Capital Weather Gang NatCast has 'While warmer, still an overall pleasant game night.' with high of 82 and low of 78, chance of rain nil. If you want to take in any of this Rays series and aren't too crazy about beastly-hot days, better go to this one...they're estimating 96 for tomorrow and 99 (with 20% chance of rain) for Thursday.
One nice thing though: it's a weeknight series so no major Metro track work.
