Boise, ID – A round of light rain will sweep across Boise and the Treasure Valley early this week, with a sunny stretch expected to return by Thursday. The incoming weather system will bring patchy fog, cooler mornings, and some damp commutes, but conditions are set to improve as the week progresses.
Light Showers to Start the Week
According to the National Weather Service in Boise, scattered showers will begin Tuesday morning and last through Wednesday. The best chances for rainfall are expected between late morning and early afternoon each day. While rainfall totals are forecasted to remain light, drivers should be aware of reduced visibility, especially on highways like I-84 and U.S. 20 during the morning commute, as low clouds and fog may briefly lower visibility.
The showers on Tuesday will be light and intermittent, meaning they won’t bring significant accumulation. However, the cooler temperatures combined with foggy conditions in the early mornings may make for damp and slippery roads, so drivers are urged to use caution during the morning commute hours.
Clearing Skies and Dry Conditions by Wednesday Night
By Wednesday evening, the showers will begin to fade, and skies are expected to clear. As drier air moves in over southwestern Idaho, temperatures will rebound quickly, reaching the low 60s by Thursday. The transition from rain to clear skies will set the stage for a pleasant Thursday afternoon with mostly sunny conditions.
While daytime temperatures will climb back into the 60s, residents can expect cooler mornings throughout the week, especially by Friday, with temperatures dipping into the upper 30s at night. The cool mornings could bring areas of patchy valley fog, particularly along the Boise River and near Caldwell, so early risers should be prepared for reduced visibility in certain areas.
Fall Weather Perfect for Outdoor Activities
As the weather clears, outdoor events, harvest work, and fall yard preparation should benefit from the return of dry and stable conditions. With mostly sunny skies expected by Thursday and continuing through Friday and the weekend, it’s an ideal time to enjoy fall activities.
The weather is expected to remain calm and mild through the weekend, with sunny skies and temperatures reaching mid-60s on Friday and low 60s on Saturday. The ideal fall weather will continue, with residents enjoying mild temperatures and comfortable outdoor conditions.
A Weak System on the Horizon for Next Week
Looking ahead, the forecast suggests that a weak weather system may approach early next week. However, no significant rain or wind impacts are anticipated at this time. It’s expected to be another calm and dry week, following the drier conditions that will dominate later this week.
