.SHORT TERM...
CONVECTION HAS BEEN RELATIVELY SLOW TO GET GOING THIS
AFTERNOON...BUT HOURLY SPC MESOANYLYSIS STILL SHOWS VERY GOOD
DESTABILIZATION GOING ON WITH DAYTIME HEATING.  HAVE EXPANDED
MENTION OF THUNDERSTORMS TO ALL THE FORECAST AREA UNTIL AROUND
MIDNIGHT TONIGHT...WITH ENHANCED CONVECTIVE WORDING OVER NORTHERN
AND CENTRAL PORTION OF THE AREA.

FRONTAL PASSAGE TONIGHT HELPS SHUT DOWN CONVECTIVE THREAT...
BRIEFLY...BEFORE FLOW TURNS BACK AROUND TO THE SW AND WE GET ANOTHER
SHOT AT CONVECTION TUE NIGHT.  ANOTHER FRONTAL PASSAGE ON WEDNESDAY
USHERS US INTO A SOMEWHAT COOLER...DRIER AND LESS CONVECTIVELY
ACTIVE PERIOD.

&&

.LONG TERM...
FORECAST GETS INTERESTING AGAIN AS WE ROLL INTO THE MEMORIAL DAY
WEEKEND PERIOD.  FRONTAL BOUNDARY...WHICH NCEP PROGS CURRENTLY KEEP
TO OUR SOUTH ON SUN AND MON...WILL PLAY A KEY ROLE IN OUR WEATHER
PATTERN.  DID NOT GET TOO GLOOMY WITH FORECAST...AND KEPT TEMPS AND
POPS NEAR SEASONAL NORMS FOR THE WEEKEND.  FINAL POSITION OF FRONT
WILL DETERMINE WHAT HAPPENS.

&&

.MARINE...

WINDS AND SEAS ARE GENLY EXPECTED TO REMAIN BELOW SCA CRITERIA
THROUGH THE FORECAST PERIOD, WITH THE POSSIBLE EXCEPTION THAT SEAS
WED NEAR SANDY HOOK MAY INCREASE TO NEAR 5 FT IN A MODERATE S FLOW.

SW OR WSW WINDS WL GENLY PREVAIL INTO THIS EVENING, AND WINDS ALG
THE NRN MONMOUTH COUNTY COAST WERE IN THE PROCESS OF COMING ARND TO
THE S FM ONSHORE. FRONTAL BOUNDARY PASSES LATER TNGT WITH ASSOCIATED
WIND SHIFT, BUT W WINDS TUE SHOULD GO BACK TO SW LATE IN THE DAY AND
IN THE EVENING AS A STRONGER COLD FRONT APPROACHES FROM THE W. THAT
FRONT WILL CROSS THE MARINE AREA WED NIGHT, AND WINDS WILL SHIFT TO
THE NW. WINDS WILL SHIFT AGAIN BACK TO THE S AND SW THU NIGHT INTO
FRI.

...A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EVENING ACROSS THE ENTIRE REGION...

THERE IS A SLIGHT RISK OF SEVERE WEATHER THIS AFTERNOON AND EVENING.
DAMAGING WINDS AND LARGE HAIL ARE THE MAIN CONCERNS. UNSTABLE AIR IS
LIKELY TO COMBINE WITH AN APPROACHING COLD FRONT TO GENERATE
SCATTERED THUNDERSTORMS, A FEW OF WHICH COULD BECOME SEVERE.

A SEVERE THUNDERSTORM WATCH HAS ALREADY BEEN ISSUED THROUGH 400 PM
FROM MIDDLESEX SOMERSET AND HUNTERDON COUNTIES AND NORTHWARD IN NEW
JERSEY, AS WELL AS LEHIGH NORTHAMPTON CARBON AND MONROE COUNTIES IN
EASTERN PENNSYLVANIA.

PEOPLE SHOULD STAY ALERT TO CHANGING WEATHER CONDITIONS AND MOVE
INDOORS SHOULD THUNDERSTORMS APPROACH. STAY TUNED TO NOAA WEATHER
RADIO, THE VOICE OF THE NATIONAL WEATHER SERVICE, OR LOCAL MEDIA FOR
THE LATEST WEATHER INFORMATION.

ALSO, TEMPERATURES OF 85 TO AROUND 90 DEGREES AND DEW POINTS OF
65 TO 70 WILL COMBINE TO RAISE THE HEAT INDEX TO 90 TO 95 THIS
AFTERNOON, ESPECIALLY IN THE URBANIZED AREAS OF THE DELAWARE VALLEY.
IF YOU ARE GOING TO BE OUTDOORS THIS AFTERNOON, AVOID OVERHEATING
YOURSELF. BE ESPECIALLY CAREFUL WITH THE ELDERLY, THE VERY YOUNG AND
THE INFIRM, AS THEY ARE MOST SUSCEPTIBLE TO HEAT STRESS. ALSO,
PLEASE REMEMBER TO KEEP YOUR PETS COOL. MAKE SURE THEY HAVE ACCESS
TO A SHADY AND WELL VENTILATED LOCATION AND COOL WATER TO DRINK. IF
AT ALL POSSIBLE, BRING THEM INDOORS.
