We are now on a wild roller coaster ride when it comes to the weather in the North East. A low pressure system is moving out of the Great Lakes and will be transferring its energy to a secondary low off the NJ coast.
Graphic overview of storms.
As you can see, there are many factors playing into the forecast. The coastal front, the new low, cold air damming. Cold air damming is when the heavy cold air stops the advance of Warm air. Where exactly the cold air dam sets up will play a big part in the type of precipitation. The coastal front will play an equally important part on determining precipitation types. As shown, the east winds off the warm water will bring in warmer air. This will turn snow/sleet/freezing rain into all rain. Expect this to move inland Monday-tuesday.
After the coastal front moves inland, Wednesday will already be here as will another storm. This new storm will be MUCH stronger.
This graphic depicts the setup Monday-Wednesday. The coastal front from tonight will move way inland turning everyone except the ski resorts over to plain rain. The wednesday low will move swiftly through the Gulf of Maine and into the Canadian Maritimes. On the backside of this system the cold air will make a comeback turning everyone back over to snow Wednesday evening-night. Accumulations should be light.
After we get the Monday and Wednesday storms out of the way, there will be yet another low Friday. This is a little too far out to accurately forecast so I will detail that in a later Post coming Wednesday-Thursday.
