DISCUSSION
ISSUED AT 135 AM CDT SAT MAY 23 2026
THE WARM FRONT AND ASSOCIATED SFC LOW THAT BROUGHT US RAIN ON
THURSDAY HAS MOVED NORTH OF THE REGION. HOWEVER, ISOLATED TO
SCATTERED THUNDERSTORMS DEVELOPED YESTERDAY EVENING ACROSS EAST
TEXAS AND NORTH LOUISIANA ALONG A CONVERGENCE ZONE NEAR THE I-20
CORRIDOR. SOME OF THOSE STORMS WERE STRONG ENOUGH TO PROMPT SEVERE
THUNDERSTORM WARNINGS, AS WELL AS FLASH FLOOD WARNINGS DUE TO
THEIR SLOW MOVEMENT. THAT CONVECTION HAS DIMINISHED, BUT
ADDITIONAL ISOLATED SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP
AT THIS HOUR ACROSS NORTH LOUISIANA FROM REMNANT OUTFLOW
BOUNDARIES FROM THE EARLIER CONVECTION. SHORT-TERM PROGS CONTINUE
THIS THROUGH THE OVERNIGHT PERIOD, BEFORE A COMPLEX OF STORMS MOVE
INTO OUR AREA THIS MORNING IN ASSOCIATION WITH A STRONG SHORT-
WAVE DISTURBANCE MOVING ALONG THE ESTABLISHED SOUTHWEST FLOW UPPER
PATTERN IN PLACE. MODELS ARE BRINGING THE COMPLEX ACROSS OUR EAST
TEXAS ZONES ALONG AND NORTH OF I-20 AROUND DAYBREAK. BUT,
ADDITIONAL CONVECTION IS EXPECTED DURING THE LATE MORNING AND
AFTERNOON HOURS AS THE SHORT-WAVE TROUGH MOVES INTO THE REGION.
LOCALLY HEAVY RAINFALL AND LOCALIZED FLOODING WILL BE POSSIBLE
WITH THESE STORMS, ESPECIALLY SINCE WE HAVE SATURATED SOILS IN
PLACE FROM RECENT RAINFALL. A FLOOD WATCH IS ALREADY IN EFFECT FOR
MOST OF OUR EAST TEXAS AND LOUISIANA ZONES SOUTH OF I-20, BUT I
WOULDN'T BE SURPRISED IF WE NEED TO EXTEND IT NORTHWARD, AS THOSE
AREAS HAVE RECEIVED DECENT RAINFALL OVER THE PAST FEW DAYS.
FROM SUNDAY THROUGH ALL OF NEXT WEEK, A COUPLE OF UPPER-LEVEL
TROUGHS WILL MOVE INTO THE SOUTHERN PLAINS, RESULTING IN DAILY
MULTIPLE ROUNDS OF SHOWERS AND THUNDERSTORMS. THE CURRENT FLOOD
WATCH WILL REMAIN IN EFFECT THROUGH AT LEAST MONDAY EVENING, BUT
COULD BE EXTENDED THROUGH NEXT WEEK, AS THE ELEVATED FLOOD RISK IS
LIKELY TO REMAIN. THE THREAT FOR ORGANIZE SEVERE WEATHER WILL
STILL REMAIN LOW, BUT AN ISOLATED STRONG TO SEVERE THUNDERSTORM
CAN'T BE RULED OUT DURING THIS PERIOD. /20/
