Most locations stay dry during the day, but isolated showers and thunderstorms will develop near the Nevada border late this afternoon and evening. Any storms that form could produce strong and erratic outflow winds, even in areas that don't receive much rainfall.

Chance of rain Saturday

Storm chances increase tonight as a weather system moves north through the Great Basin. Scattered showers and a few thunderstorms will spread into southern Idaho overnight and continue into Saturday.

A Red Flag Warning is in effect from Friday afternoon through Saturday morning for the Western Magic Valley and southeast Oregon. A Fire Weather Watch has also been issued for portions of the Eastern Magic Valley.

With hot, dry, and windy conditions in place, avoid outdoor burning and use caution with anything that could create a spark. If a fire starts, it could spread quickly and become difficult to control. Stay weather aware and report any signs of smoke or fire immediately.

Watches/warnings

Saturday looks to be the most active day of the weekend. Scattered showers and thunderstorms are expected across southwest Idaho and eastern Oregon, with some storms capable of producing gusty winds, brief heavy rain, and small hail during the afternoon and evening. Not everyone will see rain, but those with outdoor plans should stay weather aware.

The cloud cover and rain chances will help knock temperatures down a bit this weekend, with highs settling closer to 5 degrees above normal Saturday and Sunday.

The subtle cool down won't last long. High pressure rebuilds early next week, sending temperatures back into the upper 90s and potentially near 100 degrees by Tuesday and Wednesday.
