Strong Thunderstorm to Race Across Plains, Upper Midwest

An active couple of days will bring strong to severe thunderstorms to central Plains this afternoon and then target the northern Plains and Upper Midwest during the day on Saturday.

A slightly complex weather pattern will set up across the nation's interior and once again along the United States-Canadian border and will set the stage for the active weather this weekend.

"The front that pressed into southern Texas yesterday and helped to bring more than 4 inches of rain to Weslaco, retreats back north again today. This front will stall out along the Texas-Oklahoma border, allowing for gusty thunderstorms to develop along it", said AccuWeather Meteorologist Courtney Spamer

The strongest of these thunderstorms will begin to develop during the middle of the afternoon, becoming a line of storms that will move southeast and bringing damaging winds and hail to the southern Plains.

Hail can be large enough to cause some damage to property, while winds can knock down trees and power lines.

Although there will be some strong thunderstorms on Friday afternoon, the main severe weather event will hold off until Saturday.

A more potent storm system straddling the Canada-United States border will be the forcing agent behind the strong storms that fire during the first half of the weekend in the northern Plains.

This system will dive south across Montana and North Dakota during the afternoon, bringing a cold front that will slice into a warm and unstable atmosphere.

The interaction between this front and the unstable air mass will give way to strong afternoon thunderstorms, capable of becoming severe.

AccuWeather Meteorologist Steve Travis states, "A strong cold front will move across the Upper Midwest and Plains Saturday, bringing strong thunderstorms from Minnesota through Iowa."

This system will continue to strengthen as it moves across the northern Plains during the afternoon and will bring the strongest storms to Fargo, North Dakota; and Omaha, Nebraska, during the first part of the afternoon, while holding off until the late afternoon and evening for Minneapolis.

"The strongest storms will fire up in the afternoon, continuing into the evening hours. The main threats will be large hail and damaging winds; however, there may also be a few tornadoes", continued Travis.

The second half of the weekend will have the threat for severe weather diminish as this system moves on to impact the Northeast on Sunday and into the next workweek.

As this system departs, cooler air will be brought in from the north and conditions will become increasingly breezy on Sunday.
