AccuWeather's Ali Reid discusses how Major League ballparks track weather, prepare the field and make game-time decisions before the first pitch.

Philadelphia

Major League Baseball stadiums employ dedicated teams to monitor weather conditions and prepare the field before games begin. Using radar, weather models, and constant communication with league officials, these crews make critical decisions about whether to proceed with games, delay, or postpone them entirely.

At Citizens Bank Park in Philadelphia, a recent weather event led to the postponement of a game and the scheduling of a doubleheader. Stadium staff rely on real-time data and frequent coordination to protect players, fans, and the integrity of the game, especially during severe weather events such as storms or extreme heat.

From radar to rain delays: Weather and baseball

Before the first pitch is thrown, Major League ballparks across the country are already hard at work tracking weather, prepping the field, and making game time decisions long before the fans arrive. Our Allie Reid is live this morning from Citizens Bank Park in Philadelphia with a behind-the-scenes look at how stadium crews handle everything from heat waves to rain delays. Good morning, Allie. Good morning, guys. It feels like a perfect morning for a little baseball live from Citizens Bank Park here in Philadelphia. Yesterday, maybe not the best day. In fact, it was yesterday's weather that game time officials said, you know what, we need to cancel yesterday's game. They postponed it to today, which means the weather quite literally caused a double header leading into today. So that just goes to show you that when it comes to the forecast, MLB decisions are really led up to what happens day to day with the weather. Now, here at Citizens Bank Park across Philadelphia, and really across any MLB stadium here in the United States, grounds crews and operations teams rely heavily not only on radar, but also coordination with league officials and some fast-moving teamwork to make the call on whether to play ball or hit pause. Now, behind the scenes as game day preparations on the field begin, officials are locked into weather data, radar updates, and model forecasts, all to keep the game safe and on schedule. Now, as storms build or temperatures store, communication intensifies, right, often spanning multiple calls. Live radar reads as conditions shift hour by hour. That's exactly what happened yesterday. And for stadium staff, there's no such thing as a routine day when weather is on the move. And so far today, I've had a weather call at 1130, I've had a call with MLB at around noon, and then I have another weather call at two today. Really, I live pretty much in the moment, because as you know, weather can change all the time. So, I mean, and that's why you're calling constantly to find out what's going on. Are we still looking at, we're going to have thunderstorms rolling at six to push back a little, because as you know, I mean, we're going off models. That real-time coordination drives decisions like when to irrigate the outfield, lay down fresh dirt on the infield, or cover the mound. On rain days, tarps are rolled out in seconds to protect the playing surface, while officials assess whether a delay, postponement, or full cancellation is the safest option. Whether it's triple-digit heat or approaching lightning, stadiums rely on weather precision to protect players, fans, and of course, the game itself. Again, talk about a perfect day. You couldn't ask for a better live story when you're dealing with that postponement yesterday. Leading into today, a doubleheader here at Citizens Bank Park. All due, guys, let me emphasize the weather. And you know what, I'm sure the vending machines aren't open, or the restaurants aren't open, yeah, but if they were, I'd get a Philadelphia cheesesteak. Or some crab fries. Something like that, yeah. Some chickies and peas, maybe some Tony Luke's, yeah, you know, the usual. Food, food, food, food, food. All right, Ali. Thank you, Ali. Let's take a look at the weather for the doubleheader here. You can see first game around the one o'clock time period. We're starting to be holding on to clouds, should be clearing as we head into the second game there starting at 6.15.
