Found part of Jeff's thoughts on the front and on what we may be looking forward to weather wise for Thanksgiving
Strong cold front will cross the region this evening…ending the mild sunny weather.
Front currently located in the southern panhandle moving SE around 30mph. Behind the boundary temps. have fallen into the 30’s with NW winds of 25-35mph while ahead of the front shallow Gulf moisture is returning to the area. Upstream temps. over the great plains are in the teens and 20’s…so some decent cold air is pooling behind this front.
Extrapolation of frontal movement places the boundary into the CLL area around 600pm this evening and off the upper TX coast by 1100pm to midnight. Moisture return today will be shallow and models only suggest a thin line of showers with the boundary mainly south of I-10. Of bigger notice will be the onset of strong NW winds and much colder temps.
Shallow cold air mass will be overrun by moist WSW flow above the surface Friday resulting in cloudy and cold conditions under strong cold air advection regime. Expect highs to remain in the 50’s. Isentropic pattern really gets going Saturday into Sunday resulting in cloudy and cold conditions on Saturday with a slight chance of drizzle or light rain and highs mainly in the 50’s. Warm front should cross the region on Sunday ahead of a deeper storm system slated for Monday. Gulf air mass should regain control through Monday night ahead of the next front. Moisture looks deeper and more plentiful with this system leading to a better chance of rain Sunday afternoon into Monday night. Front should clear the area early Tuesday with sunny and cool to mild weather for the middle to end of next week.
Long range models show a vigorous storm system moving into S CA toward the middle of next week with potential effects on TX the day after Thanksgiving into that weekend.
