Today’s MLB Weather Forecast

• Highest Delay Risk: The Mets at Braves game carries the only meaningful delay concern as afternoon thunderstorms linger near first pitch.
• Expected Postponements: None expected. All storm activity is scattered and short-lived.
• Most Significant Wind: Oracle Park’s sustained WSW breeze (7-11 mph with gusts near 20 mph) pairs with cool marine air to suppress offense.
• Primary Weather Story: A broad ridge of heat dominates the central U.S. with temperatures near 95°F in St. Louis, while scattered afternoon thunderstorms across the Southeast create a narrow delay concern window for Atlanta’s evening game.

At-a-Glance Weather Table

Highest Rain Delay Risk Games Today

Mets at Braves (7:15 p.m. ET)

Delay Risk: MODERATE

Scattered afternoon thunderstorms have developed across the Atlanta metro area beginning around 3 p.m., with peak intensity near 5 p.m. (30% precipitation chance). The storm window extends through 7 p.m. (27%), placing first pitch at the tail end of the active period. By 8 p.m., chances drop sharply to 9% as storms push east of Truist Park. A brief delay near first pitch is plausible if a lingering cell passes through, though conditions should improve rapidly once the game begins. Postponement risk is negligible.

Weather Timeline

• 3:00-5:00 p.m. — Scattered thunderstorms develop west of Atlanta and move through the metro; peak intensity (28-30%).
• 5:00-7:00 p.m. — Storms weaken as they push through Truist Park area; coverage diminishing (27-29%).
• 7:15 p.m. — First pitch; tail end of storm window with 27% chance of lingering cells.
• 8:00 p.m. — Rapid clearing; precipitation drops to 9%, and conditions stabilize for the remainder of the game.

Games Expected to Play Without Weather Issues

• Orioles at Twins — Clear skies and zero precipitation risk at Target Field throughout the afternoon.
• Mariners at Yankees — Hot but dry conditions in the Bronx with precipitation chances at 2% through the entire game.
• Brewers at Padres — Typical San Diego conditions with westerly breeze and no precipitation concern.

DFS and Betting Weather Outlook

Astros at Giants

Oracle Park’s marine layer is in full effect this afternoon. Temperatures sit at 64°F with WSW winds gusting near 20 mph blowing toward left-center field. The cool, dense air significantly suppresses fly-ball carry and home-run potential. This is one of the most pitcher-friendly environments on today’s slate, making it an ideal spot to fade power-heavy stacks and target under-focused approaches on run totals.

Phillies at Cardinals

Extreme heat at Busch Stadium creates the highest-temperature environment on Wednesday’s slate. First-pitch temperatures near 94°F rise above 95°F during the middle innings, with heat index values exceeding 105°F. The warm, dry air modestly enhances ball carry. The more meaningful DFS consideration is a slight chance of thunderstorms (18-26%) developing between the 4th and 7th innings, which could interrupt play and disrupt starting pitchers’ workloads. Monitor radar as the game progresses.

Mets at Braves

Delay uncertainty at Truist Park introduces roster-construction risk for DFS lineups locking near 7 p.m. If storms linger past first pitch, starting pitchers could face disrupted warm-up routines or shortened outings. The value play here is waiting for the 7 p.m. radar update before committing to Braves or Mets stacks. If storms clear before 7:15 p.m., the warm conditions (87°F) with moderate humidity create a neutral-to-slightly favorable hitting environment.

FAQs

Which MLB games face the highest rain delay risk today?

The Mets at Braves game (7:15 p.m. ET) carries the only meaningful delay concern on Wednesday’s slate. Scattered thunderstorms are expected to linger near Truist Park through first pitch, with a 27% chance of precipitation at 7 p.m., dropping to 9% by 8 p.m. All other games carry precipitation chances below 15% and are expected to start on time without interruption.

Should I fade starting pitchers in rain-delay games?

Rain delays longer than 30 minutes frequently lead to early pitcher exits regardless of pitch count. Managers protect arms rather than push starters through disrupted outings, which means you’re often paying for 4-5 innings instead of the 6+ you projected. In DFS, this compresses the ceiling on pitcher scoring and shifts value toward bullpen-heavy game stacks. For today’s slate, this applies most directly to the Mets at Braves game where a first-pitch delay could shorten both starters’ outings.

How do rain delays affect live betting odds?

Sportsbooks typically suspend live markets during active delays and reopen with adjusted lines once play resumes. The key shift happens on run totals — a shortened game with fresh bullpen arms often moves the live total down, while a delay that pulls a dominant starter creates value on the over. Pre-game, books rarely adjust lines for forecasted delay risk below 40%, so the edge for bettors comes from monitoring radar closer to first pitch than the market does.

How late can I swap a DFS lineup if a game gets delayed?

On DraftKings, lineups lock at the scheduled first pitch of the earliest game in your contest, not when the delayed game actually starts. If a delay is announced after lock, you cannot adjust. This is why radar monitoring 30-60 minutes before lock matters more than the morning forecast. For single-game contests, lineups lock at that specific game’s scheduled start time — a pre-pitch delay announcement gives you no additional swap window unless the platform explicitly extends lock.
