For real: Our last chance of January snow! A few snowflakes did fall across the area last night after sunset, but no accumulation was reported in most areas. Still just a trace for the month in the city of Boulder. The radar animation depicting the isolated snow showers last evening is shown below. They were indeed few and far between. …

The "last hurrah" for snow in January A weak disturbance is dropping south out of the northern Rockies. You can see this system in the GFS 500mb height anomaly animation below as it tracks from near Salt Lake City this morning into Mexico by tonight. It's a quick-mover with a track that is far west of our area. Nonetheless, some …

No real change in the airmass today compared to Saturday. High pressure ridge to our south in New Mexico (below) continues to dominate our weather pattern. We should see lots of sunshine for the afternoon, though some passing clouds will start to build by the early evening and especially late evening/overnight as a weak trough from California pushes eastward.

Weak northwest flow remains this afternoon (below) across the state with a weak jet streak passing through. That should limit our highs from getting too warm. However, easily middle 50's should be the norm later this afternoon. There is some …

An uneventful Thursday Yesterday's weak cold front passed with little more than a few brief gusts of wind. Today will be a rather quiet day with northwest flow aloft. The "clipper" system that bypassed our area is now stationed across Missouri, with a ridge of high pressure to our southwest. Temperatures will rise into the mid to upper 40's this …

Less clouds, still mild The deep blob of subtropical moisture which blanketed the area yesterday has thinned out considerably overnight. We did indeed break the daily record in Denver for precipitable water on Tuesday. The morning balloon launch at Stapleton Airport measured 0.38" (below on the right), beating the old daily record of 0.33" (below on the left). FYI this …
