Midweek Rain & Storms Across the East Coast

14 Dec 2020, 2:20 pm

After an early week coastal storm exits the Mid-Atlantic, our next big storm is expected to move in mid-week. This will not only bring the potential for heavy snow up north, this will also bring the risk for rain and some severe thunderstorms possible. The chance for strong thunderstorms will be in the northern Florida Peninsula and also through the Inner and Outer Banks of North Carolina.

Forecast

A low pressure system currently over the Southern Rockies is expected to move southeastwards towards the Gulf Coast late Tuesday evening. Alongside this low pressure system, another area of low pressure will develop along the southeast coast and move northwards along the Atlantic towards the Mid-Atlantic on Wednesday. With two low pressure systems, there will be two areas that bring a risk for marginally severe storms. For more on the severe weather outlook, scroll down.

The ‘northern’ low in the Mid-Atlantic will bring snow to the north and rain to the south. Similar to the set-up we saw with Monday’s coastal storm with the south side posing a storm threat and the north-side bringing snow.

Severe Outlook

The Storm Prediction Center has issued a marginal risk for severe storms (level 1 on a scale 1 to 5) for Florida and eastern North Carolina.

Around the low pressure system in Eastern North Carolina, there is a chance for some destabilization in the Inner and Outer Banks by Wednesday afternoon. If storms destabilize, there will be enough shear in the atmosphere for supercells. This means an isolated tornado and damaging wind gusts will be possible.

Along the Florida Peninsula, we will likely see storms organize and bring a similar threat around the low as those in North Carolina.

Forecast Accumulation

On the warm side of these low pressure systems we may see up to 1-2″ of rain. Here’s a look at our rainfall forecast:

Coastal Alerts

Coastal Flood Watches have been issued for Thursday for one to two feet of water inundation along the Maryland and New Jersey Coastline. This includes Middlesex through southeastern Burlington County in New Jersey. Widespread roadway flooding is likely along the coastal roads.
