Scattered severe thunderstorms with a threat of wind damage and possibly a couple tornadoes are expected to develop Friday from the Carolinas northward into the Mid-Atlantic.
The Storm Prediction Center has issued the following watches:
- Severe Thunderstorm Watch until 7 p.m. Eastern for Delaware, eastern Maryland, southern and western New Jersey, southeastern Pennsylvania and coastal waters.
This comes as a cold front slowly advances east toward the East Coast. The slow-moving storm system should then gradually begin to edge offshore of the Mid-Atlantic and Northeast by Sunday as a weak area of high pressure builds in across the Ohio and Tennessee Valleys, the National Weather Service said.
The front will interact with a very moist and unstable airmass advancing up across the coastal plain and should result in numerous areas of heavy showers and thunderstorms across the Mid-Atlantic and Southeast.
There will be a concern for some severe weather from the Carolinas northward into the Mid-Atlantic that may result in damaging winds and a couple of tornadoes. Some storms may also produce heavy rainfall rates of 1 to 2 inches per hour resulting in localized flash flooding.
High temperatures will be in the 70s to near 80 degrees in the Northeast, while the Southeast should manage the lower to mid-80s.
The heavy rain and storms will linger across the Northeast on Saturday. While most of the activity will be off the coast, a few intense storms will move through New England potentially containing 60-plus mph winds and hail.
Much nicer conditions are expected Sunday and Memorial Day.
