The clouds have cleared for the western half of Montana, as low pressure has moved east. Montana's eastern plains will have more rainfall today, but things will clear out by tomorrow, after the low-pressure system finally moves out of the state. A high-pressure ridge will continue to move east into Montana, resulting in generally drier, warmer weather through the end of the weekend. However, a small disturbance in otherwise stable flow moving through on Friday evening will bring a slight chance of thunderstorms to north-central Montana. This disturbance will move through fairly quickly, so any thunderstorms that do develop will be short-lived.
This weekend, temperatures will warm up again. Saturday's highs will be in the mid-70s, while Sunday's temperatures will be at or near the 80-degree mark. It could be one of the warmest weekends left this year!
