Cloudy & cool, scattered showers and high elevation snow continue tomorrow

The daily forecast from Idaho's largest, most experienced team of meteorologists.

BOISE, Idaho — Today was probably the first day you got to break out your full fall wardrobe, with showers and cool temperatures all around. A narrow ribbon of moisture that moved slowly from east to west led to some differing rain totals. McCall had the highest rain total of the area at .36" of rain, Boise and Mountain Home got .20" and .18", respectively. Magic Valley spots officially recorded no rain for today.

Today's rain brings Boise's monthly rain total to 0.42", just shy of the 0.43" average.

The consistent cloud cover insulated our morning temperatures, making them warmer than previous days this week. The clouds also didn't allow for too much day time heating so temperatures were about 15 degrees below average. Boise's high was 60° today.

Expect showers to continue more consistently overnight, then become more scattered in the afternoon on Sunday.

A cut off low pressure system is centered over Nevada tonight, it will slowly meander east and north through the weekend and into early next week. Isolated t-storms are also possible for some mountain spots. Snow levels will remain fairly high during this time, between 8000-9000 feet. 

On Sunday, temperatures will stay unseasonably cool for the first of October. Highs will stay in the mid to upper 50's in the Treasure Valley, but drop to the 40's/50's in the mountains with snow showers above 8000'.  The chance of showers is about 60% for the Treasure Valley, but there is a higher risk of rain/t-storms for the Magic Valley, near 80%, as well as for showers in the central mountains.

Gradually drier conditions are expected by Tuesday through the middle of next week, with slightly milder temperatures into the mid-upper 60's early in the week in Boise, and into the low 70's by midweek with mostly sunny skies.

The 2022-2023 water year ends today.  The water year total now stands at 14.71" at Boise, which is just a bit over 3" above the water year average.
