The warmest weather of the year and the warmest weather since the middle of September will move in this weekend. The first 80 degree temperatures are likely to move through much of western and central Montana by Mother’s Day. However, before the weekend warmth will be one more stormy day with showers, thunderstorms and even some snow. A ridge of high pressure is currently positioned off the Pacific coast, which leaves Montana in a northwest flow. A disturbance from Canada moved through on Tuesday kicking off the showers and thunderstorms. Another wave of low pressure will come down from Canada for Wednesday with more showers, thunderstorms, mountain snow and slightly cooler temperatures. Most of the wet weather will be in the western and central parts of the state. With cooler temperatures, snow may mix down to around 5000′ at times in the evening. Thunderstorms could produce small hail and brief heavy downpours. As the storm clears out Wednesday night, overnight lows will dip into the 20s to around 30 for most of Montana. Thursday will be sunny and warmer with highs in the 50s and 60s. This is when the really nice weather begins. Friday will be mostly sunny and warmer, with highs in the 60s to around 70. This weekend will be sunny and warm with Saturday’s highs in the 60s and 70s. Sunday will likely be the warmest day since September 10th as highs hit the 70s and low 80s. Temperatures will cool slightly with thunderstorms moving back in for the beginning of next week.
Have a great day.
