The snow is here.


 



The surface chart shows, low pressure in the Great Lakes, with low pressure developing off the Coast.  The radar out of P-State shows rain showers, and higher elevational snow showers. The coastal/nor’easter is going to continue to develop, first it will drift north and west into New York State, then it slows down and looks to maybe stall tonight, before dropping back south into Pennsylvania tomorrow.

This will be a fairly long event, lasting into Saturday.

Today and tomorrow will be gusty with 10-20 mph, with gust of around 30 mph inland, those near and along the coast will see high winds with gust of 30 to 40 mph.  Over the next few days we’re going to be dealing with some shortwave troughs that will move through, helping to produce and enhance rain and snow showers.

The rain over the next few days will 0.50 to 1.50 inches with higher amounts possible, this rain will be widespread and the first meaningful rain large parts of the region has seen in months.

The  Appalachians look to get a good thump. As I said yesterday, accumulating snowfall will be elevational, Elevations above 1000 feet could see an inch or two, with the bulk of the snow for those above 1500 feet. The lower elevations and valleys could end up mixing as colder air moves in later today and tomorrow. Even those in New York City and even Philadelphia could see a few snowflakes. But these areas won’t see any real measurable snowfall.  The higher elevations will see 2 to as much as 8 inches of wet snow, with the highest peaks of the, Poconos, Catskills, Adirondacks, Greens, and whites seeing 8 to 12 inches with localized amounts of around 14 inches possible.

I still think the general overall map I made yesterday is still valid. 



late Saturday and Sunday the system will start to drift away, leaving lingering scattered rain/snow showers around for Sunday. The weekend will see limited lake effect off of the Great Lakes as well.

High pressure builds back in for Monday, with temperatures staying chilly, but generally dry conditions. A weak cold front will slide through for Tuesday bringing scattered to isolated showers. Can't rule out lake enhanced rain/snow showers

For Wednesday into Thanksgiving, high pressure will be overhead.

There is a chance another cross-country storm impacting part of our region end of next week. The pattern looks to stay active for the next couple of weeks. Then I still think a substantial cold snap will be coming in for Mid-December.
