22S Ilsa, 21P Ken and Chase Forecast: 03/22, 03/23

The naysayers are out in full force again! Maybe I'm a "yaysayer" because I know that I'll be able to chase the upcoming forecast setup. Either way, things are looking good. Most of the attention is on Monday as we have a nice, deep trough carving its way eastward with a bit of a negative tilt to it. The models are showing some great shear, decent moisture & instability, and some good dynamic forcing in place. The word "squall line" often comes into play in situations like this ... especially by the naysayers. However, I think we will slow down a bit and see some supercells before we get wiped out. Now, here's the kicker:

I think Sunday is the sleeper day. The GFS, which has been underestimating instability all year long, is painting a nice window in Nebraska and Kansas. The only caveat is the inhibition. I believe that the western edge of the cap might break and though the shear won't be nearly as good as the next day, we could still get some explosive, rotating updrafts. Hail, isolated tornadoes look like a plausible threat. The SPC isn't even talking about this day but I'll definitely be keeping my eyes on it.

Looks like I'll be heading out for both days. Still trying to get everything coordinated at this point, but if anyone is looking to get out, don't be a stranger!

Also ... looking like there might be some thunderstorms in the forecast for Western Montana on Saturday!
