A LOW-AMPLITUDE UPPER TROUGH WILL QUICKLY MOVE ACROSS NEW ENGLAND

PLAINS INTO THE UPPER MS VALLEY THROUGH THE PERIOD. AT THE SFC...A  
STALLED BOUNDARY WILL EXTEND FROM THE MID MS VALLEY SWWD ACROSS KS.  
A POCKET OF MODERATE INSTABILITY IS FORECAST TO REMAIN OVER THE

COOL MIDLEVEL TEMPERATURES WILL EXIST OVER THE REGION WHICH WILL  
COMBINE WITH 50S F DEWPOINTS AND HEATING TO CREATE A MARGINALLY  
UNSTABLE ATMOSPHERE. THE COOL TEMPERATURES ALOFT AND MODEST WLY FLOW

MODERATE DESTABILIZATION WITH MID TO UPPER 60S F DEWPOINTS IN
