Chilly air was in place for a day, post-cold front on Thursday. Our cold front is being pushed across the Midwest U.S. by the upper air trough (the lower red line in Figure 1). The signs of things to come are visible as the blue line ridge off the West Coast (we are very familiar with that ridge this year).
That upper trough (the higher red line) will kick off mountain snow today and lower elevation winds as it races through today. Figure 2 shows those, mostly western slopes and higher mountain, snows. Figure 3 shows the strong winds up and down the Front Range for today.
The longer range forecast:
On Sunday, the western ridge is closer (Figure 4) and another northern trough is coming down to give us a brief chance of rain/snow on Monday. Figure 5 is the upper air pattern for Monday and that trough is sweeping by already. As with most of the storms this winter… I don’t expect much from it due to lack of moisture and quick passage. But we’ll keep an eye on it here!
