The weather folks call a large area of thunderstorms a mesoscale complex of storms. We get them occasionally, and some can be very strong. We have one approaching, which at this time appears to not be real strong in our area. That can change, and the outflows from the storms can create stronger storms as the system moves.
From what I can see, the system will arrive just about the time when a children's birthday party will start down the road. Hopefully, they don't have to deflate the inflatable water slide, and seek cover. Yesterday would have been a better day, but hindsight always shows such things.
They system died out before it reached us and we only received some high clouds. The children's party was a success and everyone had a good time.
