Temperatures near normal, partly clear skies for Thornton’s Wednesday

Wednesday, December 4th, 2019 4:57am MDT

Today’s weather would best be described by the word “seasonal.” We’ll see temperatures near or perhaps just a bit above normal with calm conditions.

Partly clear skies start us off and will be with us all day. Winds will be light and not give us the benefit of downslope warming like they did yesterday. Highs today will be in the mid-40s.

Tonight, cloud cover will be increasing with lows in the mid to upper 20s.

Looking ahead, a weak system will cool things down tomorrow and offer a chance for snow and perhaps rain Thursday. More in the extended weather forecast here.

Thornton’s December weather preview: What will the arrival of winter bring?

Wednesday, December 4th, 2019 4:53am MDT

Thornton, Colorado's December Weather Preview

October and November brought Thornton cooler than normal temperatures and a good bit more snow than usual.  What will December hold for us?

The month of December brings with it the official start of winter and oftentimes, colder and snowier weather conditions.

It however can also offer unseasonably warm temperatures and bone dry conditions.  Given our recent mild and dry weather, we are certainly hoping for a change in the coming month.

Overall December’s monthly mean temperature of 30.0 degrees (1981 – 2010 averages) makes it our coldest month.  Snow is always on everyone’s mind this time of year but December is only our 3rd snowiest month behind March and November with an average of 8.5 inches of the white stuff.

Get all the details on Thornton’s December weather including a look back at historical events and a look at the long range forecast in our December weather preview here.

Tuesday’s weather to offer temperatures near normal, a good dose of sun

Tuesday, December 3rd, 2019 4:53am MDT

A pretty good looking late fall day ahead for Thornton. Downslope flow will help to overcome some of the radiational cooling of the snow cover and bring temps near normal.

A bit of a wave cloud starts us off but mostly sunny skies will be the general rule through the day. Downslope winds out of the west will provide some warming flow. Highs today will be in the mid to upper 40s.

Tonight, partly cloudy skies will be above with overnight lows near 20 degrees.

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.

Weekend weather in Thornton to offer a mixed bag of snow, wind and calm

Friday, November 29th, 2019 5:03am MDT

There is a little bit of everything in the three-day forecast. Today looks to offer up a bit of snow, tomorrow brings the wind and then we wrap things up with calm but chilly conditions Sunday.

For today, fog will be the biggest concern initially and a Dense Fog Advisory is in effect until 9:00am. After that, partly clear skies will be above. The afternoon will bring a chance for some rain / snow showers. At this time, minimal accumulations are expected however the system does show a good bit of instability so there is an outside chance for a fast inch or two. Highs today will only be around freezing. Tonight, skies will see some clearing with lows in the mid-20s. Wind speeds will be picking up after about 9:00pm.

Saturday brings the never-fun wind. The downslope flow will allow warming to the low 40s under partly sunny skies. However, wind speeds will be increasing with gusts to 40+ mph possible by noon. Saturday evening the winds will quickly ease. Overnight Saturday into Sunday, mostly clear skies will be above with overnight lows in the teens.

Sunday looks to be the calmest day of the weekend although it will be chilly. Sunny skies will be above with highs in the mid to upper 30s. Have a great weekend!

Temperatures today will be cold with a daytime high in the mid-20s expected. Winds will be blustery through noon then begin to taper off. This morning, wind chill temperatures in the low teens will be seen.

A Winter Storm Warning remains in effect until 2:00pm. Travel will be hazardous and is currently discouraged.

Thornton’s Monday starts off calm and seasonal, will be ending with a winter storm

Monday, November 25th, 2019 5:06am MDT

Hopefully you got out and enjoyed the mild weather this past weekend because big changes are on their way. The much-discussed winter storm will arrive this afternoon and deliver what will likely be our most significant snowfall of the season so far.

The day starts out with some sun above but cloud cover will steadily be increasing through the morning. Mostly cloudy skies early this afternoon will be entirely obscured by mid to late afternoon.

Temperatures will top out in the mid-40s by about noon but then it will be all downhill. Winds will be picking up by noon and continue to be blustery the rest of the day and overnight.

Some sprinkles of rain may be seen in the early afternoon and then things transition to snow after 2:00pm. Snow will be light and sporadic initially then picking up the pace after 5:00pm. Moderate to heavy snowfall will then continue tonight and into tomorrow morning. It should be easing up by about 9:00am tomorrow then only light snowfall is expected during the day tomorrow.

Total snow accumulations for Thornton should fall in the 6 to 12 inch range, perhaps even a bit more depending on intensity.

A Winter Storm Warning will be in effect from 8:00pm tonight to 5:00pm tomorrow. The snow and wind is going to create hazardous conditions and make travel difficult if not impossible at its worst.

You certainly should complete your preparations for the storm today working toward the possibility of being stuck in place tomorrow. Please be safe tonight and tomorrow! Get all the latest on our Winter Weather Briefing Page here.
