Mixed May in U.S.: From temperature roller coaster to snowStaff Writer | April 30, 2017
The temperature roller coaster ride in the northeastern United States will continue on Monday, setting the stage for severe thunderstorms over a part of the region.
Weather The stage for severe thunderstorms
Cooler air pressed into the Northeast on Sunday, holding temperatures 15 to 25 degrees below Saturday's highs in many communities.
The change was even more dramatic in Boston. After coming close to breaking Saturday's record high of 85 F, temperatures were about 40 degrees lower on Sunday afternoon.
An exception to the cooldown on Sunday was the southern mid-Atlantic and locations along and west of the central Appalachians, where the next warm surge has begun.
Along the boundary separating the warmth and cooler air, spotty thunderstorms will erupt from western Pennsylvania to northern Virginia into early Sunday evening. One or two of the thunderstorms can produce strong wind gusts.
On Monday, temperatures in much of the mid-Atlantic and central New York will climb into the upper 70s and 80s due to strong southerly winds.
Exceptions to the warmth on Monday include the south-facing shoreline areas and eastern New England due to wind blowing off the cool water. Temperatures will be held to the 40s in Portland and Bangor, Maine.
Severe thunderstorms capable of causing property damage and flooding will continue to target communities from the southeastern United States to the Ohio Valley into Sunday night.
A storm will finally make eastward progress early this week after dumping flooding rainfall and triggering damaging thunderstorms for several days over the Central states.
Into Sunday evening, the most intense thunderstorms will continue to advance across Alabama and into northwestern Georgia. Severe thunderstorms will also erupt across Tennessee during this time.
“With plenty of heat and humidity to tap into, these storms will be capable of producing damaging winds and hail as well as a few tornadoes,” AccuWeather Meteorologist Faith Eherts said.
“A very strong spring storm cutting northward through the Plains is dumping a narrow swath of heavy snow on its western side,” AccuWeather Meteorologist Jake Sojda said.
The same storm was responsible for the deadly tornadoes in northeastern Texas and the rising rivers in the Mississippi Valley.
After proving to be a boon for the ski resorts in the Rockies, the snow will continue to sweep from western Kansas to Minnesota through Monday.
“Several inches of wet snow will blanket places like Goodland, Kansas, and Kearney, Nebraska, before pushing northward to Watertown, South Dakota, on Sunday night into Monday morning,” Sojda said.
Snow can exceed a half a foot in western Kansas and central Nebraska. Snow will also spread over western and northern Minnesota Sunday night into Monday, whitening St. Cloud and Duluth. ■
