[Guest]

Strong to severe storms are now begining to fire up in southern Michigan and Northern Indiana and are headed off to the ese. SPC has issued a meso for it and a WW could and will probably soon be needed as the storms continue to grow and expand as they head for OH and western PA later tonight. Main threat looks to be damaging winds and as well large and damaging hail to a lessor degree. EDIT a watch has been issued as i type this.
