AccuWeather has it at the infamous 51% probability level for thunderstorms at 5 CST, so there’s still a decent chance for success tomorrow.

Time will tell!

The percentage isn't the percent of it occurring but the area affected. So 51% of thunderstorms means 51% of that town/county/etc. will experience thunderstorms.

the real question is what is our probability of Launch Commit Criteria Violation at T-0. i've seen them be no go at t-10 with a 10% chance of go and watched it lift off on time.
