Boise and other parts of southwest Idaho are currently experiencing intense heat, with temperatures touching 96°F on Sunday. The National Weather Service has issued a weather alert as the heatwave continues, posing a risk for heat-related issues. Residents are advised to stay safe and keep an eye on the changing weather, with some relief expected by Tuesday or Wednesday in the form of rain and thunderstorms.
Triple-Digit Heat Grips Boise and Nearby Cities
Boise, along with places like Meridian, Nampa, and Caldwell, will see temperatures reach or cross the 100°F mark. The heat has been building up over the past few days, and night-time temperatures are staying high too, hovering around 68–69°F. This means there’s very little cooling even at night.
Safety Tips for Dealing with the Heat:
Drink plenty of water throughout the day
Avoid going out during peak sun hours (12 PM to 5 PM)
Wear loose, light-coloured clothing
Take frequent breaks if working outdoors
Never leave children or pets in parked vehicles
Smoke May Reduce Visibility on Interstate 84
Along with the heat, patchy wildfire smoke is causing hazy skies, especially in Ada and Canyon counties. This is expected to impact visibility along stretches of Interstate 84, particularly on Sunday morning. If you’re driving, switch on your headlights and maintain a safe speed.
Rain and Thunderstorms Expected by Midweek
There’s good news ahead. Starting late Monday or Tuesday, a shift in the weather pattern is likely. Boise has a 30% chance of rain and thunderstorms on Tuesday afternoon, with showers possibly continuing into Wednesday and Thursday. This change could help bring down the temperatures and improve air quality.
However, the incoming showers could also lead to slick roads and short periods of heavy rain, especially in the evenings. Make sure to stay updated with the latest forecasts and plan your travel accordingly.
