High Pressure Set to Bring Fog and Cold Temperatures to Inland Northwest

High pressure is returning to the Inland Northwest, bringing fog and consistently cold temperatures, with daytime highs in the low 30s and overnight lows in the upper 20s. Sporadic low-elevation snow showers are anticipated by week’s end.

The Inland Northwest is poised to experience a return of high-pressure weather conditions, leading to the development of fog and persistently cold temperatures for the foreseeable future. The departure of weekend showers ushers in a stable ridge beginning Monday and continuing into Tuesday, characterized by an inversion that facilitates morning fog and minimal temperature fluctuations between night and day, with daytime highs remaining in the low 30s and overnight lows hovering near the upper 20s. By the end of the week, there is an expectation of sporadic showers, notably low-elevation snow, adding to the winter conditions.

Understanding the weather patterns in the Inland Northwest is crucial, particularly how high-pressure systems influence local climates. The high-pressure ridge acts as a barrier, leading to inversions where colder air becomes trapped under warmer air, resulting in fog formation and stabilizing temperatures. This phenomenon can dramatically affect visibility and road conditions during the morning hours.

In summary, the Inland Northwest is set to experience a period dominated by high pressure, resulting in cold temperatures and foggy conditions. The upcoming days will feature minimal temperature variability, with a slight chance of adverse weather toward the week’s end, illustrating the changing dynamics of winter weather in the region.
