SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
430 AM EST SUN FEB 9 2003

...ANOTHER ROUND OF SNOW EXPECTED ON MONDAY...

A LOW PRESSURE SYSTEM DEVELOPING IN THE TEXAS OKLAHOMA PANHANDLE 
TODAY WILL MOVE RAPIDLY EAST REACHING THE NORTH CAROLINA COAST ON 
MONDAY. THIS LOW WILL THEN INTENSIFY AS IT MOVES NORTHEAST MONDAY 
AFTERNOON AND NIGHT. AT THE SAME TIME AN ARCTIC COLD FRONT WILL BE 
APPROACHING THE REGION AND SHOULD PASS ACROSS US MONDAY NIGHT.

ONCE AGAIN SNOW IS EXPECTED TO OVERSPREAD THE REGION. INITIAL TIMING 
IS FOR IT TO ARRIVE BEFORE DAYBREAK ACROSS THE DELMARVA PENINSULA 
AND EXTREME SOUTHERN NEW JERSEY...DURING THE MORNING COMMUTE IN THE 
PHILADELPHIA METROPOLITAN AREA AND THE REST OF SOUTHERN NEW JERSEY 
AND BY NOON ACROSS NORTHERN NEW JERSEY AND THE REST OF EASTERN 
PENNSYLVANIA. 

ACROSS THE LOWER DELMARVA PENINSULA AND SOUTHEAST NEW JERSEY ENOUGH 
WARM AIR IS EXPECTED TO MOVE NORTH TO MIX THE SNOW OR CHANGE IT 
COMPLETELY TO RAIN. ACROSS THE REST OF DELMARVA...THE PHILADELPHIA 
METROPOLITAN AREA AND CENTRAL NEW JERSEY TEMPERATURES ARE EXPECTED 
TO BE AROUND FREEZING AS THE SNOW FALLS. THIS SHOULD CAUSE SLUSHY 
ACCUMULATIONS ON ROADS WITH MORE EFFICIENT ACCUMULATIONS ON ALREADY 
SNOW COVERED SURFACES. IN NORTHWEST NEW JERSEY AND FROM THE LEHIGH 
VALLEY NORTHWARD...TEMPERATURES SHOULD BE AT OR BELOW FREEZING 
THROUGHOUT THIS EVENT AND THE SNOW WILL ACCUMULATE EASIER ON 
UNTREATED ROADWAYS AND BRIDGES.

PRECIPITATION SHOULD TAPER OFF FROM SOUTHWEST TO NORTHEAST DURING 
MONDAY AFTERNOON AND MAY BE OVER IN TIME FOR THE EVENING COMMUTE 
FROM PHILADELPHIA AND CENTRAL NEW JERSEY SOUTH.

THIS LOW PRESSURE WILL NOT HAVE THE AMPLE MOISTURE ITS PREDECESSOR 
HAD ON FRIDAY. BUT IT WILL HAVE A VERY STRONG JET STREAM TO HELP 
ENHANCE THE PRECIPITATION. 

INITIAL ESTIMATES ARE FOUR TWO TO FOUR INCHES OF SNOW TO ACCUMULATE. 
LESSER AMOUNTS ARE EXPECTED ACROSS THE LOWER DELMARVA AND EXTREME 
SOUTHEAST NEW JERSEY WHERE RAIN SHOULD MIX IN. THREE TO FIVE INCHES  
ARE EXPECTED ACROSS NORTHERN NEW JERSEY AS THE LOW BEGINS TO 
INTENSIFY AND INGEST MORE ATLANTIC MOISTURE.

PLEASE BEAR IN MIND THE TIMING AND ACCUMULATIONS OF THIS EVENT ARE 
INITIAL ESTIMATES AND WILL BE ADJUSTED AS WE GET CLOSER TO IT.

COMMUTING ON MONDAY SHOULD BE MORE DIFFICULT THAN USUAL. PLEASE BE 
PREPARED TO TAKE EXTRA TIME TO REACH YOUR DESTINATION.

NO MATTER HOW MUCH SNOW FALLS...ONCE THE ARCTIC FRONT MOVES THROUGH 
MONDAY NIGHT...A STIFF WEST WIND AND PLUNGING TEMPERATURES WILL 
OCCUR. THERE COULD BE SOME BLOWING AND DRIFTING OF THE SNOW AND 
ANY STANDING UNTREATED SLUSH OR WATER WILL FREEZE SOLID.
MONDAY NIGHT REFREEZING OF WATER ON ROADWAYS...ESPECIALLY BRIDGES 
AND OVERPASSES...WILL CREATE PATCHES OF BLACK ICE.  

UNSEASONABLY COLD AIR WILL PREVAIL FOR THE REST OF THE WEEK. AN 
ALBERTA TYPE LOW PRESSURE SYSTEM MIGHT EVEN BRING ANOTHER SMATTERING 
OF SNOW TUESDAY NIGHT.

DETAILS OR UPDATES.
