12/25 – Payton’s Christmas Evening Forecast

High pressure over the Mid South will slide east through tomorrow.
Flow will become more easterly but dewpoint readings will hover in
the 20s across the north and 30s across the southern zones. Upper
level winds aloft revealed a northwest flow from the to the
Mississippi Valley. An inverted trough will develop along the
old frontal boundary over west gulf Tuesday through Wednesday.
Moisture will increase across along the Texas coast tonight
through Tuesday. However, moisture aloft will increase over
Southeast Texas and eventually south half of Louisiana Tuesday
afternoon through Wednesday. Overrunning pattern will persist
and rain and clouds will act to limit daytime highs to the 40s and
50s during the mid week period, with the exception of some 60s
across coastal areas of southeast Louisiana. Dry conditions will
return for the end of the week, but rain chances will go up once
again for the last half of the weekend as another cold front moves
toward the area. There is a chance we could see freezing temperatures to start the new year, but it is too soon to know for sure. Stay tuned as we get a better idea of how the forecast will play out.
