cyclone77 Posted April 25, 2016 Share Posted April 25, 2016 Cu field here at home is starting to take off decently. Showing some modest vertical build. Should really take off over the next hour. Storms should fire up very close to here next hour or two. EDIT: Looking at vis, looks like a prefrontal zone of convergence is lining up from extreme NW IL down to a little west of DVN. That may be what fires in a little while. Link to comment Share on other sites More sharing options...
nwohweather Posted April 25, 2016 Share Posted April 25, 2016 Not a bad day for everyone in the slight risk, could get some interesting winds with that LLJ as well as large hail as this system organizes. Of course it'll be too late in the day for me by the time it gets here but that MCS should be cooking thru SW MI and Northern IN Link to comment Share on other sites More sharing options...
cyclone77 Posted April 25, 2016 Share Posted April 25, 2016 From a chasing standpoint, I think I'll play the southern end of the line. HRRR has been fairly adamant about that being around the I-80 corridor. That plan may change though once things fire and we see how things shake out.

cyclone77 Posted April 25, 2016 Share Posted April 25, 2016 Fairly broad 1500j/kg+ cape showing up on SPC meso extending up to about the QC. Little blob of 2000j/kg over northeast MO. Still on the increase as well. Mid-level lapse rates are exceeding what was forecast a few days ago, so the hail threat is considerably more than what I was thinking back then. Cu field continues to look increasingly impressive here. Nice lean to them as well. About go time. Link to comment Share on other sites More sharing options...
