DISCUSSION
(TONIGHT THROUGH NEXT FRIDAY)
ISSUED AT 1157 PM CDT FRI OCT 9 2026
HURRICANE ISAIAS MADE LANDFALL FRIDAY EVENING NEAR DESTIN,
FLORIDA. DRY AIR CONTINUES TO MOVE INTO OUR REGION AS SUBSIDENCE
FROM ISAIAS INFLUENCES OUR WEATHER. AS THE STORM MOVES INTO
TENNESSEE TONIGHT AND SATURDAY, HIGH PRESSURE WILL BUILD IN PLACE,
LEADING TO WARM AND DRY WEATHER FOR THE WEEKEND AND THE START OF
NEXT WEEK.
TO START THE WEEK, AN UPPER-LEVEL RIDGE WILL BUILD OVERHEAD WHILE
HIGH PRESSURE WILL START TO BUILD IN THE EASTERN GULF. THIS WILL
LEAD TO A SOUTHERLY FLOW AND MORE MOISTURE ACROSS THE REGION. WITH
THE WARM TROPICAL AIR MASS, TEMPERATURES WILL ONCE AGAIN RISE INTO
THE LOW 90S ALONG THE COAST AND THE MID 90S FARTHER INLAND. RAIN
CHANCES START TO INCREASE ON TUESDAY AND WEDNESDAY AS MOISTURE
RETURNS TO THE REGION, BUT RAIN CHANCES WILL REMAIN LOW AS THERE
IS NO FORCING TO CAUSE WIDESPREAD RAIN.
