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.

All of the above help lead to a month in which a wide variety of scenes, flora and fauna can be captured.

Wednesday remains a bit chilly but with less wind

Wednesday, November 30th, 2016 5:06am MDT

Weather conditions today become a bit more stable. Temperatures will remain below normal however we will enjoy a break from the wind.

We start out the day with mostly clear skies and that should continue throughout the day. Temperatures start out very cold but then will gradually warm toward a high in the low 40s. Average for the date is 46 degrees.

Looking ahead, we’ll be seeing a bit of a roller coaster over the next week or so as a series of systems impact us. We’ll be dry tomorrow but with more clouds and slightly cooler temps as the next weather-maker approaches. Friday will see much colder conditions with perhaps a shot of light snow.

We then warm back up a bit for the weekend and Monday before our next system comes through late Monday into Tuesday. Models are pointing to that system bringing the coldest readings of the season so far. Unfortunately we are not convinced there will be a lot of snow with it.

In the meantime, enjoy the calm, clear conditions today.

Chilly temperatures, breezy winds for Thornton’s Tuesday

Tuesday, November 29th, 2016 5:16am MDT

A diving jet stream will be pulling cooler air from the north today bringing cooler temperatures to the air. That will be coupled with wind caused by a strong pressure gradient making for what won’t be an overly pleasant day.

We start out the day with partly clear skies but will then see an increase in coverage with mostly cloudy skies for the balance. Temperatures today will start out quite chilly and below freezing then work toward a high of around 40 degrees.

The main weather feature will be the aforementioned wind. Speeds will increase this morning and by about noon be topping out with gusts to 30mph. Coupled with the chilly temperatures, it will be a bit uncomfortable outdoors.

Thornton’s workweek starts seasonal, then turns colder

Monday, November 28th, 2016 5:03am MDT

Earlier in the month many were wanting an end to unseasonably warm weather. That certainly has happened and while today will be a typical day for this time of year, the rest of the week will see things cool considerably.

For today we will see partly sunny skies above throughout the day. Temperatures will be warming to a high in the mid-40s, right near the average for the date of 46 degrees. Winds will be lighter today than yesterday, just a bit breezy in the afternoon.

The next system will be moving through later today and that is going to bring colder temperatures and another healthy shot of wind on Tuesday. From there, a series of reinforcing cold fronts will drive high temperatures downward at least through Friday. One system late Thursday into Friday may bring a quick shot of snow but right now it doesn’t look like it will amount to much.

More details in the extended forecast.

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.

Weekend to start warm, end a bit cooler with a chance for showers

Friday, November 25th, 2016 4:52am MDT

Two out of the three days ahead look to be very pleasant and mild. The third, Sunday, will see things cool down and bring just a slight chance for showers.

For Black Friday, shoppers are enjoying calm but also very chilly conditions to start things off. We will however be warming up nicely with highs in the upper 50s under sunny skies.

Saturday continues the warm weather, perhaps with a couple of clouds in there. Temperatures should top out right near the 60 degree mark.

On Sunday a system is expected to move through right around mid-day and that will mix things up a bit. Temperatures will reach the mid-50s but with some breezy winds as the front pushes through. Sunday afternoon may bring a light rain shower but that is far from certain as there isn’t expected to be much moisture at the lower levels.

More in our extended weather outlook including a preview of what looks to be a chilly week next week.

Thornton’s Thanksgiving to offer up sun and seasonal temps but also a healthy dose of wind

Thursday, November 24th, 2016 3:42am MDT

A bit of a mixed bag when you look at the weather conditions for today. On one had temperatures will be topping out right near normal with plenty of sun. On the other, wind is going to make it less than pleasant for much of the day.

We start out with mostly sunny skies and then will have only a few clouds from mid-morning through the rest of the day. With the arrival of the downslope wind pre-dawn, temperatures jumped a bit right off the bat and gave a head start toward our high of around 49 degrees.

Look for those winds to increase in speed and from about 8:00am through 1:00pm we will be seeing gusts in excess of 30mph. After 2:00pm it should start to settle down. Overnight tonight we will see the mercury drop considerably with lows in the mid-teens. The balance of the long weekend should be warmer and calmer.

We wish you and yours a very happy and blessed Thanksgiving and thank you for your support over the past year!

Thornton to enjoy a seasonal, calm Wednesday

Wednesday, November 23rd, 2016 5:26am MDT

We are starting out the morning on the chilly side for sure. However, we will be warming up nicely with a good bit of sun above and temperatures right near normal.

Sunny skies start things off then we will see a few clouds but not enough to put a damper on the day. Temperatures will be warming to a high near the 50 degree mark, close to the 49 degree average for the date. Conditions will be calm and dry.

Looking ahead, Thanksgiving Day is going to be similar to today but with a bit more sun and some breezy winds. Friday and Saturday warm up to the mid to upper 50s with calm, dry conditions. After that, it appears next week is going to be a bit unsettled and colder as a series of systems move through.

Cool, damp weather for Thornton’s Tuesday

Tuesday, November 22nd, 2016 5:07am MDT

Not much but we are at least receiving a little bit of precipitation. Coupled with the moisture, we will be much cooler today and have some breezy winds.

We start out the day with cloudy skies and slight showers although most of the activity is just to our east. Right now it looks like it will be tough for those to transition to snow but it is possible. Look for the precipitation to start tapering off by about 8:00am, coming to an end in the early afternoon.

We will see an increase in wind speeds this morning with breezy winds lasting through the day. By mid to late afternoon some sun should start peeking out. Temperatures today will be topping off in the mid to upper 40s, right below or close to normal.

Keep an eye on the shower activity with our interactive radar here.

Thornton’s workweek starts warm with chance for showers

Monday, November 21st, 2016 4:58am MDT

We will enjoy a mild day today but also with a healthy bit of cloud cover. Later today a system will arrive bringing a chance for rain showers and possibly some light snow into tomorrow morning.

Look for mostly cloudy skies to be above throughout the day today. Winds start out coming out of the south but then will shift north as a system arrives in the afternoon. Temperatures will be climbing to a very comfortable range in the low to mid-60s.

The afternoon may bring a sprinkle of rain with some better chances in the evening. From about 11:00pm into tomorrow morning we will have better opportunities, perhaps with some light snow mixed in during the early morning hours. We are not expecting much precipitation in either form at this time.

Have a great day!
