Snow & Wind Arrive in Overnight

A cold front is moving across Utah and Wyoming Wednesday afternoon.  The cold front will begin to pass through southern Colorado during the late night/overnight hours.  Behind the front, colder air will begin to move in to the I-25 corridor and the southeastern Plains of Colorado.

There is still some question as to how warm, or cool, we get Thursday afternoon.  Computer models suggest skies turn mostly sunny.  If that does happen, temperatures will likely reach the upper 40°s to around 50°.  However, with the colder air in place, if clouds develop, obscuring the sun, temperatures may struggle to get out of the 30°s.  I am currently forecasting in the middle, highs in the 40°s.  (Colorado Springs: 41° | Pueblo: 45°)

OVERNIGHT DUSTING

The cold front will put a little squeeze on the atmosphere and wring out a few rain drops and snowflakes.  This should begin to happen late this evening/tonight.  Areas along and south of U.S. 50 could see a few isolated rain showers before eventually changing over to a little snow. Areas north of U.S. 50 will likely stay all snow.  Precipitation will be quick to move out, as it should be gone by 3am or 4am.

Snowfall amounts should be minor at best.  Computer models continue to suggest very meager moisture available for the colder air to interact with.  A 27-computer model average suggests only 0.03" of moisture for Colorado Springs and 0.01" for Pueblo that could fall as snow.  This would suggest up to a half inch of snow possible for Colorado Springs and a tenth of an inch for Pueblo.  In reality, if there is more than a dusting of snow in Pueblo I will be surprised.

HANG ON TO YOUR HATS

Along with colder air, strong winds should move off the mountains later tonight.  Data suggests winds could gust 35 to 55 miles per hour during the pre-dawn hours Thursday.  Here are a couple views of projected wind gusts by our high-resolution computer model during the overnight.

Projected wind gusts at 12am MT.

Projected wind gusts at 5am MT.

Winds will likely gust 30 to at times 50 miles per hour throughout Thursday.  With cooler air, this could create wind chills down in the upper teens and 20°s.

Try to get used to the wind as it appears it will be with us for the next several days.  Medium-range computer models indicate winds will be 20+mph through the weekend. - Meteorologist John Dissauer
