.DISCUSSION...
Issued at 144 PM CDT Sun Mar 15 2026

...Synopsis...

Skies are clearing this afternoon across much of the region
with the main cloud shield associated with the winter storm over
the upper midwest still lingering in our southeastern zones.
Winds will remain gusty for the next 12 hours, so blowing snow
impacts may arise, particularly in the southern portions of the
area where the freshest snowpack is. Impacts should greatly
improve after 00z as gusts die down and sustained winds slowly
diminish. Cold temperatures will be left in its wake with
overnight lows falling below zero in some locations. We`ll see
another cold day tomorrow before we start to warm up with highs
in the single digits to teens.

The upper flow pattern will feature an anomalously large ridge
over the southwestern United States, bringing extreme heat to
the southwest and putting us in northwesterly flow aloft. There
will be a very fast moving shortwave that brings a nice swath of
warm air advection snow across the area. Generally the QPF
footprint is modest, generally a few tenths. The bulk of
precipitation appears to be on the cold side of the thermal
ridge so primarily snow will be the concern, although given the
close proximity of it some freezing rain may mix in. This
creates a roughly 60% chance for advisory impacts due to
freezing rain and snow.

The ridge continues to build through the remainder of the week
with the potential for temperatures to rise into the 60s by
Friday before we get another shot of precipitation. Overall,
expect a relatively quieter week with Tuesday being the main
risk for weather impacts.

Issued at 1128 PM CDT Sun Mar 15 2026

VFR conditions as most of the clouds have cleared out. Some
signs of stratocu development tomorrow, although not much
consistency between models on exact coverage and ceiling height.
For now have SCT-BKN at 3500 to go middle of the road for the
time being. Winds from the north to northwest continue to lose
their gusts overnight, then pickup again with gusts to over 20
kts in some locations tomorrow afternoon. Winds will become
light and variable towards the end of the period.
