In Brief:
Chilly weather turning cold Wednesday, small chance of a White Christmas.
Sunday Update:
Just a quick reminder that a powerful cold front is on its way for about sunset Wednesday (Figure 1 update). We'll see some snow from this system as well, but temperatures might drop as low as -15 to -20 on the Plains with this one (Figure 2 update). Snow won't be the main focus of this storm, but with temperatures that low, we'll see higher snowfall ratios (water content to fluff depth). More 15:1 than 10:1. This might give I-25 locations 3-5 inches. More later!
End Sunday Update.
Forecast Discussion:
Temperatures remain below normal or just getting to normal for the next week. Clouds come and go but snow/rain is not expected along I-25 for six days (Figure 1).
The Longer Range Forecast:
A strong cold front arrives Wednesday dropping temperatures to below freezing again (Figure 1 dotted line) but the shallow very cold air won't make it very high into the mountains (Figure 2). Snow over the next five days will be light and confined to mountain locations (Figure 3). Over the next 10 days (including Christmas) we'll see more northern mountain snows and snow out on the northeast plains (Figure 4). That doesn't look like much snow on the ground for Christmas, but there might be snow falling nearby on Christmas morning (Figure 5). We'll keep an eye on it here!
