CUmet Posted May 25, 2011 Share Posted May 25, 2011 Although I had previously written these off an hour or two ago, surface observations and radar trends suggest the threat associated with the cells into east-central AR cells is increasing. Surface winds at Jonesboro, West Memphis, Stuttgart, and Pine Bluff are all at 190 and significantly more backed than recent hi-res model runs. Tightening couplets on radial velocity support the idea that there is actually more helicity than is currently being diagnosed/forecasted by these models.

OHweather Posted May 25, 2011 Share Posted May 25, 2011 Looks like things could get interesting here in NE OH as the evening wears on. QLCS type squall line moving in from the west with multiple tornado warnings. We are sitting in the upper 70s with dew points in the upper 60s, which is supporting marginally low LCLs of below 1250m per the SPC mesoanalysis. Surface winds have a definite easterly component to them and the low level jet is slowly strengthening, supporting increasing effective helicities along and just ahead of the squall line. Given 1500-2000 J/KG SBCAPE ahead of the squall line (and slowly increasing MLCAPEs) along with 40-50 knots of deep layer shear and 20-30 knots of low level shear along and just ahead of the squall line, I don't think we will see any significant weakening of the squall line until the sun goes down at the earliest, so I have a feeling the Cleveland area will get hit hard with scattered damaging winds and maybe a tornado or two. There is some discrete stuff firing up near Mansfield, OH which is currently non-severe, however if it can stregnthen it may pose a tornado threat before getting absorbed into the squall line. All I know is I work at 8:30, which may be right around when things get bad here on the east side of Cleveland, and I hope that if there is a tornado warning people don't disregard it after the false alarm that affected a lot of population two days ago here.
