ANALYSIS OF WATER VAPOR IMAGERY REVEALS A ROBUST UPPER LEVEL LOW
ENTERING TEXAS THIS EVENING. THE GLM SHOWS NUMEROUS CLOUD FLASHES IN
THE CONVECTION WRAPPING AROUND THIS LOW, WHICH IS EJECTING
NORTHEASTWARD INTO THE FORECAST AREA AS ITS ABSORBED INTO THE MAIN
UPPER LEVEL TROUGH.
IN THE MEANTIME, CONFLUENT MID LEVEL FLOW AT 700 HPA IS SUPPORTING
FRONTOGENESIS TO THE WEST OF THE FORECAST AREA. WIDESPREAD UPPER
LEVEL DIFFLUENCE AND INCREASE POTENTIAL VORTICITY ADVECTION IS ALSO
NOTED. COOLING CLOUD TOPS AND EXPANDING PRECIPITATION WITHIN THE
FRONTOGENETICAL ZONE ARE OCCURRING. MEANWHILE, FAIRLY DEEP
MOISTURE CONTINUES TO STREAM INTO THE AREA FROM THE SOUTH AHEAD OF
THE UPPER LEVEL LOW.
A MID LEVEL WARM NOSE WAS EVIDENT ON THE OUN SOUNDING AT 00Z, WITH
THE 800-700 HPA LAYER AT 0 TO +2 C. AREAS OF SLEET HAVE AND WILL
CONTINUE TO OCCUR AS FAR NORTH AS A LINE FROM OKMULGEE THROUGH
BENTONVILLE, THOUGH THIS LINE SHOULD BEGIN DRIFTING SOUTH WITH
TIME. WITHIN THE SLEET ZONE, THE PHASE MAY CHANGE BACK AND FORTH
DEPENDING ON PRECIPITATION INTENSITY.
CAM GUIDANCE HAD MOSTLY TRENDED DOWN FOR TONIGHT COMPARED TO WHAT
HAD BEEN ADVERTISED. HOWEVER, THE OBSERVATIONAL ANALYSIS
DISCUSSED ABOVE SUGGESTS THAT TONIGHT WILL INDEED PRODUCE
NOTEWORTHY SNOW AND SLEET. IN FACT, RECENT GUIDANCE SHOWS ROBUST
HEAVY SNOW MOVING THROUGH MUCH OF NORTHEAST OK AND SLEET FOR
SOUTHEAST OK AND NORTHWEST AR. THIS SHOULD CONTINUE FOR SEVERAL
HOURS. AREAS OF BANDED SNOW OR SLEET WILL ALLOW CERTAIN CORRIDORS
TO SEE RELATIVELY HEAVIER TOTALS WITH TIME.
DURING THE SECOND HALF OF THE NIGHT, COLDER AIR WILL BEGIN
STREAMING IN ALOFT AND ALL AREAS WILL SWITCH TO SNOW FROM WEST TO
EAST, EVEN IF ONLY BRIEFLY WHEN PRECIPITATION IS WRAPPING UP.
SNOW RATIOS WILL QUICKLY INCREASE OVERNIGHT AS THIS COLDER AIR
WORKS ITS WAY IN, FINALLY ENDING BY LATE MORNING OR EARLY
AFTERNOON. IN TERMS OF OUR UPDATED SNOW AND SLEET TOTALS, ALL OF
THE FACTORS MENTIONED SUGGEST A FAIRLY WIDE RANGE OF
POSSIBILITIES. FOR AREAS THAT SEE SLEET, TOTALS COULD LOCALLY BE
AS HIGH AS 2-3 INCHES. FOR SNOW DOMINANT AREAS, TOTALS COULD BE
AS LOW AS 2-4 INCHES IN SPOTS AND AS HIGH AS 10 INCHES IN OTHERS.
ON AVERAGE, HOWEVER, AN ADDITIONAL 4-8 INCHES CAN BE EXPECTED
WITHIN THE SNOW ZONE. THEN, IN BETWEEN THE SNOW AND SLEET
DOMINANT AREAS, A MIXTURE OF BOTH WILL OCCUR. ROADS ARE ALREADY A
MESS, THIS ADDITIONAL SNOW WILL EXACERBATE EXISTING ISSUES.
TEMPERATURES WILL REMAIN VERY COLD SUNDAY, WITH HIGHS IN THE TEENS
AND LOWS IN THE SINGLE DIGITS FOR MOST LOCATIONS.
LONG TERM
(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 1007 PM CST SAT JAN 24 2026
MONDAY MORNING LOOKS QUITE COLD WITH PARTIALLY CLEARING SKIES,
LIGHT WINDS, AND DEEP SNOW COVER. LOWS WILL FALL TO NEAR OR BELOW
ZERO ACROSS THE AREA. MONDAY AFTERNOON WILL ONLY WARM INTO THE LOW
TO MID 20S.
FOR THE MID WEEK PERIOD, TEMPERATURES WILL ATTEMPT TO MODERATE,
BUT WITH MOSTLY FLAT GRADIENTS AND DEEP SNOW COVER, ANY MODERATION
WILL BE SLOW. HIGH TEMPERATURES WILL RISE INTO THE LOW TO MID 30S
(WARMEST SOUTH) FOR THIS PERIOD, BUT WITH OVERNIGHT LOWS
REMAINING MOSTLY IN THE TEENS. THIS WILL KEEP THE SNOW AND SLEET
MOSTLY IN PLACE, AND ROADS WILL LIKELY REMAIN TRICKY IN MANY
AREAS. ANOTHER SURGE OF ARCTIC AIR ARRIVES FRIDAY, PLUNGING
TEMPERATURES BACK BELOW FREEZING INTO NEXT WEEKEND. THERE IS A
CHANCE FOR SOME ADDITIONAL SNOW AS THE COLD AIR ARRIVES, BUT FOR
NOW ENSEMBLE GUIDANCE SAYS WE ARE MOST LIKELY GOING TO REMAIN DRY.
AVIATION
(06Z TAFS)
ISSUED AT 1055 PM CST SAT JAN 24 2026
PRECIPITATION TYPE REMAINS A CHALLENGE AT MAINLY MLC/FYV/FSM, WITH
ALL SNOW SOLIDIFIED AT THE NE OK TERMINALS AND FAIRLY CERTAIN AT
XNA/ROG. SLEET OR A MIX OF SNOW AND SLEET WILL BE LIKELY AT
MLC/FYV/FSM FOR THE NEXT FEW HOURS BEFORE DEEPER COLD AIR MOVES
INTO THOSE SITES, INITIATING A COMPLETE SWITCHOVER TO SNOW. TIMING
WHEN THAT OCCURS AT EACH SITE CONTAINS A MODERATE LEVEL OF
UNCERTAINTY. WIDESPREAD IFR CONDITIONS WILL CONTINUE THROUGH MOST
OF THE FIRST 12 HOURS OF THE TAF PERIOD AT EACH SITE, WITH A
GRADUAL IMPROVEMENT DURING THE AFTERNOON AND EVENING TOMORROW AS
THE UPPER LEVEL RESPONSIBLE FOR THE WINTRY WEATHER SHIFTS TO THE
NORTHEAST OF THE AREA AND PULLS AWAY.
