Philly Winter Weather Outlook

Another week of well-above average temperatures is expected for our area, and this has been highly advertised by most of the news and weather shows.  Indeed, relatively mild weather is likely through the end of 2015.

Of interest is a change in weather pattern configuration that seems to be suggested by the some of the long-range models.   For the first time this season, a mixed precipitation storm (mostly rain for us) may occur sometime around December 29th.

Even more interesting, the GFS is suggesting a major nor’easter sometime around January  5th.

I wouldn’t take any of these specific GFS forecasts too seriously at this time, but what’s noteworthy is that the GFS is for the first time this season predicting some serious interaction between between cold air and the El Ninio moisture right in our area .

 

Update 12/21 –  Some of those long range pattern changes suggested by the GFS have disappeared.   It looks warm into the first week of January.
