Severe Weather Today

The Storm Prediction Center has placed most of Northern and Central Ohio in a slight risk for severe storms today. The main threat will be damaging winds, along with some isolated severe hail reports. The tornado threat today appears very limited right now, but one or two tornadoes can't be ruled out. It appears that one or two MCS (Mesoscale Convective Systems) will be developing later today, moving ESE through the 30% wind risk zone. A very unstable atmosphere characterized by SBCAPE in excess of 3000J/kg, along with DCAPE in excess 1200J/kg, should allow storms to become severe, and produce damaging wind gusts. Steep Lapse rates should at least produce a few scattered hail reports, but an elevated freezing level will keep the number of reports down a bit. Storms are expected to develop by 18-20z (2-4PM), and last into the early nighttime hours.

Stay tuned to the Ohio/Ontario weather blog, along with the SPC and your local NWS weather office for any additional updates. I will be online for most of the afternoon.
