Nicer weather today. Yesterday we had that nagging northwesterly wind, making it feel chilly out there. Today, southerly flow returns. The mid-level pattern (below) indicates an area of low pressure still offshore of California. To the east of it, southwest winds are in place over Colorado, noted by the yellow arrow. This southwest wind will advect in some mid-level moisture. …

Strong gusty winds woke us up this day thanks to a tight gradient and the jet stream overhead from west to east. Below shows the 500 mb height pattern today. The system which brought the front and brief rain showers through last night has pushed into Missouri and Iowa. Westerly flow still remains over the state though. A second system …

We also have a disorganized subtropical jet stretching across southern Colorado (see below) which may lead to isolated banded snow across the higher elevations through the day. …

As you can see in the 500 mb height anomaly panel below, a ridge axis is passing over our region this morning and flow will be turning increasingly southwesterly and growing stronger through the rest of the day as a trough approaches. This southwest flow actually contains a narrow plume of moisture which will help spread snow across the Mountains today. This …

It's another bitter cold morning across the region. Overnight lows bottomed out anywhere from 5 to 20 degrees below zero in the Metro area. Boulder set a new record low for the date, and it is likely many other cities did as well. The cold airmass in place now is rather remarkable. It's no small feat to obtain double digit below …

Very light snow continues to fall across portions of the Front Range this morning, including Boulder. Temperatures dropped slightly below zero in most locations around sunrise. The record low temperature for March 3rd in Boulder is -4°F. I don't think we quite got there but we will have to wait and see. Overall, snow totals came in on the low side, …
