A COLD FRONT SOUTH OF THE AREA TODAY. THIS FRONTAL SYSTEM IS
EXPECTED TO STALL NEAR OR JUST SOUTHEAST OF THE MID- ATLANTIC, AND
ADDITIONAL RIPPLES OF LOW PRESSURE RIDING ALONG IT MAY RESULT IN
PERIODIC SHOWERS AND A FEW THUNDERSTORMS AT TIMES THROUGH THE
UPCOMING WEEKEND. HIGH PRESSURE TRACKS IN FROM THE TENNESSEE AND
OHIO VALLEYS EARLY NEXT WEEK WHICH LEADS TO A COOL DOWN. HUMIDITY
VALUES WILL REMAIN HIGH INTO THE WEEKEND, BUT WILL DROP INTO THE

PERIODS IN THE NEAR FUTURE AT THIS TIME.
