There's something different about baseball compared to any other sport: Weather plays a key role in the results every single day.

Whether the forecast shows high winds or cold temperatures, there are plenty of variables that can either strengthen or weaken an offense and help or hurt a pitching staff.

Every day, we're keeping an eye on the weather forecasts around MLB, and when the weather makes a difference in our betting for the day, we're here to share our best bet based on the forecasts.

It's officially the start of summer, and we've got temperatures across the MLB landscape that prove it. We know that hotter it is, the thinner the air is, and the farther a well-hit ball will travel, so as we enter summer months we tend to see more runs scored than what we do at the start of the MLB season.

The standout weather game for bats today is in Philadelphia, where the temp is in the low 90s and winds are blowing out to center at near 10mph. In 32 similar weather games we've seen an increase of 37% to homeruns, and a 15% increase to runs scored. It may come as no surprise that my favorite weather bet of the day is Over 10 runs in ARI @ PHI.

Pick: Over 10

A few showers lingering early, likely gone by first pitch, but a late start isn't out of the question.

If we fully trust high-res forecast models this far out (and to be clear, we don't), a grouping of showers/storms will miss NY just a few miles north. This would allow them to play without issue. If that cluster of storms comes in a few miles farther south, it would cause some sort of delay. I'll leave it YELLOW on our green/yellow/orange/red scale for now and see how radar looks before first pitch.

Any spotty showers should stay clear of the ballpark.

A few storms, generally fading as they move closer to Denver. I'll leave it YELLOW for a chance of a delay, though it's not something I'm worried about for bats.
