Severe Threat Once Again


Looks like round number two...or should I say three...will move in through this evening and overnight.  The slight risk for severe weather continues for all of the WTVO viewing area while the far northwest part of Illinois has now been added into the moderate risk.  While skies will remain mostly to partly cloudy this morning...there is some clearing to the west through Iowa behind this system.  With the stationary boundary to the south the atmosphere will remain fairly unstable through the afternoon and any little outflow boundary or upper level disturbance will help generate storms.  While we do have the potential for storms this afternoon, I think the big threat will come in the evening and overnight as storms that will develop off to the west merge together to form another linear complex.  I'm starting to get a little concerned about the potential for another damaging wind event tonight.  We'll continue to monitor things in the weather center and try to get another update later this morning.
