KEY MESSAGES

- Areas of dense fog are likely to develop later tonight across parts of North Texas. - Near to below normal temperatures will continue through Monday, with above normal temperatures expected the rest of next week.

SHORT TERM

(Tonight through Sunday) Issued at 1203 AM CST Sat Dec 6 2025

Late evening satellite imagery shows a continued stream of high cloud cover extending across central Mexico and into Texas. This is courtesy of a 140 kt upper jet tapped into Pacific moisture on the east side of an elongated trough axis draped across the central CONUS. While the cloud cover has been thick, the sub cloud layer is fairly dry resulting in precipitation free conditions. With the upper trough still to our west, modest forcing for ascent will continue to overspread the region tonight, however a lack of appreciable moisture will keep any rain from developing. At the surface though, a weak area of low pressure is noted over west- central TX. Ahead of this low pressure, light east-southeast winds have developed and dewpoints have steadily climbed into the upper 30s and lower 40s. With air temperatures just a few degrees warmer, areas of fog are beginning to develop with slight reductions in visibility noted over the last hour. Thick high cloud cover will inhibit optimal radiational cooling and may work against a sharp reduction in visibility initially, but continued moisture advection into North Texas should allow areas of dense fog to develop through the early morning hours. This is most likely to occur along and north of I-20 where the best combination of cooler air and thinner cloud cover will reside. The current Dense Fog Advisory will remain unchanged at this time.

As an initial shortwave embedded within the overall trough axis spreads east today, cloud cover will thin and any fog will erode through late morning. Low clouds may linger across parts of the northeast into early afternoon, but most areas should see some clearing by late in the day. As a result of the clouds/fog, we'll see high temps remain in the mid 50s across the north and east while clearing will promote temps in the upper 60s across our southwest. Another upstream shortwave will approach the area later tonight and will drag a cold front through the region early Sunday. Areas of fog may again develop late tonight ahead of the front primarily across our eastern counties. North winds along with cooler and drier air will spill southward into the region through the day Sunday where highs will generally remain in the 50s.

LONG TERM

(Sunday night through next Friday) Issued at 1203 AM CST Sat Dec 6 2025

A quiet weather pattern is expected through much of next week as the upper flow becomes amplified with troughing to our east and ridging to our west. Most of the Southern Plains will be beneath a dry northwest flow aloft through the week. After a cool start to the week with highs in the 50s on Monday, we'll see steadily climbing temperatures Tuesday through Thursday with highs approaching the mid 70s in some areas Thursday afternoon. Another cold front is expected on Friday but looks to come through dry at this time.

AVIATION

(06Z TAFS) Issued at 1203 AM CST Sat Dec 6 2025

Thick high cloud cover continues to stream across the region tonight with VFR cigs/vis prevailing for another few hours. A light east-southeast wind will continue to pull moisture into the region and areas of fog are still expected to develop late tonight into early Saturday morning. We've made some minor tweaks to the TAF forecast with this package and will show MVFR vis by 10Z with a TEMPO for IFR vis/cigs from 12-15Z. Low cigs may linger through late morning with a sharp improvement expected after midday. VFR should prevail this afternoon and for much of tonight, although we'll be watching the potential for some MVFR cigs to spread southward late Saturday night into early Sunday morning behind a cold front.
