.UPDATE...
Issued at 943 AM CDT Mon Sep 22 2025
Fog this morning is becoming less widespread, with some patchy
fog still being observed across portions of Beltrami County and
Griggs County. Temperatures are generally in the upper 50s to
low 60s with light and variable winds.
UPDATE
Issued at 701 AM CDT Mon Sep 22 2025
Fog has remained most consistent in the far eastern fcst area
from Baudette to Park Rapids where the dense fog adv is out.
West of there there is a rather narrow zone of ground fog (seems
that way from webcams) from Cavalier to just west of Grand Forks
thru Mayville and scattered down to Wahpeton. In an earlier
update I did just expand fog mention to all areas as there has
been a few fog areas via webcams around New Rockford and
Cooperstown. I also updated this upcoming late Monday night for
some fog in the east as this matched neighboring WFO`s and put
in fog based on forecast vsbys 06z-14z Tue period.

.DISCUSSION...

...Synopsis...
500 mb low right over Duluth early this morning. Clouds finally
cleared out of the Baudette and Bemidji areas early Sunday
evening, but with the last clearing and calm winds fog quickly
formed in this area and will remain thru mid morning. Some
patchy fog may form as well farther west into the RRV, with HRRR
indicating some fog forming in the southern RRV.
The overriding theme this week into the weekend is dry and warm.
Upper level ridging builds east into south central Canada and
far northern Plains this week as main jet and moisture reside
well to our south. Stable upper air pattern and looks to persist
for about 10 days into early October. Above normal temps and no
frost concerns in this 10 day period. Considering the wet
weather of the past few weeks, a dry period is very welcome by
most.
