Severe Storms Weakening

Although there is still a Severe Thunderstorm Warning in effect for southern Whiteside county until 12:15am, radar trends and upstream reports indicate that the potential for severe weather is ending this morning. Although we've seen warnings popping up along and west of the Mississippi River over the past couple of hours, the hail reports with these storms have generally been for 1/2" diameter hail or less. (To meet severe criteria, hail must be 1" diameter or greater.) Winds have generally been less than 50mph, well below severe thresholds of 60mph.

It also appears that the heaviest returns with this line of storms are dissipating and becoming less-organized. Therefore, most areas will see brief, heavy downpours, small hail, and winds gusts approaching 35 to 40 mph as these storms move through. Rainfall amounts may exceed 0.5" in some cases.
