DISCUSSION
ISSUED AT 134 AM EDT THU OCT 9 2025
ISOLATED PATCHY FOG OR LOW CLOUDS THIS MORNING THANKS TO THE
RECENT RAINFALL, BUT MUCH OF THE AREA CURRENTLY LOOKS CLEAR ON
NIGHTTIME SATELLITE IMAGERY AND GUIDANCE DOESN'T APPEAR FAVORABLE
FOR FOG FORMATION, ESPECIALLY WITH THE OVERNIGHT BREEZE. A WEAK
SHORTWAVE WILL BE PASSING THROUGH THE WIDER REGION TODAY, CAMS ARE
SPLIT ON THE IDEA OF A FEW SPRINKLES TO LIGHT RAIN SHOWERS SOUTH
OF SAY SWEETWATER OR ATHENS INTO GEORGIA ASSOCIATED WITH THIS
SYSTEM, NOTHING IMPACTFUL THOUGH. OTHERWISE WE ENTER WHAT APPEARS
TO BE ANOTHER EXTENDED DRY PERIOD.
THE DRIER AIR MASS THAT'S MOVING INTO THE SOUTHERN APPALACHIANS WILL
ALLOW FOR BETTER RADIATIONAL COOLING AT NIGHT WITH LOWER DEWPOINTS,
SO A FEW LOCATIONS IN NORTHEASTERN TN INTO SOUTHWESTERN VA ALONG
WITH THE MOUNTAINS NEXT COUPLE OF MORNINGS MAY SEE SOME 30'S ON
THEIR THERMOMETERS, BUT OTHERWISE THIS IS IN LINE WITH A TYPICAL
OCTOBER. HEADING INTO NEXT WEEK A STRENGTHENING ANOMALOUS RIDGE WILL
BUILD OVER THE LOWER MISSISSIPPI VALLEY AND INCREASE HEIGHTS OVER
US. ENSEMBLE GUIDANCE INDICATES A GENTLE INCREASE IN TEMPERATURES
HEADING INTO NEXT WEEK, WITH THE RIDGE ALSO ALLOWING FOR THE DRY
WEATHER TO CONTINUE. NO SIGNIFICANT WEATHER ON THE HORIZON AS WE
HEAD INTO THE MIDDLE OF OCTOBER.
