DENVER (Reuters) – A sizzling heat wave will blanket a wide swath of the Eastern United States this weekend, pushing temperatures in New York and Boston to near record highs, while Denver is bracing for a foot or more of snow, the National Weather Service said on Friday.
From Washington, D.C. to Massachusetts, forecasters say the mercury could reach in the mid-to-upper 90s. Normally at this time of year, the region enjoys cool springtime weather in the upper 60s to mid 70s, said Marc Chenard, a forecaster with the NWS Weather Prediction Center in College Park, Maryland.
In the western half of the country, a separate weather system is pushing cold air south into Colorado. Between 12 and 18 inches of snow are expected to fall between Friday night to noon Saturday, Chenard said, with temperatures plummeting from 88 degrees F on Thursday to the low 40s on Friday.
“In Denver, it’s a pretty big swing from summer back to wintry weather, but it’s not unprecedented,” he said. “So, no records are being broken. It’s just unusual.”
Late season snowfalls in the Mile High City are rare but not unheard of. An inch of the white stuff fell May 29, 1975, and a half inch dusted Denver on June 6, 1953
The threat of heavy snow has led to speculation online that this weekend’s series between the Colorado Rockies and the New York Mets at Denver’s Coors Field is in jeopardy.
Fans of the Mets, who escaped the heat with their trip out West, were not pleased by the prospect of a snow-out in May.
“If the Mets Rockies game doesn’t happen tonight it’s absolutely ridiculous,” Twitter user Elie Rubenstein wrote. “I saw intramural softball games be played in the snow, so the Mets better not use the snow as an excuse to take a vacation day.”
HIGH-PRESSURE DOME
New York City, where 73 degrees F is average for mid-May, could hit 93 degrees F on Saturday, while temperatures in Washington could reach 96 degrees or higher, he said. Temperatures should drop to normal on Monday.
Forecasters said the early season heat wave will result from a high-pressure dome of air in the upper atmosphere that is deflecting the typical flow of cool air from Canada, pushing it westward. That allows hot air from the southern and central states to move into the northeast, he said.
The National Weather Service also issued a tornado watch for Maryland, Delaware, New Jersey and parts of southern Pennsylvania from midday on Friday and to 7 p.m. A watch means that conditions are favorable for the formation of a tornado.
