High pressure is bringing above-average heat to Idaho, with temperatures expected to reach the 70s from Friday through Monday.
Dry, sunny conditions are forecast for the weekend. Patchy frost may occur before sunshine returns and temperatures rise.
A low-pressure system from the Gulf of Alaska is expected to bring cooler air and precipitation by late in the week. Another low-pressure system is expected to move into the region early next week.
The forecast pattern follows recent changes that included storms and rain in southern Idaho before cooler, fall-like temperatures settled in.
