Colorado sits between troughing on both coasts of the U.S. Over us, ridging extends into Colorado and over much of the northern Great Plains. Mild weather continues to build eastward for our Friday.

The passage of the cold …

Behind it, some slightly below normal temperatures but roughly seasonal with low 50s for highs this afternoon and Sunday. Lots of sunshine is expected, although some clouds may increase Sunday. We keep looking at the …

Premium BoulderCAST Daily – Fri 11/15/24 | Ending the week in the 50s ahead of a dry cold front on Saturday

We end the work week in a mild southerly flow. A fairly robust and strong trough over Nevada and Utah today will slowly track into North Dakota by midday Saturday. As that happens, a gusty southwest flow will persist over Colorado today. There could even be some gusts at the surface tonight above 20 mph. NowCAST shows a broad area …
