ISOLATED RAIN OCCUR. SOUTHWEST VIRGINIA MAY SEE RAIN SHOWERS AS AN
IMPULSE IN THE MID-ATLANTIC TROUGH SWINGS THROUGH WITH UPPER JET
SUPPORT FRIDAY NIGHT. THEN A WEAK SHORTWAVE WILL SLIDE ACROSS THE

FAIRLY ISOLATED THOUGH NEARLY ALL OF THE MEDIUM RANGE GUIDANCE
(INCLUDING THE LONG RANGE CAMS) SHOW A SHOWER OR STORM DURING THE PM
HOURS ON SATURDAY.
COLD FRONT STILL LOOKING TO ARRIVE EARLY NEXT WEEK, BUT ONLY
NEGLIGIBLE RAINFALL EXPECTED. BIGGER THING FROM THE FRONT WILL BE TO
COOL US DOWN TO JUST MILD TEMPERATURES, AND TO IMPART A

WEEK RETURN FLOW, AH, RETURNS AND BEGINS TO SLOWLY RAISE DEWPOINTS
