This little patch of showers could do something. CAMs have been adamant on at least a couple hundred J/kg CAPE in the midlevels throughout the day, with better diffluence as you head north to act on that instability. That reflects pretty well with how these showers are behaving on radar.
Storm chances will increase later tonight, especially after sunset. Instability will be low-meager, around 50-300 J/kg, but strong diffluence and shear with the approach of our offshore cutoff will be able to realize just about any instability present
