Boise, ID – A significant change in the weather pattern is approaching southwest Idaho, with widespread rain, mountain snow and falling temperatures expected between Sunday, Nov. 15, and Tuesday, Nov. 17. Forecasters indicate precipitation chances could reach 80% in Boise and 100% in McCall as another Pacific storm moves inland.
According to the National Weather Service in Boise, drier conditions will continue Saturday and through much of Sunday before a Pacific low pressure system brings renewed precipitation and cooler temperatures early next week.
Boise is forecast to reach 68 degrees Saturday before afternoon highs drop to 60 Sunday, 51 Monday and 48 Tuesday.
Rain chances in Boise increase to 45% around midnight Monday, climbing to 80% by 6 a.m. before decreasing later in the day.

Mountain communities could experience more wintry conditions.
McCall's precipitation probability rises to 90% Sunday evening, 95% early Monday and 100% by Monday morning, with the forecast indicating a mixture of precipitation types during portions of the storm.

Burns is forecast to reach 100% precipitation probability Sunday afternoon, followed by colder conditions and a Tuesday morning low near 13 degrees.
The combination of falling temperatures and changing precipitation types could create slick conditions in higher elevations, particularly along mountain routes.
