DEEP UPPER TROUGH OVER THE ERN HALF OF THE NATION WILL SHIFT EWD TO
THE ERN SEABOARD AND DEAMPLIFY BY SUNDAY MORNING...AS A VIGOROUS
SHORTWAVE TROUGH DIVES SEWD FROM SASKATCHEWAN INTO THE UPPER
MIDWEST. ALTHOUGH AN OCCLUDED SURFACE LOW IS FORECAST TO MOVE NEWD
FROM PA INTO NEW ENGLAND ON SATURDAY...SURFACE COLD FRONT SHOULD
MOVE OFFSHORE EARLY IN THE PERIOD...WITH MOST OF THE COUNTRY COVERED
BY A DRY AND STABLE AIR MASS. THE EXCEPTION WILL BE ACROSS THE SRN
FL PENINSULA WHERE THE COLD FRONT WILL MOVE OFFSHORE BY 18Z.
HOWEVER...WINDS ARE FORECAST TO VEER TO WLY AHEAD OF THE FRONT AND
SURFACE CONVERGENCE SHOULD PRECLUDE THUNDERSTORM DEVELOPMENT ALONG
FRONT. IN NEW ENGLAND...THE BOUNDARY LAYER WILL BE COLD WITH
TEMPERATURES IN THE 20S AND 30S...BUT STRONG ISENTROPIC LIFT OF
ATLANTIC MOISTURE MAY RESULT IN SUFFICIENT INSTABILITY FOR ELEVATED
CONVECTION. FORECAST SOUNDINGS INDICATE THE DEPTH OF THE BUOYANT
LAYER SHOULD NOT SUPPORT MORE THAN AN ISOLATED LIGHTNING STRIKE OR
TWO.
