MLB Games to Monitor for Weather
Reds at Braves (7:15 p.m. ET)
Weather Risk: MODERATE
Scattered showers and thunderstorms are possible near first pitch at Truist Park. The NWS forecast shows a 24% chance of precipitation around 7:00 p.m., with the threat concentrated between 6:00 and 8:00 p.m. before conditions improve. The storms appear isolated rather than widespread, and the window of concern narrows quickly after 8:00 p.m. A brief interruption is plausible, but a postponement remains unlikely.
Weather Timeline
- 6:00-7:00 p.m. — Slight chance of showers and thunderstorms developing; 20-24% chance of precipitation
- 7:00-8:00 p.m. — Peak concern window; thunderstorm chances begin easing after first pitch
- 8:00-9:00 p.m. — Precipitation chance drops to 13-15%; conditions trend toward mostly cloudy
- 9:00 p.m. onward — Storms exit; mostly cloudy skies with minimal rain risk
Diamondbacks at Rockies (8:40 p.m. ET)
Weather Risk: MODERATE
Coors Field faces the most notable weather concern on Wednesday’s slate. Afternoon thunderstorms are forecast to develop along the Front Range by early evening, with precipitation chances reaching 49% between 6:00 and 11:00 p.m. local time. The storms are expected to transition from thunderstorms to rain showers through the evening. Light westerly winds (5-7 mph) mean the storm’s impact will primarily come from precipitation rather than wind. An interruption is possible, though the scattered nature of the storms means the game could navigate between cells.
Weather Timeline
- 5:00-6:00 p.m. MT — Thunderstorms develop west of Denver; 38% precipitation chance
- 6:00-7:00 p.m. MT — Storm coverage increases; precipitation chance reaches 49% near first pitch
- 7:00-9:00 p.m. MT — Thunderstorms transition to rain showers; 49% precipitation chance persists

DFS and Betting Weather Notes
Diamondbacks at Rockies
Coors Field’s thunderstorm potential introduces lineup uncertainty for DFS players stacking this game. The 49% precipitation chance during the game window creates risk for anyone heavily invested in this matchup. If storms arrive on schedule, interruptions could disrupt pitcher rhythm and shorten outings. Monitor radar closely before lock; if storms track south of Denver, this remains one of the slate’s highest-ceiling offensive environments given Coors Field’s elevation and warm pre-storm temperatures in the mid-70s.
Guardians at Red Sox
Fenway Park’s cool temperatures (mid-to-upper 50s) and 12-15 mph northeast winds create a modestly pitcher-friendly environment Wednesday night. The inbound wind from the northeast could suppress fly-ball carry, particularly toward the Green Monster. Pitchers with strong ground-ball tendencies benefit most. Bettors may want to note that these conditions lean slightly toward the under.
Marlins at Cubs
Wrigley Field sees 15 mph east-northeast winds and temperatures in the low 60s. Wind from the east-northeast at Wrigley generally blows across the field rather than straight in or out, limiting its direct impact on home-run carry. Combined with the cool air, conditions slightly favor pitchers. The wind and temperature together create a modest suppression effect that could keep scoring in check.
FAQs
What MLB stadiums have retractable roofs?
Six MLB stadiums have retractable roofs: Globe Life Field (Rangers), T-Mobile Park (Mariners), Daikin Park (Astros), loanDepot park (Marlins), American Family Field (Brewers), and Chase Field (Diamondbacks). Rogers Centre in Toronto also features a retractable roof. These venues can close their roofs during threatening weather or extreme temperatures, which generally eliminates weather risk for the game.
How does cold weather affect MLB games?
Cooler temperatures tend to suppress ball carry and reduce offensive production. Dense, cold air creates more resistance on batted balls, which can lower home-run rates and slightly favor pitchers. Games played in temperatures below 60°F typically see a modest decrease in run scoring compared to games played in warmer conditions. DFS players should factor temperature into their lineup construction, particularly when stacking hitters at cool-weather venues.
How do thunderstorms affect MLB betting totals?
Thunderstorms create uncertainty that can influence both pregame and live betting markets. When storms threaten, game interruptions can disrupt pitcher rhythm, alter bullpen usage, and shorten games. These variables often lead to increased volatility in total runs. Bettors should monitor radar closely before placing totals bets on games with thunderstorm potential, as conditions can change rapidly and affect whether the game completes nine full innings.
How does humidity affect home runs in baseball?
Contrary to popular belief, humid air is actually slightly less dense than dry air because water molecules are lighter than nitrogen and oxygen molecules. This means humid conditions can marginally increase ball carry and home-run distance. The effect is modest compared to factors like wind and temperature, but it becomes most noticeable at hitter-friendly parks at higher elevations. Humidity also contributes to thunderstorm development, which can introduce separate weather-risk concerns.
