The week leading into Memorial Day Holiday Weekend will be very active with numerous thunderstorms and significant rain. Thunderstorms will move through the state every day, and heavy downpours are likely with the storms. Also, this stormy weather will spread cooler temperatures and a lot of rain across western Canada and the wildfires that have caused smoky conditions. The wildfire activity will likely be doused with rain helping firefighters get the upper hand. More good news, the smoke has moved out of Montana and most of the state is looking at "good" air quality. With rain on the Canadian fires, it's unlikely we have another round of smoke and poor air quality. Tuesday will start out partly to mostly sunny but scattered thunderstorms will develop through the afternoon and evening. Highs will be in the 60s and 70s. Another wave of thunderstorms will hit the state hard on Wednesday, especially across central and western areas. Highs will be a little cooler in the 60s to around 70 with more moisture and cloud cover. Thursday will be mostly cloudy with widespread rain and thunderstorms. Highs will be a few degrees cooler than average with most of the state in the 60s to near 70. Friday is a big travel day and there will be big thunderstorms through the afternoon and evening. Highs will be close to average in the 60s and low 70s. Memorial Day Weekend is looking decent, but there will be thunderstorms around with the possibility of washing out outdoor activities. Saturday will have a mix of clouds and sun with scattered showers and thunderstorms through the afternoon. If you're planning on being outside, plan on having wet weather in the afternoon and evening. Highs will be in the 60s and 70s, but thunderstorms can cool temperatures down quickly especially in the mountains. Sunday will be partly cloudy to start but widespread thunderstorms are likely through the afternoon and evening. Monday will be mostly sunny with just a few isolated thunderstorms as a front moves through the state. Highs will be in the 70s and Memorial Day should be the driest day, although central and southern areas will have some isolate storms. Although on the typically unsettled side, at least Memorial Day Weekend does not appear to have any snow.
