An active jet stream sets up an active storm pattern that moves across the heartland of the US and causes several days of extreme weather from Monday through Wednesday.
Before the storm, gusty winds in excess of 50 mph increased Arizona's forest fires to Texas and Minnesota.
The first storm system to propel this jetstream will bring a flood of thunderstorms Monday from the Dakota to West Texas. The biggest threat from today's storms will be the wind and hail, and there is little chance of a few tornadoes.
The good news today is that the worst of the storms will be mostly in the open plains where few people live.
On Tuesday, the threat of flooding will increase with increased risk for cities, including Omaha, Nebraska issued. The biggest threat is caused by damaging winds, hail and a few tornadoes. The tornado threat will be slightly higher on Tuesday.
Affected areas, including Omaha and parts of Kansas City, will be affected.
An even stronger storm system will take the jetstream from the west to the plains at Wednesday, an even greater threat of tornadoes, damaging winds and hail in populated areas, such as Abilene, Texas; Oklahoma City; Wichita, Kansas; Kansas City, Missouri; and as far north as Des Moines, Iowa.
Before the Heavy Weather Will it suddenly feels like summer for the Midwest and Northeast.
Monday's temperatures will be up to 20 degrees above normal for the Upper Midwest and Plains, with temperatures near 80 degrees in Minneapolis. The area had snow a few weeks ago and the lakes are still frozen.
The unusually warm air will move to the northeast and the east coast on Wednesday, Thursday and Friday with some areas of Washington, DC to Boston can reach 90 degrees.
By the end of the week, record highs are possible in the Northeast. Better that the air conditioning is installed.
