The Memorial Day weekend will begin cool, windy and rainy in New England. The storm system responsible for severe weather and deadly tornadoes over the Plains earlier this week will give birth to a new storm over the Northeast as the week draws to a close and the holiday weekend begins.

The event will start as locally severe thunderstorms Wednesday evening into Thursday evening spreading slowly from the Appalachians to the East Coast. As the storm strengthens, it will cause winds to kick up and will make a pocket of cool air in the region.

Friday night into Saturday could be a flat-out nasty way to start the summer season with a driving wind, rain and temperatures in the 50s and lower 60s in many locations. It might be crazy to think, but it is not entirely out of the question that it gets cold enough for the highest elevations of the Northeast, especially the Adirondacks, Green and White mountains to have wet snowflakes mixing in during the first part of the weekend.

The storm will squeeze out a great deal of moisture from the atmosphere, while drawing additional moisture in from the Atlantic Ocean. The period from Thursday to Sunday bring 4 or more inches of rain to some locations with isolated incidents of flash and urban flooding.

The storm will slowly spin off to the northeast during the second half of the weekend with improving weather conditions and rebounding temperatures. However, portions of New England may hold on to clouds, spotty rain and drizzle through Sunday and possibly into Monday morning-SS

This is the incoming line of storms. We still have some time before it arrives. It’s a good looking set of storms! There is currently a tornado warning for the Binghamton, NY area, so it is capable of spawning some nasty storms. I’ll post again as it gets closer.

Lets hope they got this guy in Boston! Stay strong! -SS

The storms and downpours are expected to increase in strength due to the building warmth of the afternoon and then remain strong into the evening.

Spotty showers will occur ahead of the line of storms and downpours during the day Friday and Friday evening. A prevailing cool wedge of air and/or clouds may limit the intensity of the storms over central and eastern New England.

Some locations can be hit by more than just a downpour and some lightning and thunder. A few places can have a severe thunderstorm that brings strong winds, torrential downpours and hail. As a result, there is the potential for downed trees, power outages and flash flooding in the vicinity of the storms.

The greatest chance of severe weather stretches from part of southeastern Pennsylvania to coastal South Carolina from late Friday afternoon into the evening.

The storms are the remnants of a squall line that affected the Central states with severe thunderstorms and flooding during the middle of the week.

It will not be until the evening before they reach most places along the middle and southern Atlantic coast and generally not until the overnight and early Saturday morning hours before they reach the east coast of New England.

There is the potential for 1-2 inches of rain along a large part of the Atlantic Seaboard later Friday and Friday night. -SS

Rain and thunder to end the week

A cold front bringing severe weather to the Midwest and the Mississippi Valley Thursday will reach the East on Friday producing rain, and locally gusty thunderstorms.

While the intensity of the thunderstorms will depend to some extent on the timing, and on how warm locations become during the day. Most locations from Florida to Maine will get a period of drenching rain. Areas most likely to experience localized strong to severe thunderstorms will be generally near and south of the Mason-Dixon line.

Some locations can be hit by more than just a downpour and some lightning and thunder. A few places can have a severe thunderstorm that brings strong winds, torrential downpours and hail. As a result, there is the potential for downed trees, power outages and flash flooding in the vicinity of the storms.

The storms will be the remnants of a squall line affecting the Central states today into tonight. It will not be until the overnight and early Saturday morning hours before they reach the east coast of New England.

There is the potential for 1-2 inches of rain along a large part of the Atlantic Seaboard. Much cooler and drier air will sweep in over much of the Eastern states this weekend. Wet snowflakes could even mix in over the highest elevations of northern Pennsylvania and upstate New York Saturday. -SS
