Today-Saturday ForecastJune 26th, 2013 at 11:33 am by Chad Evans under Chad's WLFI Weather Blog
Scattered storms, storm clusters & a few line segments are approaching/pass through. Very isolated wind/hail cannot be ruled out, along with torrential rainfall in heaviest storms.
The sun is out in western Illinois & actual surface cold front & subtle shortwave are in Iowa & Missouri (the stronger shortwave is in Illinois).
This will need to be monitored. Hi-res short-term data suggest new storm development & perhaps a line of storms by late afternoon-evening here as they develop near front & move eastward.
We will watch to see how this evolves & if any line can form. There is extensive capping in western Missouri, Kansas & Nebraska. If that moves east over front & overtakes shortwave, line may be a bit more difficult to form.
Front will pass tonight, rain will tend to exit.
Tomorrow & Friday, two upper troughs will pivot through along with a secondary surface cold front. This may pop a few scattered storms.
I appears a third upper trough may pivot through Saturday, while a massive ridge with record heat & wildfires develops in the West. This may pop a few scattered storms, too.
