DISCUSSION
(TODAY THROUGH THURSDAY)
ISSUED AT 315 AM CST FRI DEC 20 2024
A DRY AND COOL MORNING IS UNFOLDING ACROSS THE MID-SOUTH, WITH
CURRENT TEMPERATURES GENERALLY SPANNING THE UPPER 30S TO LOW 40S.
CURRENT SATELLITE IMAGERY SHOWS SOME CLOUDS ACROSS MISSOURI,
DRIFTING SOUTHWARD BEHIND A REINFORCING COLD FRONT THAT IS SET TO MOVE
THROUGH THE AREA TODAY. AS THIS BOUNDARY MOVES THROUGH, MANY WILL
LIKELY SEE STAGNANT TEMPERATURES THROUGH THE DAY WITH HIGH
TEMPERATURES IN THE UPPER 30S TO THE NORTH AND MID 40S TO THE
SOUTH. TEMPERATURES WILL QUICKLY FALL TONIGHT UNDER A CLEARING
SKY, WITH WIDESPREAD LOWS IN THE MID 20S. UPPER-LEVEL
NORTHWESTERLY FLOW WILL CONTINUE THROUGH THE WEEKEND, AIDING TO
KEEP DRY CONDITIONS IN THE FORECAST. HIGH TEMPERATURES WILL
GENERALLY REMAIN AT TO BELOW NORMAL, WITH HIGHS IN THE 40S
SATURDAY AND SUNDAY. WEAK UPPER-LEVEL RIDGE WILL DRIFT EASTWARD
ACROSS THE REGION MONDAY, WITH SURFACE FLOW RETURNING TO
SOUTHWESTERLY. AS SUCH, HIGH TEMPERATURES WILL CREEP BACK TO ABOVE
NORMAL, IN THE MID TO UPPER 50S.
SOMEWHAT OF A COMPLEX AND UNCERTAIN WEATHER PATTERN WILL
UNFOLD BY TUESDAY THROUGH THE REMAINDER OF THE NEXT WEEK. AN
UPPER-LEVEL TROUGH WILL BUILD OVER THE PLAINS THROUGH THIS TIME,
WITH GUIDANCE STRUGGLING WITH THE AMPLITUDE AND TIMING OF THIS
SYSTEM. SHORTLY BEHIND, ANOTHER TROUGH WILL MOVE OUT OF THE NW
U.S., LIKELY BRINGING A MORE ACTIVE PATTERN TO THE AREA. GUIDANCE
DOES SUGGEST THAT THE MID-SOUTH WILL BEGIN TO TRANSITION INTO A
WETTER PATTERN BY THE MIDDLE OF NEXT WEEK, BUT WILL NOT GET INTO
EXACT SPECIFICS SINCE THERE ARE STARK DIFFERENCES IN MODEL
SOLUTIONS. WITH THIS BEING SAID, THE CHRISTMAS HOLIDAY IS
TRENDING IN A WET DIRECTION, WITH HIGH TEMPERATURES LIKELY JUST
ABOVE NORMAL FOR THE END OF DECEMBER IN THE MID 50S.

CLOUDS ARE NOTED ON SATELLITE ACROSS WEST TENNESSEE AND NORTH
MISSISSIPPI. THESE ARE THE RESULT OF A WEAK DISTURBANCE MOVING
