.DISCUSSION...
Issued at 322 AM CDT Sun Sep 7 2025
Today - Tonight:
Prominent surface high pressure settling into the Dakotas and
Minnesota has led to clearing skies and calm to light winds over
most of the Northland. One exception will be some cloud cover
that should continue to linger in Lake and Cook counties
through the overnight hours due to subtle shortwave energy on
the backside of an exiting mid/upper-level shortwave to our
east. Areas outside of this cloud cover region have already seen
temperatures drop into the mid 30s to low 40s, with forecast
lows forecast to bottom out in the low to mid 30s for most of
the Northland inland from Lake Superior by around sunrise. Given
this, we decided to expand the Frost Advisory to now include
everywhere besides southern Lake and Cook counties along the
North Shore. The Freeze Warning also remains in effect for
Koochiching County as well as northern and central St. Louis
County where ensemble probabilities of 038.
WI...Frost Advisory until 8 AM CDT this morning for WIZ001>004-
     006>009.
MARINE...None.
