Wintry weather stages a return for Thornton’s Thursday

Thursday, April 2nd, 2020 5:05am MDT

Hopefully you enjoyed the warm weather of recent days because today brings a significant change. Temperatures will be quite chilly and following some rain, we will see snow make an appearance.

Cloudy skies will be above throughout the day. Winds will be a bit breezy, particularly in the late afternoon. High temperatures today will only reach a couple of degrees above freezing. Light rain and drizzle will be seen this morning then this afternoon we begin a transition to snow.

A second reinforcing cold front will push through dropping temperatures in the late afternoon. Snow will then increase. Most snow activity will come from about 4:00pm to 10:00pm. We may see total accumulations, mainly on grassy areas, of an inch or two.

Tonight, a few flurries may fall throughout the night. Overnight lows will be quite cold and drop into the teens.

April arrives with mild temperatures but colder, wetter weather awaits

Wednesday, April 1st, 2020 4:52am MDT

Thornton begins the month with a very nice day and temperatures well above normal. It is no April Fool’s joke though that snow is set to return in less than 36 hours.

Today starts out with clear skies then we see clouds build up a bit later this morning. We will still have mostly sunny skies overall and they shouldn’t do much to inhibit temperatures. Highs today will push toward the 70 mark.

A cold front will be pushing through tonight and that will lead to increased cloud cover and perhaps a few drops of rain after 9:00pm. Overnight lows tonight will be near freezing.

Looking further ahead, Thursday starts out dry but temperatures will be chilly. The PM will bring some rain and snow and some minor accumulations will be possible tomorrow night. Until then, enjoy the warmth!

The month of March is the start of meteorological spring and while conditions do begin warming, winter weather is certainly out of the question.  From hot to cold, snow to rain, the conditions can be very conducive to great pictures as we see in our slideshow.

March in Denver typically means frequent and rapid weather changes. The days grow longer and we start enjoying more sunshine and sometimes summer-like weather. However, on occasion arctic air masses can still force their way south into Colorado dropping temperatures quickly and markedly.

With the active wildlife, increased outdoor activities by us humans, and of course the weather, March imagery contains a wide variety of subjects and extremes.

  • Slideshow updated March 31, 2020. To learn more about how to send your photo to us for inclusion in the slideshow, see below the slideshow.

Thornton’s weekend weather starts out unsettled, will end calmer and seasonal

Friday, March 27th, 2020 4:59am MDT

A bit of a mixed bag of weather for us over the three day period. We start out with chilly temps and a bit of winter-like precipitation but then things will dry out and warm up.

For today, fog greets us early and then cloudy skies will be above for the rest of the day. Some light rain / freezing drizzle will be possible early then light rain this afternoon. Highs will only be in the low 40s. As temperatures drop late this afternoon and evening, precipitation will change over to snow and continue till midnight before tapering off.

Accumulations of an inch or so are possible, maybe more depending on when the switch to snow occurs. Overnight lows tonight will be just below freezing.

Saturday will be dry but cool with highs topping out around the 50 degree mark. Breezy winds will be the most notable feature and will persist through the day and into the evening. Saturday night, partly cloudy skies will be above with lows in the mid to upper 20s.

Sunday looks to be the most pleasant of the period. Mostly sunny skies will be above with highs in the mid to upper 50s. Have a great weekend and stay safe!
