Following a seasonably cold weekend, next week will be very warm and wet.  The anomalously warm temperatures will return.  X-mas eve looks to be warm and wet.

The very mild weather that will be with us through Friday will come to  brief end later Friday as a cold front moves through.

As in recent months, the cold front precipitation dynamics move to our north as a wave develops on the front to our south.  That gives us a windy day, but low rain probability to the frontal passage late Friday.

The current dry pattern seems deeply entrenched for our area.  Indeed, the upper air pattern that has been with us since August is a marked departure from the pattern of the past two years.  It suggests a much milder winter and possibly a much drier winter.  More about that in a upcoming post regarding my Winter Weather Outlook.

Back to this weekend…the wave of low pressure may bring cloudiness to our area on Saturday, but it appears that the rain will stoy just to our south, affecting southern NJ and DE.

For Sunday, cooler high pressure builds in for sunny and seasonably cool weather.

I’ll update on Friday.

The first significant dip in the jet stream for this fall/winter season will occur this weekend for the northeastern US.  A cyclonic flow of cool/colder air will bring temperatures down to about 40 or less at night and the 50s during the day.

While the predicted upper air  jet pattern has been consistent, the models have shown great variation with the possibility of upper air disturbances embedded in the flow.  What this means is that it’s not a certainty how much sunshine we’ll get with these cooler temperatures.

Periods of sun and cloudiness looks to be the best bet, and there’s a slight chance of a quick sprinkle during the afternoon on Saturday and even moreso later Sunday afternoon and evening, as the upper flow changes to the southwest.  A brief snow flurry Sunday night isn’t out of the question.

I’ll update Friday evening.
