FOUR STATE REGION THROUGH THE WEEKEND, RESULTING IN POWER
OUTAGES AND IMPOSSIBLE TRAVEL CONDITIONS.

DISCUSSION
ISSUED AT 1200 AM CST SAT JAN 24 2026
OUR HIGHLY ANTICIPATED WINTER STORM IS UNDERWAY AS WHAT STARTED AS
RAIN IS QUICKLY TRANSITIONING OVER TO A MIX OF SLEET AND FREEZING
RAIN ACROSS THE I-30 CORRIDOR. ARKANSAS DOT CAMERAS NEAR AND
AROUND THE TEXARKANA AREA SHOW SLEET COVERED HIGHWAYS AS A RESULT
OF HEAVIER BANDS OF PRECIP JUST BEFORE MIDNIGHT. AT THE SAME TIME,
REPORTS OF ICE ON ELEVATED SURFACES AND CARS HAVE COME IN THROUGH
THE EVENING IN AREAS ALONG AND NORTH OF I-30. THIS COLD ARCTIC
AIRMASS WILL CONTINUE TO SPILL SOUTHWARD, AS TEMPERATURES AT OR
JUST BELOW FREEZING WILL BEGIN TO EMERGE ALONG THE I-20 CORRIDOR
WELL BEFORE DAYBREAK. THIS WILL ALLOW THE LIGHT REFLECTIVITY
RETURNS ON RADAR, WHICH HAVE BEEN PREDOMINANTLY RAIN TO THIS
POINT, TO TRANSITION TO A FREEZING RAIN MIX, WITH THE CHANCE FOR
SLEET IN HIGHER REFLECTIVITY RETURNS. A 12Z WEATHER BALLOON LAUNCH
IS SCHEDULED FOR LATER THIS MORNING. THIS LAUNCH WILL SAMPLE THE
ENVIRONMENT AS THE SUB-FREEZING SURFACE TEMPERATURES CONTINUE TO
SLIDE SOUTH THROUGH DAYBREAK. EXPECTATION IS FOR A ROBUST WARM
NOSE TO STILL BE PRESENT ALOFT, WHICH WILL CONTINUE TO SUPPORT THE
FORECAST OF FREEZING RAIN THROUGH THE DAY, RESULTING IN DANGEROUS
TRAVEL CONDITIONS AND IMPACTFUL ICE ACCUMULATIONS ACROSS THE
REGION. GIVEN THE EXPECTATION FOR IMPACTFUL ICE ACCUMULATION AND
PROLONGED IMPACTS, AN ICE STORM WARNING WAS ISSUED THIS AFTERNOON
FOR AREAS ALONG AND SOUTH OF THE I-20 CORRIDOR, WHERE CONFIDENCE
IS HIGHEST FOR PREDOMINATELY ICE DURING THE WEEKEND EVENT.
RADAR IMAGERY WILL LIKELY BE SPLIT BY THREE DIFFERENT P-TYPES
THROUGH THE AFTERNOON AS IT WILL STILL TAKE SOME TIME FOR A
COMPLETE CHANGEOVER FROM RAIN TO WINTER MIX ACROSS THE FAR
SOUTHERN PARISHES AND COUNTIES. AS A RESULT, IMPACTS TO THE FAR
SOUTHERN ZONES WILL BE LIMITED THROUGH THIS FIRST INITIAL WAVE,
WITH CHANGES EXPECTED AS THE SECONDARY WAVE OF FORCING AND PVA
MAX MOVES INTO THE AREA LATE SATURDAY AND INTO SUNDAY MORNING. BY
THIS POINT, SUB-FREEZING TEMPERATURES WILL BE AREAWIDE AS WE ENTER
A PERIOD OF HEAVIER PRECIP RATES, WHICH CAN RESULT IN QUICK ICE
AND SLEET ACCUMULATIONS BASED ON LOCATION. AT THE SAME TIME, CAMS
CONTINUE TO SUGGEST ROBUST CONVECTION WITHIN THIS WAVE OF PRECIP,
WITH THE ODDS OF THUNDER WITHIN THE HEAVIER BANDS OF PRECIP ON THE
HIGHER SIDE. HI-RES GUIDANCE CONTINUES TO SUGGEST THAT PRECIP
WILL EXIT THE REGION DURING THE AFTERNOON, WITH THE CHANCE THAT A
FEW SNOW SHOWERS/FLURRIES LINGER ACROSS THE AREA THROUGH LATE
SUNDAY.
WHILE THE DEPARTURE OF THE PRECIP WILL BE A WELCOMED SITE, IN THE
WAKE OF THE WINTER STORM, BITTERLY COLD TEMPERATURES WILL
CONTINUE TO LINGER INTO BOTH MONDAY AND TUESDAY MORNING. MORNING
LOWS WILL SIT IN THE SINGLE DIGITS AND LOW TEENS, WITH WIND CHILL
VALUES NEAR AND BELOW ZERO. TEMPERATURES WILL FINALLY CLIMB ABOVE
FREEZING BY TUESDAY AFTERNOON, ALLOWING FOR THE THAW PROCESS TO
GRADUALLY BEGIN. WITH THIS EXPECTED, THIS WOULD CAP OFF ALMOST
80-90 HOURS BELOW FREEZING FOR SOME LOCATIONS. THAT BEING SAID,
WHILE HIGHS WILL BE ABOVE FREEZING, OVERNIGHT LOWS WILL FALL TO
NEAR OR JUST BELOW FREEZING, ALLOWING FOR SOME BACK AND FORTH
PERIODS OF REFREEZE THROUGH THE MIDDLE TO END OF NEXT WEEK.
NOW IS THE TIME TO STAY INDOORS AND AVOID ALL TRAVEL AS ROAD
CONDITIONS WILL ONLY DETERIORATE FROM HERE AS TEMPERATURES
CONTINUE TO FALL AND PRECIP COVERAGE EXPANDS.

(18Z TAFS)
ISSUED AT 1129 AM CST SAT JAN 24 2026
WE HAVE BEEN SEEING LOTS OF LIGHT TO MODERATE FREEZING RAIN AND
SLEET MIX SO FAR THIS MORNING ALONG AND NORTH OF THE INTERSTATE
TWENTY CORRIDOR (TYR/GGG/SHV/TXK/ELD/MLU) THIS MORNING WITH MORE
OF A FREEZING RAIN AND RAIN MIX SOUTH OF THIS AXIS - ALTHOUGH
MAINLY JUST RAIN WITH TEMPERATURES JUST ABOVE FREEZING AT LFK.
EXPECTING THE MAIN FIRST ROUND OF PRECIPITATION TO EBB FROM WEST
TO EAST THIS AFTERNOON, ALTHOUGH NOT ENDING ENTIRELY BEFORE THE
NEXT WAVE COMES IN TONIGHT. RATES OF FREEZING RAIN (AND AT LEAST
SOME SLEET ALONG AND NORTH OF I-20) SHOULD INCREASE AGAIN THIS
EVENING THROUGH MIDNIGHT FROM WEST TO EAST WITH ACCUMULATION
POTENTIAL IN ALL AREAS AS ALL AREAS SHOULD BE BELOW FREEZING.
PRECIPITATION WITH THIS FINAL ROUND WILL CLEAR OUT FROM WEST TO
EAST FROM MID MORNING TOMORROW THROUGH EARLY AFTERNOON, ALTHOUGH
LOW CLOUDS WILL LIKELY NOT CLEAR OUT ENTIRELY UNTIL MONDAY.
OTHERWISE, ANTICIPATE MOSTLY A MIX OF IFR AND LIFR CONDITIONS
THROUGH THE TAF PERIOD WITH SOMEWHAT GUSTY NNE SURFACE WINDS
THROUGH THIS EVENING GRADUALLY LESSENING AND CHANGING TO MORE FROM
THE NW BY MID MORNING TOMORROW. FINALLY, EXPECT MAINLY MVFR
VISIBILITIES THROUGH TOMORROW, ALTHOUGH VISIBILITIES WILL DROP IN
FURTHER DURING BOUTS OF HEAVIER PRECIPITATION. /50/
