States across the U.S will experience bizarre weather over the next few days but while the east coast prepares for heavy snow, thunderstorms, and lashing rain the Southwest is in the middle of a sweltering heat-wave.
Winter weather, including possible tornadoes and snow, will pummel the Atlantic seaboard, delaying the space shuttle Enterprise’s trip to New York and potentially causing floods and power cuts.
Meanwhile in the Desert Southwest residents are experiencing record-breaking temperatures hitting the high 90s and triple digits today and tomorrow.
Heavy rain that hit Florida in the last few days is moving north and is expected to meet with cold air coming south from Canada.
Delaware, New Jersey and Pennsylvania experienced thunderstorms on Saturday night but forecasters have predicted the worst of this spring storm is yet to come.
‘It’s going to be a very, very intense Nor’easter,’ forecaster Michael Eckert, from the National Weather Service based in Camp Springs, Maryland, told Msnbc.
Snowfall is expected across the Appalachians in West Virginia and central Pennsylvania tonight before it heads to the Buffalo, New York, area on Monday.
Experts have warned that the snow is likely to be heavy and wet making tree and power line damage a likelihood.
NASA announced that the Enterprise’s journey to New York’s Intrepid Sea, Air and Space Museum is being re-scheduled because of the unseasonal storms.
The trip involves the shuttle being attached atop a carrier aircraft and then moved by barge for the final leg of the journey.
Forecasters say two to three or even four inches of rain will be coming to parts of eastern Pennsylvania and northern New Jersey tonight through early Monday.
Meteorologist John Darnley says the storm’s biggest threat is likely power outages caused by falling trees and limbs bringing down power lines.
Meteorologist Greg Heavener of the National Weather Service says some local flooding is possible along smaller rivers and creeks.
In the west, forecasters say the storm could bring 8 to 12 inches of snow to higher elevations in Fayette, Westmoreland, Indiana and Jefferson counties and three to four inches in Pittsburgh and surrounding areas.
Meanwhile Mother Nature is bringing soaring heat to cities including Phoenix, Yuma and Las Vegas tomorrow.
Typically the first 100-degree reading in Phoenix comes around May 2 but that mark is expected to be reached tomorrow.
The unusually hot weather is also spreading into the Sacramento and San Joaquin Valleys of California and Oregon could have record high temperatures too.
