THE ATMOSPHERE ALONG AND WEST OF HIGHWAY 281 WAS WORKED OVER PRETTY
WELL, AS WAS PORTIONS OF THE HILL COUNTRY EAST OF 281. ALONG I-35 THE
STORMS RAN OUT OF STEAM QUICKLY AND LEFT BEHIND JUST A GENTLE
MODERATE RAIN WHILE NOT AS MUCH OF A COOL AND GUSTY OUTFLOW. WE IN
OUR PERIOD OF FORECASTING ARE THUS STUCK ON THE FENCE BETWEEN A
RESURGENT MCS OVERHEAD GAINING BACK STEAM AS IT MOVES EAST OVER SE TX
OR FURTHER WEAKENING AS NEW DYNAMIC LIFT REPLACES THE MCVS AND
GENERATES A MIDDAY HEAVY RAIN EVENT. WHILE THE CURRENT POPS IN THE
DAY 1 PERIOD REFLECT A VERY WET PERSISTENT RAIN THREAT, IT'S MORE
LIKELY THAT THE LEAD MCV WILL MOVE SLOW ENOUGH FOR THE RESURGENT
CONVECTION TO GET GOING OVER THE COASTAL PRAIRIES BEFORE SUNRISE AND
DRAG A REVITALIZED LINE OF STORMS INTO EAST TX, LEAVING OUR MIDDAY
HOURS WITH ONLY SOME ISOLATED, PERHAPS ELEVATED STORMS. THUS OUR
EMPHASIS ON TODAYS HEAVY RAIN POTENTIAL TIMING WILL SHIFT BACK TOWARD
THIS EVENING, BUT THE TIGHT POSITION OF THE SLOW MOVING LOW JUST
NORTH OF THE AREA SHOULD PROMOTE AT LEAST A THREAT OF DAYTIME HEAVY
RAIN, ESPECIALLY NEAR AUS AND AREAS TO THE NORTH. SAN ANTONIO, WHILE
GETTING A FAIR SHARE OF RAIN IN REGARDS TO MONTHLY AVERAGES,
CONTINUES TO GET CHEATED ON THE DROUGHT RELIEF RAIN THAT CONTINUES TO
CATCH OUR NORTHERN COUNTIES. THIS HOPEFULLY CHANGES TONIGHT, BEFORE
THE H5 LOW CENTER BEGINS TO SHIFT FOCUS TOO FAR EAST.
THE SPC SLIGHT RISK AREA SEEMS TO FIT THE MORE PROGRESSIVE TREND OF
THE MORNING MCVS SHOWING A STRIPE OF HIGHER RISK RUNNING WEST TO EAST
ALONG I-10 WHERE DAMAGING WINDS/HEAVY RAIN WILL PROBABLY BE THE MAIN
THREATS. THE NEXT ROUND, WHENEVER IT BEGINS WILL PROBABLY HAVE MORE
CAPABILITY TO ADD SOME POCKETS OF LARGE HAIL THREATS AS NEW AND
DISCRETE CELLS CLOSER TO THE UPPER LOW DYNAMICS AND WITH A LOWER
PWAT ENVIRONMENT. HIGHEST POPS AROUND SAN ANTONIO ARE THUS
CONCENTRATED FROM 06Z TO 18Z THURSDAY AFTER THE NEXT ROUND OF SLOW-
MOVING STORMS ARE FULLY CONGEALED INTO A COMPLEX. NEEDLESS TO SAY,
EVEN IF YOU DON'T ENJOY THE THUNDER AND HEAVY RAIN, THE NEXT COUPLE
DAYS WILL GIVE US A WELCOME BREAK FROM THE STRING OF HOT DAYS WE HAD
OVER THE PAST WEEK.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 239 AM CDT WED JUN 11 2025
MODEL CONSENSUS DEPLETES THE AREA OF THE GOOD DYNAMICS AS THE UPPER
LOW CROSSES NORTH TX TOWARDS AR/LA FRIDAY. THERE WILL BE SOME
RESIDUAL INSTABILITY IN THE NW/N FLOW ALOFT BEFORE UPPER RIDGING
TAKES BACK OVER. THE PATTERN IS LOOSE, SO THE FINAL NIGHT OF
NOCTURNALLY FAVORED CONVECTION COULD BE SATURDAY OR AS LATE AS
MONDAY. THE MORE LIKELY POPS THAT THE NBM CLINGS TO IS THE COASTAL
PRAIRIES DIURNAL CONVECTION. DEPENDING ON IF WE GET THE NOCTURNAL
ROUNDS, THE WARMING TREND BACK TO HOT & HUMID DAYTIME TEMPS WILL BE
IMPACTED AS WELL. THE CURRENT FORECAST REFLECT WESTERN COUNTIES
RETURNING TO SUMMER-LIKE HEAT BY FRIDAY, AND EASTERN COUNTIES
RETURNING BY EARLY NEXT WEEK.

THE FOCUS FOR THIS FORECAST WILL BE ON THE POTENTIAL FOR CONVECTION
DEVELOPING LATE THIS AFTERNOON/EARLY EVENING INTO EARLY THURSDAY
MORNING. FOR NOW, CONFIDENCE IS A LITTLE HIGHER FOR THE LATE
EVENING/EARLY THURSDAY MORNING PERIOD AND WILL INCLUDE TEMPO GROUPS
FOR TSRA FOR THE I-35 SITES. WE COULD SEE SOME ISOLATED CONVECTION
DEVELOP THIS AFTERNOON, BUT WILL NOT MENTION IN THE FORECAST DUE TO
EXPECTED ISOLATED COVERAGE.
