.MESOSCALE UPDATE...
Issued at 901 PM CST Mon Jan 13 2025

Rest of tonight...

Clear & calm night is on tap across the region. With flat zonal
flow becoming established, nearly 1030mb sfc high sagging into
the area overnight & dry moisture profiles, favorable radiational
cooling is expected. Lows will be seasonably cool, some 5-8F
below (23-31F). Widespread frost can be expected in the morning
time. Updates will be out shortly. /DC/

.DISCUSSION...
Issued at 305 PM CST Mon Jan 13 2025

Through Tomorrow:

In the wake of a cold front passage today, mostly clear skies and
building high pressure will set up good radiational cooling
potential.  It`s not the most ideal given some increased soil
moisture, but we expect a widespread frosty morning with temps
ranging from the lower to mid 20s in our northern zones to upper
20s/near 30 in our southern zones. Leave a few minutes extra to
start your morning commute in case the windows are frosty. Then fair
and dry conditions continue into tomorrow daytime as the chilly post-
frontal air brings us widespread high temperatures in the lower to
mid 50s. /NF/

Wednesday through Monday: SFC high pressure will build into the
lower MS-River valley and remain through much of the work week. Dry
conditions are expected until late Thursday into the weekend ahead
of an approaching cold front. As mentioned above, chances for rain
return Thursday as zonal flow aloft weakens and a series of
disturbances swing through the area steadily increasing rain chances
through the weekend. Between Saturday night and Sunday afternoon a
strong cold front will sweep through the area from the northwest
limiting rain chances to mainly the southeast to begin the next
workweek. Temperature wise can expect temps to warm gradually to
well above climo with low temperatures >10 degrees above climo by
Saturday as strong southerly wind-flow prevails across the area.
Following the passage of the cold front winds will become
northwesterly as strong arctic air plunges into the region. Once
again, we will see highs warming to just above freezing by Monday,
and low temperatures in the 20s. There is a low chance for some
wintry precip Sunday night into Monday as precip chances overlap the
period of coldest temps. This is still a week away, so be sure to
stay updated with the forecast this week.
