Welcome to meteorological spring, which runs from March 1st to May 31st. Those convective clouds yesterday really set the mood for the seasonal transition! Click for time-lapse video from yesterday's clouds. A ridge axis is passing directly over Colorado today. This will lead to westerly flow, warmer conditions overall and a return of mostly sunny skies. Temperatures will be in the …

Light snow is falling up in the Mountains today as a weak trough axis moves across the state. The main source of energy is currently located well to our south near Phoenix. The track of this system and limited moisture overall means meager snow totals for the Mountains, generally less than 1" for northern Colorado. The animation below from GOES-16 shows the …

Today's weather will be very similar to yesterday as little change has occurred in the atmosphere over Colorado. Highs again will be in the lower 50's with sunny skies. A cut-off system is situated over southern California today. This low will track across southern Arizona and New Mexico tomorrow, weakening in the process. The system as a whole has very limited moisture to work …

Don’t let the sunny skies Friday morning fool you. Similar to the snowfall event on President’s Day, atmospheric components will briefly align this evening for banded snowfall to once again form across the Front Range. The Northwest Metro area appears to be favored again by the models, including Boulder, Louisville, Longmont, and Broomfield.

The current troughy weather pattern looks great on paper....However, there is almost too much meandering in the flow. The trough across the western United States is projected to hold strong for the next week or more. The 500 mb height anomaly animation from the GFS model shows the trough persisting through early March. The problem is, the bulk of the energy …

Today will be the quietest weather day of the week...the only one where we can fully rule out the chance of snow. The 500 mb vorticity map for this afternoon shows an expansive trough across the West, and a blocking high off the South Carolina coast. Calm, unperturbed southwest flow is in place across Colorado. This will translate into mostly …
