Sunday Morning Update

11:45am Update:  Heavy rain and thunderstorms will continue through the early afternoon.  Reports of pea to quarter sized hail have been common with the initial round of storms this morning.  Some locations that have seen repeat thunderstorms will likely have rain totals nearing an inch or greater. 

There does appear to be some clearing taking place across southern Iowa, northern Missouri and west-central Illinois.  Strong southerly winds have helped push dew points in that area close to 50° which will likely cause storms to redevelop later today as a cold front pushes east.  All of the WTVO forecast area is under a slight risk for severe weather later this afternoon with hail and very gusty winds being the primary threat.  We'll continue to monitor trends this afternoon for further clearing across northern Illinois and southern Wisconsin.  - CK

7:45am Update:  Showers and thunderstorms will continue to spread across southern Wisconsin and northern Illinois this morning.  Heavy downpours and even small sized hail could be possible with some of the stronger storms.

A cold front approaching from the west later this afternoon could allow more storms to develop.  However, the convection from this morning could keep those storms from becoming severe later today.
