winter storm shifts southwestward over the Four Corners Region...

Winter Storm Warnings are in effect for higher elevation/mountain
range regions of southern Utah, southern Colorado, and northern
New Mexico.

elevation/mountain range regions of southern Utah, southern
Colorado, northern and central New Mexico and Arizona.

For a detailed graphical depiction of the latest watches, warnings
and advisories, please see www.weather.gov

At 1000 PM EDT...A slow moving cold front has moved southward
through the Four Corners region to near the Mexican border,
bringing in a colder air mass with surface observations showing
most temperatures around or below freezing. With the reduction of
moisture and upslope flow along the Colorado Front Range, snow has
tapered off or ceased across the region. NWS radar and
observations show more widespread light to moderate precipitation
falling to the southwest of the Four Corners region, with snow for
higher elevation terrain/mountain ranges and a mix of rain and
snow for lower elevation/valley locations. Although some
wind-related warnings and advisories are in effect in the region,
surface observations showed most winds currently in the 5-10 mph
range. The highest winds are occurring over portions of central
New Mexico, reaching upwards of 25-35 mph.

The threat for heavy snow will be more broadly over the Four
Corners Region. A closed upper-level low settling southward offset
just to the west of the region 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. Some thunderstorms will
also be possible. There are moderate to high probabilities
(50-90%) of snow totals through the weekend between 8-12", with
locally higher amounts upwards of 2 feet possible. 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 linger longest over portions of southern Colorado and
northern New Mexico through Monday, tapering off Sunday for Utah
and Arizona.

The next Storm Summary will be issued by the Weather Prediction
Center at 1100 AM EDT. Please refer to your local National Weather
Service office for additional information on this event.
