Area forecast discussion, Apr 24, 3:34 AM EST, 4 hours 4 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 434 AM EDT MON APR 24 2006 .SHORT TERM /TODAY THROUGH WEDNESDAY/... THE UPPER LOW OVER THE NORTHEAST IS KEEPING US FAIRLY BUSY WITH PLENTY OF OVERNIGHT SHOWERS AND THUNDERSTORMS ACROSS MUCH OF THE REGION. SOME SVR STORMS MOVED ACROSS THE DELMARVA AND SRN NJ WITH LARGE HAIL BEING THE MAIN FACTOR. EVEN AT THE TIME OF THE AFD STORMS STILL CLOSE TO SVR WITH HAIL JUST TO THE NW OF THE REGION. THE MAIN S/W THAT IS CONTRIBUTING TO THE CONVECTIVE WEATHER WILL SWING ACROSS OUR AREA THIS MORNING. ONCE THAT HAPPENS, A WESTERLY FLOW WILL INCREASE ACROSS THE AREA TODAY AND IT SHOULD BECOME DRIER. I HAVE LEFT AREAS OF FOG IN THE MORNING FCST AS THERE IS A WIDE RANGE OF VSBYS ACROSS THE AREA. SHOWERS AND ISOLATED THUNDERSTORMS WILL BE SCATTERED ACROSS MOST AREAS THIS MORNING, BUT MORE CONCENTRATED CLOSER TO THE UPPER LOW TO THE NORTH, WHERE POPS WILL BE IN THE LOW LIKELY CATEGORY. A FEW SHOWERS MAY LINGER UP NORTH INTO THE EARLY AFTERNOON. CONDITIONS WILL BE MAINLY CLEAR AND COOL TONIGHT. I ADDED SOME PATCHY FOG IN THE FCST AS THERE WILL STILL BE PLENTY OF MOISTURE AROUND FROM THE PREVIOUS RAINS. IN COLLABORATION WITH SURROUNDING OFFICES, I SPED UP THE TIMING OF THE PRECIP FOR TUESDAY. THE GFS IS SHOWING A COLD FRONT MOVING ACROSS THE AREA DURING THE AFTERNOON WITH A LOW FORMING ALONG IT AND MOVING JUST TO OUR SOUTH. MUCH OF THE PRECIP WILL PROBABLY BE IN THE AFTERNOON AND EARLY EVENING. I DIDNT MAKE TOO MANY CHANGES BEYOND TUESDAY THOUGH. ONCE THE COLD FRONT PASSES TUE NIGHT A HIGH WILL BUILD IN AND PROVIDE PLEASANT AND COOL WEATHER FOR WEDNESDAY. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... THE EXTENDED DISCUSSION FROM THE AFD FROM SUNDAY IS BELOW. HIGH PRESSURE IS FORECAST TO BUILD DOWN INTO OUR REGION FOR THE SECOND HALF OF THE WEEK WITH DRY WEATHER AND NEAR SEASONABLE TEMPS. A MID LEVEL LOW IS EXPECTED TO DROP DOWN INTO THE GREAT LAKES AND THE OHIO RIVER VALLEY DURING NEXT WEEKEND, BRINGING OUR REGION AN INCREASE IN CLOUD COVER ALONG WITH AN INCREASING CHANCE FOR PRECIP. && .AVIATION... QUITE THE VARIETY OF WEATHER ACROSS THE REGION TONIGHT. DENSE FOG HAS MOVED IN ON AN EASTERLY FLOW OFF THE OCEAN HAS INVADED THE NORTHERN AREAS AND INTO KTTN AND KABE. THUNDERSTORMS DIDNT GIVE UP OVERNIGHT AND CONTINUED TO FIRE ACROSS MD/DE AND SRN NJ AND HAVE AFFECTED KILG AND KMIV AND GETTING CLOSE TO KACY. LOOKS LIKE -SHRA/-TSRA AND AREAS OF FOG (LOCALLY DENSE) WILL CONTINUE UNTIL S/W MOVING ACROSS PA MOVES BY THIS MORNING. WX CONDITIONS SHOULD IMPROVE LATE THIS MORNING FROM WEST TO EAST AS WESTERLY WINDS MOVE IN AND LOW LEVEL DRYING OCCURS. && .MARINE... SMALL CRAFT CRITERIA SEAS CONTINUE ACROSS THE NJ/DE COASTS THIS MORNING AND I WILL CONTINUE THE SCA FLAG INTO THE EARLY AFTERNOON. THE SEAS SHOULD GRADUALLY DIMINISH TODAY AS THE WINDS WILL NOT BE TOO STRONG. THE SE TO S WINDS OVER THE WATERS EARLY TODAY WILL SHIFT AROUND TO W BY THE AFTERNOON AND SPEEDS WILL INCREASE TO BETWEEN 10 AND 15 KTS. SCA CRITERIA WINDS ARE AGAIN POSSIBLE TUE INTO WED AS THE NEXT SYSTEM APPROACHES. GUIDANCE FOR TUE NIGHT AND WED MAY BE A BIT LOW WITH SEAS ONLY GOING TO 4 FT AT 44009 AND 5 FT (FOR A FEW HOURS) AT 44025. MY FCST TACKED ABOUT 1 FT TO THESE VALUES. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
