Warming up With the cooler airmass to our north relaxing today, temperatures will be a little warmer this afternoon. We have included two 800 mb temperature maps for Colorado below. The one on the left is from yesterday evening. On the right, this evening's map. Notice the easterly upslope yesterday which allowed for cooler temperatures across the region. In the Boulder area (within …

One more cool day Yesterday ended the streak of 4 consecutive 90-degree days in Boulder and 7 consecutive 90-degree days in Denver. Despite a large dome of high pressure remaining in control across the Texas Panhandle again today, a large trough skirting across Montana and Canada to our north continues to funnel cooler air into northeast Colorado. The 800 mb temperature …

Mostly Sunny skies today with highs in the upper 90's this afternoon. This will be our last hot day before some cooler air slides in tomorrow. Unfortunately the reprieve will not last long. We are also watching the threat of some storms come midweek. There is a wildfire that has developed near Durango. It has currently burned over 8000 acres. …

An upper-level trough will be pushing into the Pacific Northwest, with the southern branch of the jet reaching western Colorado Sunday evening. The jet stream overhead will …

Another hot one across the region today. A mixture of clouds and sunshine this afternoon, with temperatures once again in the lower 90's. Below shows that the area of high pressure is situated in western Texas. That puts Colorado in a region of southwesterly flow, helping to pump in the desert heat. Another view of this is shown below, looking …

Who's ready for another hot one? The 500 mb ridge remains across central Texas...the same location is has been all week long... The slightly cooler airmass that was in place yesterday across northeast Colorado has moved out. Very warm conditions will return with temperatures this afternoon pushing into the low to middle 90's across the Metro area. The 850 mb temperature …

We're hard-pressed to call the shallow low-level upslope pushing into the Metro area this morning a cold front, but that is technically what it is. This frontal boundary is associated with a very weak disturbance moving across the region today. We mentioned this piece of energy in our weekly outlook. On the NAM 800 mb temperature map below, we have …
