More snow will fall over the next few days before even worse weather hits this weekend.  The snow is deep, and the snowbanks are getting huge.  This coming after between 1-3 FEET of snow has fallen over much of central and southern Montana since the weekend.  Two more snow events will hit before high pressure pushes the snow out.  However it’s an arctic high pressure that will likely produce record cold this weekend.

Thursday will have areas of snow moving across the state accumulating 1-4″ in the lower elevations.  Highs will warm into the 10s and 20s.  Friday will get even nastier as an arctic front moves south through the state.  Snow will fly, but wind will increase.  Wind chills will become dangerously cold.  The wind will also blow the snow around reducing visibility.  Temperatures will fall below 0 by Friday evening.  Some snow will continue into Saturday, but at this point the temperature and wind chill will become the dominant weather features.  Highs on Saturday will likely be below 0, with wind chills as cold as -30 to -40.  Arctic high pressure will settle over the state Saturday night with clearing skies and calm wind.  This will allow temperatures to plummet to between -20 and -40 by Sunday morning.  Sunday will be sunny but very cold, with highs only in the -0s to 0s.  Sunday night will also be extremely cold, with lows once again between -20 and -40.  Temperatures will modify some next week as the arctic air loosens its grip on Big Sky.  Not to say there isn’t more snow or very cold temperatures in the forecast, but the weather pattern will return closer to normal for early March.

Stay safe and warm.
