Weekend Snowstorm:

Storm timing is a bit delayed compared to yesterday's data. Some snow will start late tonight, most will accumulate from Saturday afternoon through early Monday morning. Some zones may start as rain or a mix of rain and snow, especially along the I-25 corridor (see graphic below). A transition to snow is expected by Saturday night or Sunday at the latest, for the I-25 corridor. The eastern plains will stay as rain during this event, picking up widespread 0.5" up to 1" in isolated spots.

Winds will be very strong on Sunday, with frequent gusts 30-40 mph and gusting 40-50 mph at times, which will cause blowing snow and reduced visibility.
