Wintry Weather Off To The North And Far Northeast Today

A developing winter storm is impacting Wyoming and Colorado today and will spread blizzard-like conditions eastward across Nebraska and Iowa. Webcam view (above) this morning shows I-80 at Rock Springs, Wyoming, while that down at bottom shows Pagosa Springs, Colorado.

For Tucson, the airport GEFS plumes from 00 UTC last evening can be categorized as chaotic for the end of February and start of March - some possibilities of precipitation, but with wide spread in both timing and amounts. Forecast below is for total precipitation from 00 UTC WRF-GFS on the 5.4 km grid through 05:00 pm MST on March 2nd. The model forecasts most activity for the mountains to our north and far north and little over lower elevations from Texas and Mexico westward to southern California.
