Wednesday Morning Weather Update

Noon Update:  Things look pretty much on track with the forecast for today.  The slight risk has been extended a little further east to include all of northern Illinois.  We've got two broad areas of low pressure - one in South Dakota and the other in Kansas- which have helped keep showers and storms going through the morning.  Skies are beginning to clear some out in western Iowa and this is where thunderstorm development is expected to begin.  As the low in South Dakota pulls closer to the Great Lakes this evening a few storms may make their way here with gusty winds possible.  As we head into the overnight rainfall will become more likely with totals in some locations nearing an inch.  This low will quickly move out by Thursday morning leaving a brisk northwest wind and temperatures in the upper 60s.  Be sure to keep checking back as Chief Meteorologist Ty Shesky will have an afternoon update for you.


9:00am: We'll continue to see filtered sunshine through the morning and into the afternoon.  The rain moving into southeast Minnesota and Wisconsin will continue to diminish as it moves east. An area of low pressure will gain strength out in the Plains thanks to a deepening trough in the west, with thunderstorms likely to develop in Iowa this afternoon.  Rain will more than likely become widespread through the overnight with some locations receiving close to an inch.  I do believe the heaviest of the rain should stay to the north (around the low) and to the south.  Should the low shift a little further south and move more over northern Illinois that may up our totals some.  Severe weather threat with this should remain low with the greatest risk out west.  The Storm Prediction Center does have our western counties highlighted in a slight risk, I think due to the location of the low later this afternoon.  Should we see a change in our pattern today we will update you as needed throughout the afternoon!
