Maybe they should have kept the games in Marlin's Park. San Francisco is expecting rain in their forecast as the 2013 World Baseball Classic championship is set to be played in AT&T Park. After studying the radar, the trajectory of a system with clouds and rain looks headed right towards San Francisco. Let's break this down.
Currently, it's 12 p.m. in San Francisco. There are some showers off the shore of norther California. At around 3:30 p.m. PT, showers are developing around Sunnyvale, which ironically won't be seeing much sun rays according to the report. By 4 p.m., the rain begins to spread north, just two hours before game time it looks to be headed towards San Francisco.
As for the hour-by-hour break down, this is what Weather.com shows. Currently, the humidity is fluctuating between 50-60 percent. From 7 p.m. PT until 9 p.m. PT, the humidity will slowly increase into the 80's, which will therefore increase the chances of rain.
Now, we know the weather loves to play games. If it said 100 percent humidity, then it would mean the chances of rain are definite, however, the 80 percent peak of humidity does not guarantee that they'll be a downpour tonight during the game.
The grounds crew should be air of the possible incoming showers, but for the fans, take an umbrella or a pancho just to make sure you remain dry as the action is going on. The last thing you'd want to do is purchase something at the park. Buying food in some of these baseball parks seems like an investment already.
As far as the temperature, it will remain in the mid to lower 60's, peaking at 64 degrees at 2 p.m. PT. Half way through the game, it should deep into the upper 50's where it will remain for the remainder of the night. There will be a slight breeze blowing at around five to seven miles per hour. It should be heavier at around first pitch.
All in all, aside from the possible showers, the temperature should be perfect for baseball as the Dominican Republic and Puerto Rico face off.
It will be a historic night as neither country has ever won the WBC tournament in the past. For the Dominicans, it could possibly be a greater victory since they would remain undefeated and become the first team to do so in the tournament. Win or lose they will possess the best winning percentage in a single tournament bettering the Japaneses' 2009 effort when they finished 7-2.
