BRIEFLY EXPECTED DURING THE DAY SATURDAY, BUT ONLY BETWEEN
37-45F.
SATURDAY NIGHT, WE'LL SEE THE COLDEST READINGS ASSOCIATED WITH
THIS AIRMASS WITH THE SURFACE HIGH SITUATED JUST TO OUR NE. WITH
LIGHTER WINDS AND CLEAR SKIES, READINGS SHOULD FALL INTO THE
18-33F RANGE AND SLIGHTLY LOWER WIND CHILLS. SUSPECT MOST OF OUR
REGION WILL SEE A HARD FREEZE (TEMPS AT OR BELOW 24F FOR 2+ HOURS)
SO WENT AHEAD AND HOISTED A FREEZE WATCH FOR ALL EXCEPT LOCATIONS
CLOSEST TO THE COAST. MOST OF THEM TOO WILL SEE A FREEZE, BUT
PROBABLY NOT DOWN TO 24F.
SUNDAY, RIDGING WILL GRADUALLY MOVE OFF TO THE EAST. SOUTHEAST FLOW
OFF THE GULF WILL RESUME AND BRING SOME GRADUALLY WARMER TEMPS AND
MOISTURE BACK INLAND AS WE GET INTO EARLY NEXT WEEK.
ELONGATED MID/UPPER TROF OFF BAJA LOOKS TO KICK OUT AND TRACK
EASTWARD ACROSS TX LATE MON. IF WE HAVE ENOUGH MOISTURE RECOVERY BY
