DISCUSSION
ISSUED AT 202 AM EDT SAT NOV 1 2025
CURRENTLY EARLY THIS MORNING, TROUGHING IS TO OUR NORTHWEST WITH
HIGH PRESSURE REMAINING IN PLACE. AFTER A COOL MORNING, THIS TROUGH
WILL DEEPEN THROUGHOUT THE DAY WITH FRONTOGENESIS TAKING PLACE NEAR
THE OHIO RIVER VALLEY. THE REGION WILL REMAIN DRY AND SEASONALLY
COOL THROUGHOUT THE DAY. HOWEVER, THESE FEATURES WILL APPROACH THE
REGION WITH INCREASING MOISTURE BY THE EVENING HOURS, BRINGING A
RETURN OF RAIN CHANCES. THESE CHANCES WILL CONTINUE INTO SUNDAY AS
AN UPPER LOW BECOMES CUT OFF OVER THE REGION. TEMPERATURES AT OR
BELOW 850MB WILL STAY ABOVE FREEZING EARLY ON BUT WILL DROP SLIGHTLY
ON SUNDAY. SOME OF THE HIGHEST PEAKS COULD SEE A MIX WITH LIGHT
SNOW, BUT LITTLE TO NO ACCUMULATION IS ANTICIPATED OUTSIDE OF PLACES
LIKE MOUNT LECONTE. OVERALL, RAIN TOTALS LOOK TO BE LIGHT AS PWATS
WILL STAY WELL BELOW 1 INCH BUT STILL SUFFICIENT FOR MOST PLACES TO
SEE RAIN.
BY MONDAY, THE CLOSED LOW WILL SHIFT WELL OFF TO OUR EAST WITH HIGH
PRESSURE EXPANDING FROM THE SOUTH AND WEST, BRINGING A RETURN OF DRY
CONDITIONS. HEIGHTS WILL GRADUALLY RISE THROUGH THE WEEK WITH
LINGERING HIGH PRESSURE KEEPING RAIN CHANCES OUT OF THE AREA. A
GRADUAL WARMING TREND CAN BE EXPECTED WITH TEMPERATURES RISING BACK
ABOVE NORMAL BY THE SECOND HALF OF THE WEEK. BY FRIDAY, HIGH
PRESSURE WILL SHIFT EAST OF THE REGION WITH ANOTHER TROUGH DEEPENING
TO OUR WEST. A LOT IS UNKNOWN ABOUT THE EVOLUTION, BUT RAIN CHANCES
OF 20 TO 30 PERCENT WILL RETURN BASED ON THE CONSENSUS OF A SYSTEM
DEVELOPING AND MOVING INTO THE EASTERN U.S.
