2nd Noreaster In 5 Days Will Impact Delaware to Southern New England South Central PA, North Central MD On The Edge

Friday's fierce Noreaster which impacted many states with wind and rain from the Middle Atlantic States to New England is sitting well offshore but it is part of the equation that will create a second storm on Wednesday. This storm will intensify to a rather formidable system however the impacts will be be a bit different from the last one. First off I don't think that winds will be as widespread as the last system  Also we have a colder up air environment this time around. South Central Pennsylvania and North Central Maryland will be on the edge of this with the chance for some snow developing Wednesday into the afternoon but the main development will be further north and east. Right now I think this will limit snowfall for our area.

 

Noreasters have been few and far between for the last several years and as always happens in the world of weather it is either feast or famine. The strong Greenland Eastern Canada block has gained a foothold and it looks hold in position all this week. Friday's noreaster came with the block just building in so cold air was limited. This time however we have the interaction of Friday's storm which is still out to our southeast and stalled and the block to the north. The rotation of the old storm is actually creating a bit of a backdoor front that will be moving through tonight. A few snow showers are possible with this over Eastern Long Island and Eastern Connecticut. The end result will be a colder upper air profile over the Northeast and the Northern Middle Atlantic States.

 

 

 

By Wednesday morning the secondary low is revving up along the North Carolina coast and notice that the freezing line is still well to the south in the Southern Delmarva Peninsula so this is a much colder upper atmosphere profile than what we had on Friday. Everything in the upper air suggests a coastal track for this storm which will pinch the cold air long the coast as well as inland areas. The usual model errors apply at this stage. I think the one direction this could shift is further to the east rather than west because of the strong block to the north.
