Winter Weather Update: Following this 70-degree Wednesday, rain will change to snow late tonight

A potent atmospheric river event is ongoing across the southwestern United States right now including portions of western Colorado. After our warmest day in more than four months on Wednesday, this moist system will enter the picture for the Front Range Wednesday night with rain changing to snow across the Plains and Foothills as a cold front slides through. Though the best upslope will be south and southwest of Denver with this event, most everyone will see snowflakes amounting to a several inches in some places and just a dusting in others. Let’s take a look at the expecting timing of the change-over to snow, snowfall amounts, and the travel impacts in the works as winter weather returns to the Front Range.

BoulderCAST Daily – Tue 03/14/23 | Spring-like warmth begins today, but the snow outlook has waned

The highly anticipated yet brief springlike warm spell begins today across the Front Range as deep southwest flow surges into Colorado out ahead of an approaching Pacific trough.

Colorado Weekend Weather Outlook: March 9, 2023

The main shortwave trough axis has passed to the east of Denver early this morning bringing just a few snow showers to the Mountains and the far eastern part of the state.

BoulderCAST Daily – Wed 03/08/23 | Overcast and cold today, strong winds take hold tomorrow

Southeasterly upslope flow and cooling temperatures overnight have once again forced low clouds and patchy freezing mist upon the area, but for the most part this has been confined to Larimer and Weld Counties. Surface visibility observations early this morning show that the primary trouble spots are indeed up along the Wyoming Border region. There could be a few slightly …

BoulderCAST Daily – Tue 03/07/23 | Gloomy, foggy, freezy & misty

Upslope and low-level moisture have intensified overnight across eastern Colorado with low clouds, fog and freezing drizzle/mist developing across much of the Front Range. GOES-East satellite shows that almost everywhere east of the Continental Divide is socked into the stratus deck this morning, up to around 9000 feet elevation or so (white shading below is beneath the upper-level clouds). Current …

BoulderCAST Daily – Thu 03/02/23 | Staying cooler than normal but at least it’ll be sunny

Yesterday's wet snow came and went without much of an issue as primary roadways generally stayed just wet. The developing snow was heavy in spots, but was slightly more sporadic than expected. Some portions of southern and eastern Denver didn't see any snow stick at all, while pretty much all of Boulder County and the northern Metro area saw light …
