BOISE, Idaho —
A beautiful stretch of weather is ahead for much of Idaho. However, there are still some chances of mountain showers throughout the weekend. This activity is fueled by a low pressure system that is centered in southeastern Idaho. It's bringing moisture back into the central mountain area this afternoon and evening. We look to see a similar pattern tomorrow, but with less moisture. Today and tomorrow expect to see mainly showery activity with some isolated stronger thunderstorms in these areas; mainly in the afternoon and evening hours.
Mostly sunny skies for many Treasure Valley locations today. Morning lows dipped to the mid to upper 40's, close to normal for the end of September, and afternoon highs reached the low 70's, with breezy northwest winds.
Saturday looks to be very similar to Friday for valley locations; the main difference on Saturday will be the decreasing winds.
Heading into the weekend and the month of October, look for mostly sunny days and clear nights through next week. Morning lows will be cool in the upper 40's to low 50's in the Treasure Valley, with afternoon highs in the low to mid 70's on Saturday in Boise, the mid to upper 70's on Sunday, and near 80 degrees through next week.
By the way, September in Boise turned out to be the warmest on record, with an average temperature of 71.6°, which is a full 5.1° above average. But it was a drier-than-average month, with only 24-hundredths of an inch of rain, which is 17-hundredths of an inch below normal.
