May showers make up for generally dry spring in Boise; highs near 90 this weekend

It hasn’t exactly been a deluge but May has been wetter than normal in Boise — 16 days with at least a trace of rain, according to National Weather Service data.

So far, 1.42 inches of precipitation have been recorded at the Boise Airport, about a quarter-inch more than normal for May.

More rain may be on the way. There’s a 20 percent chance of rain Tuesday afternoon and a 30 percent chance on Wednesday, forecasters say.

Highs Tuesday and Wednesday will be in the mid-70s, and it will gradually warm up through the weekend. Highs Saturday and Sunday should be close to 90, about 15 degrees above normal.

A system from the Pacific is expected to cool things off next week.

Both March and April were drier than normal in Boise. A little more than an inch fell in those two months, an inch and a half below normal.

Boise is still about an inch above normal on the water year (10.62 inches since Oct. 1).
