...Winter Driving Conditions At Pass Level This Morning...

Snow levels have largely dropped to around 6,000ft across
Southwest Montana this morning, with further reduction in snow
levels in the heaviest precipitation east of I-15 and south of
I-90. Those traveling near pass level in these areas should be
prepared for winter driving conditions this morning, largely in
the form of reduced visibility and slushy roads. Precipitation
