 System departs leaving nice weather in its wake!

November has been rather coolish across the region. The 1st week to 10 days saw generally seasonal temperatures, Some days were a bit warmer other days were a bit cooler. But overall temperatures across the region averaging out to near average during that time. The rest of the month Has generally been cooler; With temperatures across Pennsylvania, New York State and New England running around 1-3 °F below average. But there have been pockets across northern Maine as well as parts of Southeast Pennsylvania, Maryland, Delaware into southern New Jersey that have been running slightly above average overall. Where is the coolness Several areas across the region Have seen winter start "early" With many parts of New York State into New England having seen snow accumulation earlier than the last few winters.

Getting into today and the rest of this week. Let's take a look at the surface chart ,regional radar and latest satellite image

The surface chart shows low pressure to our south is exiting to the east as high pressure approaches and is building into the region. The system that's departing for the most part The precipitation over Pennsylvania and Maryland Delaware and New Jersey But a little bit of it did sneak into Southern Connecticut. There was a light accumulation of snow in the Poconos and up into northeastern Pennsylvania and northwest New Jersey. Accumulations were generally a dusting to an inch as expected. I have heard  southwest Connecticut also saw some snowflakes but I can't verify that. The region has a mixture of sun and clouds with temperatures a bit warmer than they were yesterday. Lighter winds generally 2 to 8 miles an hour with a few higher gust; are making the feel like temperature much nicer than last couple of days. Generally temperatures are still running slightly below average today the lack of wind makes it feel great! The lighter winds are going to lead to another cold night across much of the region. The high pressure is going to be sitting overhead tomorrow providing another tranquil day.

On the IR satellite We can see that little disturbance moving across the northern plains heading into the Midwest. This is going to be our weather maker for Friday as the high pressure slips to the east and  a weak cold front approaches the region. Ahead of the cold front we will see a light southerly wind, which will allow temperatures to warm up a little bit. The actual cold front will slide through later Friday into Saturday. For the vast majority of the region this will bring scattered spotty rain showers. But across northern into northwestern Maine a light accumulation of a dusting to a couple of inches will be possible. The cold front is going to quickly depart allowing high pressure to build in for Saturday night and Sunday. The high pressure looks remain overhead for Monday into Tuesday morning. During that time Conditions across the region should be quite nice and dry.  For Wednesday an area low pressure will approach along with a disturbance in the southern subtropical stream.  Yesterday I had thought precipitation would remain south of New York State and New England. But now these two interact just enough that along with the Middle Atlantic, rain showers and higher elevation snow showers across New York State and New England are possible, I can't rule out a little accumulating lower elevation snow across parts of northern New York State and northern New England, Unless the timing changes this looks to be out of here for Thanksgiving day.

As I've been saying for the last several days once we get past Thanksgiving, the arctic gates look to open up ushering in much colder air into the eastern half of the United States; as the western ridge builds and true arctic air drops into the Plains and then East Coast. But if you been following me, It won't be a surprise that you'll have to break out the winter coats.
