DISCUSSION
(SUNDAY THROUGH NEXT SATURDAY)
ISSUED AT 1129 PM CDT SAT APR 4 2026
WE'VE HAD WAVES OF SCATTERED THUNDERSTORMS ACROSS THE AREA THIS
EVENING, BUT THE MODEST PARAMETER SPACE HAS REALLY STRUGGLED TO
PRODUCE INTENSE OR SUSTAINED CONVECTION. THE ACTIVITY HAS REMAINED
WELL BELOW SEVERE STRENGTH, AND ALREADY MEAGER INSTABILITY WILL
DIMINISH MORE SO AS WE HEAD FURTHER INTO THE EARLY MORNING HOURS.
DESPITE THE OBSERVED WEAKENING TREND, SHORT TERM GUIDANCE
SUGGESTS A COVERING OF MUCH NEEDED RAIN ACROSS THE AREA TONIGHT
ALONG THE COLD FRONT WHICH IS CURRENTLY ORIENTED NORTHEAST TO
SOUTHWEST NEAR THE AL/MS STATE LINE. MOST AREAS COULD PICK UP
AROUND 0.75-1" OF RAIN TONIGHT, BUT THERE WILL BE LOCALIZED
POCKETS OF HIGHER AMOUNTS PERHAPS EVEN UP TO 2", WHILE SOME
RECEIVE SIGNIFICANTLY LESS. FLOODING IS NOT A CONCERN DUE TO THE
PRECEDING DRY CONDITIONS AND OVERALL LIGHT TO MODERATE INTENSITY
OF RAINFALL, BUT THOSE LOCALIZED HIGHER RAINFALL AMOUNTS MAY LEAD
TO PONDING IN LOW-LYING AREAS.
EXPECT THE RAIN TO END AND CLOUDS TO CLEAR FROM WEST TO EAST DURING
THE DAY. THE NORTHWESTERN HALF OF THE AREA SHOULD BE RAIN-FREE BY
MIDDAY, BUT SOME SHOWERS MAY LINGER ACROSS THE SOUTHEAST DURING
THE AFTERNOON. TEMPERATURES WILL BE MUCH COOLER BEHIND THE FRONT
WITH HIGHS THIS AFTERNOON RANGING FROM THE UPPER 60S NORTHWEST TO
MID 70S SOUTHEAST. WE WILL HAVE PLEASANT CONDITIONS AND COOL
NIGHTS THROUGH AT LEAST THE MIDDLE OF THE WEEK AS A BROAD REGION
OF HIGH SURFACE PRESSURE SHIFTS SOUTHEAST ACROSS THE GREAT LAKES
REGION WHILE LOW-LEVEL RIDGING SHIFTS FROM THE SOUTHERN PLAINS
TOWARDS THE SOUTHEAST. THE RIDGE AXIS WILL THEN MOVE TO OUR EAST
AND BEGIN TO ESTABLISH OVER THE WESTERN ATLANTIC. MEANWHILE, A
MID-LEVEL SHORTWAVE TROUGH WILL ROTATE ACROSS THE AREA WEDNESDAY
NIGHT INTO THURSDAY, BUT CHANCES ARE CURRENTLY LOW THAT THERE WILL
BE ENOUGH MOISTURE TO SUPPORT RAIN ACROSS THE AREA. OTHER THAN
THAT, THE FORECAST LOOKS DRY WITH SOME MEASURE OF RIDGING IN PLACE
DOMINATING THE PATTERN THROUGH THE WEEK. LOW-LEVEL FLOW WILL
SHIFT BACK TO THE SOUTH-SOUTHEAST BY THE WEEKEND WHICH WILL
PROMOTE A WARMING TREND WITH HIGHS BACK INTO THE 80S BY SATURDAY.

(00Z TAFS)
ISSUED AT 641 PM CDT SAT APR 4 2026
SCATTERED SHOWERS AND STORMS ARE CURRENTLY AFFECTING OR IN THE
VICINITY OF MOST TAF SITES AT THIS HOUR. ACTIVITY IS GRADUALLY
MOVING TOWARDS THE NORTHEAST WHILE A MORE UNIFORM COVERAGE OF RAIN
AND EMBEDDED TSRA IS NEARING THE AL/MS STATE LINE. EXPECT
AVIATION IMPACTS TO WORSEN OVER THE NEXT SEVERAL HOURS AS THE
WIDESPREAD SHRA MOVES INTO CENTRAL AL AHEAD OF AN APPROACHING COLD
FRONT, PROMPTING IFR CEILINGS TO DEVELOP AREA-WIDE. IFR CONDITIONS
WILL LINGER THROUGH THE MORNING HOURS WITH VFR RETURNING FROM WEST
TO EAST DURING THE DAY AS THE COLD FROM PASSES THROUGH AND CLOUDS
CLEAR. WINDS WILL ALSO SHIFT TO THE NORTHWEST AT ALL SITES BY 18Z
AND WILL REMAIN ELEVATED WITH OCCASIONAL GUSTS OF 15-20 KTS.
86/MARTIN
FIRE WEATHER
WIDESPREAD RAIN WILL GRADUALLY END FROM WEST TO EAST TODAY AS A
COLD FRONT PASSES THROUGH THE AREA. DRIER AIR IN THE WAKE OF THE
COLD FRONT WILL RESULT IN MINRH RANGING FROM 28-40% FOR AT LEAST
THE NEXT FEW DAYS, BUT VALUES ARE CURRENTLY FORECAST TO REMAIN
ABOVE CRITICAL THRESHOLDS. WINDS WILL BE BREEZY AT TIMES WITH
20FT WIND GUSTS UP TO 15 MPH FROM THE NORTH-NORTHWEST TODAY THEN
SHIFTING TO THE NORTHEAST BY TUESDAY.
