Forecast
An exiting area of low pressure will be the focus for a few showers and thunderstorms on Friday. Most of the heaviest precipitation will impact areas north of I-90 to end the week. Recent precipitation has helped to moderate fire behavior and limit smoke production on many regional wildfires. Much of southwest Montana and central Idaho picked up at least a half an inch of rain between Thursday and early Friday. A light westerly flow will send some smoke into communities on the east sides of Montana wildfires.
Warmer air and lower relative humidities should lead to more active wildfire behavior across the state by this weekend. High pressure will build across the area, bringing an end to the cool and showery weather pattern. Afternoon highs will approach 90 degrees over most valleys by Sunday.
The warmer and drier weather pattern is expected to persist over the Northern Rockies into next week. Montana will be on the eastern fringes of a strong ridge of high pressure parked over the Pacific Northwest. This will keep temperatures 10-15 degrees warmer than normal. A weak Canadian cool front arrives between Tuesday and Wednesday. It will be accompanied by some surface smoke from Canadian wildfires. Stay tuned!
Conditions can change quickly as weather could stimulate active fires and the likelihood of new starts increases. Please keep track of concentrations at todaysair.mtdeq.us or the Fire and Smoke Map.
Friday morning’s satellite image shows clouds along and ahead of a departing area of low pressure. Some smoke is visible over the western edges of the state.
