The closed upper-level low stalled over the Southwest will provide
the support for continuing precipitation chances through the
weekend, with snowfall for higher elevation terrain/mountain
ranges, and a mix of rain and snow for lower elevations. The
threat for heavy snow will focus over the Four Corners region into
Sunday, and heavy snow may redevelop over the southern Rockies on
Sunday. Probabilities are moderate to high (50-60%) for an
additional 8 inches or more of snow in the highest elevations in
southern Colorado and northern New Mexico over the weekend. Heavy
snowfall rates up to 2"/hr and gusty winds will bring some blowing
snow and reduced visibility, particularly for mountain passes,
leading to difficult to impossible travel conditions at times. The
snow is expected to taper off by Sunday for Utah and Arizona, but
linger into Monday over portions of southern Colorado and northern
New Mexico.

The next Storm Summary will be issued by the Weather Prediction
Center at 900 AM MDT. Please refer to your local National Weather
Service office for additional information on this event.
