-- Changed Discussion --
(TONIGHT AND FRIDAY)...SURFACE HIGH PRESSURE WAS CENTERED OVER THE OHIO VALLEY THIS AFTERNOON. NORTHEASTERLY WINDS WERE GENERALLY LIGHT AND TEMPERATURES WERE GENERALLY IN THE 70S AND 80S. A FEW ISOLATED SHOWERS WILL BE POSSIBLE FOR PARTS OF THE APPALACHIANS. A MOSTLY CLEAR NIGHT ON TAP ALONG WITH CALM WINDS SHOULD ALLOW FOR GOOD RADIATIONAL COOLING AGAIN TONIGHT. THERE MAY BE PATCHY FOG THAT DEVELOPS CLOSER TO SUNRISE IN PARTS OF SW NC AND SW VA AND NE TN. FRIDAY IS SHAPING UP TO BE A NEAR CARBON COPY OF TODAY...HOWEVER IT WILL BE A COUPLE OF DEGREES WARMER FOR ALL LOCATIONS. THERE COULD STILL BE A FEW ISOLATED SHOWERS ALONG THE SPINE OF THE MOUNTAINS TOMORROW BUT CONFIDENCE IS RATHER LOW. .LONG TERM...(TOMORROW NIGHT THROUGH THURSDAY)... THE DRY PATTERN WILL START SEEING CRACKS IN THE ARMOR STARTING AS EARLY AS TOMORROW NIGHT AS MOIST SOUTHERLY FLOW RETURNS AND A UPPER LEVEL TROUGH MOVES TOWARDS OUR AREA. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL BE AROUND THE AREA DURING THE AFTERNOONS. CURRENTLY LOOKS LIKE THE BEST COVERAGE WILL LIKELY BE ON SUNDAY. MODELS START TO DIVERGE WITH THE STRENGTH OF THE RIDGE AND LINGERING MOISTURE OVER THE AREA. WILL STICK WITH SLIGHT CHANCES ON AND OFF THROUGH THE REST OF THE FORECAST, BUT OVERALL LOOKS TO BE RELATIVELY DRY FOR MOST PEOPLE MOVING INTO NEXT WEEK.
