DISCUSSION

Issued at 154 PM CST Sat Dec 27 2025

near term...Stratus was hanging on this morning and may limit warming over the delta where clouds were pretty solid. Temperatures were rising fast across the south, especially in areas with breaks. Values weren't far off from expected afternoon highs along highway 84 and generally steady near 70 north. Warm southerly winds were also picking up with some occasional gusts. Temps may need to be adjusted. Fog probs have bounced around some, but thinking there will be more fog tonight, especially for the southeast portions of the CWA. At this time, thinking fog will be patchy, so holding off an advisory.

short-term...No changes to the forecast at this time. Still looking for rain to move in Sunday night only generating small amounts of QPF. Winds will be gusting again tomorrow with the strongest winds expected over the western/northwestern zones. Behind the boundary Monday, the gradient will cause widespread windy conditions. Combined with the colder air, especially Monday night, temperatures will feel like the mid teens to lower 20s. If the wind chills fall below 20, the eastern half will fall into dangerous cold.

Temps should be near normal this week, before things warm up next weekend. High pressure settles in after the front and maintains for much of the week. An upper trough passes mid week, but for now stays off the coast. Will have to watch for a shift in the system to see if clouds or any chances are possible Wednesday/Thursday, mainly across the southern zones. The next boundary moves in Friday/Saturday along with some warmer temperatures and a chance for rain.
