September 18, 2013 

— It may be four more days until the official start of autumn, but the feel of fall has already settled in Boise.

Highs Wednesday will reach only 65 degrees, according to the National Weather Service. Overnight Wednesday, temperatures will fall as low as 43 degrees.

Thursday will be a little warmer, with clear skies and a high of 73 degrees. Temperatures will rise to 83 degrees Friday.

But the warm weather will flee again by Saturday, the last official day of summer. A 30 percent chance of rain is in effect, with thunderstorms possible after 1 p.m. and highs hovering in the low 70s.

Sunday will be clear and cool, with a high of 67 degrees and a low of 43 degrees.
