A broad upper level trough of low pressure will remain over western Montana through Saturday. Scattered showers are expected today in the form valley rain and mountain snow. A colder air mass will move in tonight and Saturday, snow levels will drop to many valley floors, and some of the passes may see a few inches of slushy snow. The trough begins to move out on Sunday, with only a few lingering showers. Below normal temperatures will continue, with highs in the 50s Friday, falling to the 40s and low 50s on Saturday.
A ridge of high pressure will FINALLY bring us more typical spring weather early next week with some sunshine by Tuesday. Highs warm into the 60s Monday and the 70s by Wednesday.
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.
