My confidence has increased over the past 48 hours in regards to the probability for accumulating snow to fall during the late Tuesday to early Thursday time period next week.
At the moment it looks like rain or a rain/snow mix Tuesday night is likely to change to all snow by the early morning hours Wednesday, continuing throughout the day, with high temperatures in the low-to-mid 30s -- as a strong cold front and upper-level low conspire with surface high pressure to provide plenty of moisture and a supply of enough cold air.
Several inches of accumulation appears possible at this time, with areas from Denver northward more likely to pick up several inches or more than areas further south. This may be an instance where Fort Collins does better than Boulder or downtown Denver, at the latter two locations due better than locations further south, primarily due to the fact that cold air will spill into the region several hours earlier towards the Wyoming border than points further south.
