DISCUSSION
ISSUED AT 202 AM CST SAT DEC 20 2025
THIS IS THE LAST PARTICULARLY COLD MORNING WE'LL HAVE FOR THE
REMAINDER OF THIS FORECAST PERIOD. THANKS TO INCREASINGLY ZONAL
UPPER LEVEL FLOW, THE RIDGE WILL BEGIN SHIFTING EAST OF THE AREA
TODAY, WITH A RETURN TO SOUTHERLY FLOW TONIGHT INTO SATURDAY. THIS
PATTERN WILL PROVIDE ENOUGH MOISTURE FOR SCATTERED LIGHT SHOWERS
BETWEEN LATE TONIGHT AND MONDAY AFTERNOON AS A GLANCING SHORTWAVE
AND WEAK SURFACE FRONT PROVIDE MODEST FORCING. THOUGH RAIN
CHANCES WILL PERSIST OVER MULTIPLE DAYS, BOTH COVERAGE AND
INTENSITY WILL BE LIMITED, AND SOME AREAS MAY RECEIVE NO RAIN AT
ALL. RIDGING WILL BUILD BACK IN EARLY NEXT WEEK, BRINGING A RETURN
TO DRY WEATHER.
AVERAGE TEMPERATURES WILL BE PUSHING ABOUT 15-20 DEGREES WARMER
THAN NORMAL FOR LATE DECEMBER AS WE MOVE INTO THE CHRISTMAS
HOLIDAYS. A WHITE CHRISTMAS IS NOT EXPECTED, BUT SANTA AND HIS
REINDEER MAY ENJOY A MORE TROPICAL EXPERIENCE PASSING THROUGH THE
REGION NEXT WEEK.
AVIATION
(12Z TAFS)
ISSUED AT 500 AM CST SAT DEC 20 2025
VFR FLIGHT CATEGORIES WILL CONTINUE TO PREVAIL AT AREA TAF SITES
THROUGH MUCH OF THE FORECAST PERIOD. AROUND AND AFTER 06Z TONIGHT,
LOW STRATUS WILL BEGIN TO INCREASE ACROSS THE REGION. THIS WILL
RESULT IN FLIGHT CATEGORIES FALLING TO A MIX OF MVFR/IFR
CATEGORIES TOWARD SUNRISE SUNDAY. SOUTH WINDS WILL BECOME
INCREASINGLY BREEZY THROUGH THIS MORNING. BY 18Z, SOUTH WINDS WILL
BE SUSTAINED BETWEEN 10-15 KNOTS, GUSTING TO BETWEEN 20-25 KNOTS
AT TIMES. THIS WILL ESPECIALLY BE THE CASE ACROSS THE DELTA
REGION, I.E. KGLH & KGWO. THESE BREEZY WINDS WILL BEGIN TO SUBSIDE
AROUND SUNRISE THIS EVENING, REMAINING FROM THE SOUTH BETWEEN 3-8
KNOTS THROUGH MUCH OF THE OVERNIGHT HOURS. /19/
