DENVER (CBS4) – We have a very cold Saturday en route to eastern Colorado and believe that another surge in arctic air will push into the plains for Valentine’s Day. Most locations along and east of Interstate 25 will keep temperatures at 10 degrees or less throughout the weekend.

The map below shows the upper end of the potential high temperatures in Metro Denver today. This card is generous. In fact, we may not even get that warm. Some places could stay below 5 degrees.

As we approach Saturday afternoon, snow will develop along the Front Range as a storm system moves in from the western United States. The snow is expected to last through the night until Sunday morning.

The National Weather Service has issued a winter weather advisory for all of eastern Colorado, including the entire urban corridor of Interstate 25. We expect very light, fluffy snowfall, with most of Metro Denver potentially in the 3 to 6 inch range got.

If a second cold spell hits overnight, temperatures will drop well below zero by Sunday morning. Just add a light breeze and we could see the wind chill levels drop in the -20 to -30 degree range.

It is important that you protect people, pets, and pipes this weekend. Large animals that cannot get inside need sturdy shelter and water that won’t freeze.

Valentine’s Day will be the coldest ever recorded on the Denver climate record, as high temperatures can be difficult to reach between 0 and 5 degrees. On Sunday evening and early Monday we could observe temperatures close to -20 degrees in some areas in which there was a partial clearing. If we stay cloudy, the lows are likely in the -6 to -12 degree range.

It will take a few days, but by next weekend it will be warmer again, with highs closer to where they should be for this time of year. Stay with CBS4 for the latest forecast information.
