Highest Rain Delay Risk Games Today
Yankees at Cubs (2:20 p.m. ET)
Delay Risk: HIGH
Showers become likely around 5 p.m. CT (the fourth or fifth inning of this afternoon start), with thunderstorms expected to follow during the evening hours. The NWS forecasts a 100% chance of precipitation tonight, with half to three-quarters of an inch of rain and gusts up to 25 mph. The pre-game window looks playable, but the forecast deteriorates quickly once storms arrive. A mid-game delay appears probable, and a multi-hour interruption is realistic if thunderstorms reach Wrigley Field during the later innings. Wrigley’s open-air exposure and the timing of this system make this the most vulnerable game on the slate.
Royals at Rockies (8:40 p.m. ET)
Delay Risk: MODERATE
Thunderstorms are possible before 10 p.m. MT at Coors Field, with a 40% chance of precipitation during the game window. Denver’s typical summer storm pattern often produces brief but intense cells that can interrupt play. The storms are expected to taper after 10 p.m., meaning a delayed start or short mid-game interruption is plausible rather than a prolonged delay. Forecast confidence is moderate given the scattered nature of Colorado’s summer convection.
Games Expected to Play Without Weather Issues
- Phillies at Orioles — Clear and calm with partly cloudy skies and no precipitation threat.
- Marlins at Mets — Dry evening with light southerly winds and partly cloudy conditions.
- Pirates at Reds — Warm and humid but no rain in the forecast through the evening hours.
DFS & Betting Weather Outlook
Yankees at Cubs
Delay uncertainty creates meaningful risk for DFS lineups and starting pitcher exposure. If storms arrive during the middle innings, shortened outings become likely regardless of performance. The south-southeast wind blowing toward the outfield at Wrigley could enhance fly-ball carry before the storms hit, creating a volatile offensive environment early. Bettors should monitor the radar closely; a delayed start could alter bullpen usage and affect total runs.
Royals at Rockies
Coors Field’s elevation already inflates offense, and warm temperatures in the upper 70s maintain that effect. The thunderstorm risk introduces slight uncertainty around game completion timing, but the primary DFS story remains the elevation-driven offensive environment. Light northeast winds should not meaningfully suppress or enhance carry beyond Coors Field’s natural tendencies.
