Typically November is a quiet weather month with plenty of nice, fall days but it can also turn wet with healthy doses of snow and moisture.  The wide variety of conditions can create picturesque scenes ranging from blue skies and snow-capped mountains to a wintry wonderland in the metro area.

November is the second snowiest month of the year so winter conditions are not unusual.  Typically though, these bouts of cold are short-lived and normal daytime conditions are pleasant.

Outdoor activities continue to be quite popular during the month.  The cooling temperatures do oftentimes lead to an increase in wildlife activity.

Wednesday sees a return of dry conditions, seasonal temperatures

Wednesday, November 25th, 2020 5:08am MDT

In the wake of our recent snow storm, we bounce right back in typical Colorado fashion. Today will offer plenty of sun and temperatures returning to near normal.

Sunny skies will be with us this morning then the afternoon brings a few clouds but nothing intrusive. Overall conditions will be calm and dry. Highs today should top out near the 50 degree mark however given the fresh snow cover, it wouldn’t be surprising to fall short.

Tonight, skies will be mostly clear with overnight lows in the mid-20s.

We’ll have a complete Thanksgiving weekend forecast later today but, as a preview, you can expect generally cooler temperatures but dry conditions.

Fast hitting snowstorm starts off Thornton’s Tuesday, sun returns by the end of the day

Tuesday, November 24th, 2020 5:11am MDT

Mother Nature delivering a bit of a wallop this morning, a stronger one than anticipated. The heavy, wet snow will continue until mid-morning making for a rough commute but then the sun will return.

Cloudy skies will be above until about 10:00am and then they will start to break with mostly sunny skies for the afternoon. The snow will continue until mid-morning, adding to our 2.3 inch total we measured at 4:00am. Total accumulations should end up in the 3 to 5 inch range.

A Winter Weather Advisory is in effect until noon as the snow has quickly covered roads creating hazardous driving conditions. Allow plenty of time for your morning commute. Highs today will top out near the 40 degree mark.

Tonight, skies will be clear and overnight lows will drop to the low 20s.

Thornton’s workweek starts out relatively mild, cold and possibly snow arrive tonight

Monday, November 23rd, 2020 5:00am MDT

A short workweek as we head into Thanksgiving and the weather will be seeing some ups and downs. Today will be the warmest day of the week but tonight a weak system will have the potential to bring rain and snow.

Mostly sunny skies will be above today with light winds out of the west. Highs will top out in the mid to upper 50s, a good bit above the average high for the date of 49 degrees. Clouds will be increasing by sunset, becoming cloudy after midnight.

We may see some light rain this evening after 5:00pm. Precipitation should change to snow in the early morning hours tomorrow. Overnight lows will drop to around 30 degrees.

The coming system isn’t particularly well organized and models are not in agreement on its track and impact. There is the potential for us to see an inch or two of the white stuff from about 2:00am to 11:00am tomorrow.

This Week in Denver Weather History

This time period in November has been exceedingly eventful throughout Denver weather history.  Notable as usual are big wind events that have caused damage and injuries.  Snow of course is also quite present, including the Thanksgiving blizzard of 1983 which dumped an astounding 21.5 inches of snow on the Mile High City.

From the National Weather Service:

21-22

Sunny to mostly sunny skies are going to above throughout the day. Winds will be relatively light, conditions dry. Highs will top out in the mid-60s, well above the average high of 50 degrees for the date.

Tonight, lows will dip to near freezing under partly clear skies.
