Well, the long holiday weekend comes to a close today. But not before it ends with a bang! Below shows the mid-level pattern for this afternoon. A large high pressure ridge is centered over Arizona. This will lead to southwesterly flow once again across the state and return high temperatures to the lower 70's over the Plains. We are expecting …

A tad cooler today across the region as a weak cold front pushed through last night. Yesterday's airmass featured approximately 14 degC warmth in the low-levels. Today, the airmass has cooled to around 6 degC (see below image). That in turn will drop our high temperatures some 10 degrees or so to around 60 degrees for this afternoon. We certainly …

A windy forecast is the main story for this Black Friday! A strong 140+ mph jet (see below) is punching into the state from California and will usher in very windy conditions across the High Country and Foothills. The jet will also bring in a cold front this evening (more on that below). Across the High Country and Foothills, wind gusts …

The key factor in today's forecast is the strengthening ridge of high pressure across Baja California. The northwest flow should help to produce cloud cover near and west of the Divide today, with maybe even a few isolated snow showers. …

A weak disturbance is moving across southern Wyoming this morning with impacts stretching southward into northeast Colorado. A weak cold front moved through overnight, and we could see a few isolated showers this morning as a result. Snow levels won't drop much, likely only down to around 9,000 feet. The slight threat of rain for Boulder and Denver should cease …

Warmer weather today and another sunny afternoon across the Plains. Thanks to westerly downslope flow (see below) returning today, the sinking air will help warm the airmass over the region. This coupled with sunshine should lead to upper 50's in most areas. Some locations in the Denver Metro and eastern Boulder counties may also reach the lower 60's. West winds …
