Snowfall map for the Sat pm to Sun pm storm system
Mar 13, 2026, 9:15 AM
03/13/26 9am: Happy Friday. Its actually looking like a decent snowfall event for the north-central mountains on Sat night into Sun. For the front-range (Den/Bou) its more uncertain as models can't decide if its going to be more northwest downslope flow vs more northerly upslope flow (with some snow). Below is my initial snowfall map valid from Sat evening through Sun evening.
For the north-central mountains a round of snow from about 6pm Sat to 6pm Sun (most of it before 12pm Sun). Generally a good 4-10" of new snow for the local ski areas favoring the Front Range mountains near/east of the Cont. Divide (areas near A-Basin, Loveland, Berthoud Pass, Winter Park, IPW, RMNP and Cameron Pass will be favored for the highest amounts).
For Den/Bou and the front-range a chance for snow showers or a brief round of light snow from about 3am-3pm Sun (best chance Sun morning). Generally only Trace-2" for the lower elevations / urban corridor, with 1-4" possible in the foothills. If we end up with more northwest flow aloft, it could be very little to none.
The storm system clears out on Sun evening.
As I mentioned yesterday very strong wind again today (this afternoon) and especially tomorrow (Sat) ahead of this short-wave.
On Sat: westerly wind-gusts of 40-80 mph for the front-range (Den/Bou/Ft.Collins and foothills), favoring the foothills.
First image is my preliminary snowfall map through 6pm Sun. Images 2 and 3 compare forecast total snowfall from now through 6am Mon from latest ECMWF and NWS Blend of Models, take amounts with grain of salt.
