Impressive Fall Storm System This WeekendOctober 9th, 2012 at 5:31 pm by Chad Evans under Chad's WLFI Weather Blog
An impressive fall storm system will deepen to high-end tropical storm surface pressure this weekend in the western Great Lakes. Very strong winds at all levels, as well as directional & speed shear with support severe weather event/outbreak from Texas to Wisconsin to Kansas & Iowa.
Higher tornado threat will evolve on triple point to our west. Otherwise, wind & hail would be the main threat to our west with a few tornadoes. Supercells will tend to congeal into a cool-season QLCS squall, which will race eastward late Saturday into Saturday night.
Evolving QLCS squall line may last long enough, given strong low-level jet & upper support (despite waning instability, especially surface instability) for damaging wind threat in the western half of our viewing area early Sunday morning.
We will watch & tweak forecast as we get closer to the weekend.
