.DISCUSSION...
Issued at 241 AM CDT Thu May 7 2026

Current temperatures across the area largely in the 30s, except
from a few upper 20s in west-central MN where skies have
remained clear. Expecting us to cool off a few more degrees by
this morning, but with dewpoints in the mid to upper 20s, not
foreseeing widespread frost. We'll have to see if our WI
counties under a Frost Advisory verify. Radar imagery is showing
some scattered light returns across southern MN. But, looking
at MnDOT road cameras it seems like no precipitation is reaching
the ground. A brief warm up to end the work week begins with
today's highs being in the mid 50s to lower 60s while Friday's
are forecast in the mid 60s to near 70s. Each day also looks
favorable for deep boundary layer mixing, so have used the HRRR
to slightly lower dewpoints (and RHs) during the afternoon
hours. No precipitation is expected through Friday, so with the
warmer temperatures it will be a nice end to the work week,
particularly Friday.

Scattered showers are possible from central MN to northwestern
WI during Saturday morning as a mid-level shortwave and
surface cold front pass through the Upper Midwest. Currently
have 20-40% PoPs over our northern and northeastern counties so
not expecting anything significant. But at least a few raindrops
would be welcome after a dry last several days. The rest of the
weekend looks dry as cooler air behind the cold front is
advected into our area. Highs will return to the mid 50s to
lower 60s Saturday and Sunday. Frost/freeze concerns could also
return Saturday night and Sunday night, especially over central
MN and west-central WI where lows are forecast in the lower 30s.

Temperatures should trend normal to above normal throughout next
week as upper-level ridging over the western CONUS tries to move
into the central CONUS. Though, deterministic models and
ensembles show decent agreement that this progress may be
briefly stalled around Tuesday. One last shortwave from our
prolonged northwesterly flow is favored to pass through during
this time period, which would bring a chance of rain and an
attendant cold front. But after mid- week, widespread highs in
the 70s look likely with even lower 80s coming back into the
picture towards next weekend. Long-range ensembles generally
suggest upper-level ridging to have success reaching the central
CONUS. Indeed, the Climate Prediction Center's 8-14 Day
Temperature Outlook shows a welcome sight: above normal
temperatures favored for the Northern Plains. Near normal
precipitation is favored so a significant rainfall pattern
doesn't appear to be on the horizon. However, the warmer airmass
should have more moisture associated with it that a
hypothetical future shortwave could take advantage of.
