####018006076#### ACUS41 KWBC 151452 SCCNS1 Storm Summary Number 3 for Rockies and Four Corners Storm NWS Weather Prediction Center College Park MD 1100 AM EDT Fri Mar 15 2024 ...Heavy snow tapers off over the Front Range of Colorado as 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. Winter Weather Advisories are in effect for higher elevation/mountain range regions of southern Utah, southern Colorado, northern New Mexico, and northern Arizona. High Wind Warnings and Wind Advisories are in effect across portions of Utah, southern Colorado, northern Arizona, and northern New Mexico. For a detailed graphical depiction of the latest watches, warnings and advisories, please see www.weather.gov At 1000 AM EDT...A cold front has pushed 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. Moisture and upslope flow has come down along the Colorado Front Range as the front moves further away from the region, with NWS radar only indicating some light lingering snow showers in the region. However, as a deepening upper-level closed low begins to settle further southward over the Southwest, NWS Radar shows more widespread light to moderate precipitation picking up around 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. ...Selected preliminary Storm Total Snowfall in inches from 700 AM EDT Wed Mar 13 through 1100 AM EDT Fri Mar 15... ...COLORADO...

COW CREEK 57 PINE BUTTE 57 ROCK SPRINGS 55 CHEYENNE AIRPORT 40 RAWLINS AIRPORT 38 As snow comes to an end along the Colorado Front Range, part two of the winter storm will pick up as the threat for heavy snow shifts southwestward 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 (50-80%) 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/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 PM EDT. Please refer to your local National Weather Service office for additional information on this event. Putnam $$
