We'll be starting out a little warmer this morning due to a thick deck of mid and upper-level clouds present across the area. These clouds are associated with elevated moisture embedded in the southwest flow that is established aloft. The southwest flow is a result of today's major weather feature transiting across the Rockies: a weak but absolutely bone-dry trough. …

A milder Wednesday High pressure is now fully in-control across Colorado. The closed, clockwise circulation of the high is easy to identify in today's 500mb map below. By 5:00 PM this evening, the center of the high will be across southwestern Kansas. Further west across the Great Basin, a weak trough is brewing. This trough will move through our area …

The stretch of brief ridging that began Monday night will come to an end this evening as our next quick-moving trough passes from east to west across the Rockies. The NAM 500 mb vorticity animation below spans from this morning through tonight. Notice that initially a small-scale ridge is present over the Front Range. The main trough axis is poised …

Stuck between a trough and a ridge As is almost always the case when we sit between an exiting trough and an approaching ridge, northwest flow is present across Colorado for our Tuesday. Unlike yesterday, the flow has lost its moisture and won't be producing any snow across the Mountains with dry conditions prevailing statewide. Highs will be in the …
