SEVERE WEATHER UPDATE: Sunday NOON UPDATE

Everything is still pointing to a HIGH POTENTIAL for severe thunderstorms THIS AFTERNOON AND THIS EVENING.

TORNADO WATCH ISSUED FOR NORTHERN INDIANA, FAR WESTERN OHIO UNTIL 8PM


Remember, a SEVERE STORM 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. A TORNADO OR SEVERE THUNDERSTORM WATCH means conditions are favorable. WARNING means its occurring now!

RADAR SNAPSHOT AT OF 11:30AM

Plenty of sunny breaks which will only destabilize the atmosphere which will promote more storm development. Visible satellite image here...


The discussion posted here yesterday still holds:

High resolution HRRR model brings the main line of strong/severe storms into western Ohio by 6PM...8PM across northern Ohio


Storm Prediction Center has shifted the MODERATE and HIGH RISK area further east. HIGH RISK now in western Ohio!!!

To put this into perspective, Ohio is put into a HIGH risk SEVERE WEATHER area about once every 3-5 years. 

Tornado chances seem higher in Illinois and Indiana
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.
A very large temperature gradient. Sunday morning temperatures are already pushing 60 across northern Ohio
All of these conditions will produce very strong winds at the surface in excess of 40-45 mph later today.
