DISCUSSION
(TONIGHT THROUGH NEXT TUESDAY)
ISSUED AT 1033 PM CST TUE NOV 11 2025
ELEVATED SOUTHERLY WINDS OVERNIGHT WILL PREVENT LOWS FROM FALLING
BELOW FREEZING BY WEDNESDAY MORNING, WITH LOWS BOTTOMING OUT IN
THE UPPER 30S AND MID 40S. A WARMING TREND WILL BEGIN TODAY AND
WILL PERSIST THROUGH AT LEAST THE FIRST PART OF THE WEEKEND. THE
UPPER LEVEL PATTERN WILL FEATURE A POLEWARD RETREATING JET STREAM
AND SUBTROPICAL RIDGING BUILDING INTO THE LOWER MISSISSIPPI
VALLEY THROUGH LATE WEEK. THERE IS HIGH CONFIDENCE THAT
TEMPERATURES WILL CLIMB SEVERAL DEGREES ABOVE NORMAL ON FRIDAY
AND SATURDAY AS HIGHS PEAK IN THE LOW TO MID 70S.
THE FORECAST BECOMES QUITE UNCERTAIN LATE IN THE WEEKEND, AS
OPERATIONAL SYNOPTIC MODELS STRUGGLE TO RESOLVE THE UPPER LOW
COMING OUT OF SOUTHERN CALIFORNIA ON SATURDAY. THERE IS SOME
AGREEMENT ON A WEAKENING PACIFIC FRONT MOVING THROUGH SATURDAY
NIGHT INTO SUNDAY, BUT THE QPF SIGNAL IS TRENDING DRIER WITH EACH
SUCCESSIVE RUN. TEMPERATURES DO NOT MODIFY MUCH ON SUNDAY WITH
CONTINUED WARMTH.
LREF GUIDANCE SUGGESTS THAT THE UPPER LOW WILL FINALLY EJECT ON
MONDAY, BUT TIMING AND STRENGTH OF THE TROUGH IS STILL A HUGE
QUESTION MARK. THE ECMWF KEEPS THE ENERGY HELD BACK OVER THE
DESERT SOUTHWEST THROUGH MONDAY, WHILE THE GFS IS PROGRESSIVE
WITH THE TROUGH EJECTING INTO THE PLAINS ON MONDAY. THE GFS
SOLUTION PUSHES AN ORGANIZED FRONTAL SYSTEM THROUGH THE MID-SOUTH
EARLY IN THE WEEK WITH COOLER TEMPERATURES AND RAINFALL, WHILE
THE ECMWF DEPICTS A WEAKER, SLOWER SYSTEM CLOSER TO MIDWEEK WITH
CONTINUED WARMTH. WHILE ANY POTENTIAL IMPACTS ARE CURRENTLY
EXPECTED TO BE MINOR, OVERALL CONFIDENCE IS LOWER THAN NORMAL FOR
THIS TIMEFRAME DUE TO THE HIGH INTER-MODEL SPREAD ON THE TIMING
AND STRENGTH OF THE SYSTEM. NBM IS WEIGHTED HEAVIER TOWARDS THE
GFS SOLUTION, WITH SHOWERS AND SCATTERED THUNDERSTORMS RETURNING
TO THE FORECAST MONDAY INTO TUESDAY, BUT CONFIDENCE IS LOW.
