A quiet day once again. The atmospheric pattern today is provided below in the 500 mb absolute vorticity plot. Zonal (westerly) flow is present across much of Colorado today. That will spell out another dry day for the Plains. However, mountain snow will be the norm to our west as west-northwest winds embedded in a weak shortwave today/tonight touches off …

Calm weather on this Saturday. High temperatures will be in the lower 40's under Sunny skies to start. Clouds will move in for a mixture of high clouds and sun for the afternoon/evening hours. Over the couple days, a series of weak low pressure systems will trek through the region. The first comes through tonight (below left). Its track will …

Only a trace of snow accumulation expected today before the system pulls away. The main story will be colder air to end our work week. With the exception of the GFS model, the majority of the guidance is showing little if any total snow accumulation today (below). Expect isolated light snow showers for the morning commute, but only a dusting …

Breezy today and warmer The jet streaks responsible for the high winds over the weekend, yesterday, and early this morning have pushed off to the east. The GFS 250mb wind forecast animation below spans from this past Saturday evening through this afternoon.

After a windy end to Saturday, where peak wind gusts prior to midnight reached 50 mph in parts of Boulder (below) and the Front Range, we end the weekend on the chillier side. Highs will top out near the lower 40's with weak easterly surface winds advecting in colder air from last night's frontal passage. We'll see a mixture of …

Warm day to start our weekend on this Saturday. As mentioned yesterday, a nice downslope flow continues today and brings in further warmth compared to Friday. Yesterday, highs were in the middle 40's. Today, we'll likely reach the upper 50's, with some locations briefly reaching 60 degrees (below right). We'll start the day, however, likely with a potentially gorgeous wave …
