Northeast Memorial Day Weekend to Start Wet, Chilly
State College, Pa. — 22 May 2013 — AccuWeather.com reports the Memorial Day weekend will begin cool, windy and rainy in New England and part of the mid-Atlantic.
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.
Similar to a storm developing along the coast during the winter, a swath of steady rain and localized thundery downpours will develop from part of the Delmarva Peninsula and Pennsylvania northeastward to Maine from Thursday evening on.
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 from portions of northern New Jersey, eastern Pennsylvania and eastern New York state to northern New England with a driving wind, rain and temperatures in the 50s and lower 60s in many locations.
According to Expert Senior Meteorologist Henry Margusity, “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.
According to Expert Senior Meteorologist Brett Anderson, “The period from Thursday to Sunday bring 4 or more inches of rain to some locations with isolated incidents of flash and urban flooding.”
Anderson is especially concerned about flooding in areas that have recently received rain.
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.
West and south of the storm system, from western New York to Virginia, breezy and cool conditions are in store for the first part of the weekend with intervals of clouds, sunshine and spotty showers. The last part of the weekend will trend sunnier and warmer.
