...SYNOPSIS...
ONTARIO UPPER VORTEX WILL BEGIN TO EDGE SLOWLY EWD ON SUNDAY...WHILE
SRN STREAM REMAINS ENTRENCHED ACROSS THE SRN TIER OF THE COUNTRY. 
MID LEVEL WLY WINDS ACROSS THE SRN U.S. AND NWLY WINDS OVER THE
NRN/CENTRAL PLAINS WILL RESULT IN CONFLUENCE ALOFT AND LARGE SURFACE
HIGH PRESSURE TO COVER MUCH OF THE NATION. THIS WILL MAINTAIN A
COOLER AND DRIER AIR MASS ACROSS MOST OF THE COUNTRY WITH MUCH BELOW
NORMAL CONVECTIVE ACTIVITY FOR EARLY MAY. THE HIGHEST PROBABILITIES
FOR THUNDERSTORMS WILL BE ACROSS THE FL PENINSULA AS A COLD FRONT...
CURRENTLY MOVING EWD THROUGH THE ATLANTIC COASTAL STATES...MOVES SWD
ACROSS THAT REGION ON SUNDAY.

...CNTRL/SRN FL PENINSULA...
BAND OF TSTMS ALONG AND SOUTH OF THE COLD FRONT ARE EXPECTED TO BE
ONGOING AT THE START OF THE PERIOD ACROSS THE CENTRAL FL PENINSULA. 
STORMS ARE LIKELY TO INTENSIFY BY MIDDAY AS DIURNAL HEATING RESULTS
IN MUCAPE VALUES AROUND 1500 J/KG. HOWEVER...DEEP LAYER SHEAR WILL
NOT BE PARTICULARLY STRONG AND THE LOW LEVEL JET IS FORECAST TO BE
LOCATED WELL EAST OF THE PENINSULA. THIS SUGGESTS WEAK LOW LEVEL
CONVERGENCE AND ONLY A MINIMAL SEVERE WEATHER THREAT.

...SRN ROCKIES/GREAT BASIN AND PACIFIC NW...
MID LEVEL MOISTURE WILL PERSIST ACROSS THE REGION INTO SUNDAY AND
WITH DAYTIME HEATING...MARGINAL INSTABILITY AND LIFT NEAR HIGHER
TERRAIN SHOULD SUPPORT A FEW THUNDERSTORMS DURING THE
AFTERNOON/EARLY EVENING HOURS.
