The SPC has issued a level 4/5 Moderate Risk across portions of Indiana and Illinois tomorrow with a CIG2 tornado upgrade indicating storms will be capable of producing EF3+ tornadoes. I once again say, the ceiling of this even will be dependent on morning convection and atmospheric recovery and if storms can remain isolated. If storms become more isolated and can take full advantage of this environment we are in for a LONG day of significant tornadoes. Should these turn more linear driven the risk of strong tornadoes will still be possible, they’ll just be more embedded in the line, much harder to see, and likely shorter lived.
Please make sure you have a weather plan in place. These storms will be moving extremely fast (potentially 60mph). You won’t have much time before the storms are on top of you. I will be en route this evening to get in position.
