The Storm Prediction Center issued Tornado Watch 313 until 02:00Z, replacing Watch 311 for portions of the Midwest and Great Lakes, including areas in the MKX and ILX forecast regions. SPC's Mesoscale Discussion 1091 assigned a 40 percent probability for a watch and identified the most likely hazards as 1.00 to 1.75 inch hail and wind gusts of 55 to 70 mph. The watch signals an organized severe storm threat, including tornadoes, very large hail, and damaging winds, across populated counties, so residents in affected areas should monitor local warnings and be prepared to take shelter.
