https://www.koaa.com/news/covering-color...n-colorado Snow in September? Here's our forecast thinking for Southern Colorado By: Alan RosePosted at 10:35 PM, Sep 06, 2020 and last updated 1:35 AM, Sep 07, 2020
As the forecast becomes clearer tonight, everything is lining up for a summer snow storm early this week for Southern Colorado. Due to our current heat wave, the snow might have a hard time sticking on roads and sidewalks. But before it's all said and done, there's the potential for a big, heavy wet snow event for some areas. A powerful cold front that will bring a significant change to our weather pattern beginning Tuesday will push through Southern Colorado after midnight, sweeping south through very early Tuesday morning. Powerful north wind gusts of 30-50 mph will develop behind the front. It's even possible that we could see isolated gusts to 60 mph for parts of El Paso, Pueblo, Crowley and Otero counties between midnight and 6 am Tuesday.
As the cold air filters in and the airmass becomes saturated, snow will start around the Palmer Divide and points north by mid to late morning. With the north wind component, these areas could see quite a bit of snowfall. As the precipitation moves south and encounters warmer air (so to speak), we'll likely start out with a rain/snow mix for southern El Paso County and the lower elevations.
Once the colder air settles in late Tuesday, most areas will see a changeover to snow. I think that this will take place late Tuesday afternoon or Tuesday night, which is when we'll see the heaviest snow. How much snow we accumulate will largely depend on where the low pressure system sets up. Our current thinking is that the low will dive into Utah Tuesday morning, and then wobble around the Four Corners region until at least Thursday afternoon. This could send us additional snow showers (or rain) on Wednesday, possibly even Thursday.
