The cool and damp early May weather will continue. A wave of moisture will move out of the area this evening, with a lingering rain, snow or graupel shower, then partly cloudy and cold. Lows in the 20s to lower 30s. Another wave of Pacific moisture will move into the region tomorrow, bringing a chance of mainly afternoon showers. A stronger storm system will then move into western Montana Friday through the weekend. It will bring a good chance of rain or a mix on Friday, with rain and snow possible both Saturday and Sunday.

Temperatures will remain below normal with highs in the upper 40s and 50s through the weekend. A warming trend and drier weather is expected early next week when highs may finally get back to the normal 60s.

The moon will officially become full Saturday (May 5), and because this month's full moon coincides with the moon's perigee - its closest approach to Earth - it will also be the year's biggest.
