The jet stream is shifting around and will bring a welcomed change to the weather in the coming days.
A persistent dip in the jet stream – an upper level trough – has been positioned over the Great Lakes and Northeast in recent weeks, promoting cool temperatures and unsettled weather and preventing much in the way of widespread warm, summer-like air.
That dip in the jet is in the process of lifting out of the region and will be replaced by a more typical summertime upper level ridge, with an accompanying surface high pressure setting up along the Eastern Seaboard. The “Bermuda High” will result in much warmer temperatures over the eastern half of the nation.
You’ll notice the change in the air beginning Saturday as west winds kick in and temperatures climb into the 70s. And true summer warmth will arrive for the second half of the weekend and into the first part of next week as readings climb to the 70s and 80s.
