New forecast models are still showing a likely #tornado outbreak across central/northern illinois into northern Indiana tomorrow afternoon, including Peoria, Springfield, Kankakee to Fort Wayne.
Supercells could fire as early as 2-3 pm with the warm frontal mode in northern Indiana, with a main round firing on the cold front near Peoria by 4 pm. These supercells will be capable of producing EF2+ tornadoes that will be very fast-moving.
This is a high-ceiling event!
Two rounds of potentially severe storms are expected Wed, first in morning into early afternoon. These storms may produce damaging winds & large hail. A second, potentially more dangerous round of potentially tornadic storms is expected late in the afternoon into early evening.
A line of scattered storms continues to shift east across the area. While an isolated severe threat could still develop, these storms have gradually been weakening over the last hour. If storms do manage to strengthen, hail would be the primary concern. #ILwx
