Just in time for our Mother’s Day weekend, “Mother Nature” herself is giving the gift of clouds, showers, and maybe even a little snowfall. Oh, also a nor’easter!
The same energy associated with the tornadic weather Friday on the Gulf Coast will move up the eastern seaboard Saturday and Sunday (Mother’s Day) bringing heavy rain at times.
The severe weather aspect from this system will provide a chance of severe thunderstorms across the Southeast, while colder and more stable air helps eliminate the severe threat for the Northeast. The timing looks like this: The coastal low will develop just off the Chesapeake Bay on Saturday afternoon while it gets slightly stronger. The central pressure of the storm will continue to drop Saturday night, showing signs of strengthening while it moves closer to Long Island and Cape Cod by Sunday morning.
Then, like a classic New England coastal storm, the forecast is for the low pressure center to fall to around 987 millibars Sunday night off the coast of Maine. The forecast calls for a 24-hour central pressure fall of 17 millibars, which does not classify it as a “bomb” however still shows that it will be a quickly-strengthening low. By Monday the low nearly stalls off the coast of Maine, which will keep the Northeast in a cool and breezy weather pattern.
Here are the forecast numbers from the mid-Atlantic to the Northeast from Saturday to Sunday
Rainfall: 1 – 2″ possibly up to 3″ in isolated spots
Snowfall: Maybe a few inches above 4,000 feet elevation, any snow mostly confined to the New Hampshire’s White Mountains
Winds: Sustained 10-20 mph, but coastal gusts could reach 50 mph briefly
Temperatures: Merely 40’s and 50’s for high temperatures!
Suggestions: Indoor ideas with mom? Maybe a good idea. Carry along the umbrella and hold onto it tight! Have a backup plan in case you’re set on your outdoor plans this weekend.
