DISCUSSION
ISSUED AT 1220 PM CST SUN JAN 25 2026
ALL PRECIPITATION HAS EXITED THE FORECAST AREA, BUT TEMPERATURES
HAVE BEEN DROPPING THROUGH THE MORNING THANKS TO STRONG COLD AIR
ADVECTION OFF OF THE SLEETPACK/SNOWPACK TO OUR NORTHWEST AND
PERSISTENT STRATUS/STRATOCUMULUS CLOUDS. TEMPERATURES HAVE DROPPED
BELOW FREEZING ACROSS A LARGE PORTION OF THE FORECAST AREA, AND WILL
ONLY WARM UP A TINY BIT DURING THE AFTERNOON. THIS HAS CAUSED SOME
ICY SPOTS ON ROADWAYS EVEN IN AREAS THAT DID NOT RECEIVE FREEZING
RAIN/SLEET AS LINGERING MOISTURE ON ROADWAYS FREEZES. THE WINTER
WEATHER WARNINGS/ADVISORIES HAVE BEEN CANCELLED BUT TRAVEL IMPACTS
WILL REMAIN. TONIGHT, STRONG COLD AIR ADVECTION WILL CONTINUE UNDER
MOSTLY CLOUDY SKIES, WITH LOW TEMPERATURES BEING PURELY ADVECTION
DRIVEN. WHILE TEMPERATURES AND WIND CHILLS HAVE TRENDED UP SLIGHTLY
FOR TONIGHT INTO TOMORROW, THEY REMAIN DANGEROUSLY LOW WITH
TEMPERATURES IN THE TEENS TO LOWER 20S EXPECTED (HARD FREEZE
CONDITIONS) AND WIND CHILLS IN THE SINGLE DIGITS AND TEENS. CONTINUE
TO TAKE ALL COLD WEATHER PRECAUTIONS. ICY PATCHES WILL REMAIN A
CONCERN ON ROADWAYS AS ALL REMAINING MOISTURE RE-FREEZES. TONIGHT
ANOTHER SHORTWAVE MOVES OUT OF WEST TEXAS, BUT THE ASSOCIATED MID-
LEVEL MOISTURE LOOKS TO REMAIN NORTH OF THE FORECAST AREA. CAN'T
RULE OUT A FEW FLURRIES THIS AFTERNOON AND TONIGHT GIVEN THE COLD
AIR MASS AND THE THIN LAYER OF MOISTURE IN THE CLOUD DECK AROUND -
10C BUT NOT ENOUGH FOR ANY IMPACTS.
CHILLY NORTHERLY WINDS CONTINUE ON MONDAY. MODELS HAVE TRENDED A BIT
WARMER WHICH WILL ALLOW FOR MORE OF THE AREA TO REACH ABOVE FREEZING
GIVEN LESS WIDESPREAD ICE ACCUMULATIONS THAN EXPECTED, BUT TEMPS
WILL STILL MAINLY REMAIN BELOW FREEZING UP IN THE BRAZOS VALLEY AND
NORTHERN PINEY WOODS WHERE MORE ACCUMULATION OCCURRED. MONDAY NIGHT
THE CENTER OF AN ALMOST 1040 MB SURFACE HIGH MOVES DIRECTLY
OVERHEAD, RESULTING IN IDEAL RADIATIONAL COOLING CONDITIONS WITH
CALM WINDS. WE ARE STILL LOOKING AT LOWS IN THE TEENS TO LOWER 20S
AGAIN MONDAY NIGHT, AND A FEW COOLER SPOTS UP IN THE PINEY WOODS
WILL PROBABLY REACH THE SINGLE DIGITS. AN EXTREME COLD WARNING
REMAINS IN EFFECT UNTIL TUESDAY. SEE THE CLIMATE SECTION FOR
RECORD LOW TEMPERATURE INFORMATION.
DRY CONDITIONS AND BELOW NORMAL TEMPERATURES ARE EXPECTED THROUGH
THURSDAY WITH PERSISTENT TROUGHING OVER THE CENTRAL AND EASTERN
CONUS. ANOTHER HARD FREEZE IS EXPECTED ACROSS THE PINEY WOODS AND
BRAZOS VALLEY THURSDAY NIGHT. A SOUTHERN STREAM SHORTWAVE APPROACHES
THE AREA BY FRIDAY AND MAY RESULT IN AN AREA OF LOW PRESSURE
DEVELOPING IN THE NORTHWEST GULF ALONG A FRONTAL BOUNDARY. 20-50%
RAIN CHANCES ARE CURRENTLY FORECAST FRIDAY, HIGHEST NEAR THE GULF
COAST. ANOTHER ARCTIC AIR MASS MOVES IN BEHIND THIS SYSTEM FOR THE
WEEKEND WITH CONCERNS FOR ADDITIONAL HARD FREEZES AND LOW WIND
CHILLS. THE PROBABILISTIC WSSI FROM WPC CURRENTLY INDICATES A 10-20%
CHANCE OF AT LEAST MINOR WINTER WEATHER IMPACTS OVER A BROAD AREA OF
THE SOUTHERN CONUS. WE'LL KEEP AN EYE ON IT, BUT THIS IS STILL A
LONG WAY OUT.
