ISSUED AT 134 PM CST MON FEB 23 2026
A FIRE WEATHER WATCH IS BEING ISSUED FOR TUESDAY FOR MUCH OF THE

TEMPERATURES, VERY LOW RELATIVE HUMIDITY (RH), GUSTY SOUTH/SOUTHWEST
WINDS, AND HIGHLY RECEPTIVE FUELS.
BY EARLY TUESDAY MORNING, H850 WINDS VEER WEST/SOUTHWEST AS THE
SURFACE TROUGH DEEPENS ACROSS THE PLAINS. THE 30 TO 40 KNOT LLJ THAT
DEVELOPED OVERNIGHT SHIFTS EASTWARD ON TUESDAY, AND THE LLJ MAXIMA
IS PROG'D TO RESIDE NEAR AND EAST OF THE I-44 CORRIDOR. EXPECT
SOUTH/SOUTHWEST WINDS AT 15 TO 25 MPH AND GUSTS OF 35 TO 40 MPH AS
DAYTIME MIXING TAPS INTO THE LLJ. NOTE THAT THE LIGHTEST WINDS WILL
BE OVER NORTHWEST OKLAHOMA WITH A WIND SHIFT POSSIBLE LATE AFTERNOON
FOR A FEW HOURS AS THE TROUGH AXIS MOVES INTO THAT AREA.
WARMER TEMPERATURES ARE EXPECTED AREA-WIDE ON TUESDAY, WITH ENHANCED
WARMING FROM DOWNSLOPE FLOW ANTICIPATED FROM NORTHWEST OKLAHOMA TO
WESTERN NORTH TEXAS. TEMPERATURES WILL WARM INTO THE UPPER 60'S TO
THE UPPER 70'S. RH WILL BE AS LOW AS 10 PERCENT ACROSS NORTHWEST AND
WESTERN OKLAHOMA INTO WESTERN NORTH TEXAS, AND TO 25 PERCENT ACROSS

A COOLER AND DRIER AIR MASS WITH BREEZY NORTHERLY WINDS IS
EXPECTED IN THE FRONT'S WAKE ON THURSDAY. THE AIR MASS BEHIND THIS
FRONT IS NOT TOO COLD FOR FEBRUARY WITH ABOVE-NORMAL TEMPERATURES
LIKELY TO CONTINUE TO BEHIND IT WITH DOWNSLOPE-WARMING MODIFYING

WINDS RETURN WITH LEE CYCLOGENESIS EAST OF THE ROCKIES.
FORECAST UNCERTAINTY INCREASES MARKEDLY BY THE WEEKEND INTO EARLY
THE FOLLOWING WEEK WITH A LARGE SPREAD AMONG DETERMINISTIC MODELS
AND ENSEMBLE MEMBERS. THERE ARE INDICATIONS THAT A STRONG COLD
COULD POTENTIALLY BE IN CLOSE PROXIMITY TO THE SOUTHERN PLAINS
WITH SIGNIFICANT DIFFERENCES IN THE TIMING OF THE FRONT. AS A
RESULT, PROBABILISTIC GUIDANCE HAS AN ~40 TO 50 DEG F SPREAD
BETWEEN THE 10TH AND 90TH PERCENTILES SUNDAY THROUGH TUESDAY. FOR
NOW, THE TEMPERATURE FORECAST TRENDS COOLER LATE IN THE WEEKEND
INTO EARLY NEXT WEEK WITH THE POTENTIAL TO TREND EVEN COLDER IF
