Tonight: Cold frontal passage will happen at about midnight tonight, transporting January like temperatures to Colorado with high temperatures in the 20s and 30s through Wednesday. The cold front will also whip up those winds with gusts to 30mph across the I-25 corridor with winds becoming calm throughout the day on Sunday.
Sunday morning/early afternoon snow flurries are possible but with minimal accumulation in El Paso County. Winter Weather Advisories along I-25 begin at 4pm with moderate to heavy snow beginning after 6pm. Temperatures Sunday night will reach to about 15 in Colorado Springs, which is 2 degrees away from the record low of 13 for 10/28 set back in 1991. The cold temperatures will also make it more likely to see snow accumulation on the roads for the Monday morning commute. The Heaviest periods of snow will be from midnight Sunday till 9am Monday morning, with tapering snow flurries through early afternoon. The total snow accumulation forecast is as follows. Colorado Springs 4-10″ with areas above 7000ft on the higher end of that forecast. Downtown Colorado Springs will likely see 4-6″. Woodland Park 6-10″. Pueblo 3-6″. Canon City 5-8″. Sangre De Cristo/Wet mountain ranges 12-16″. Alamosa 1-3″. Lamar trace-1″.
The biggest concern overall will be for the Monday morning commute. Limited visibility in the heavy snow bands and snow-covered roads will make for hazardous driving conditions.
