BOZEMAN – Cooler than normal temperatures will continue into the first half of the Memorial Day Weekend for SW Montana. Temperatures will only reach the 50s Saturday but could warm up into the upper 60s to low 70s by Monday.

The next wet weather maker is lifting up into SW Montana from Idaho. A strong SW flow aloft is paving the way for increasing rain and snow to impact SW Montana mostly east of the divide. Areas of greatest concern will be Beaverhead, Madison, Gallatin, and Park counties.

Areas of moderate to heavy rain are possible from Livingston to Billings to Red Lodge.
