Idaho is in for a dramatic weather ride this week, swinging from scorching summer heat to brisk, rain‑cooled relief. It’ll feel like two seasons in one—so plan accordingly.

🔥 Midweek Sizzle

Tuesday through Thursday will bring intense sun and temperatures in the low to mid-90s°F. With hot afternoons ahead, there’s a heightened risk of dehydration and heat-related fatigue, especially during outdoor work or hikes. Hydration reminders and sun protection are a must.

🌬️ Sudden Turn to Cool

Come Friday, temperatures drop sharply by up to 15°F thanks to an incoming cool front. Expect sunshine with a breeze and highs in the upper 70s. The sudden chill might surprise anyone used to the summer heat.

🌧️ Weekend Showers

An unsettled air mass moves in over the weekend. Saturday may bring a passing shower or two, with daytime highs falling to the mid‑60s—ideal for layering. Expect a return to pleasant sun and moderate warmth by early next week.

Forecasters noted that Heat Advisories are in effect midweek, followed by a sharp cooldown as air mass transitions—common but notable for early summer in Idaho.
