A Top Ten……T’Storm Outlook For Tonight-Wednesday MorningJuly 22nd, 2014 at 12:11 pm by Chad Evans under Chad's WLFI Weather Blog
I am still working on these top ten lists. Delphi is finished, however.
It is a hot one! Heat Advisories are as far east as western Illinois.
Temperatures are surging well into the 80s across the viewing area with dew points in the upper 60s to lower 70s.
Segment of stronger upper flow will branch off & nose into Iowa & Illinois this evening (notice new NAM model data below showing a southerly extension or arm of stronger westerlies). This has caused an expansion of severe weather threat area into our viewing area tonight-tomorrow morning.
Given the residual heat/instability (though it will be waning) & a bit more southerly stronger flow aloft, potential of t’storms organizing into a cluster or two or possibly an MCS/line exists. Scattered strong-severe gusts are possible. A bit of hail cannot be ruled out.
