One last warm day before colder air settles in again. Below shows the 800 mb temperature map for midday today. A deep low is centered over North Dakota, with a trough axis sagging southward and southwestward. A cold front will be dipping through the area early this evening, likely around 5 PM. Highs today will reach the middle 50's under lots …

Temperatures warming a tad this afternoon. As you can see below, the west is under a bit of some weak ridging, allowing southerly flow to develop this afternoon under plentiful sunshine. A low pressure exists over Minnesota, with a second over southern Arizona. A third system is located upstream in Washington - this will be our player for the weekend …

Quiet day as snow stays east of Metro area As expected, nearly all of the snow showers overnight remained east of the Metro area. It is possible there could be a few flurries in and around Boulder and Denver given the radar echoes indicated, but nothing of impact. The best energy from the passing trough, frontogenesis, and jet forcing will quickly …

If we take a look across Pacific Ocean today at 500 mb, we see a highly pronounced ridge extending northward from the eastern Pacific into the Arctic Ocean. A ridge this amplified typically will shoot down …

It sure has felt like fall lately! Most of the leaves are off the trees, we're starting to get much cooler nights, winds are "randomly" gusty at times, and the wave clouds are prevalent. It's also looking like fall in the weather models, with a sharp delineation between the summery and wintry air masses. Today's 700 mb temperature map is shown …

While things appear quiet, the atmosphere will be quite active today and tonight. Below shows the GFS 250 mb upper-level winds and jet stream over the region and the western US. A strong northwest to southeast oriented jet stream is positioned from the Pacific Northwest, southeast into southwestern Colorado. West and northwestern parts of Colorado will be located on the …

Rain showers ending by noon-time today, followed by partly to mostly cloudy skies and gusty northerly winds. The HRRR model shows that the north winds will at times be 20-30 mph. Winds should decrease later today and tonight as the direction turns more southerly. Highs this afternoon will be near the lower 50's.
