Some counties in southwest Montana could potentially be impassable through Wednesday evening. Not everybody is forecasted to get crazy weather, but up to a foot or more of snow might fall in some mountain ranges. Very strong winds are supposed to be widespread - gusts of 40+ MPH will be common and 70 MPH possible.
Spring is a challenging time for us folks who like to garden in Gallatin County. I'm no expert or degree holder in horticulture but I DO feel your pain.
