SHORT TERM
(TODAY THROUGH THURSDAY NIGHT)
ISSUED AT 1132 AM CST TUE DEC 30 2025
THE HIGH PRESSURE SYSTEM ASSOCIATED WITH THE COLD AND DRY CANADIAN
AIR MASS CENTERED OVER NORTHEAST TEXAS WILL CONTINUE TO BUILD AND
SLIDE INTO THE FORECAST AREA THROUGH TONIGHT AND WEDNESDAY. THIS
WILL ALLOW FOR CLEAR SKIES AND MAINLY LIGHT WINDS THAT WILL SET THE
STAGE FOR A VERY CHILLY NIGHT INTO EARLY WEDNESDAY MORNING. A LIGHT
FREEZE ALONG WITH AREAS OF FROST ARE LIKELY FOR A MAJORITY OF THE
FORECAST AREA WITH EXCEPTION RIGHT ALONG THE COAST. WITH VERY LIGHT
TO CALM WINDS, WIND CHILLS WILL BE CLOSE TO ACTUAL AIR TEMPERATURES
AND THEREFORE NO COLD WEATHER ADVISORY WILL BE NEEDED.
THE HIGH PRESSURE SYSTEM WILL MOVE OFF TO THE EAST DURING NEW YEAR'S
EVE NIGHT THAT WILL ALLOW FOR LIGHT SOUTHERLY WINDS TO RETURN AND
WITH THAT A MODERATION AND WARMING IN TEMPERATURES TO BEGIN THE NEW
YEAR.
