.DISCUSSION...
Issued at 136 PM CDT Sun Jun 14 2026

For the rest of the day, clouds stuck around a little longer
this morning which has trended RH up just a smidge across the
Northland. However, the HRRR still points to sub 25 percent
values over northeast/north-central Minnesota this afternoon.
These critically low humidity values below 25% are combining
with gusty northwest winds of 15 to 20 mph and gusts up to 30
mph, keeping the Red Flag Warning active across portions of the
Arrowhead region. High temperatures will be unseasonably cool,
only reaching the upper 60s. Tonight, the gusty winds will
diminish as a cooler air mass settles over the region, allowing
low temperatures to drop comfortably into the 40s.

Sunshine will kick off the start of the new work week, but
clouds will quickly increase as a fast-moving disturbance
drops down from Canada. Monday afternoon looks stormy, but
nothing severe is expected as these showers and non-severe
thunderstorms track across the region. Temperatures will
continue to slowly moderate ahead of this system, reaching the
low to mid 70s for most locations.

The overall weather pattern through the middle and end of next
week will be characterized by continuous northwest flow aloft.
This setup will bring multiple quick-moving systems passing
through our area, providing periodic chances for rain and
thunderstorms. Based on the latest guidance, we kept higher
rainfall amounts in for Wed into Thu across the southern 1/3 of
our forecast area. Temperatures will remain near or slightly
below normal through the middle of the week, with highs
generally in the upper 60s to low 70s.

By late Thursday into Friday, broad upper level ridging
currently stationed over the western United States may begin
to drift eastward. This shift would potentially transition our
winds to a more southerly direction, introducing a warm air
advection pattern. As a result, we could see a return to more
typical, warmer summertime weather and drier conditions heading
into next weekend.

decrease tonight before southwest winds increase Monday with

Marais.

.FIRE WEATHER...
Issued at 136 PM CDT Sun Jun 14 2026

Dry and breezy conditions will lead to critical fire weather
concerns for the Minnesota Arrowhead this afternoon. While
clouds stuck around longer this morning to bump relative
humidity up a smidge, high resolution models still point to sub
25 percent values across St. Louis County. This will be paired
with westerly winds gusting 20 to 30 mph. Winds look a bit
lighter for Monday with scattered showers and thunderstorms
returning in the afternoon. Periodic rain chances will then
continue through the middle of the week.

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