A single red-rose in a backpack at the 11th annual Valentine’s Day free-marriage ceremony at the Denver Clerk and Recorder’s office on Feb. 14, 2018.

It will feel like Mother Nature has a heart as temperatures warm up into the 50s on Valentine’s Day.

Denver’s temperatures were trapped below freezing on Thursday, but sunshine is forecast for Friday, with a high temperature of around 51 degrees in downtown Denver, said the National Weather Service in Boulder.

The warming trend will continue in the first few days of Presidents Day weekend, but it will end with snow showers on Monday, forecasters said.

The holiday weekend will begin on a good note, with sunshine and a high temperature of around 42 degrees on Saturday. It will be even warmer on Sunday, with an expected high of about 50 degrees.

But Sunday night it will cool down to a low of about 27 degrees and there’s a 20 percent chance of snow after 11 p.m., the weather service said.

On Presidents Day Monday, the chance for snow will increase to 50 percent. The high temperature will be near 38 degrees, the NWS said.

Snow showers could also fall on Tuesday, mainly after 11 a.m., according to the NWS. The high temperature won’t get above freezing. The high will peak at around 30 degrees.
