-- Changed Discussion --
ANOTHER QUIET DAY ACROSS THE AREA AS MOSTLY SUNNY SKIES ARE PRESENT ACROSS THE REGION. DRIER WINDS, GENERALLY OUT OF THE NORTH, HAVE HELPED TO KEEP CLOUDS AWAY AND TEMPERATURES JUST A COUPLE OF DEGREES COOLER THAN THEY WERE YESTERDAY. ANOTHER NIGHT WITH TEMPERATURES DROPPING INTO THE 20`S IS EXPECTED OVERNIGHT BEFORE WE WARM UP AGAIN WITH TEMPERATURES IN THE 40`S TO LOW 50`S TOMORROW. WILL LIKELY SEE AN INCREASE IN CLOUD COVERAGE TOMORROW AS HIGHER MOISTURE AIR MOVES IN FROM THE WEST. HOWEVER...NO PRECIPITATION IS EXPECTED. .LONG TERM (SATURDAY NIGHT THROUGH FRIDAY)...THE MAIN STORY FOR THE LONG TERM WILL BE THE AMPLIFICATION OF AN UPPER LEVEL TROUGH OVER THE EASTERN U.S. SUNDAY NIGHT THROUGH TUESDAY WITH A DEEPENING UPPER LOW FORMING ACROSS THE UPPER MIDWEST AND THE NORTHERN OHIO VALLEY. A COUPLE OF SHORT WAVES WILL SHIFT SOUTHEAST ACROSS THE SOUTHERN APPALACHIANS LATER SUNDAY NIGHT INTO MONDAY IN ASSOCIATION WITH THIS AMPLIFYING UPPER LOW. THE EXTENDED PERIOD OF STRONG NORTHERLY FLOW IN THIS REGIME WILL PULL ARCTIC AIR INTO THE DEEP SOUTH LIMITING HIGH TEMPERATURES TO THE 30S ACROSS MOST OF THE FORECAST AREA BOTH TUESDAY AND WEDNESDAY WHILE SOME MODIFICATION OF THE CHILLY AIR IS EXPECTED THURSDAY INTO FRIDAY. A FAIR AMOUNT OF MOISTURE WILL ACCOMPANY THE ARCTIC AIR ON ITS WAY INTO THE EASTERN THIRD OF THE COUNTRY AND THIS SHOULD BE LIFTED INTO A PATTERN OF SNOW SHOWERS ACROSS THE FORECAST AREA LATE SUNDAY NIGHT ALL THE WAY THROUGH WEDNESDAY. IT APPEARS A LIGHT ACCUMULATION IS POSSIBLE IN THE GREAT VALLEY WITH PERHAPS SEVERAL INCHES OF ACCUMULATION IN THE HIGHER TERRAIN DUE TO RELATIVELY STRONG OROGRAPHIC LIFT THROUGH THE THREE DAY PERIOD. GENERALLY IMPROVING WEATHER IS EXPECTED TOWARD THE END OF THE WORK WEEK HOWEVER...PLACED A SLIGHT CHANCE FOR A COUPLE SNOW SHOWERS OR SPRINKLES IN THE MOUNTAINS OF SOUTHWEST VIRGINIA AND EXTREME NORTHEAST TENNESSEE THURSDAY NIGHT INTO FRIDAY WITH THE PASSAGE OF A WEAK WAVE.
