My thoughts for the next 48 hours from storm chasing perspective: I'm ho-hum about today/tonight. But heading out to Eau Claire area anyway and hopefully things light up. Focused mainly on Sunday. This morning model runs became uncertain about whether upper level support and possible MCS will move through at the best time for Wisconsin. In otherwords current models show upper support rolling though Wisconsin at around 1PM. This won't allow things to tie together and the setup becomes awkwardly disjointed between mid day and late afternoon setups, the late day one I'm wouldn't be thrilled about because of inversion. I'm not buying it yet, sometimes we see things happen close to the day 3 prog. I stand by my word that if things come together tomorrow, there will be a significant weather event. Chances of that are best when instability, 850mb, 700mb, 500mb all line up. Best way to approach it is to get out there and figure it out later. Trying to bottle up all the ideas into neat categories could cause you to miss a major event because you thought MCS, and what actually happened was dominant supercell.

Seeing reports of Non-storm related wind damage in extreme northern WI. today. Anyone on here in those areas seeing this? Please share...
Progressive derecho possible tomorrow. If not, could have tornado outbreak during the afternoon. Either way not good.  www.spc.noaa.gov/misc/AbtDerechos/casepages/jun292012page.htm
Email warning alerts were turned off this morning due to a failure yesterday. Will investigate. In my personal inbox I had 14 Severe Thunderstorm Watch notifications. Not the intended experience. My apologies.
