Following a cold start on Monday, this week’s weather is forecast to be tranquil and increasingly mild. High pressure is expected to set up in the Atlantic and will provide a southwesterly flow of mild air and fair skies.

A weak disturbance will move through Tuesday and another Thursday night with just some cloudiness. Otherwise fair skies.

Temperatures are forecast to reach the mid to upper 60s by the end of the week. Even next weekend is currently expected to be mild and dry.

The next system that might affect us might be the remnants of the latest tropical–“Eta”. The same high pressure system that will provide our nice weather will also block the northern movement of Eta in the short run. However, that won’t be until next week.


As first noted last night, Sunday’s forecast for late afternoon light showers has changed significantly.

A strong cold front will spawn coastal low pressure.  Rain will move in around  noon.  Winds will become gusty by late morning with gusts 35-40 mph. Accumulated rain will be about 0.4-0.6”, higher in NJ.   High temperature 53-55°

The actual cold front moves through between 5-6 PM with a shift in winds to the NW.  Still gusty winds.

Temps drop into the 30s during the Eagles game.  Winds gusty early will reduce somewhat by late evening.


Wed 03:56 PM Update — Today’s latest models continue with earlier exit of the rain and the passage of the weak cold front.

Some models have the rain ending as early as noon Thursday. The model blend has the rain ending between 12-2PM. Sunshine breaks out shortly after the rain ends.

A strong cold front moved through on Friday, following the departure of the remnants of what was Hurricane Zeta. Winds have shifted to the NNW and colder air will filter in for Friday night into Saturday.

Cold temperatures at daybreak Saturday. Most areas are forecast to be at or below freezing.

High pressure will be in control on Saturday but will quickly depart Saturday night and a return flow of milder air (and moisture) will move in for Sunday before another cold front moves through Sunday afternoon.
