.MESOSCALE UPDATE...
Issued at 937 AM CDT Sat Nov 1 2025

After a rather chilly start, temperatures were warming nicely this
morning. Satellite imagery showed high clouds moving in from the
west. These clouds were associated with a showrtwave trough
rounding the base of a closed low that was centered over the mid
Mississippi valley. No rain is expected in our CWA until this
evening and then only low chances of light rain across our extreme
northeast. /22/

.DISCUSSION...
Issued at 130 AM CDT Sat Nov 1 2025

Broad cyclonic flow will persist across our entire forecast area
today with mostly quiet conditions.Clouds are beginning to build
from the northwest to the southeast in advance of a digging
cut off upper low. Light showers or drizzle is possible this
afternoon and overnight as the low passes through the region.
Global guidance continues to show a dry cold front pushing through
our CWA tomorrow afternoon, which will help clear any lingering
stratus over our area. A 1024mb sfc high over the Central Plains
will push south and settle over the southeast CONUS along with
building heights aloft Sunday evening. This looks to setup for a
pretty cool night for Sunday night with nighttime lows in the
mid/upper 30s and dewpoints in the 30s. Patchy frost will be
possible across most of our forecast area Sunday night/early
Monday morning.

Shortwave ridging in the wake of this system will yield to a
flattening zonal flow pattern by the middle of the week. Temps
will gradually rebound into the normal range. Rain chances could
return next weekend, but it may be mostly another dry frontal
passage. /NF/
