Denver sets record high temperature for November 26

Sunday, November 26th, 2017 6:31pm MST

Record High TemperaturesThe unusually warm temperatures we have seen this month definitely make it hard to believe we are now at the end of November. Today continued the trend as the mercury climbed into record-setting territory.

At 2:16pm the temperature topped out at 74 degrees at Denver’s official station at Denver International Airport.  These easily bested the record high temperature for the date of 72 degrees set in 1998.

Here in Thornton we were just a touch warmer with a high of 74.5 degrees.

The temperatures today continue the trend of a very warm, dry November.  Currently, the overall average temperature for the month is running nearly five degrees above normal.

Tomorrow looks to bring another unseasonably warm and possibly record setting day. See the extended forecast here.

This Week In Denver Weather History

November 26 to December 2: This Week in Denver Weather History

Cold, snow and wind are the dominant conditions we see in our look back at this week in Denver weather history. All three are common this time of year and extremes with those conditions seem to be unusually common as well.

Among the highlights are numerous high wind events that not only caused damage but also injury to unprepared residents. Significant snowfall also appears many times including a storm in 1983 that shut down the city for the Thanksgiving weekend and left snow on the ground for 63 days.

Friday, November 24th, 2017 5:12am MST

If you are heading out to brave the shopping crowds today, you won’t have any problems from Mother Nature. She has given us another day with temps well above normal although we will see some breezy winds.

The day starts under mostly sunny skies then by late morning into the afternoon a few more clouds arrive. We will see downslope winds out of the northwest that are breezy at times, particularly in the afternoon. Temperatures will be quite mild with highs in the mid to upper 60s.

Tonight, winds will ease and skies clear some. The mercury will dip to overnight lows in the mid-30s.

Potentially record-setting warmth for Thornton’s Thanksgiving

Thursday, November 23rd, 2017 6:12am MST

A very mild day ahead for our holiday. We will enjoy mostly sunny skies, calm and dry conditions and mercury readings that may set records.

The day starts with mostly sunny skies and those will stick with us until late afternoon when a few more clouds will arrive. Winds will be out of the west and relatively light until the overnight hours.

In terms of temperatures, we are expecting a high temperature this afternoon of 73 degrees. That is also the record high temperature for November 23rd set in 1915. Additionally, Denver’s warmest Thanksgiving Day (1909) saw a high reading of 73 degrees as well. It is quite possible those records will be tied or even fall. Much will depend on the impact of any cloud cover.

Tonight, winds will be a bit breezy under partly cloudy skies. Lows will dip to the low 40s.

We wish you a very happy Thanksgiving! You can keep an eye on current temperatures here.

Wednesday warms up with a good bit of cloud cover, some wind

Wednesday, November 22nd, 2017 5:05am MST

We are going to close out the workweek in pretty decent fashion today. Temperatures bounce right back to well above normal levels but we will see some clouds and some breezy winds.

The day starts off with partly sunny skies and we expect to see similar, high cloud cover throughout the day. Temperatures should top out in the mid-60s although those clouds may inhibit the forecast highs by a couple of degrees. Winds will be light initially then pick up a bit in the afternoon.

Tonight, skies will clear after midnight and overnight lows dip to the upper 30s.

Looking ahead to the Thanksgiving holiday, it looks to be a very mild one with plenty of sun and highs over 70 degrees. Details in the extended forecast.

Cold front to usher in cooler temperatures, slight chance for showers

Tuesday, November 21st, 2017 4:59am MST

A bit of a change Tuesday in the weather pattern of recent days. A cold front will be moving through that will offer up a slight chance for a few drops of rain and bring temperatures down close to normal.

The day starts off with some breezy winds and mostly cloudy skies. We will see a good bit of cloud cover until mid-morning when coverage will then begin to gradually ease. As the front pushes toward us early this morning, a few sprinkles of rain will be possible through the morning hours.

In terms of temperatures, it will remain cool this morning until the front passes then we should warm up some with highs today topping out right near the average high for the date of 49 degrees.

Tonight, partly cloudy skies will be above and lows dip to within a couple of degrees of freezing.

Looking ahead, unseasonably warm temperatures return for the balance of the week. Get a look at the extended forecast here.

The next big earthquake is due in the Pacific Northwest—but now scientists have pinpointed where along the coast a large earthquake is most likely to happen, according to a study published Monday. “We observed very compact sediments offshore of Washington and northern Oregon that could support earthquake rupture over a long distance and close to the trench, which increases both earthquake and tsunami hazards,” lead author of the study Shuoshuo Han,… » Click here to read the rest of Pacific Northwest May Be at Most Risk for the ‘Big One’
