SHORT TERM
(THROUGH SATURDAY)
ISSUED AT 1042 PM CST FRI DEC 5 2025
A BAND OF MID CLOUD SWEEPING ACROSS THE REGION IN ADVANCE OF AN
UPPER WAVE SHOULD CLEAR THE REGION BY DAYBREAK SATURDAY. CLEARING
SKIES WILL ALLOW THE COOL AND RELATIVELY MOIST AIRMASS IN PLACE TO
RADIATE OUT AND FOG UP. THE HREF/HRRR HAVE SHOWN CONSISTENT
SIGNALS FOR DENSE FOG OVER A GOOD PORTION OF E OK AND FAR NW AR.
AN ADVISORY WILL BE ISSUED FROM MIDNIGHT TO 11 AM SATURDAY. WITH
TEMPS NEAR FREEZING IN SOME SPOTS, WILL NEED TO WATCH FOR THE
POTENTIAL FOR FREEZING FOG, THOUGH THIS POTENTIAL APPEARS TO BE
LOW WITH DEWPOINTS OVER MUCH OF THE REGION NEAR OR ABOVE FREEZING.
THE FOG AND LOW CLOUD WILL PROBABLY BE SLOW TO ERODE LIKE IT WAS
TODAY. FOLLOWED THE LEAD OF THE PREVIOUS SHIFT AND KEPT HIGH TEMP
FORECAST SEVERAL DEGREES BELOW THE MODEL BLEND (NBM).
LACY
LONG TERM
(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 1042 PM CST FRI DEC 5 2025
A COLD FRONT WILL SWEEP SOUTHEAST ACROSS THE REGION SATURDAY NIGHT
INTO SUNDAY, BRINGING GUSTY NW WINDS AND CONTINUED BELOW AVERAGE
COOL CONDITIONS. PRECIP CHANCES WITH THIS SYSTEM SHOULD STAY TO
THE NORTH AND EAST OF THE FORECAST AREA CLOSER TO THE SURFACE LOW
PRESSURE AND SHORTWAVE TROUGH ALOFT. A BANK OF LOW CLOUD IS
LIKELY TO SURGE INTO THE AREA FROM THE NORTH BEHIND THE FRONT AND
MAY BE TOUGH TO GET RID OF. LIKE SATURDAY, WENT A FEW DEGREES
BELOW NBM FOR FORECAST HIGHS SUNDAY, BUT A WARMING TREND WILL GET
GOING MONDAY.
THE BROAD UPPER TROUGH OVER THE EASTERN 2/3RDS OF THE COUNTRY THIS
WEEK WILL SHIFT EAST NEXT WEEK. DOWNSLOPE FLOW WILL BRING A SHARP
WARMUP STARTING TUESDAY, WITH ABOVE AVERAGE WARMTH EXPECTED TO
PERSIST THROUGH THURSDAY. MOST OF THE ENSEMBLE FORECAST SCENARIOS
AS WELL AS THE LATEST DETERMINISTIC DATA SUGGEST THAT THE NEXT
FRONT WILL ARRIVE BY THURSDAY NIGHT, WITH MUCH COOLER TEMPS ON THE
WAY FOR FRIDAY.
THE LACK OF UPPER TROUGHING TO OUR WEST IN THIS UPPER PATTERN
PRECLUDES MUCH IN THE WAY OF PRECIPITATION CHANCES FOR OUR AREA
OVER THE NEXT 7 DAYS.
