(TONIGHT THROUGH SATURDAY)...HIGHER PRESSURE WITH A SLIGHTLY DRIER AND COOLER AIR MASS WAS SETTLING OVER THE FORECAST AREA THIS AFTERNOON. A FEW SHOWERS WERE FORMING JUST EAST OF THE APPALACHIAN CREST...JUST EAST OF THE FORECAST AREA. OVER EAST TENNESSEE...SOUTHWEST NORTH CAROLINA AND SOUTHWEST VIRGINIA SKIES WERE PARTLY CLOUDY GENERALLY WITH TEMPERATURES IN THE 80S TO ALMOST 90. OVER THE NEXT 24 HOURS NOT MUCH CHANGE IN OVERALL PATTERN BUT DRIER AIR MASS WILL CONTINUE TO ADVECT IN THE OHIO VALLEY AND MID ATLANTIC. EXPECTING DEW POINTS TO DROP A FEW DEGREES SATURDAY AND UPPER RIDGE WILL BUILD EAST AS WELL. HIGHS SHOULD WARM A COUPLE DEGREES FOR SATURDAY WITH HIGHS IN THE MID 80S TO NEAR 90 IN THE NORTHEAST AND LOWER TO MID 90S CENTRAL AND SOUTHERN VALLEYS. PATCHY FOG...LOCALLY DENSE NEAR THE WATERWAYS WILL LIKELY FORM TONIGHT. .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)...RIDGE OF HIGH PRESSURE WILL GENERALLY REMAIN OVER THE CENTRAL TO EASTERN HALF OF THE UNITED STATES THROUGH MUCH OF THE LONG TERM FORECAST, WHICH WILL LEAD TO GENERALLY SUPPRESSED RAIN CHANCES FOR TODAY`S FORECAST. WE WILL FINISH OUT THE WEEKEND DRY BEFORE MORE MOISTURE MOVES INTO THE AREA BRINGING US SOME SLIGHT CHANCES OF RAIN THROUGH THE REST OF THE FORECAST. STILL LOOKS LIKE AREAS IN THE NORTHERN PART OF THE CWA, GENERALLY I-40 AND NORTH, HAVE THE BEST CHANCES TO SEE SHOWERS AND THUNDERSTORMS IN THE UPCOMING WORK WEEK. AT THIS POINT, LOOKS LIKE SOME OF THE BEST RAIN CHANCES ON THE HORIZON WILL BE AT THE TAIL END OF THE FORECAST PERIOD INTO NEXT WEEKEND AS THE RIDGE GET`S SHOVED AWAY AND A FRONTAL BOUNDARY LOOKS TO STALL NEAR THE AREA. OF COURSE, WITH THIS SYSTEM BEING SO FAR OUT MODEL DISCREPANCIES ARE HIGHER THAN I WOULD LIKE. BUT AT THIS POINT IT LOOKS LIKE NEXT WEEKEND COULD BE CLOUDY AND WET.
