DISCUSSION
(TONIGHT THROUGH NEXT FRIDAY)
ISSUED AT 1121 PM CDT FRI SEP 25 2026
THE 00Z UPPER-AIR ANALYSIS SHOWED AN UPPER-LEVEL LOW LOCATED OFF
THE MID-ATLANTIC COAST, AN UPPER-LEVEL TROUGH OFF THE WEST COAST,
WITH AN UPPER-LEVEL RIDGE PRESENT IN BETWEEN THESE TWO FEATURES
ACROSS THE LOWER MISSISSIPPI VALLEY. THIS RIDGE RESULTED IN DRY
AND PLEASANT CONDITIONS ACROSS THE MID-SOUTH WITH LATE EVENING
TEMPERATURES IN THE 70S. CONFIDENCE REMAINS HIGH FOR DRY WEATHER
THROUGH EARLY NEXT WEEK AND LOWER CONFIDENCE IN TIMING OF RAIN
CHANCES TOWARDS THE LATTER HALF OF NEXT WEEK.
THIS UPPER-LEVEL RIDGE WILL REMAIN IN PLACE THROUGH EARLY NEXT
WEEK, BRINGING A CONTINUATION OF DRY WEATHER TO THE AREA. HIGHS
THIS WEEKEND WILL BE MOSTLY IN THE 80S WITH A FEW LOCATIONS IN
EAST ARKANSAS AND NORTHWEST MISSISSIPPI APPROACHING 90 DEGREES.
TEMPERATURES WILL FALL BACK INTO THE 50S AND 60S AT NIGHT. LOWER
DEWPOINT AIR WILL MITIGATE OVERNIGHT FOG DEVELOPMENT AND RESULT
IN COMFORTABLE AFTERNOONS DESPITE THE WARM TEMPERATURES.
LATEST ENSEMBLE AND DETERMINISTIC MODEL RUNS INDICATE THE UPPER-
LEVEL RIDGE WILL GRADUALLY BREAK DOWN TOWARDS THE MIDDLE OF NEXT
WEEK AS A CUTOFF UPPER-LEVEL LOW DEVELOPS NEAR CALIFORNIA AND THE
FUTURE REMNANTS OF HURRICANE POLO CONSOLIDATE AND MOVE TOWARDS
THE SOUTHERN PLAINS AND PORTIONS OF THE LOWER MISSISSIPPI VALLEY.
NBM RAIN CHANCES HAVE DECREASED SLIGHTLY AS THE ECMWF HAS BEEN
TRENDING A BIT SLOWER THAN THE GFS AND CANADIAN SOLUTIONS. A
LARGE SPREAD IN GEFS MID-LEVEL HEIGHTS EXISTS WITH SUBSEQUENT
RAIN CHANCES NEEDING ADDITIONAL ADJUSTMENTS DEPENDING ON THE
EVENTUAL TRACK OF THIS LOW.
