BOISE, Idaho — Fall officially begins early Monday morning, as the autumnal equinox occurs at 1:50 A.M.  While the week will start off with sunshine and comfortable temps, the forecast looks much more fall-like toward the end of the week and into next weekend.

Clouds will thicken in this evening ahead of our next front.  This will bring a slight chance for spot showers into very early Monday morning.  Any wet weather overnight should end early on Monday morning -- before the kids head out to the bus stop.  For the rest of the day, expect mostly sunny skies, a light breeze and temps in the low 70s for the Treasure Valley.

Tuesday and Wednesday are dry and mostly sunny, with highs in the low to mid 70s.  Enjoy these pleasant afternoons!  

We'll be turning a corner late Thursday, as a large low-pressure system drops into the region.  Thursday may feature a few showers during the afternoon and evening, and this is only the beginning of the cooler fall weather to come.  Temps will gradually cool into the weekend, for highs only in the upper 50s for the valley.  Low temps for the valley may drop into the mid and upper 30s by next Sunday.

While Friday looks dry for now, Saturday runs a decent chance of scattered showers.  This may even mean some snow for our mountains, around 5,000-6,000 feet!
