TSS posted on their Facebook page that things are still on for tomorrow - I don't think anyone could have stated it better:

Tri-State Speedway- "The Class Track"
Yes it's hot and yes we are still going to run on Sat. night. Please use good common sense and don't come at 4:00 to sit in the hot sun. There will be plenty of seats for everyone. Remember that hot laps (and we mean really hot) will start at 6:30 followed by racing at 7:30 PM. Stay hydrated and dress appropriately please. Everyone is hoping for a break in the heat and dry weather! Yes we do need rain very badly. You know it's bad when a dirt track is needing rain in order to survive.

I'm sure Tom needs the rain for the crops and let's all say a prayer that we get a non racing day rain break soon!
