The coldest air in nearly four years is set to arrive later this week. Along with the cold air, snow will be possible over parts of the southern Colorado area.
Temperatures climbed in to the 50°s and 60°s Monday afternoon. I hope you were able to enjoy it because big changes are coming our way. In fact, temperatures will likely drop 55° to 65° degrees from Monday afternoon to Thursday morning.
A cold front is expected to move through southern Colorado Tuesday afternoon/evening. Before the front passes, temperatures will likely climb in to the 50°s and 60°s once again. (High for Colorado Springs: 52° | High for Pueblo: 59°) Once the front passes temperatures will start to drop off.
The cold arctic air will lag behind the front but should be in place by Wednesday morning. Temperatures Wednesday afternoon will likey struggle to get out of the teens across the area. There will also be a chance for snow showers developing during the day.
Current snow thoughts:
The biggest concern with the cold air is the projected duration. Cold air isn't uncommon in Colorado. However, we will likely see temperatures stay below freezing for 136 to 140 consecutive hours. In fact, I am not forecasting temperatures to go above freezing until the afternoon of December 9.
