BOZEMAN – Spring-like weather is on hold for most of this week. Temperatures will continue to be colder than normal and another storm system will drop through the state from Canada Tuesday night through Thursday morning.

The last storm system produced widespread snow Saturday night into Sunday and with snow on the ground combined with mostly clear skies temperatures fell close to record cold levels Monday mornings. Dillon bottomed out at 7 degrees Monday morning shattering their old record low of 12 in 1986. Livingston started the day at 4 this morning and that shattered the old record low of 6 set in 1903. West Yellowstone fell below zero this morning but stayed 1 degree above record pace with -9 for a low and a record of -10 in 1933.

The next weather maker will bring another round of widespread snow to Montana beginning Tuesday afternoon through Thursday morning. This will be similar to the last storm system on Saturday as a cold front drops into Montana from Canada.

Valley and mountain snow is likely with most mountain ranges picking up around 5”-10” at pass level land possibly over a foot for higher peaks. Valleys could see 2”-6” of snow. This is a very early estimate on possible snow totals and will likely change slightly in the next 24 hours with updated model runs.

The National Weather Service issued a WINTER WEATHER ADVISORY for SW Montana east of the divide from 9 pm Tuesday to 3 pm Wednesday.

Snow accumulations: Valley 2"-5", Mountain 5"-10".

Wind gusts 30+ MPH could produce areas of blowing snow and lower visibility.
