.KEY MESSAGES...
Updated at 951 AM CST Sat Dec 20 2025

 - A quick warm up expected into the upcoming weekend with highs
   back into the 70`s.

 - Next chance of rain is Sunday, with PoPs in the 30-50% range.
   Intensity will be light, however, with amounts generally
   totaling less than 0.5 inch.

 - Christmas Day is five days out, still on the horizon of our
   forecasting. Right now, though, it is looking warm and dry with
   a reasonable forecast of high temps in the mid to upper 70s.
   At this point, if Santa is checking our forecast, I`m advising
   you wear a hawaiian shirt and flip flops for your Christmas Eve
   visit to our area. ;)

.SHORT TERM...
(This afternoon through Sunday)
Issued at 951 AM CST Sat Dec 20 2025

Tonight through Sunday night, zonal flow will dominate the upper
level pattern. Some patchy dense fog will be possible across the
area Sunday morning, especially for western areas. Looking at the
models, rain chances will be enhanced for Sunday and Sunday
evening (PoPs generally 30-40%). This will mostly present as light
to moderate scattered rain showers. Overall accumulations do not
look noteworthy with most locations seeing 0.5 inches of rainfall
total for tomorrow. No severe weather or flash flooding concerns
are expected with this system. MSW

.LONG TERM...
(Sunday night through Friday)
Issued at 951 AM CST Sat Dec 20 2025

High pressure builds over the area Monday through the rest of the
week. Conditions will be dry overall, as a result. Southerly onshore
flow throughout the week will enhance warm air advection, so
conditions will be unseasonably warm this week as well as humid.
Highs will be in the low to mid 70s at the beginning of the week
with highs in the mid to upper 70s at the end of the week. Some
locations could be approaching 80 degrees Christmas Eve and
Christmas Day. Lows for this week will be in the mid 50s. So,
prepare for a warmer than usual week, but conditions will be dry!
