It rained like cats and dogs last night. There is a chance for thunderstorms all morning. The 5k is on the rails to trails (asphalt) so it will not be muddy or nasty - just warm and humid. My 5k PB is 19:56 and I hope to best that time. I did an easy 4 mile run yesterday but my legs are still a little tired. I'm sure they will wake up once the race starts.
It is going to be a tough day.
