.MARINE...
**SINCE MUCH OF DELAWARE BAY IS COVERED BY ICE WE BEGIN ADDING
PHRASING "ON ICE FREE WATERS" FOR THE FIRST FOUR PERIODS OF THE
FORECAST**
STRONG COLD FRONT WILL SHIFT EAST ACROSS THE WATERS LATE THIS
EVENING. BECAUSE THE FRONT HAS ALREADY ARRIVED AT KILG, HAVE MOVED
UP THE START TIME OF THE GALE WARNING TO BEGIN NOW ON THE DELAWARE
BAY. START TIMES OF THE GALE WARNINGS FOR THE ATLANTIC COASTAL
WATERS ARE UNCHANGED FROM THE PREVIOUS FORECAST. GALES CONTINUE

SUFFICIENT FOR FRIDAY AFTERNOON.
MAINTAINED A HEAVY FREEZING SPRAY WATCH FOR THURSDAY NIGHT INTO

LOW WATER ADVISORIES MAY BE NEEDED FOR THE LOW TIDE CYCLES
THURSDAY AND FRIDAY MORNINGS FOR THE COASTAL WATERS, AND POSSIBLY
THE DELAWARE BAY AND THE TIDAL DELAWARE RIVER.
&&
.CLIMATE...
RECORD LOW TEMPERATURES ARE ANTICIPATED THIS THURSDAY AND OR FRIDAY
MORNING WHEN WE NOW THINK THE COLDEST DAYS OF THE WINTER SHOULD
OCCUR. THIS BECAUSE MINUS 25C 850 MB AIR IS MORE MODELED TO
OVERSPREAD MORE OF OUR AREA AND SIT HERE FOR 12 HOURS. EVEN
SATURDAY MAY HAVE RECORD COLD NEAR MIDNIGHT BEFORE TEMPS START
RISING AHEAD OF THE NEXT ARCTIC COLD FRONT.
WE'RE TALKING THE COLDEST AT PHILADELPHIA SINCE JAN 19, 1994 WHEN
IT WAS 5 BELOW. IT WILL PROBABLY BE EASIER TO GET BELOW ZERO LATE
THIS WEEK DUE TO THE SOUTHWARD SNOW COVER INCREASE.
ADDITIONALLY FOR THE URBAN CENTERS AND THAT WILL FOCUS ON PHL...IF
THE LOW IS ZERO OR COLDER THIS WILL BE COLDEST LOW TEMPERATURE
AT PHL - SO LATE IN THE SEASON!
