Folks out west in the Great Plains will get a break from the severe weather threat, as storm chances will now be located around the Ohio Valley and areas to the northeast.

A severe weather outbreak is not expected, but a few strong to severe storms possible this afternoon with damaging winds and hail the main threats.  A cold front crossing the area will be triggering these showers and storms, with the highest threat from 2-8pm today.  Storm activity will diminish around sunset. 

Notice with the following four maps, the highest threat of severe storms will be northeast in Ohio.  The tornado threat is small, but still larger in Ohio.  The wind and hail threats are similar and both higher of course in Ohio.  One big reason for the higher severe threat in Ohio is that's where there is a larger acceleration in winds.  Notice the last map and the jet (strong winds) aloft at about 18,000 feet.  This shear can keep storms strong, and also help produce damaging straight-line winds.

Notice also the northwest flow out to our west.  Cooler and drier air will be moving into our region as a result this weekend.
