Muggy start in Princeton

That moisture will matter as temperatures climb. Today is expected to stay sunny, with a high near 99F. Heat index values may reach as high as 102F. The chance of precipitation is 1%, so rain is not a meaningful part of the local forecast today. South wind is expected around 10 mph.
