Severe Thunderstorms Possible Wednesday


The SPC in Norman has placed much of Ohio and southern Ontario (if extrapolated) in a Slight Risk of Severe storms. However, some rather significant severe weather is possible, depending on what happens during the morning hours tomorrow. The SPC expects thunderstorms to be in the area in the morning, which will weaken and eventually die off. This will allow for moderate destabilization with MLCAPE reaching about 3000J/kg by mid afternoon. This combined with shear around 35-40kts will allow for good storm organization to occur.

Storms are expected to be supercells as the develop during the mid afternoon, and eventually form into bowing segments. Some isolated tornadoes are possible, and you can see that clearly as the GFS is depicting large, curved hodographs:
I will be able to update at least once tomorrow to give a brief summary of what's going on, but I won't be able to do much other than that. Stay tuned to the Storm Prediction Center and the National Weather Service for more information and watches/warnings throughout the day tomorrow!
