The slow movement of the second low tracking from Nevada into the Plains states will mean snows continue falling over the Colorado and Wyoming Rockies tonight and throughout tomorrow, adding to already large totals for some areas. As the system dips SE of Denver tonight, expect upslope snowfall to increase over the Laramie Range as well as down over northern and central Colorado, including the Denver area tonight and particularly through Wednesday morning.For Denver, expect 2-4 inches while up towards the Thornton area, north of the metro, 13.4 inches fell last night and through tomorrow, as much as 20 inches may have fallen here according to my twitter follower William Shererer, based in the Denver area. Up towards Cheyenne, Laramie and Casper, where these areas have already surpassed 8-14 inches already, an additional 8-10 inches is possible through the next 24 hours. [s2If current_user_can(access_s2member_level1)]Highs today only rose to 36 in Denver while it was a cold 26 in Cheyenne today. Highs tomorrow will be nearer 32 in Denver while Cheyenne, after dipping into the teens tonight, will struggle to get above 20 tomorrow. The average high is low 60s and low 50s respectively, so both these cities are running an impressive 30 below normal.

It looks as though the snow should taper off by later Wednesday and so clearer skies Wed night into Thursday, along with fresh snow cover, should allow temps to drop well into the 10s in Denver and perhaps 0s in Cheyenne with areas such as Casper and Laramie dropping close to 0.

Here’s the GFS surface/precip chart out at 18 hours, later Wednesday.

Note the focus of precvipitation very much over Southeast Wyoming still.

GFS shows big snow totals topping 2 feet in the Laramie Range.

Here’s the 48 hr
