THE NATIONAL WEATHER SERVICE HAS ISSUED A FLOOD WATCH FOR TONIGHT
INTO THURSDAY MORNING FOR THE FOLLOWING AREAS.
 
A LOW PRESSURE SYSTEM OVER THE MIDDLE MISSISSIPPI VALLEY WILL
INTENSIFY AS IT MOVES NORTHEAST THROUGH THE OHIO VALLEY, MOVING
THROUGH THE SAINT LAWRENCE VALLEY LATER THURSDAY. A STRONG COLD FRONT
WILL PASS THROUGH OUR AREA EARLY THURSDAY MORNING. ON ITS WAY, THE
SYSTEM IS EXPECTED TO PICK UP MOISTURE FROM THE GULF 
OF MEXICO AND THE ATLANTIC OCEAN. 

RAIN IS EXPECTED TO REACH OUR REGION LATE IN THE DAY TODAY OR THIS
EVENING AND INTENSIFY OVERNIGHT. RAINFALL AMOUNTS OF ONE 
TO ONE AND ONE HALF INCHES ARE LIKELY. THE BULK WILL FALL QUICKLY
WITHIN ABOUT A SIX HOUR PERIOD. ADDITIONALLY, UP TO ONE 
EXTRA INCH OF LIQUID IS POSSIBLE DUE TO THE MELTING SNOW.  

THE COMBINATION OF HEAVY RAIN AND SNOW MELT COULD CAUSE FLOODING 
ALONG SMALL STREAMS AND CREEKS AND IN AREAS OF POOR DRAINAGE LATE 
TONIGHT AND THURSDAY MORNING. STORM DRAINS MAY BE CLOGGED WITH SNOW 
OR LEAVES THAT WERE NOT COLLECTED BEFORE THE WEEKEND SNOW STORM. 
THIS COULD COMPOUND ANY FLOODING. MAIN STEM RIVER FLOODING IS NOT 
ANTICIPATED AT THIS TIME, BUT WILL BE MONITORED. AN ADDED
COMPLICATION MIGHT BE THE THURSDAY MORNING COMMUTE WITH OR WITHOUT
THE FLOODING. HEAVY RAIN MIGHT LINGER INTO THE START OF THE MORNING
COMMUTE...ESPECIALLY IN THE PHILADELPHIA NORTHERN SUBURBS AND CENTRAL
NEW JERSEY.

IN ADDITION TO THE FLOODING POTENTIAL...THE WARMER AIR PASSING OVER
THE SNOW COVER IS EXPECTED TO GENERATE AND ENHANCE THE FOG TONIGHT
AND EARLY THURSDAY MORNING. THERE COULD BE PATCHES OF VERY DENSE FOG
TONIGHT.
 
GIVE YOURSELF EXTRA TIME TO REACH YOUR DESTINATION THURSDAY MORNING.
 
A FLOOD WATCH MEANS THAT FLOODING OF STREAMS...CREEKS AND OTHER
DRAINAGE AREAS IS POSSIBLE WITHIN THE WATCH AREA. PEOPLE IN THE WATCH
AREA SHOULD KEEP AN EYE ON THE WEATHER AND BE PREPARED FOR IMMEDIATE
ACTION SHOULD HEAVY RAINS AND FLOODING OCCUR OR A FLOOD WARNING BE
ISSUED.
