.MESOSCALE UPDATE...
Issued at 957 PM CST Sat Dec 21 2024

An axis of surface high pressure extends from the Ohio River
Valley southwestward across our area tonight. There is a little
bit of light wind as we aren`t squarely under the core of this
high, but where winds are calm expect temps to radiate quickly
under clear skies. Overnight low temps were nudged colder toward
typical cooler bias-corrected guidance, with those temps at
sunrise around the mid 20s at most locations Sunday morning. This
is in range of current dew point values, so it seems reasonable.
In some locations, temps could radiate colder than current dew
point values, and patchy freezing fog can`t be ruled out. This is
typically in the river drainages, so be careful in areas of fog
near any bridges. Low-level adiabatic descent will accompany high
pressure in the region tomorrow, and afternoon RH could mix down
to around 25-30 percent. /NF/

.DISCUSSION...
Issued at 258 PM CST Sat Dec 21 2024

Remainder of the weekend: Cold surface high pressure will have
the greatest influence on weather for the Lower MS Valley region
this weekend. Dry and seasonably cold conditions (~5 to 10 F below
normal) with freezing overnight temperatures can be expected.

Monday through Christmas Eve: Dry weather will continue, but
expect temperatures to moderate significantly with the upper level
flow becoming more zonal and Pacific in origin while surface winds
become more southeasterly.

Christmas Day through the end of the week: A series of mid
latitude shortwave troughs will traverse the nation and impact the
forecast area. As the surface warm sector increases with each
approaching trough, it is possible that severe weather may become
a concern, especially as we go into Fri/Sat, so be sure to monitor
for updates. /EC/
