Snow, cold, wind and icicles were found this past weekend as a bit of winter struck the state. Big changes are in the works as high pressure has cleared out the snow, clouds and cold replacing that with sun and warmer temperatures. The weather pattern that is developing over much of the West is called a Rex Block. This occurs when high pressure develops to the north (or above) an area of low pressure. Once established, this weather pattern can persist for days or even weeks. Montana will be under the influence of high pressure with the low pressure down below to our south. High pressure will make for generally clear skies and warmer temperatures that will last for most of this week and through the weekend. There will be a few minor changes as wind shifts will cool and warm the temperature by about 10-15 degrees on a few days. Generally, temperatures will be above average and precipitation will be well below average into next week with the Rex Block dominating the weather across the West. Enjoy this beautiful stretch of Indian Summer because it won’t last forever. Colder temperatures and snow loom toward the end of the month and the start of November.
