MLB Games to Monitor for Weather
Giants at Cardinals (7:45 p.m. ET)
Weather Risk: MODERATE
Thunderstorms are the primary concern at Busch Stadium, where precipitation probability peaks at 63% around 8:00 p.m. ET. Scattered storms are expected to develop during mid-game hours before gradually easing later in the evening. The game should start on time with storms building after first pitch, though an interruption remains plausible if cells move directly over the ballpark.
First-pitch temperatures near 96°F add another element, with conditions cooling into the mid-80s as the evening progresses.
Weather Timeline
- 7:00–7:45 p.m. — Storms developing to the west; first pitch window appears manageable at 28%
- 8:00–8:30 p.m. — Peak thunderstorm probability at 63%; highest risk of an interruption
- 9:00–9:30 p.m. — Storm chances ease to 37% as cells push east
- 10:00–11:00 p.m. — Lingering 35–38% chance keeps conditions unsettled through the late innings
Braves at Cubs (7:40 p.m. ET)
Weather Risk: MODERATE
Scattered thunderstorm chances persist throughout the evening at Wrigley Field, with probability hovering between 21% and 32% across the entire game window. Northwest winds at 10 mph create a crosswind that could affect fly-ball trajectories. Unlike St. Louis, no single hour shows a dominant storm threat; isolated cells may produce brief interruptions at any point during the game.
Forecast confidence remains moderate given the scattered nature of these storms.
Weather Timeline
- 7:00–7:40 p.m. — Thunderstorm chances at 32%; highest probability of the evening
- 8:00–9:00 p.m. — Brief dip to 21% before rebuilding to 25%
- 9:00–10:00 p.m. — Chances increase to 30% as a secondary round of cells approaches
- 10:00–11:00 p.m. — Storms continue at 25–29% through the late innings

- Marlins at Diamondbacks (9:40 p.m.) — Chase Field’s retractable roof is expected to be closed due to monsoon thunderstorms and extreme heat. No concerns inside.
DFS and Betting Weather Notes
Giants at Cardinals
The 63% thunderstorm peak during mid-game creates meaningful uncertainty for DFS lineups and betting totals. Starting pitchers face potential shortened outings if weather forces an interruption, increasing bullpen exposure and volatility. Extreme heat at first pitch (96°F) modestly favors offensive production early, but deteriorating conditions could limit late-inning scoring. Monitor the forecast closely before lock and consider the weather risk when evaluating game stacks.
Braves at Cubs
Wrigley’s 10 mph northwest crosswind creates unpredictable fly-ball behavior, and the persistent 21–32% thunderstorm threat adds roster construction risk throughout the game window. The steady storm chances without a clear window of improvement make this a game where weather could intervene at any point. DFS players should account for the possibility of an interrupted contest when building lineups around this matchup.
FAQs
What MLB stadiums have retractable roofs?
Seven MLB stadiums feature retractable roofs: Chase Field, Globe Life Field, Daikin Park, loanDepot Park, American Family Field, Rogers Centre, and T-Mobile Park. These venues can close their roofs during rain, extreme heat, or cold weather, effectively eliminating weather risk. Roof status is typically determined hours before first pitch based on current and forecasted conditions.
How does wind affect MLB betting totals?
Wind direction matters more than wind speed when evaluating totals. Outward wind (blowing toward the outfield) can improve fly-ball carry and slightly increase scoring potential, while inward wind suppresses home runs and may create a modest pitching advantage. Crosswinds produce less predictable results. Sustained winds above 15 mph at hitter-friendly parks can create value on totals.
Do over/unders move when rain is in the forecast?
Sportsbooks occasionally adjust totals when significant rain threatens a game, though movement is usually modest. The greater impact comes from reduced offensive production in wet conditions and the possibility of a shortened game. Heavy, persistent rain is more likely to influence the total than brief, scattered showers.
What wind speed affects MLB games?
Winds below 10 mph generally have minimal impact on gameplay. Moderate winds between 10 and 15 mph can begin to influence fly-ball distance depending on direction and stadium orientation. Sustained winds above 15 mph produce the most noticeable effects, particularly at open-air parks with favorable dimensions. Wrigley Field and Coors Field are the two venues where wind most frequently changes offensive expectations.
