MISSOULA — Snow stays isolated this weekend, but there is a chance we still see a few flurries and rain drops.

Temperatures stay very warm, and highs top out in the upper 30s and low 40s.

With a lot of extra snow on the ground at all elevations, we can expect melting of snow with these warmer temperatures.

Melting will create excess runoff, and pooling water is possible on roadways and farmland.

These puddles that collect on roadways will refreeze overnight (especially in upper elevations), and there will be a few icy spots on roadways.

Another widespread push of moisture arrives Sunday night/early Monday morning.

As we keep warmer weather around during this time, we can expect snow levels to fluctuate between around 5,500’ to valley floors.

This will continue to lead to melting, pooling of water, and refreezing at night.
