Great Lakes region is going to get blasted Thursday/Friday. Looks like
it will be a lousy day to be on the water. The low pressure system
from the pacnw will fizzle but get absorbed by the low pressure
forming over New Mexico. That one is going to get fueled by gulf
moisture with plenty of uplift, so we'll be looking at some good
tornado weather when that rolls through our neck of the woods.

I'm not seeing how that one is going to come together yet. The
Thursday/Friday low is the one that has me concerned where I'm at.
However, if we get a hard frontal boundary form, once it hits the
dry-line, the radar is going to light up like a Christmas tree.

The Thursday low over the Great Lakes is shaping up to be pretty wild.
Any time you get the New Mexico and pacnw lows combining just west of
the Great Lakes, stuff gets nasty with surface winds approaching
triple digits out over the water and humungous waves.
