Strong and gusty thunderstorms will roar through portions of the eastern Great Lakes, Northeast, Dakotas and Minnesota today into tonight.
Gusty Thunderstorms for the Northeast
After a week full of unsettled weather, another round of showers and thunderstorms will cross through parts of New York, Pennsylvania and New Jersey today.
These storms will fire and ride along a nearly stationary cold front which will be draped across the region. As warm air surges northward towards the front, showers and thunderstorms will develop.
While a widespread severe weather outbreak is unlikely, a few of the thunderstorms will be strong to perhaps severe producing gusty winds and hail from Lake Ontario to the New York City area and southwestern New England.
Cities which may be impacted by these storms today include Buffalo, Syracuse, Scranton and Allentown.
Those planning on attending the Belmont Stakes outside of New York City this afternoon and evening in Elmont, N.Y., will lie in the path of these storms.
The threat for severe weather is expected to end across these areas shortly after sunset.
Strong Storms to Rattle the Northern Plains
Just a couple of days after severe storms rocked portions of the northern Plains, another potent storm system sliding out of the Rockies into the northern Plains and Canadian Prairies will bring more strong storms to the region.
Unlike the Northeast, the majority of the day will remain dry across the Dakotas and northern Minnesota.
Most of the activity will not begin to fire until late in the afternoon and evening as hot and humid air surges northward ahead of a cold front sliding into the western Dakotas. After the storms fire, they will continue to track eastward throughout the course of the night.
These storms will have the potential of producing damaging winds capable of causing damage to trees, power lines and homes. These storms will also produce large hail which could damage crops across the region. It is not out of the realm of possibilities that the strongest storms could spawn a tornado.
Cities which will be at risk late this afternoon and evening include Bismarck, Fargo and Grand Forks. Towns and communities in northwestern Minnesota and the eastern and central Dakotas will have to contend with these storms through the night.
On Sunday, the focus of these strong thunderstorms will shift to the east into the Midwest affecting Minnesota, Iowa, Wisconsin and parts of eastern Nebraska and northeastern Kansas. Damaging winds and hail will once again be the primary threat on Sunday.
A pattern favoring waves of progressively cooler air will set up across much of the Midwest and Northeast during next week and could continue into early May.
Round after round of drenching rain will continue to cause flooding in the South, while another dose of rain may renew flooding in the Ohio Valley this weekend.
The 119th Boston Marathon will take place on Monday, April 20, and runners set to take on the historic course will face cool and rainy conditions.
Thunderstorms with the risk of damaging winds, hail, isolated tornadoes and torrential downpours will begin to shift eastward over the central United States this weekend.
In a high-tech world of satellites, computers, mobile devices and wearables, the weather balloon is still an important tool which helps meteorologists create more accurate forecasts, especially in the case of severe weather.
Rounds of flooding and severe storms slammed the South and Plains this week, while a storm system unleashed dust storms and snow in the West.
