Locally up to 3 inches of rain will be possible, and may result in ponding in ditches and low lying areas.

From Chief Meteorologist Steve Hamilton:
Update: My Mountain Town Weather...
Winter Weather Advisory - Purple on map
Winter Storm Warning - Pink on map
Here's the deal on this interesting spring storm we have going on. The National Weather Service has issued a Winter Weather Advisory until Noon Wednesday.

Keep in mind, with most of the Foothills expected to get a rain/snow mix, with occasional rounds of all-snow, and also banding snow, and heavy snow showers, predictions on totals are going to be very difficult. As much as 14 inches will fall in some areas like Conifer, Fairplay, Alma and Como. Lesser amounts are likely elsewhere, although some spots could get significant snow in the 3 to 10 inch range.
The best snowfall potential will be tonight into early tomorrow, above 7,500 feet, with mostly a rain/snow mix elsewhere. Nature talks, and we listen. Just take it easy on the roads and be prepared for potentially heavy snowfall.

Forecast Summary:
The Winter Storm Warnings and Winter Weather Advisories will expire around Noon on Wednesday. The low pressure system over the Southern Plains will be moving east, and high pressure will enter our area from the west. That will clear things up in the Foothills during the afternoon and evening. With the temperature variations, precipitation will range from snow, to a rain/snow mix, or all rain. However, all precipitation will be ending by Wednesday afternoon. High pressure moves in Wednesday night, with chilly temperatures. Then, Thursday and Friday look fair, with a warming trend into the weekend.
