SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 1143 PM CST SAT DEC 6 2025
A BROAD UPPER TROUGH COVERED MUCH OF THE EASTERN TWO THIRDS OF THE
COUNTRY THIS EVENING, WITH RIDGING ALONG THE PACIFIC COAST. QUASI-
ZONAL FLOW WAS NOTED ALONG THE NORTHERN GULF COAST AHEAD OF A
SHORTWAVE NEAR THE TEXAS BIG BEND AREA. AT THE SURFACE, HIGH
PRESSURE EXTENDED FROM KENTUCKY TO GEORGIA. FRONTAL BOUNDARIES
WERE WELL TO THE SOUTH OVER THE CENTRAL GULF, AND WELL TO THE
NORTH NEAR INTERSTATE 70. PATCHY LIGHT RAIN WAS NOTED OVER THE
LOWER PORTIONS OF THE LOUISIANA COASTAL PARISHES. LOW CLOUDS WERE
COVERING MUCH OF THE AREA WITH TEMPERATURES MAINLY IN THE LOWER
AND MIDDLE 50S WITH LIGHT EASTERLY WINDS.
THE SOUTHERN STREAM SHORTWAVE OVER THE BIG BEND AREA WILL SHIFT
EASTWARD AND BE MOVING OFF THE GEORGIA COAST SUNDAY EVENING. A
STRONG NORTHERN STREAM SHORTWAVE WILL DIG INTO THE BASE OF THE
TROUGH OVER THE APPALACHIANS BY MONDAY. LOW PRESSURE ASSOCIATED WITH
THE SOUTHERN STREAM SHORTWAVE MAY BRIEFLY TURN WINDS SOUTHEASTERLY
DURING THE DAY SUNDAY, ALLOWING TEMPERATURES TO WARM TO NEAR 70
SUNDAY AFTERNOON. AS THE SHORTWAVE AND LOW PASS EAST OF THE AREA
SUNDAY NIGHT, WINDS WILL SHIFT TO THE NORTH AND MUCH COOLER AND
DRIER AIR WILL ARRIVE LATE SUNDAY NIGHT AND MONDAY. SCATTERED
SHOWERS AND PERHAPS A FEW STORMS COULD ACCOMPANY THE FRONT. LIKELY
TO SEE SOME SUNSHINE BY MONDAY AFTERNOON, BUT GUSTY NORTHERLY WINDS
WILL MAKE IT FEEL COOLER THAN IT LOOKS.
TEMPERATURES AREN'T LIKELY TO MOVE MUCH PRIOR TO SUNRISE SUNDAY.
TEMPERATURE SOLUTIONS FOR THE MOST PART ARE PRETTY CLOSE TO THE
ECMWF GUIDANCE THROUGH MONDAY. WON'T ENTIRELY RULE OUT A FREEZE
ACROSS NORTHERN AREAS EARLY TUESDAY MORNING, BUT NOT SPECIFICALLY
FORECASTING IT AT THIS POINT.
LONG TERM
(TUESDAY THROUGH SATURDAY NIGHT)
ISSUED AT 1143 PM CST SAT DEC 6 2025
WITH THE LONGWAVE TROUGH AXIS TO OUR EAST FOR THE MIDDLE OF THE
WEEK, THE UPPER FLOW WILL BE NORTHWESTERLY, WHICH SHOULD KEEP THE
AREA DRY THROUGH AT LEAST THURSDAY. IF THERE IS GOING TO BE ANY
PRECIPITATION DURING THIS PORTION OF THE FORECAST, IT WILL PROBABLY
BE THURSDAY NIGHT AND/OR FRIDAY MORNING AS A NORTHERN STREAM
SHORTWAVE PASSES WELL TO THE NORTHEAST OF THE AREA, DRAGGING A COLD
FRONT ACROSS US.
TUESDAY WILL BE CHILLY UNTIL THE SURFACE HIGH AXIS PASSES TO THE
EAST OF THE AREA. WEDNESDAY AND THURSDAY WILL BE THE WARM DAYS FOR
THE WEEK, APPROACHING 70 WEDNESDAY AND WELL INTO THE 70S ON
THURSDAY. COLDER AIR WILL ARRIVE AGAIN ON FRIDAY, WITH HIGH
TEMPERATURES SATURDAY AND SUNDAY OF NEXT WEEKEND LIKELY NOT
GETTING OUT OF THE 50S, IF THAT WARM, WITH A FREEZE POSSIBLE LATE
SATURDAY NIGHT.
