KEY MESSAGES

Updated at 508 PM 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! MSW

AVIATION

(00Z TAFS) Issued at 508 PM CST Sat Dec 20 2025

MARINE

Issued at 951 AM CST Sat Dec 20 2025

Southerly light (5-10kt) wind conditions hold through the remainder of the weekend. As we move through the week a strong dome of high pressure dominates and we see easterly winds at 5-10 kt. Beginning Tuesday, we see wave heights at 3-4 ft in the offshore waters. MSW
