Welcome to the first day of Astronomical Spring.

The surface chart shows primary low pressure moving into the Great Lakes with an attached cold front.

 

Satellite shows the system approaching our region, and another moving into the Pacific Northwest.

 

We have rain showers ahead of the cold front over western parts of the region. This rain will continue to push east over the course of today and tonight. Rain could be moderate to heavy at times.  General rain amounts look to be 0.25 to 0.50 of an inch. Out ahead of the frontal boundary it is still mild. A secondary low is going to form along the frontal boundary. Southern winds will ramp up to 10-20mph, with gusts 30-50 mph. There will be a chance for isolated thunderstorms; especially over much of Pennsylvania, New Jersey, Maryland, and Delaware, a few of these could be on the strong side. Cold air will come in behind the front, this will turn rain over to a mix/snow The Poconos could see a few snow flurries that lead to some accumulation.  While most areas across northern Pennsylvania, Northwest New Jersey, New York State, and New England, look to see some snow showers, little to no accumulation is likely. The risk for accumulating snow of a couple of inches is greater for elevations of 500 feet and above, with the higher elevations above 1500 feet in the Catskills, Berkshires,  Adirondacks, Greens and Whites, 3 to 6 inches will locally higher amounts will be possible in these areas

Tomorrow will remain chilly with gusty winds hanging around Saturday will see the winds lessen with temperatures becoming warmer. Saturday starts out dry, but a weak disturbance slides through during the day producing a chance for isolated rain showers and high elevation snow showers. Sunday is looking to be generally dry, but another cold front will approach and move through later in the day into Monday, bringing more in the way of widespread rain, general amounts are looking to be 0.25 to 0.50 of an inch, as colder air filters in with the trough, rain showers will likely change over the snow showers especially in the high elevations.

 

The next couple of weeks will feature general coolness, as we experience a lot of trougheness over the Great Lakes and the Northeast. As I said in my long-range post yesterday the pattern will remain active. So as these systems roll out of the west, we will have to be watchful for snow on the northern side of the tracks. There is still the chance for a surprise snowstorm for at least part of the region.
