Warming temperatures, calm weather conditions to highlight Thornton’s weekend

Friday, February 16th, 2018 5:27am MST

Following a quick dusting of snow last night and a chilly start this morning, we are going to see much nicer conditions for the three day period. Today will be largely seasonal but temps will be improving through the weekend and be quite mild by Sunday.

For today, look for temperatures to be a bit slow in their ramp up but we should see highs reach the low to mid-40s. Mostly sunny skies will be above, conditions calm. Tonight, skies remain mostly clear but we do expect some gusty winds. Overnight lows into Saturday morning will bottom out in the mid-20s.

Plenty of sun and pleasant conditions lie ahead for tomorrow. Look for mostly sunny skies throughout the day with highs in the mid-50s. Saturday night into Sunday morning, skies will be mostly clear with lows dropping to a bit below freezing.

The weekend closes out with the warmest day of the period. Highs Sunday will reach into the 60s although we will have a bit more cloud cover.

Get out and enjoy that warm weather! Presidents Day is going to see a cold front arrive that will bring colder temperatures and perhaps snow. Get more details on that in our extended forecast here.

February signifies the start of the climb toward warmer temperatures for the year.  Cold and snow though do intrude but, coupled with milder conditions, there are lots of photo opportunities as can be seen in our monthly slideshow.

The month is one of our least snowiest of the year but it isn’t unusual to see the landscape blanketed in white.  Warming temperatures through the month can bring the onset of spring fever and gives residents the opportunity to enjoy some prolonged time outdoors on the mild days.

Cold or mild, snowy or dry, our scenery is almost always gorgeous – and photo worthy.

This week in Denver weather history

February 11 to February 17: This Week in Denver Weather History

Denver’s weather is often a story of extremes and even in what is historically a calm period like February, significant events can and do occur. From record-setting Arctic cold that sent temperatures to far below zero to powerful, damaging wind, this week in Denver weather history has been an eventful one.

From the National Weather Service:

31-12

In 1899…a protracted cold spell lasted almost two weeks. Low temperatures plunged below zero on all days but February 9th with a reading of 6 degrees. The coldest low temperature of 22 degrees below zero on February 6th was a record low for the date. Low temperatures of 20 degrees below zero occurred on both February 11th and 12th… But only the 11th remains as the record minimum for the date. High temperature of only 5 degrees below zero on February 11th was a record low maximum for the date. High temperatures climbed to only zero degrees on both February 2nd and 3rd…but were not records. Intermittent light snow or flurries fell during the period. The most snowfall…2.0 inches…occurred on February 2nd.

5-11

In 1978…the 5th marked the start of a record 7 consecutive days of dense fog at Stapleton International Airport. The heavy fog reduced the visibility to 1/4 mile or less for a period of time on each of these days. Light snow and/or freezing drizzle occurred on most days. Fog reducing visibility to less than 7 miles was recorded at Stapleton International Airport on 11 consecutive days through the 15th. During the period 5-14…the cold thick fog deposited heavy rime ice up to 5 inches thick on power lines and poles over a wide area of eastern Colorado…causing a major electrical power outage disaster.

9-11

In 1965…heavy snowfall totaled 6.2 inches at Stapleton International Airport where northeast winds gusted to 25 mph.

In 1993…the same storm that dumped heavy snow in the mountains combined with an arctic cold front to produce heavy snow across metro Denver. Upslope snows of 4 to 8 inches were common with some areas receiving nearly a foot. Ten inches of new snow were measured in Parker and 7 inches in southeast Denver. At Stapleton International Airport… Snowfall totaled 8.1 inches. Strong winds combined with the snowfall to produce near-blizzard conditions over the plains closing many roads east of Denver. North winds gusted to only 18 mph at Stapleton International Airport on the 9th.

10-11

In 1971…a wind gust to 80 mph was recorded in Boulder at the National Center for Atmospheric Research. A wind gust to 69 mph was measured at the National Bureau of Standards. In downtown Boulder wind gusts to 43 mph were clocked. No damage was reported. North to northwest winds gusted to 39 mph on the 10th and to 41 mph on the 11th at Stapleton International Airport.

In 1999…heavy snow developed over sections of metro Denver during the evening hours. Snowfall totals included: 6 inches at Eaglecrest…6.5 inches at Highlands Ranch…and 8.5 inches about 5 miles south of Sedalia. Only 1.0 inch of snow fell at the site of the former Stapleton International Airport. Strong winds and snow caused near blizzard conditions north of metro Denver.

10-12

In 1958…heavy snow fell across metro Denver. At Stapleton Airport…where northeast winds gusted to 22 mph…6.7 inches of snowfall were measured.

In 1995…cold arctic air brought heavy snow to the foothills and western Denver suburbs. Golden measured 15 inches of snow with 14 inches in south Boulder. Locations in the foothills recorded between 10 and 15 inches of snow. Only 6.1 inches of snow fell at Stapleton International Airport where north winds gusted to 30 mph on the 10th.

10-13

In 1905…an extremely cold arctic air mass moved over the city behind a cold front on the 10th and persisted through the morning of the 13th. North winds were sustained to 25 mph behind the front on the 10th dropping the temperature to a low of 2 degrees below zero…which was also the high reading on the 11th. Light snowfall totaled 3.0 inches overnight of the 10th into the 11th. The low temperature plunged to 19 degrees below zero on the 11th. Records were set on the 12th and 13th. The high temperature of only zero degrees on the 12th was a record low maximum for the date. The low readings of 21 degrees below zero on the 12th and 14 degrees below zero on the 13th were record minimum temperatures for those dates.

In 1875…northwest winds were brisk all day. The velocities increased to 30 to 50 mph during the early evening.

In 1957…Chinook winds gusting to 49 mph warmed the temperature to a high of 64 degrees at Stapleton Airport.

In 1971…a rare February thunderstorm produced 1/4 inch diameter hail in southwest Denver.

In 1981…the cold spell of the 10th came to a quick end with strong Chinook winds. Gusts to 84 mph were recorded at mines peak and to 80 mph at Wondervu. Gusts in the foothills ranged from 50 to 65 mph. Southwest winds gusted to only 23 mph at Stapleton International Airport.

In 1988…wind gusts to 77 mph were measured at Echo Lake. West winds gusted to only 32 mph at Stapleton International Airport.

In 1900…northwest winds sustained to 52 mph with gusts to 60 mph warmed the temperature to a high of 58 degrees on the 11th. An apparent cold front overnight produced 3.7 inches of snow and northeast winds gusting to 30 mph. The high temperature on the 12th was only 26 degrees.

Cold front to bring changes in the weather to Thornton on Thursday

Thursday, February 15th, 2018 5:11am MST

A bit of half and half today. The day starts out nice enough and will actually see high temps around normal. However, an approaching cold front will send the mercury down in the afternoon and offer up a slight chance for snow.

Mostly sunny skies will be above initially then a slow increase in cloud cover will occur as the front approaches. By this evening it will be mostly cloudy. Winds will be light initially then become a bit breezy by late morning and last into the evening with the front pushing through.

Temperatures will warm up nicely with us hitting our daytime high in the mid to upper 40s around noon or so. By about 3:00pm, the cold front will make itself felt in earnest and temperatures will decrease somewhat quickly.

After 3:00pm and the until about 10:00pm we do see slight chances for a bit of snow. Most of the moisture will be south of us though so a half inch is the best we could hope for and likely will be less.

Skies will clear overnight and low temperatures overnight will hit the mid-teens.

Unseasonably warm temperatures Wednesday to be driven by downslope winds

Wednesday, February 14th, 2018 5:08am MST

Some good, some not so good in today’s weather forecast for Thornton. While we will enjoy temperatures well above normal, we will also see a good bit of wind from the west.

Mostly sunny skies start things off and we will see a bit of an increase in coverage by about noon but still expect some blue up there. Temperatures start out chilly but then will see a steady increase with highs to the low to mid-60s.

Downslope winds are going to be the reason for those warm temperatures. Speeds will increase this morning, peaking in the afternoon. At their height, gusts could push toward 40mph.

Tonight, winds will ease gradually with overnight lows near the freezing mark.

Keep an eye on the temps and wind here.

Thornton’s Tuesday to offer warmer temperatures, more sun

Tuesday, February 13th, 2018 5:14am MST

Yesterday’s chill is set to move out and in its wake we will enjoy a pretty nice day today. Expect temperatures to be not too far off of normal for the date and a decent bit of sun.

The day starts with mostly sunny skies and we should have the same sky conditions for much of the day, perhaps a bit fewer clouds in the evening. Temperatures will start out on the chilly side but then warm up nicely with highs topping out in the mid to upper 40s.

Tonight, skies remain mostly clear with lows in the upper 20s.

All in all it should be a pretty nice winter day.

Cold front keeps things chilly for Monday, might offer some flurries

Monday, February 12th, 2018 5:03am MST

A cold front has arrived this morning and that is going to chill us out again. While temperatures will be cold, we aren’t expecting much in the way of precipitation though.

The day starts with mostly cloudy skies and we can expect similar sky conditions throughout the day. The mercury is going to remain below freezing with highs today only in the mid to upper 20s. Some light snow / flurries will be possible this morning into the first part of tonight. However, there isn’t much moisture to work with so little, if any, accumulation is expected.

Tonight, skies will begin to clear and any snow should be done by about 10:00pm. Lows tonight will dip into the teens.

Previewing the balance of the week, it looks to be a bit of a roller coaster. After today’s chill, Tuesday and Wednesday will warm up nicely followed by our next chance for snow Thursday. We then should see drying, warming conditions for Friday and the weekend. Get more details in the extended weather forecast here.

Cold front to bring unsettled weather for start of Thornton’s weekend

Friday, February 9th, 2018 5:03am MST

Quite a bit of a change in our weather. A cold front moved through last night and that will offer up much colder temps and bring chances for precipitation today and Saturday.

For today, areas of dense fog start things of and a few spots of freezing drizzle may be seen in the morning. The bulk of the daytime should remain dry then this evening some drizzle and a few flakes of snow may be seen. Temperatures today will be chilly with highs in the mid-30s under mostly cloudy skies.

Overnight tonight we may see some freezing drizzle, a bit of snow but with little accumulation. Temperatures are going to get quite cold with lows down well into the teens.

Saturday is when we expect moisture to increase and give us our best chance for snow. The best opportunity comes tomorrow afternoon with things ending in the late evening. Overall, we could see a couple of inches of the white stuff. Highs tomorrow will only be in the low to mid-20s with cloudy skies.

As the system moves out Saturday night, skies will begin to clear and that will lead to very cold temps. Lows into Sunday morning are expected to hit the single digits.

The good news is that Sunday sees things start to turn around. There will be plenty of sun and temperatures should rebound nicely to around the 40 degree mark.

Stay safe, stay warm!

Temperatures to climb Thursday but so will the wind speeds

Thursday, February 8th, 2018 5:10am MST

A bit of good and bad with our weather today. We will enjoy our mildest day of the week with temps pushing close to 20 degrees above normal. However, much of that warmth will be the result of some pretty strong, downslope winds that we will be experiencing.

The day starts out mostly sunny and similar sky conditions should be above throughout the day. We start out a bit chilly but not as cold as usual thus giving us a head start toward our high temperature today in the low to mid-60s.

Winds will be a bit breezy initially this morning then increase in speed as the day progresses, peaking around 3:00pm with gusts to 35mph or so before gradually easing in the evening and the first part of tonight.

Tonight, partly clear skies will be above with lows dipping to the mid to upper 20s.

The wind won’t make it easy but enjoy that warmth today if you can as things will be turning colder, particularly tomorrow and Saturday. Have a look at the extended weather forecast here.

Mild temperatures and a good bit of sun on Wednesday

Wednesday, February 7th, 2018 5:10am MST

Thornton is set to enjoy a pretty nice day today. The mercury will rise a good bit higher than normal and other than a touch of wind, it will be a pleasant one.

The day starts off with some fog in a few places but that won’t last long. Once gone, we will be left with mostly sunny skies until the late afternoon when a few more clouds will build.

Some breezy winds will arrive this afternoon but nothing overly strong. Aided by the downslope winds, temperatures will top out in the mid-50s.

Overnight tonight, look for partly cloudy skies above with lows dipping to around 30 degrees.
