Changes for the Weekend


Short Range-
Current storm from the Southwest still on track for the weekend. Moisture will be in place over western slope of CO Friday night. Surface Low pressure position now expected to be over Central CO and will bring moisture from south to north across eastern CO and southwest NE and also along I-76 corridor for Saturday morning. Saturday noon the Low will deepen over the Rockies continuing to push moisture eastward. Saturday night the Low will move northeastward taking most of the moisture with it. Sunday morning low level moisture still hanging around leaving a possible shower or two. Sunday mid-day partial clearing skies with colder temperatures.

Saturday morning precipitation will be in the form of rain/snow/mix, take your pick, and will turn towards snow Saturday night as the cold air moves over the area. Temperatures Saturday morning will be slightly above freezing and will warm towards the noon time then drop off for nightfall due to partial clearing. Saturday max temperatures will be around upper 30's giving a cool rain process. Precipitation form may switch between rain, sleet, freezing rain, and snow throughout the day as the temperatures fluctuate. Precipitation totals for the I-76 corridor are expected to be around 0.20 inches, which may equate to around 2 inches of snow. Sunday temperatures will warm slightly to around 32 F by noon but will remain cold with clearing skies. I will update this again tonight or tomorrow morning with more details.
