Nearly the entire continental United States, with the exception of the extreme western coast, is entrenched today within a mid-level trough of low pressure. The trough axis extends southward from the Hudson Bay in eastern Canada, into the Gulf of California. It's actually fairly remarkable!  This trough is bringing a somewhat rare occurrence of northeasterly flow at 500 mb to Colorado.... …

We have a VERY dry airmass in place today across Colorado. Column water vapor readings are only around 0.05 to 0.10"....about as low as it can get in Denver! The 500 mb vorticity map below shows an elongated trough stretching from the Great Lakes, south and west into southern California. Cool northerly flow is in place aloft across Colorado. With …

Big change is in store in terms of the weather starting tomorrow! But before that happens, we are going to end the weekend with the warmest day - expect temperatures in the upper 60's in most areas of the Plains and upper 50's in the Foothills. The below mid-level pattern shows that this is in large part due to southwest winds …

Not much change in the weather pattern today. We are again south of the polar jet stream, which keeps the cold air to our north in Wyoming, Montana, and the Pacific Northwest. We should see a mix of clouds and sunshine again today with lower to middle 60's. We are still watching the potential for snow on Monday as the …

Today is the first day of December. But it certainly won't feel like it with temperatures above average. Below shows the pattern across the CONUS today. Colorado is between two jet streams, (1) the polar jet stream stretching west to east from Oregon through the Dakotas, and (2) the subtropical jet stream from Arizona into Kansas and the southeastern U.S. …

We close out the month of November on a calm note! West northwest flow will be in place through the depth of the atmosphere. Temperatures will be pleasant in the 50's today with beautiful blue skies. The animation below of 850 mb temperatures from the GFS ensemble begins today and runs through Sunday. Very warm conditions will persist for the next …

What a change a day makes with the passage of a cold front! Yesterday's highs were in the middle 70's in most areas on the Plains. Today, we will struggle to get out of the low to middle 40's. A few snow showers/flurries are possible in the morning, but little or no accumulation is expected. The main story is the …
