SOME LIGHT SNOW MOVED ACROSS PARTS OF NORTHERN AND EASTERN NEW JERSEY
OVER THE PAST 24 HOURS WITH JUST A FEW FLURRIES ELSEWHERE. ACROSS
PARTS OF NEW JERSEY WATER EQUIVALENTS WERE UNDER A TENTH /0.10/ OF AN
INCH.
A VERY COLD DAY IS ON TAP FOR OUR ENTIRE HSA. THE EXTREMELY COLD
WEATHER WILL CONTINUE TO CONTRIBUTE TO ADDITIONAL ICE CREATION ON
RIVERS AND STREAMS. ICE EFFECTS COULD LEAD TO ABRUPT FLUCTUATIONS OF
SEVERAL FEET ON RIVERS AND STREAMS.
THE NEXT STORM SYSTEM IN THIS COLD NORTHWEST FLOW APPEARS TO BE A SLOW
MOVER AND BRING A PROLONGED PERIOD OF LIGHT SNOW ACROSS PARTS OF
NEW YORK, PENNSYLVANIA AND NEW JERSEY FROM SATURDAY NIGHT THROUGH
SUNDAY.
NEARLY STEADY OR SLOWLY FALLING RIVER LEVELS ARE EXPECTED FOR THE NEXT
SEVERAL DAYS. ICE EFFECTS WILL CONTINUE OVER THE NEXT SEVERAL DAYS.
