Records Highs in Denver

  • December 1 - Record High: 73°F (1973). Possible: 69-73°F.
  • December 2 - Record High: 74°F (1885). Possible: 70-75°F.

Sunday Shortwave

The GFS remains a lone outlier calling for light snow in northern Colorado on Sunday morning. Most of its ensemble members disagree with this.

We removed the potential for snow entirely from our snow planner for Sunday.

Monday-Wednesday Storm

Better agreement in regards to a storm late Monday (the 6th) into Tuesday – though still a ton of uncertainty. More of an open wave, with the GFS coming on board, though still has a further south track with better snow totals and a decent shot of snow for the urban corridor.

Less likely to feature southwest flow and decent totals for the south San Juans.

Friday-Saturday Storm

Another storm in the Friday to Saturday range is possible, though likely less strong.

More Active Pattern?

No compelling evidence yet that the pattern will become particularly more active after the two storms next week. Not totally dry though.
