.DISCUSSION...
Issued at 254 AM CDT Mon Sep 23 2024

A quiet week is expected across the Northland with dry conditions
for most through next weekend. An upper level trough will dive
southeast today into the Northern Plains, continuing southeast
tonight. This feature will have limited moisture available and much
of the guidance, including most of the 80 ensemble members of the
ECMWF/GFS, have little precipitation with this trough for tonight
into Tuesday. We will carry low, 20-30%, POPs for western portions
of the Northland tonight with QPF less than 0.10". Tonight will
again be cool, especially for the Arrowhead and interior portions of
northwest Wisconsin where some patchy frost could again occur. If
cloud cover is more extensive than currently forecast, we may be a
bit low on our temperatures.

The upper trough will continue south on Tuesday eventually cutting
off and retrograding across the south-central CONUS. Upper ridging
will move east over the Northland mid-late week and with the upper
low to the south, creating a rex block which will aid in keeping the
Northland dry into Saturday with high temperatures rising 10 to
around 15F above normal by mid-week with these warmer temperatures
continuing into the weekend.

Patchy fog was occurring early this morning over portions of
northwest Wisconsin west at a few locales in central to

conditions with some mid to high clouds passing through. An
upper level trough will arrive tonight and could cause some
light rain in spots, mainly from the Brainerd Lakes region on
north to the International border. VFR conditions are expected
with any light showers.

Winds are expected to be at or less than 15 knots with a few
higher gusts over central to northern Minnesota.
