At this year's marathon, finishing early might save you a soaking.
Race-day is expected to begin with temperatures in the mid-40s and a 35 percent chance of rain at the marathon's start time of 7 a.m., according to National Weather Service meteorologist Rihaan Gangat. The likelihood of rain increases steadily throughout the morning to about 50 percent by 2 p.m., he said.
But wait, there's still good news.
"It should be scattered," said Mr. Gangat, at the weather service's offices in Moon. "No thunderstorms."
The temperature should reach the mid-60s by 2 p.m., he said.
Runners and walkers who need to cool off during the race will have some additional help beyond a paper cup of water: refreshing breezes scooting along behind the rain.
Wind gusts are expected to reach 10 miles per hour by start time, rising to about 15 mph by early afternoon, Mr. Gangat said.
"It could be a little gusty with the showers, but it shouldn't be terribly windy," he said.
