 Well many areas across Pennsylvania New York State and New England are seeing snow, While a large part of southern/central New Jersey up along the coastal plain in New England is seeing plain rain, as the latest storm is moving through the region.

Here's a look at the surface chart and radar

The storm seems to have read my forecast over the last couple of days. Because it seems to be following it as a script; as it appears to be doing very much like what I anticipated it would be. The storm should be exiting Maine by daybreak tomorrow. From what I'm seeing snowfall accumulations are falling into line with the forecast. Please share your observations and snow measurements. Yesterday's post didn't get near the views I thought it would. I'm not sure why this is the case. But I guess it is what it is.

A few days ago I talked about this nor'easter probably bombing out as it approached Nova Scotia. Some of y'all have asked, what does bombing out mean? The technical meteorological term is called bombogenesis,  But sometimes it is called a bomb cyclone. Bombogenesis is when a storm like a nor'easter quickly Intensifies. To become a bomb cyclone the central pressure of the mid latitude cyclone generally must drop at least 24 millibars in one day. The process is similar to when a hurricane undergoes rapid intensification. If you want to know more about bombogenesis let me know and I will make a post on it. The storm  is going to continue to deepen and end up bombing out as it gets up over Atlantic Canada. But this will be too late to bring us more in a way of a significant nor'easter for our region.

The current infrared satellite image. Shows how quickly the system is moving. As the bulk of it has passed to the east of western New York State and Pennsylvania.

Area south and east of Lakes Erie and Ontario W ill see some lake effect snow develop this evening into tonight. Any lake effect should be winding down tomorrow morning.

High pressure is going to build in tomorrow, providing coolest temperatures and a mix of sun and clouds. But all in all it should be a fairly tranquil day! Wednesday night into Thursday a strong arctic front is going to be dropping through the region. Behind this cold front we are going to see arctic air invade the region. Starting Wednesday night and through Thursday; we are going to see several rounds of snow showers and squalls work through the region. These squalls will make driving difficult And could drop quite a few inches in some spots over a short period of time, as they roll through. Behind the front temperatures are going to go into free fall, as the coldest air so far drops into the region. Northern parts of New York State and northern New England temperatures are going to drop well below 0° F. The rest of the region will see temperatures in the single digits into the low 20s, and low 30s on the Coast. Thursday is going to be quite windy. Downwind of Lake Erie and Lake Ontario, lake effect snow bands are likely to set up during the afternoon into the evening. These should be short lived and  should be diminishing by Thursday night. The heaviest bands could drop a few inches of snow during this time

Friday we are going to see high pressure approach and quickly move through.  Behind this we're going to see possibly two storms moving eastward across the country. These storms look to be quite similar to the one we're dealing with right now. We're going to have a disturbance in the northern polar jet and a disturbance in the southern subtropical jet.  

Depending on the speed and strength Of the jet stream that's going to be dipping and moving through. will determine how these are going to interact Right now For friday night into Saturday it appears like the two features will not phase, And the southern part of the disturbance Looks to head north and east south of our region. This likely brings rain along and south of the I-95 corridor with some snow north and west of there across northeast Pennsylvania into southeast New York State and across the southern half of New England, as the storm slips out to sea. The northern component could bring a few snow showers across New York State into northern New England, But it shouldn't be very impactful. The air in place is going to be very cold. So we'll just have to see how this looks to evolve as we move over the next couple of days. We look to see another storm slip through for later Saturday and Sunday. The overall setup looks to be similar to the one going through for the first part of the weekend. It wouldn't take much for a partial or even full phase on either one of these systems. If this occurs They would become much bigger storms with large impacts across our region.
