A Surge of Warm Air Moves into the QC...

It's going to be a chilly weekend with temperatures about 10 degrees below average. However, on Monday temperatures will climb into the 70s and stay in the upper 70s for much of next week. So why are temps going to above normal for much of next week?

Well, next week there's going to be a trough in the jet stream (which is the upper-level winds in the atmosphere) in the Western U.S. and Eastern U.S. with a ridge located in the middle of the country. This is known as an omega block, because the winds take the shape of the greek letter, omega! An example of what the winds would look like according to the weather models in an omega block is shown below.




So this wind flow pattern means that warm air will flow into the Quad Cities from the South for much of next week until the winds in the upper-levels of the atmosphere shift.
