DISCUSSION
ISSUED AT 1132 AM CST THU DEC 18 2025
A PRONOUNCED COLD FRONT WILL SWEEP EASTWARD THROUGH THE ARKLATEX
REGION THIS AFTERNOON, WITH GUSTY NORTHWEST WINDS AND DRIER AIR
BUILDING ACROSS THE ENTIRE AREA IN ITS WAKE. AHEAD OF THIS
BOUNDARY, SCATTERED SHOWERS, BROUGHT ABOUT BY WEAK ISENTROPIC LIFT
AND AMPLE LOW LEVEL MOISTURE, WILL LINGER ACROSS THE SOUTHERN
ARKANSAS COUNTIES AND NORTHWEST LOUISIANA PARISHES THROUGH MID
AFTERNOON. RAINFALL AMOUNTS SHOULD BE GENERALLY QUITE LIGHT WITH
THESE SHOWERS, AND MANY LOCATIONS WILL AVOID RAIN ALTOGETHER.
THIS PRECIPITATION SHOULD EXIT THE FORECAST AREA BY 3-4 PM, WITH
CLEARING CONDITIONS BUILDING FROM WEST TO EAST THROUGH THE
AFTERNOON AND EARLY EVENING HOURS.
IN THE WAKE OF THE COLD FRONT, GUSTY NORTHWEST WINDS WILL STEADILY
DIMINISH DURING THE LATE EVENING AND OVERNIGHT HOURS, BUT THE
COMBINATION OF COLD ADVECTION AND EFFICIENT RADIATIONAL COOLING
WILL SEND TEMPERATURES DOWN INTO THE 30S JUST ABOUT EVERYWHERE
ACROSS THE ARKLATEX BY DAYBREAK FRIDAY.
AS THE CANADIAN AIRMASS DOMINATES THE REGION, NEAR AVERAGE SEASONAL
TEMPERATURES WILL PREVAIL ON FRIDAY, WITH 50S AND LOWER 60S COMMON
FOR AFTERNOON HIGHS UNDER SUNNY SKIES. A QUICK WARMUP TO THE 70S WILL
ENSUE SATURDAY AS ZONAL FLOW RETURNS TO THE REGION. THIS WILL BE FOLLOWED
BY A BRIEF INTERLUDE OF INCREASED CLOUDINESS AND WIDELY SCATTERED
SHOWERS SATURDAY NIGHT IN ASSOCIATION WITH A WEAK UPPER LEVEL
DISTURBANCE AND ACCOMPANYING SURFACE COLD FRONT. TEMPERATURES
SUNDAY WILL RETREAT TO THE 60S, BEFORE A BONA FIDE LATE DECEMBER
WARM SPELL ARRIVES TO START CHRISTMAS WEEK. STRONG UPPER LEVEL
RIDGING AND ASSOCIATED SUBSIDENCE ACROSS THE MIDDLE PORTION OF THE
CONUS WILL FACILITATE A STEADY DAY TO TO DAY TEMPERATURE CLIMB
THROUGH THE WEEK. DAYTIME HIGHS WILL TOP OUT WELL INTO THE 70S
EACH DAY, INCLUDING CHRISTMAS DAY, WITH LOWS AREAWIDE MANAGING TO
DIP ONLY INTO THE 50S EACH MORNING. WITH FIRM RIDGING IN PLACE, NO
PRECIPITATION IS EXPECTED THROUGH THE ENTIRE CHRISTMAS WEEK
PERIOD.
