After a partly cloudy, breezy and seasonable Wednesday, we can expect more of the same on Thursday as an upper-level low begins to slide east, pushing a front into the region. That front will stall for a time, setting up a narrow band of heavier rain. The corridor most favored stretches from near the Oregon–Idaho–Nevada border up through Mountain Home into the Boise Mountains along with parts of the central mountains south and east of McCall.
In this zone, some spots could pick up 1"-1.5" of rain, while others just outside the band see much less — a small shift in the front’s position could make a big difference- this is what we will continue to watch for.
The Boise area could experience heavier rain after midnight on Thursday night into early Friday morning, followed by showers tapering off before midday, and breezy afternoon conditions with chilly temperatures.
Friday brings the low farther east, with showers tapering off from west to east. Behind the front, cooler air settles in with highs only in the mid-60s in the valleys and mid-50s in the mountains — about 5 to 10 degrees below average. Gusty northwest winds kick in Friday into Saturday, especially along the I-84 corridor, where 25–35 mph gusts are possible.
Sunday stays cool, but the breeze will settle down. As we head into early next week, conditions trend drier with a gradual warm-up back toward seasonal norms.
