I believe snow started today

Snow fall in Helena MT

How much snow do you think Helena MT will get during the 2018-2019 winter. Will it be more or less than last year

Given the way this year has

Given the way this year has gone, I’d say way less than normal

Sept 5th through 7th

Planning a wedding the 2nd weekend of September in Bigfork, Montana. Sept 5-7th 2019. What will the average temperature be? and rain fall?

Mild Maybe

I hope you folks are correct (usually are:) which means I will hopefully see a relatively mild winter this year- last year was brutal here in SW Bozeman, MT... my van was froze to the pavement most of last winter (an unusually abundant amount of ice) :/ I will be looking forward to relatively better weather this year, tytyty. :D
