Well, I have to say that things do seem like they are getting interesting. While I still have a lot of doubts that this will be anything other than a rain event with a little snow at the end, here is the updated Thursday Night through Sunday NWS forecast for my area:
Thursday Night
Cloudy. Rain and snow likely after midnight. Lows near 30. Chance of precipitation 60 percent.
Friday
Rain and snow likely. Highs in the mid to upper 30s. Chance of precipitation 60 percent.
Friday Night
Breezy. Cloudy with a chance of rain and snow. Lows near 30. Chance of precipitation 50 percent.
Saturday
Breezy. Rain and snow likely. Highs in the mid to upper 30s. Chance of precipitation 60 percent.
Sunday
Mostly cloudy and breezy. A chance of rain and snow showers. Lows in the upper 20s. Highs in the upper 30s.
And then there is this NWS statement:
Statement as of 3:00 PM EST on December 2, 2003
...The First Significant Winter Weather Event Of The Season Is Possible Thursday Night And Into The Weekend Over Eastern Pennsylvania...New Jersey...Northeastern Maryland...And Delaware...
A slow-moving coastal storm... or what may be a couple of storms... is taking shape for late this week and into the weekend for the northern mid-Atlantic area. The first surge of moisture associated with this system is expected from the south Thursday night. Temperatures will be cold enough for rain to mix with snow over eastern Pennsylvania and central and northwestern New Jersey... with precipitation possibly weighted more toward snow or occurring as mostly snow north and west of Philadelphia.
As the next low moves northeast and possibly stalls near the area or off the mid-Atlantic coast Friday night into Saturday... and upper level energy moves overhead... more wintry precipitation is possible into the weekend. Wintry weather may extend southward into portions of northeastern Maryland and Delaware as cold air is drawn south.
In addition... a strong onshore flow is likely with this storm. If this materializes... there is a threat of coastal flooding due to the strong northeast or easterly flow and the approaching full moon.
A significant accumulation of snow is possible over parts of the region late this week and into the weekend... so the National Weather Service is providing advance notice of this possibility. However... since confidence is low in the computer models and in exactly how this situation will play out at this time... area residents and travelers to the region are urged to pay close attention to later forecasts and possible watches warnings or advisories as the event gets closer.
