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 hanging aroud the 50° mark.

Heavy snow expected in the mountains, but snow levels could lower enough overnight to reach the Downtown Helena area.

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.

Temperatures will warm into the 60s this weekend and we will be dry by Sunday afternoon.

Memorial day will be dry, sunny, and warm. Temperatures will reach the 70s.

Most of next week will be very warm. Temperatures will reach the 80s by the middle of the week.
