Thornton’s March 2024 preview: Temps warm considerably but snow is often abundant

The month of March in Denver is usually one that is welcomed heartily by residents. We begin to shake off the cold of winter with warmer temperatures and calmer conditions. That does not mean we are done with snow and cold by any means.

March usually offers healthy snowfall giving us an opportunity to add to our seasonal totals.  While there is good snow potential in March, the month also typically brings much warmer temperatures.

March is historically Denver’s snowiest month and brings about 20% of our annual snowfall.  Heavy, wet spring snow storms can oftentimes bring the entire month’s snowfall total in one monstrous snow.

We also start the transition to spring and severe weather season and the month typically brings our first thunderstorms of the year.  Temperatures climb throughout the month and by the end our average daytime highs are near 60 degrees.

February 2024 weather recap: Much warmer and wetter than normal

The past month was one that started out with some excitement in the form of snow (after rain) but then became far calmer and warmer.

On the third of the month, we saw a system move in that initially offered precipitation in the form of rain, and a good bit of it. That eventually transitioned to snow giving us 3.2 inches. Our biggest snowfall of the month of 4.2 inches followed on the 10th. We then saw a few other, smaller snowfalls, enough to put the month above average in terms of snowfall and precipitation.

Temperatures never really got all that cold. There was only one single digit reading for the month, less than you would expect and, particularly toward the latter part of the month, spring-like mercury readings were pretty common.

Thornton’s average temperature for the month came in at 38.5 degrees. That was far above our 18 year running average for February of 31.8 degrees. That put February 2024 into the books in a tie with February 2016 for the second warmest February. Number one is February 2017 at 40.1.

Out at Denver International Airport where the Mile High City’s official measurements are taken, the month saw an average temperature of 37.6 degrees. That too was well above their long term average for February of 32.7 degrees.

Temperatures in Thornton ranged from a high of 68.6 degrees on the 20th down to a low of 8.9 degrees on the 17th. Denver twice saw its warmest reading of 65 degrees and its coldest reading was 7 degrees.

Precipitation was bountiful, not only due to some decent snow but mainly due to the rain on the third. Thornton saw 1.67 inches of liquid precipitation for the month, a full inch above the 18 year February average of 0.67 inches.

Denver was drier, but not by a lot. The airport recorded 1.46 inches of liquid precipitation. This versus the Mile High City’s long term February average of 0.41 inches.

In terms of snowfall, we lacked any big storms but the littler ones added up. Thornton recorded 11.8 inches of the white stuff, just above the 18 year running average of 11.6 inches.

Denver bested us on the snowfall front recording 13.7 inches, well above their long term February average of 5.7 inches.

Overall mild temps for Thornton’s weekend but with wind and a chance for precipitation

Spring-like temperatures certainly sound like a great way to kick off the month of March. However, winds and elevated fire danger are going to dampen the enthusiasm.

Friday looks to be the most pleasant day, relatively speaking. We will see highs in the mid-60s under mostly sunny skies. Winds will be breezy throughout the day. Tonight, winds ease and skies will be mostly clear. Overnight lows will dip to the mid-30s.

Saturday looks to be the warmest day of the period – but also the windiest. Sunny to mostly sunny skies will be above with highs in the mid-60s. Wind speeds will ramp up, particularly in the afternoon, when gusts could hit 40+ mph. The fire danger will be increasing and it would not be surprising to see a Red Flag Warning issued. Saturday night, cloud cover will increase as a front approaches. Lows will dip to the mid-30s and there is a slight chance to see some rain / snow after midnight.

Sunday, some snow will be possible in the morning. Accumulations look to be minimal, if at all, but there is an outside chance we see a more powerful band move through like we did earlier this week. The afternoon brings just a slight chance for a rain shower. Highs will reach the low to mid-50s under partly clear skies.

Have a great weekend!

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.

Internet down February 29, real-time data currently unavailable – FIXED

Update, 7:30am – We are back up and running! Whew!

Unfortunately, the Internet connection that allows the updating of the website with real-time data from our weather station is currently down. We have no ETA at this time as to when it will return to operation.

Much of our website, other than the real-time data, remains fully functional. This includes the forecasts, watches / warnings and more.

We apologize for the inconvenience.

Wednesday in Thornton starts with a chill, will warm up nicely

In the wake of yesterday’s cold front, we do begin the day with some cold temperatures. A nice recovery will be in store, however, but also with some breezy winds.

Sunny skies start us off and will be with us throughout the day. We will be dry but some breezy winds from the south will be seen. High temperatures will top out right near the 50 degree mark.

Tonight, lows will dip to the mid to upper 20s under mostly clear skies.

Tuesday in Thornton chills out, offers up some light snow

The cold front is working its way south, a bit delayed, but still on its way. With its arrival around 7:00am, a much cooler day than recent ones is on tap.

Mostly cloudy to cloudy skies will be above for most of the day. We have actually already seen our high for the day with temperatures cooling a few degrees as the front arrives. Daytime highs will be in the mid-30s.

We begin to see chances for precipitation around 8:00am and then continuing into the late afternoon / evening. There isn’t much to work with here so don’t expect much – maybe a half inch, an inch if we are lucky.

Tonight, skies will clear after dark and we will dry out. Overnight lows will drop to the teens.
