.DISCUSSION...
Issued at 222 PM CDT Wed Apr 2 2025

Currently, last round of moisture continues across the Northern
Plains this afternoon, as enhanced mid/upper level forcing
associated with the base of the mid level trough and enhanced
left exit region upper jet dynamics are over the region.
Aforementioned forcing, coupled with a continued thermal upglide
flow and an associated TROWAL, will all bring continued light
to moderate snow to eastern and at times central areas of the
state today in the form of wrap around snow. Strong moisture
fetch originating out of the Gulf of America would normally
bring heavier precip/snow amounts, though much of this moisture
will be used up be strong/severe convective activity today
across the Mississippi/Ohio River valleys. Still, areas within
the warning (James River Valley) will see in excess of 6 inches
of snow by the end of this event, with already a few reports of
6-8 inches.

Current system lifts northeast tonight, ending precipitation
from west to east as forcing rapidly decreases. A quasi-zonal
flow aloft will be in place for Thursday, maintaining cooler
temperatures and variable cloud cover. This will then be
followed by a split flow pattern developing Thursday night, with
a northern stream wave bringing another round of light
precipitation (mainly in the form of snow (though some rain
mixed in)) late tomorrow through the day Friday.

After Friday and into next week, confidence is high for dry
weather a warming trend as flow aloft is projected to transition
to upper level ridging allowing mild Pacific air into the Great
Plains region.
