PERSISTENCE FORECAST FOR THE NEXT SEVERAL DAYS, AND MOST OF THE
NEXT WEEK AS THE SURFACE AND LOWER LEVELS OF THE ATMOSPHERE
REMAIN MOSTLY UNDER HIGH PRESSURE WITH RIDGING TRYING TO BUILD IN
FROM THE WEST FURTHER UP IN THE ATMOSPHERE.
THIS WILL LEAD TO CONTINUED PLEASANT WEATHER DAYS WITH MOSTLY CLEAR
SKIES, LIGHT WINDS, AND TEMPERATURES RIGHT AROUND SEASONAL NORMALS.
HAVE MADE A FEW TWEAKS TO DEW POINTS AND INCLUDED PATCHY FOG IN THE
RIVER VALLEYS AS WE'VE SEEN THE PAST SEVERAL MORNINGS... BUT
OTHERWISE THIS IS A LOW IMPACTS FORECAST FOR THE SOUTHERN
APPALACHIANS AND EASTERN TENNESSEE VALLEY.
INCREASED CLOUDS COULD MOVE IN NEXT WEEK AS A TROUGH SWINGS THROUGH
TO OUR NORTH, BUT AS OF THIS WRITING NO PRECIPITATION IS
ANTICIPATED.
