Occasional downpours to dampen Memorial Day weekend activities

AccuWeather Global Weather Center — May 25, 2018  —  AccuWeather reports while people in the Northeast will have to dodge showers and thunderstorms from Saturday to Memorial Day, the holiday weekend will not be a complete washout.
 
Showers will riddle the area over the holiday weekend, but people should plan on the idea that most of the time will be rain-free, according to AccuWeather Chief Meteorologist Elliot Abrams.
 
The area of high pressure that brought the recent stretch of dry conditions will settle off the Atlantic coast this weekend, allowing storminess to return to the mid-Atlantic and New England.

Downpours may force people attending cookouts, parades, memorial services and other holiday activities in Pittsburgh, Philadelphia, Washington, D.C., Baltimore and New York City to run for cover on occasion.
 
Following widely scattered storms on Saturday, downpours will increase along the Interstate 95 corridor from Saturday night to a portion of Sunday. This may prove to be the wettest period during the holiday weekend.
 
Enough dry air may punch into the central Great Lakes and Ohio Valley for wet weather to be kept at bay in Detroit and Cleveland on Sunday, following the potential for a storm or two on Saturday.
 
During a busy weekend for outdoor activities, be sure to head inside as soon as you see dark, billowing clouds and hear thunder to avoid the risk of being struck by lightning.
 
Motorists traveling along area interstates should anticipate delays due to the damp conditions and increased holiday traffic. Flight delays may occur as storms wander over the major airport hubs.
 
Localized flooding will be possible, especially where an abundance of rain has fallen so far this month and storms hit repeatedly over the weekend.

It will take less than an inch of rain in one hour for flash flooding to ensue across much of the mid-Atlantic. 
While moisture from the Gulf of Mexico will help to enhance the downpours across the Northeast, the heaviest rainfall and highest flood risk associated with Alberto will remain farther south into early next week.
 
In addition to needing umbrellas on occasion, residents and visitors across New England will need to pull out extra layers by Sunday.
 
“A cold front from eastern Canada will slip southward through New England, leading to cool and damp conditions in Providence, Rhode Island, Boston and Portland, Maine, on Sunday,” Abrams said.
 
People in Boston will be trading in shorts with highs in the middle 80s F on Saturday for jackets with highs failing to crack the 60-degree mark on Sunday. The cooler air will even progress into New York City, where highs will drop from near 90 to near 70 during the same time frame.
 
Temperatures will not dip as severely farther south and west.

Memorial Day may mark a slight moderation in temperatures across southeast New England and also turn out to be the driest day of the holiday weekend in the Northeast.
 
The push of dry air that will likely keep the central Great Lakes and Ohio Valley rain-free on Sunday is expected to spread into the Northeast by the holiday.
 
“Showers will tend to be more spotty on Memorial Day,” Abrams said.
 
The forecast looks promising across most of the Northeast, including the I-95 corridor. Advancing showers in northern New England and spotty storms in the mid-Atlantic may only bring brief interruptions to outdoor plans.
 
The mainly dry weather will likely hold into Tuesday as people head back to work and school.
