In Brief
Very warm dry weather all week with "maybe" a Christmas Eve storm.
Forecast Discussion:
A persistent western ridge will give us really warm and calm conditions through Friday. In Colorado, this is shorts and t-shirt weather (Figure 1). See the Longer Range forecast for what 'might' happen for Christmas.
The Longer Range Forecast:
The upper air patter for Christmas Eve, from the GFS (Figure 2) is a weird mess. I've not seen a scramble quite like this before. It gives the mountains some snow but nothing really down to I-25 by midnight Dec 25/Dec 26 (Figure 3). The Canadian model looks more 'normal' to me (but still messy - Figure 4) and gives us a whopping 8-10 inches of snow Christmas Eve (Figure 5)!!
This forecast is still very far away and there is a LOT of disagreement between the models. Send a note to Santa requesting snow for Christmas! Check back here!
