Tornado Watch 001 - Issued 8:15amPDT - The Tornado Prediction Center has issued a Tornado Watch effective this afternoon into the sunset period for the Extreme Eastern IA, Northern IL, and Southern to Central WI. TPC model suggest moderate - high risk tornado dynamics in the area. Due to the lack of stronger convergence an Enhanced Tornado Watch was not issued. These storms should develop by afternoon and move Northeastward across the watch box. Additional watches will be needed further east so stay tuned...

Tornado Advisory 001 - Issued 9:00amPDT - The Tornado Prediction Center has issued a Tornado Advisory effective afternoon to past sunset. Ahead and along the frontal zone has slight risk tornado dynamics for isolated tornadoes in the area possible. The advisory box extends from Western MO through Northern IL to Chicago and ends over the lake.

Tornado Watch 002 - Issued 12:45pmPDT - The Tornado Prediction Center has issued a Tornado Watch effective this afternoon through sunset and into the night for Eastern KS to Northeastern Oklahoma on up to extreme Western MO.
Supercells developing along and ahead of the front will be capable of producing tornadoes. Some may be on the stronger side. More instability will be available in this watch box than the rest however shear is not as strong in this zone than watch box 001. Never-the-less tornadoes are possible in and around this watch box.

Description of Tornado Watch Types :

Tornado Advisory: Advisory is issued when there is a tornado chance, however weak, and small, one needs to be issued for the dynamics in place.

Tornado Watch: This watch is issued when there is either a good chance of tornadoes, a number of them, and / or a strong tornado possible.

Enhanced Tornado Watch: This watch is issued when 2 or more F3 or greater could hit and / or a number of tornadoes touching down in an outbreak fashion. This could also mean that level 4 dynamics in the output are long lasting in the same area...
