Monday AM - Tuesday AM

Cloud coverage increased on Sunday night and we're now under mostly cloudy skies and temps in the teens on Monday morning. We should remain mostly dry for the rest of the morning ahead of our first round of snowfall that will begin to ramp up through Monday afternoon.

This first wave is really just an appetizer and will open the storm door for a stronger wave that will arrive on Tuesday evening. Expect decent snowfall rates through Monday night ahead of a slight break on Tuesday morning. In total, look for 2-4 inches in Tuesday's reports, with freshies to enjoy for first chair Tuesday.

Tuesday PM - Wednesday PM

Following the slight break around Tuesday morning and into early Tuesday afternoon, we'll begin to receive the second and stronger wave beginning around Tuesday evening. This wave will bring heavy snowfall rates through Wednesday, along with gusty winds out of the west-southwest.

Even though areas to our south and west will receive the deepest totals, we should still be looking at a healthy event from Tuesday night through Thursday night, with totals of 4-8+ inches. Keep an eye on late Wednesday afternoon and into Wednesday evening for sneaky good totals as the wind direction shifts to more of a westerly flow.

Wednesday will be full-on storm skiing. First chair Thursday would be my choice for the best turns this week.

Thursday - Friday

We'll then continue to receive off-and-on snow showers on Thursday and into Friday. Highs will only be in the teens, with overnight lows in the low single digits so it will feel a lot more like mid-January compared to late March.

Travel Forecast

Dry road surfaces remain in place on Monday morning.

Slick, slushy, and snow-packed road surfaces will return around midday Monday and continue through Tuesday afternoon. Plan to give yourself a little extra travel time on Tuesday morning.

Icy and snow-packed road surfaces will form on Tuesday evening and remain in place through Thursday morning. Due to heavy snowfall rates and blowing snow, very difficult travel conditions will be encountered on Wednesday, so give yourself plenty of extra travel time and keep an eye on CDOT for road closures.

Wet and slushy road surfaces will then remain in place for Thursday and Friday. Travel should cruise along at normal travel speeds but we'll have to wait and see how things develop this week.

More icy and snow-packed road surfaces will form next weekend, March 25-26, so plan for extra travel time.

We're entering that time of year when the higher sun angle really begins to be our friend in regards to clearing snowy road surfaces during the midday hours. Heavy snowfall rates can still overcome this higher sun angle so always remember to take it slow and give yourself extra travel time while driving during heavy snow.

Extended Forecast

Next Weekend & Beyond

March Madness will continue on Saturday, March 25 and into Sunday, March 26 as another storm rolls through Colorado. We'll work on the details as we get closer but I can say that it does look very cold with temps well below average for late March.

Looking further ahead, the storm train won't stop. We should catch a short break around early next week, March 27-28, but then we'll be right back into a stormy pattern as we close out March and flip the calendar into April.

The statewide snowpack for Colorado is currently 129% compared to the 30-year median and already 10% above the median peak so we're going to be looking at a very healthy snowpack as we head deeper into spring. Great news all around.
