Weather Forecast: Strengthening Valley Inversions in Western Montana

Montana’s current temperatures range from single digits to lower 30s, with calm winds in the west but gusts in the east. High pressure will strengthen inversions, leading to increased fog in western valleys. A winter weather advisory is active, with an arctic outbreak expected next week.

Current temperatures in Montana vary widely, with readings in the single digits in west-central and southwest regions and the 20s to lower 30s elsewhere. Winds remain calm in western areas but experience gusts up to 30 mph in central and eastern parts. Wind chill factors have driven temperatures down to single digits in south-central Montana, though skies remain mostly clear to partly cloudy.

The weather forecast indicates that high pressure will significantly influence Montana’s climate through Thursday, leading to more pronounced inversions within western valleys. This shift will likely result in increased fog and air stagnation affecting the Missoula, Mission, Bitterroot, and Flathead Valleys. While some regions will experience milder conditions, winter weather advisories are in effect for areas like Big Timber and I-90 due to anticipated blowing and drifting snow.

A notable change is on the horizon with forecasts predicting an arctic outbreak accompanied by snowfall early next week, specifically next Sunday. Tonight, lows are expected to plunge below zero in Missoula, while other regions may experience single digits to the lower 20s. Tomorrow’s highs are projected to remain in the 20s for western valleys, with temperatures in other areas rising to the 30s and approximately 40 degrees.

This article discusses the current weather conditions in Montana and elaborates on high-pressure systems leading to valley inversions. It highlights the impact of these inversions on fog and air quality, particularly in western valleys. The article also notes the varying temperatures across the region and warns of an impending arctic outbreak that could significantly alter current weather patterns.

In summary, Montana is experiencing a period of temperature variation influenced by high pressure, resulting in increased valley inversions. While western valleys face fog and air stagnation, milder weather is expected elsewhere. Future forecasts predict drastic temperature drops and snowfall, signaling a significant weather shift in the coming week.
