DISCUSSION
ISSUED AT 106 PM CDT TUE AUG 25 2026
ELEVATED SHOWERS HAVE BEEN PROGRESSING SOUTHWARD THROUGH THE
REGION THIS MORNING, WITH RAIN MAKING IT TO THE GROUND IN SOME
AREAS. THESE SHOWERS ARE EXPECTED TO CONTINUE SOUTHWARD AND
GRADUALLY DISSIPATE THROUGH THE AFTERNOON. SCATTERED CLOUD COVER
SHOULD REMAIN THROUGH THE AFTERNOON AND ALLOW FOR TEMPERATURES TO
CLIMB INTO THE UPPER 90S AND LOW 100S.
THE RIDGE IS EXPECTED TO PULL BACK SLIGHTLY AND ALLOW FOR A
SHORTWAVE TO RIDE ALONG THE FLOW INTO THE ARK-LA-TX DURING THE DAY
ON WEDNESDAY. THERE COULD ME SOME SHOWER DEVELOPMENT ASSOCIATED WITH
AN MCV ALONG THE I-30 CORRIDOR DURING THE EARLY TO MID MORNING
HOURS. BUT THESE SHOWERS SHOULD BE OVERTAKEN BY THE MAIN SHOW IN THE
LATE AFTERNOON/EVENING HOURS OVER MUCH OF NORTHWEST LA. BOTH ROUNDS
OF SHOWERS HAVE THE POTENTIAL FOR DAMAGING WIND GUSTS, AND A CHANCE
OF FLASH AND URBAN FLOODING FOR OUR FAR EASTERN ZONES. THE SECOND
ROUND OF SHOWERS IS EXPECTED TO PERSIST THROUGH THE OVERNIGHT HOURS
AND EXIT TO THE SOUTHEAST LATE THURSDAY. THE ELEVATED CLOUD COVER
AND SURROUNDING PRECIP COULD VERY WELL IMPACT HOW MUCH AREAS ARE
ABLE TO WARM, AS WE SAW ON MONDAY. AS SUCH, CURRENT CONFIDENCE IS
TOO LOW ON WHAT AREAS WILL STAY CLEAR ENOUGH TO REQUIRE A HEAT
ADVISORY TOMORROW. THE EVENING SHIFT WILL REEVALUATE THIS LATER
TONIGHT.
THE RIDGE SHOULD EXPAND EASTWARD AGAIN AT THE END OF THIS WEEK AND
GOING INTO THE WEEKEND. THIS WILL KEEP TEMPERATURES WARM AND BRING
BACK THE PREVIOUSLY DRY CONDITIONS THROUGH THE REST OF THE FORECAST
PERIOD.
