Potential hazards around Helena tonight and tomorrow morning.

Wintry weather is expected for most of southwest Montana today and tomorrow as a major spring storm blasts through the state. Winter weather alerts are in place for much of the higher terrain.

We will start to see an increase in the rain rates across western Montana this afternoon, with the possibility of a few lighting strikes. Heavy snow starts tonight for a lot of the mountain ranges. Snow levels will drop below 5000 feet early tomorrow morning.

Temperatures will be in the 50s today with clouds and precipitation blanketing the state.

Snow totals through Thursday.

The remaining heavy precipitation should move out of the Capital region by noon. Scattered thunderstorms will develop in the remaining instability along the Rocky Mountain Front and travel southeastward towards Helena in the afternoon.

Tomorrow will be the coldest day, with most locations struggling to eclipse 50°.

Another low pressure system makes its way towards the state on Saturday. However, this one does not appear to be as cold and snowy as our current situation. Rain seems likely for lower elevations Saturday night into Sunday morning.
