Heat, heat, and more heat! That starts our week today. High pressure has settled into the Oklahoma and Texas panhandles (below) today. A very warm airmass has also taken hold across Colorado, with temperatures aloft approaching 18°C. This is going to support highs in the mid to upper 90's this afternoon. We will see lots of sunshine with a few …

A few low-impact storms were in the area on Saturday bringing winds, some from an outflow boundary flowing southward from storms to our north.  Sunday morning a weak summer cold front backing in from the northeast will bring a bit of morning moisture to the area.  This shouldn’t result in anything more than a few morning clouds, but brief fog …

The upper-level trough over Canada and Montana will be making its way through later today and tonight. While not typical in the summer season, the jet stream is present over the U.S., signs of the autumn season slowly approaching. A trough axis currently today is over eastern Utah. That axis will push through tonight as the trough in Canada moves …

As shown in the mid-level 500 mb vorticity map below, the main trough is along the Canada/Montana border. However, embedded in the flow are several smaller shortwave low pressure systems. This will be the story today and tomorrow. As the upper trough …

The monsoon is starving! The pesky high pressure center which briefly vacationed to the Gulf Coast earlier this week has shifted westward again. It now has two clear lobes...one across southwest New Mexico and another more problematic one off the coast of Baja California. In Colorado, we remain in-between this high and weak but broad troughing in the center of the country. …

Right on-schedule Following the surge of moisture last night around sunset, a small cluster of severe thunderstorms developed near Longmont and Loveland, trekking eastward all the way to Kansas through the overnight hours. Can you spot the faint cooler airmass moving westward in the GOES-East infrared satellite animation below, followed by the explosive growth of a few storms across the Front …

Severe outbreak just east, outside chance of late evening storms for us It's shaping up to be a very active day for severe storms all along Colorado's eastern border! A low-level boundary has backed into the region bringing deeper moisture to that area. The HRRR model surface dew point forecast below is for 4:00 PM this evening. Notice the very …
