Pull up your boot straps... Hang on to your hat... Or insert any other phrase you like to use in anticipation of active weather because we've got some ups and downs coming this weekend.
If you plan to spend a day outside this weekend I suggest you do pick Saturday. Clouds will be on the increase, turning partly sunny, but temperatures will be nice this afternoon. Highs will be in the 70°s and we may even touch 80° in the southeastern Plains. (Colorado Springs: 71° | Pueblo: 78°)
Winds will begin to pick-up this afternoon gusting at times 25-30 mph.
There could also be a couple of isolated showers and/or thunderstorms this afternoon, mainly over the mountains, but an isolated shower/thunderstorm can't be ruled out along the I-25 corridor.
GOING DOWNHILL SUNDAY
A system, first advertised by the First Alert team last Sunday, will begin to affect southern Colorado Sunday morning. Colder air will begin to move in from the north. Moisture will be in place and interact with the cooler air. Initially, any precipitation will fall as rain but a changeover to snow is expected during the afternoon and continuing through the night.
Moisture appears to be plentiful for the upper-level energy to work with. A 27-computer model average suggests the following liquid moisture amounts available through 6am Monday. Colorado Springs: 0.53" - Monument Hill: 0.69" - Pueblo: 0.41" - Trinidad: 0.61"
If this were to fall as all snow, this could be a real doozy of a storm. However, since some of this will fall as rain, this will cut down the snow totals. However, in the mountains, a foot or more of snow will be possible in Teller County, the Wet Mountains, and the Sangre de Cristo Mountains.
WINTER STORM WATCH
Winter Storm Watches are in effect from Sunday morning through 3am Monday morning for northern El Paso County, Teller County, the Wet Mountains, the Sangre de Cristo Mountains and the eastern Sawatch Mountains.
Stay tuned as I will be updating the forecast throughout the weekend. More details as to amounts and the when and where's will be available on News 5 at 5:30pm and News 5 at 10pm and here on KOAA.com. - Meteorologist John Dissauer
