. These storms are not expected to be severe.

.DISCUSSION...
Issued at 100 AM CDT Sat May 23 2026

Current Overnight - Today:

An upper-level trough across eastern North Dakota and attendant
surface low tracking north along the western MN border during the
current overnight hours will continue northward today into southern
Manitoba and far northwest Ontario. The best synoptic forcing and
shower coverage is currently in far northern MN, the Arrowhead, and
portions of far NW WI. Can't rule out a few rumbles of thunder
during the overnight hours, but the potential is low (10-20%) and
mainly relegated to far NW WI. No severe weather is expected.

Rain showers become more isolated to scattered for today as the
better forcing for ascent moves north with the low pressure, then
exit to the east of the Arrowhead and north-central WI late this
evening. Additional forecast rainfall amounts range from a few
hundredths of an inch to around 0.15" in north-central MN and much
of NW WI and 0.1-0.35" in the St. Croix River Valley north into the
Arrowhead and far NE MN. Plenty of cloud cover hangs around today
with breezy southeast winds in the morning becoming southwesterly
behind the occluded front in the afternoon to early evening as it
moves through. High temperatures inland from Lake Superior will warm
into the 60s to low 70s, warmest south. Areas in the Twin Ports and
along the North Shore/Arrowhead will see cooler highs in the 50s due
to onshore flow from Lake Superior.

Strong onshore winds and wave heights to around 3-4 ft this morning
into afternoon will once again create the potential for rip currents
for Minnesota and Wisconsin Point Beaches today. A Beach Hazard
Statement will likely be needed.

Sunday - Monday Morning:

Additional mid- and upper-level energy pinwheeling around the upper-
level low could kick off additional isolated showers/non-severe
storms across north-central MN into the Arrowhead from early Sunday
morning into midday Sunday.

Otherwise, expect Sunday to be the start of a strong warming trend
as southwesterly winds advect warmer air into the Northland. Look
for widespread high temperatures in the 70s and pockets around 80F
away from the immediate vicinity of Lake Superior, with slightly
cooler temperatures near the Lake and for the North Shore under
primarily sunny skies. Weak shortwave energy moving through largely
zonal flow aloft later Sunday evening into early Monday morning
combined with some instability aloft and 30 kt of bulk shear could
kick off some scattered, elevated showers and storms.

With warmer temperatures and primarily sunny skies for many areas on
Sunday, low relative humidities could lead to near-critical fire
weather conditions as minimum afternoon relative humidities dip into
the 25-35% range from the Brainerd Lakes east to inland NW WI. If
heating and afternoon mixing exceed the current forecast, minimum
afternoon relative humidities could dip below 25%. Daytime
southwesterly wind gusts will also be breezy, but gusts should
largely remain at or less than 20 mph.

Memorial Day through the Coming Work Week:

The summer-like heat really cranks up for Memorial Day and Tuesday,
though hot temperatures will continue through much of next week.
This is due to an anomalously strong ridge aloft moving over the
central CONUS and Upper Midwest. High temperatures on Monday will be
widespread 80s away from Lake Superior and slightly cooler near the
Twin Ports and North Shore. Tuesday will be the hottest day with
widespread high temperatures in the upper 80s to low 90s away from
Lake Superior, with some relief in the Twin Ports and near Lake
Superior given some weak easterly onshore flow. Both Monday and
Tuesday have the potential to approach record high temperatures in
several locations. Heat Advisories may be needed for portions of the
Northland on Monday and particularly Tuesday.

Well-above average temperatures inland from Lake Superior are
favored to continue into mid to late next week as some flavor of an
omega blocking pattern sets up, keeping the ridge axis in place
overhead. Temperatures will gradually decrease by a few degrees each
day from Wednesday through the end of the week as winds turn more
southeasterly to easterly While predominately sunny skies are
expected each day next week and little to no forcing for ascent will
be in the area, the hot days could set off some isolated pop-up
showers and non-severe storms, mainly in the afternoon into evening
hours during and on the tail end of peak daytime heating.

This combination of heat and primarily drier conditions could also
reintroduce periods of fire weather concerns each afternoon into
early evening through the coming week. While winds during this
period should be on the lighter side with peak daytime gusts mainly
less than 20 mph, forecast minimum afternoon relative humidity
dipping to 25-35% each day in addition to many areas not being fully
greened-up yet will need to be watched closely for near-critical
fire weather potential.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1236 AM CDT Sat May 23 2026

Ceilings are expected to lower overnight to MVFR to IFR with
little improvement expected this morning. Ceilings will slowly
improve this afternoon into this evening. Showers will continue
this morning with MVFR visibilities at times. A strong southerly
low-level jet will sustain LLWS at the terminals early this
morning and will slowly end from west to east as the jet weakens
and veers this morning. Winds may become gusty this afternoon.

&&

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 100 AM CDT Sat May 23 2026

Gusty east to northeast winds of 15 to 25 kt continue this
morning and linger near the Twin Ports to Silver Bay into this
afternoon. Wave heights of 2 to 5 ft gradually diminish
throughout this morning and early afternoon. Small Craft
Advisories remain in effect for the nearshore waters. Calmer
conditions on western Lake Superior develop for the next several
days as a substantial warming trend occurs into next week,
setting up a stable marine layer.

Forecast Discussion at weather.gov/mqt.

.FIRE WEATHER...
Issued at 100 AM CDT Sat May 23 2026

While rain showers become more isolated to scattered for much of
daytime Saturday, cloudy to mostly cloudy skies linger through
the daylight hours today. Additional amounts will range from a
few tenths to around 0.15 inches in north-central MN and much of
NW WI, and 0.1 to locally 0.35" in the St. Croix River Valley
north into the Arrowhead and far NE MN. This will likely quell
fire weather concerns for today as minimum afternoon RH is
forecast to dip to 45-50% in the NW WI Pine Barrens and above
50% elsewhere. Temperatures warming well-above normal for next
week and a pattern largely favoring plenty of sunshine and
mostly dry conditions aside from occasional, isolated showers
and storms will bring back concern for potential near-critical
fire weather conditions each afternoon into early evening. Most
days will see minimum relative humidities dip into the 30s (%)
over a large area, with pockets of sub 30% min RH values. This
pattern should have largely less gusty conditions, with daily
winds around or less than 10 mph and gusts under 20 mph during
peak daytime mixing.

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