You just never know what you are going to get with the weather in Denver and we see that in our look back at the Denver weather history books. From cold and snow to damaging winds and spring-like temperatures, we can and do see it all.

Snowfall totaled 8.8 inches at Stapleton International Airport with most of the snow…8.6 inches…falling on the 28th. Strong north winds gusting to 46 mph whipped the snow into 2-foot drifts and reduced visibility in blowing snow. The foothills received up to 18 inches of snow. The snow fell on a weekend…so closures and other disruptions were minimal. The public reported thunder in Arvada…Wheat Ridge…and Boulder on the evening of the 27th. A thunderstorm produced snow pellets at Stapleton International Airport during the early morning hours of the 28th. This was the first thunderstorm in the city during January since 1932.

Thornton’s weekend to starts breezy but be overall seasonal

Friday, January 26th, 2018 5:23am MDT

The last weekend of January will offer up weather largely devoid of any drama. We will have a good bit of wind today but after that, things look to straighten up and be pretty typical for this time of year.

For today we’ll have mostly sunny skies above with a few clouds due to mid-level moisture. Temperatures will top out in the low 40s, a bit below normal. Probably the most notable thing winter-wise today will be the breezy winds that will occur throughout the day. Tonight, the winds will ease and we will have partly cloudy skies above. Temperatures will be chilly with lows around 20 degrees.

Saturday will bring mostly sunny skies above again with highs right near the average for the date of 44 degrees. Winds will be much calmer. Saturday night into Sunday morning look for partly clear skies and lows in the low to mid-20s.

We close out the weekend on Sunday with the nicest day of the three-day period. Mostly sunny skies will be above with highs in the low 50s.

Have a fantastic weekend!

Thornton’s Thursday to warm up nicely, still offer a good bit of cloud cover

Thursday, January 25th, 2018 5:05am MDT

Thornton’s Thursday to warm up nicely, still offer a good bit of cloud cover. A nice little temperature jump is in store for us today with readings 10 degrees or so warmer than yesterday. Unfortunately though, we do expect that mountain wave cloud to redevelop keeping those skies obscured.

We start the day with mostly sunny skies but soon will see the wave cloud develop and linger through much of the day. Winds will be relatively light and out of the southwest. Temperatures start out this morning below freezing but then will steadily climb toward a high close to the 60 degree mark.

Tonight, partly clear skies will be above, temps dip to the mid-20s.

Previewing your weekend, a weak disturbance moves in tomorrow that will cool things back down and offer up some wind. Saturday will remain cool but seasonal then Sunday should see a nice warm up. Get more details in the extended forecast here.
