Severe Storms VERY Possible Across OHIO SUNDAY AFTERNOON

The Storm Prediction Center has painted OHIO in a Moderate Risk for Severe Storms SUNDAY. To give you an historical reference point to what this means, OHIO usually goes under a MODERATE RISK only a few times a year. Bottom line, don't take this threat lightly.




Remember, a SEVERE THUNDERSTORM is a storm with 58 mph winds AND/OR 1" hail or a tornado. When any one of these criteria are met, a SEVERE THUNDERSTORM WARNING is issued.

Here are the meteorological parameters for tomorrow:

Super strong jet stream...left front exit region over Lake Erie

Upper level diverging air at 500mB (18,000 feet) which translates into rising air at the surface.
Pocket of HIGH surface winds across northern Indiana and Ohio exceeding 40-45 mph.
. Sharp temperature gradient...

Expect a fast moving squall line (embedded severe storms) late Sunday afternoon into the early evening Sunday. The timing a strength of the line of storms will need to be monitored.
