DISCUSSION
ISSUED AT 1254 AM CDT TUE JUL 14 2026
THE WEATHER STORY FOR OVERNIGHT TONIGHT AND INTO TOMORROW IS THE
SOURCE OF CONSIDERABLE DISAGREEMENT, DEPENDING ON WHICH MODEL YOU
CONSULT. AS OF THIS WRITING, SHORT RANGE MODELS (HRRR AND NAM 3 KM)
HAVE BACKED OFF CONSIDERABLY, GIVING THE ARKLATEX ONLY VERY ISOLATED
SHOWERS. LONG RANGE MODELS, MEANWHILE, SPECIFICALLY THE ECMWF AND
GFS, CONTINUE TO DEVELOP BROAD AREAS OF SHOWERS, PARTICULARLY ALONG
AND SOUTH OF THE I-20 CORRIDOR, WITH OUR DEEP EAST TEXAS ZONES AGAIN
OUTLOOKED IN A SLIGHT RISK FOR EXCESSIVE RAINFALL LEADING TO FLASH
FLOODING. WHILE COVERAGE AND DEGREE OF IMPACTS MAY BE NOTICEABLY
LESS THAN YESTERDAY, ERRING ON THE SIDE OF CAUTION AND CONTINUING TO
RUN WITH POPS THROUGH THE MIDDLE OF THIS WEEK.
THE UPPER LEVEL LOW OVER THE TENNESSEE VALLEY AND DEEP SOUTH LOOKS
TO RETROGRADE TODAY, PASSING WESTWARD OVER THE ARKLATEX TOMORROW AND
FAVORING FURTHER REDEVELOPMENT OF SHOWERS AND STORMS ACROSS OUR
NORTH EARLY, SPREADING AREAWIDE INTO THE AFTERNOON. AS WAS SEEN
YESTERDAY, THE DEVELOPMENT OF SHORT LIVED SURFACE LOW PRESSURE
CENTERS DURING THE COURSE OF THIS PROPAGATION MAY ADD LOCALIZED
IMPULSES OF ADDITIONAL DEVELOPMENT BEYOND THE SKILL OF MODELS TO
CAPTURE. UNTIL THIS UPPER LEVEL FORCING MECHANISM CLEARS OUR REGION,
SCATTERED HEAVY RAINFALL LEADING TO FLASH FLOODING CANNOT BE RULED
OUT.
BY THURSDAY, THE LOW LOOKS TO HAVE MADE IT TO THE WEST OF THE
ARKLATEX, POTENTIALLY FORMING AN INVERTED TROUGH OVER THE DESERT
SOUTHWEST. SYNOPTIC STRUCTURE ASIDE, THIS SHOULD RESULT IN A RAPID
AND PRONOUNCED DOWNTREND IN OUR PRECIP CHANCES, WITH MOSTLY DRY
CONDITIONS STARTING THURSDAY AND CONTINUING INTO THE WEEKEND AND
THROUGH TO THE END OF THIS EXTENDED FORECAST PERIOD. THE ONLY
EXCEPTION AT THIS TIME IS AN ISOLATED CHANCE OF STORMS ACROSS OUR
WESTERNMOST ZONES THURSDAY AFTERNOON, SEEMING TO RETAIN THE OUTER
IMPACTS OF THE LOW AND FAVORING A SLOWER RETROGRADE. HIGHS IN THE
80S TODAY AND TOMORROW WILL TREND UPWARD INTO THE LOW TO MIDDLE 90S
BY THE END OF THE WEEK AND INTO THE WEEKEND. OVERNIGHT LOWS IN THE
70S WILL CONTINUE THROUGHOUT.

AVIATION
(12Z TAFS)
ISSUED AT 656 AM CDT TUE JUL 14 2026
FOR THE 14/12Z TAF PERIOD, A MIXED BAG OF FLIGHT CATEGORIES TO
BEGIN THE TAF PERIOD, AND EXPECT PATCHY LOW STRATUS AND FOG TO
PERSIST ACROSS MUCH OF OUR AIRSPACE THROUGH MID TO LATE MORNING.
AS A RESULT, EXPECT MVFR/IFR CIGS AND VSBY RESTRICTIONS WITH SOME
ISOLATED IFR/LIFR CONDITIONS BRIEFLY JUST AFTER DAYBREAK. GRADUAL
IMPROVEMENT IS EXPECTED BY LATE MORNING, AND THIS WILL OCCUR AS
CONVECTION IS EXPECTED TO REDEVELOP AND EXPAND ONCE AGAIN AS SFC
HEATING INCREASES THROUGH THE DAY WHILE A FRONTAL BNDRY CONTINUES
TO BISECT OUR AIRSPACE. THEREFORE, HAVE INCLUDED VCSH/VCTS AT
MOST SITES DURING MUCH OF TODAY AND MAY NEED TO PREVAIL TSRA AT
SOME POINT FOR SITES ALONG AND SOUTH OF I-20 IN FUTURE TAF CYCLES
AS CONFIDENCE IN TIMING INCREASES. LIGHT AND MOSTLY VARIABLE WINDS
THIS MORNING WILL PREVAIL THROUGHOUT THE PERIOD WITH THE BNDRY
LINGERING AS SPEEDS AVERAGE BETWEEN 5-10 KTS WITH HIGHER GUSTS
INVOF OF CONVECTION.
