We gave you the First Alert on the cold front and potential for snow last Thursday and it looks it is going to pan out.
A cold front will move through the area later Wednesday evening. Behind the front, colder air will begin to move in, winds will begin to increase and snow should start to fall.
The big question everyone has, "How much are we going to get?" This does not look to be a significant snow for southern or southeast Colorado. Generally speaking, I am looking for 1" to 3" of snow to fall through late morning Thursday. Higher elevations in the mountains could pick-up 4" to 7".
The worst part of the snow is the timing. I expect snow to start over the Pikes Peak region around 10pm tonight. The snow will the spread south across the KOAA viewing area. Accumulating snow should end by mid-morning, with a few flurries possible through late morning and early afternoon.
Here is a break-down of snow timing:
The big question I have with the snow is dry air. Dry air is in place over the KOAA viewing area. We need the humidity level to go up and support snow making it all the way to the ground. I would not be surprised for the radar to indicating snow this evening, yet none is reaching the ground. Potentially, the dry air could limit how much snow we get.
The other contributing factor to the snow is the cold moving in behind the front. Tomorrow will be a cold day. Temperatures will struggle to get out of the teens in many areas. Highs will top out in the upper teens to middle 20°s. (Colorado Springs: 20° | Pueblo: 23°)
I mentioned the cold temperatures will contribute to snow amounts. The colder, arctic air will likely cause for a "fluffier" snow. This means snow ratios could be slightly higher. In turn, this would produce higher amounts of snow (although, still within our forecast amount).
WARMING BACK UP
The cold weather will be short lived. Temperatures are expected to pop back up to the 50°s and 60°s for Friday and the weekend.
Another cold front is projected to come through Sunday night/Monday morning and we will see temperatures dropping back to the 30°s and 40°s Monday afternoon. - Meteorologist John Dissauer
