..NEW UPDATE
KEY MESSAGES

- WELL ABOVE NORMAL HIGHS MIDWEEK, SLIGHT COOLDOWN AFTER A
FRONTAL PASSAGE SOMETIME SATURDAY INTO SUNDAY.

UPDATE
ISSUED AT 228 AM CST TUE DEC 9 2025
LATEST OBSERVATIONS ACROSS THE REGION HAVE SHOWN TEMPERATURES
HAVE FALLEN TO NEAR FREEZING FOR MANY LOCATIONS AND DEW POINTS ARE
RUNNING LOWER THAN PREVIOUSLY FORECAST IN THE 20S ACROSS MANY
LOCATIONS. THIS SHOWS THAT THE TEMPERATURES STILL HAVE ROOM TO
LOWER WITH THE VERY EFFECTIVE RADIATIONAL COOLING WITH THE CLEAR
SKIES AND CALM WINDS. AS A RESULT, WE HAVE ELECTED TO ISSUE A
FREEZE WARNING FOR MOST COUNTIES EXCEPT FOR THOSE THAT ARE CLOSEST
TO THE RIO GRANDE, WHERE WARMER TEMPERATURES WILL RESIDE.
COUNTIES THAT ARE TO THE NORTH OF THE FREEZE WARNING HAVE HAD A
WIDESPREAD FREEZE ALREADY THAT ENDED THE FREEZE WARNING PROGRAM IN
THOSE LOCATIONS FOR THIS COOL SEASON ALREADY.
SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 1201 AM CST TUE DEC 9 2025
BY SUNRISE EARLY THIS MORNING WE COULD SEE A FEW SPOTS FLIRT WITH
THE FREEZING MARK AS STRONG RADIATIONAL COOLING HAPPENS
OVERNIGHT. AS SUCH WE HAVE DECIDED TO ISSUE AN SPS FOR THIS
POSSIBILITY FOR THE OVERNIGHT PERIOD. WE SHOULD WARM UP NICELY AND
BY MIDDAY TUESDAY SURFACE WINDS RETURN TO A MORE SOUTHWESTERLY
DIRECTION ALLOWING FOR A BOOST TO TEMPS BACK ABOVE NORMAL WITH
MANY AREAS IN THE MID TO UPPER 60S POSSIBLY APPROACHING 70 IN A
FEW SPOTS. AS THE HIGH PRESSURE MOVES OFF TO THE EAST MODELS HAVE
BEEN HINTING AT A SURFACE BOUNDARY WASHING OUT ACROSS OUR AREA BY
EARLY TO MIDDAY WEDNESDAY. AS SUCH LOWS OVERNIGHT INTO WEDNESDAY
WILL REMAIN MILD WITH MANY AREAS REMAINING IN THE LOW TO MID 40S.
ADDITIONALLY, HIGH TEMPS HAVE BEEN DIALED BACK AS THIS BOUNDARY
CAUSES A SHIFT IN WINDS BACK TO THE NORTH NORTHWEST. EXPECT HIGH
TEMPS TO TOP OUT IN THE LOW TO MID 70S IN THE EAST WHERE THE
BOUNDARY WILL WASH OUT WITH MID TO UPPER 70S ACROSS THE WEST.
LONG TERM
(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 1201 AM CST TUE DEC 9 2025
AS WE MOVE INTO THE LONG TERM EXPECT A SLIGHTLY COOLER NIGHT FOR
WEDNESDAY EVENING AS NORTHERLY WINDS CONTINUE TO ALLOW FOR SOME
ADVECTIVE COOLING OVERNIGHT. HOWEVER, WE ARENT LOOKING AT ANY
FREEZE POSSIBILITY AS MOISTURE WILL ACTUALLY BE ON THE INCREASE
HEADING INTO THURSDAY MORNING THUS LIMITING THAT POTENTIAL. EXPECT
MUCH MORE MILDER TEMPS TO CONTINUE FOR THURSDAY ALBEIT IT A TOUCH
COOLER DUE TO THE SLIGHT DELAY IN SOUTHERLY FLOW. LOW LEVEL
SOUTHERLY FLOW RETURNS AND REALLY RAMPS UP ALLOWING HIGHS TO SOAR
INTO THE UPPER 70S TO NEAR 80 BY FRIDAY AND POSSIBLY INTO SATURDAY
AS WELL. LOWS DURING THIS PERIOD WILL ALSO BE MUCH MORE MILD WITH
MANY AREAS STAYING IN THE UPPER 40S TO MID 50S. OUR NEXT FRONT
THEN APPROACHES SOMETIME AROUND LATE SATURDAY AS THE FRONT LOOKS
TO COME IN MUCH SLOWER NOW AS PREVIOUSLY THOUGHT. IT STILL LOOKS
TO REMAIN RAIN FREE LIKE THE FRONT THAT MOVED THROUGH THIS PAST
SUNDAY AND BRINGS WITH IT A SLIGHTLY COOLER AIRMASS TO THE AREA
FOR SUNDAY. THE LATEST RUNS OF THE NBM CONTINUE TO SHOW
CONSIDERABLE UNCERTAINTY REGARDING THE TIMING AND STRENGTH OF THIS
FRONT. REGARDLESS, EXPECT VERY MILD AND DRY WEATHER THROUGH
SUNDAY. TEMPS BEHIND THIS FRONT ALSO LOOK TO DROP BACK DOWN TO
MORE SEASONABLE LEVELS WITH HIGHS RETURNING TO THE LOW 60S. BEYOND
SUNDAY, MODEL ENSEMBLES ARE HINTING AT THE POSSIBILITY OF SOME
RAIN CHANCES HOWEVER THIS IS STILL VERY FAR AWAY AND THINGS COULD
CHANGE.
