We’re headed to northeastern Colorado for today’s forecast. It looks like things could get a little active today, so let’s see what’s going on.
At 1255PM, MT, Greeley was reporting a temperature of 19 degrees with overcast skies. Snow was being reported across the Front Fange, but it hadn’t been able to develop north into Greeley as yet. There is a sharp lee trough along the ridge line, but the real culprit for snow showers was high pressure developing over the Plains.
Aloft, a jet driving southeast towards Arizona is aiding with the development of an area of low pressure over the 4 Corners, on the other side of the Rockies. Snow showers will blossom over western Colorado today, and will only serve to reinforce the easterly upslope in eastern Colorado. Snow will develop over Greeley this afternoon, and will continue even as the surface wave moves into west Texas. Snow showers will diminish overnight Friday, but deeper, broader upper level trough will move into the Great Basin through the day Friday, allowing for a vast system to begin forming over Nevada. This system will eventually be a significant system for the center of the country, but it will take its time becoming an issue for Greeley, with much of its associated snowfall remaining south of the Palmer Divide until Saturday night. High pressure combined with upsloping will lead to very cold temperatures.

You know, I’m going to stick with model guidance on this one. I don’t see anything that makes me want to give Greeley warmer temepratures. They are out in the plain and are more exposed to the cold air and advection. We’ll see if this gambit pays off. Here is the radar, showing snow smothering Denver.
