.SHORT TERM (TONIGHT AND WEDNESDAY)...ISOLATED CONVECTION DEVELOPING
OVER NORTHEAST ZONES...WHERE AIR MASS HAS DESTABILIZED AND A SHORT
WAVE IS MOVING THROUGH.  HOWEVER...MOISTURE IS LIMITED AND MAIN AREA

BECOME QUITE STRONG...POSSIBLY EVEN SEVERE.  CAN NOT COMPLETELY RULE
OUT A STRAY STORM SLIDING INTO THE TN VALLEY...BUT CHANGES ARE LOW
ENOUGH WILL KEEP FORECAST DRY FOR NOW.  ANY STORMS OVER THE AREA
SHOULD DIMINISH QUICKLY WITH SUNSET.  ON WEDNESDAY...WILL SEE
CONDITIONS SIMILAR TO TODAY...WITH AFTERNOON INSTABILITY...MAINLY

REGION.  HOWEVER ...WILL HAVE POPS SLIGHTLY HIGHER AS SHORT WAVE
EXPECTED TO TRACK A LITTLE FURTHER INTO THE MRX CWA.

OF VORTICITY AND INSTABILITY WEDNESDAY, THURSDAY, AND FRIDAY SO HAVE
SLIGHTLY INCREASED POPS IN THOSE TIME PERIODS MAINLY OVER EASTERN
PORTIONS OF FORECAST AREA, IN MOUNTAINS AND HIGHER TERRAIN OF
NORTHEAST. THE LOW FINALLY OPENS UP AND IS ABSORBED BY HUDSON BAY
TROUGH. CENTRAL NOAM RIDGE MOVES EAST ACROSS EASTER U.S. BY LATER
