Overview: We’re tracking another storm that will bring many areas wind, rain and snow. Next week starts chilly and we cannot rule out more snow at times for some areas before we finally start to warm up again late in the week.
Today: As the storm crosses over the mountains it will intensify with increasing wind, rain and snow through the day. Precipitation will develop over the Pikes Peak Region early this morning and then spread south and east the rest of the day. Snow will accumulate best on the higher terrain surrounding both Colorado Springs and Pueblo today due to the warm nature of the storm. We could see as much as 3”- 6” or 4”- 8” of snow by the time this storm wraps up over the foothills of western El Paso and Teller County mainly northeast of Pikes Peak, and the Palmer Divide could also receive 3"- 6" although the higher amounts in all cases are likely to be spotty and as a result of localized bursts of heavy snow. Heavier amounts are also possible a little later in the day into early tonight near the Wet Mountains. The snow will be very wet around Colorado Springs so we are more likely to receive lesser accumulations on the order of 1”- 4” with much of that likely confined to cooler surfaces. Canon City and Pueblo are likely to have a mixture of rain and snow with maybe even some thunder today, and although some bursts of heavy, wet snow are possible, it looks like the relative warmth of this storm will limit snowfall accumulations to probably an inch or less on mainly cooler surfaces.
This will be an interesting storm for the plains along the Arkansas River to the east of I-25 today. Although it looks pretty warm for much snow today, it also looks like the center of the upper level circulation will track near the Arkansas River to the east of I-25 into this evening and it is possible that enough cold air will exist within this circulation to allow for rain to change to heavy, wet snow under stronger bursts. It's hard to know where exactly these bursts will occur, similar to trying to predict where individual thunderstorms will develop on any given summer afternoon, but where they do we could see a couple inches of snow on the cooler surfaces at least with some slush on the roadways.
Temperatures Sunday will range from the 20s over the mountains to the 40s over the plains today with pockets of cooler air under areas of heavier precipitation over the plains. Under areas of heavier snow roadways are likely to become snow packed over the higher terrain while at lower elevations heavier snow will more likely cause slushy roadways. It will be windy so some blowing and drifting snow could be expected, but the wet nature of the snow will limit this some.
Tonight: Rain and snow will wind down over the southeastern corner of the state where most of the precipitation will continue to fall as rain or a mixture of rain and wet snow. Residents on the eastern edge of the Raton Mesa could receive 1”- 4” of snow before everything ends. As the sky clears and the air cools wet roadways could become icy. Low temperatures should fall into the 20s for most areas with some teens possible on the higher terrain.
Extended: A quick moving wave will race over Colorado Monday bringing gusty wind to many areas. While most of the snow looks to fall over the ski resorts in northern and central Colorado with this wave on Monday it is at least possible that we'll get clipped with a quick burst of wind driven snow that could impact the Monday evening commute for some of us. If this wave misses us to the northeast we should still expect gusty wind and falling temperatures late Monday. Tuesday looks cold and we still cannot rule out at least some scattered snow showers at times. We'll need to track the western extent of another wave late Wednesday and Thursday but right now it looks like this will slide just to our east which would leave us potentially a bit windy but mainly dry. We should warm significantly by the end of the week into early next weekend.
