surface trough was also analyzed in Colorado with a couple of

embedded areas of low pressure. Heavy snowfall is ongoing across

A cold high pressure settling over the northern Rockies in

conjunction with multiple lows across New Mexico and the Great

Plains will continue to foster a tight pressure gradient, keeping

winds strong out of the Northeast. This pattern will lead to

rising motion (upslope flow) over the Rockies and continue to lead

to heavy snowfall through the day on Friday. Once it is all said

and done, WPC key messages are expecting locally 2-4 feet of

snowfall across the Central/Southern Rockies and intense snowfall

rates of 2 inches per hour. Winds are also forecast to remain

high, gusting over 35 mph, and will make travel conditions nearly

impossible with the snow. Moreover, part two of this event will be

an upper level low and surface low moving eastward across the

Southwestern US. Heavy snowfall is expected across elevation in

the Four Corners Region, with high probabilities of eclipsing a

foot of snowfall. 



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.
