Sun and seasonal temperatures Thursday but wind looks to blow.

Thursday, May 7th, 2020 5:12am MST

Thornton’s weather today will start out nice enough with comfortable temperatures and sunny skies. However, winds will be increasing making it less than pleasant and fire danger will be increasing.

The day starts with sunny skies then perhaps a few clouds later in the day but still plenty of blue above. High temperatures today will top out right near the average high for the date of 69 degrees.

The big story is going to be the wind. It will become breezy by mid-morning then winds get cranking in the afternoon. Gusts to 40+ mph will be possible at their height. Winds will east after dark but remain quite breezy until after midnight.

The wind coupled with low humidity and dry fuels has prompted a Red Flag Warning that will be in effect from 11:00am to 8:00pm. Please exercise appropriate caution as fire danger will be high.

Tonight, partly cloudy skies will be above and lows will dip down to near freezing. If you have sensitive vegetation, you might want to be prepared to cover it.

Thornton’s May weather preview: Snow to severe weather all a possibility

Tuesday, May 5th, 2020 4:14pm MST
Thornton, Colorado May 2013 weather preview.

Thornton, Colorado May 2013 weather preview.

Colorado’s famously highly variable weather seems to showcase itself during the month of May when a variety of weather conditions can be seen.

Winter-like temperatures and snow are possible as are mid-summer like temperatures or the more typical spring severe weather.

As the month starts out in 2020 we are going to enjoy unseasonably warm conditions along with some chances for thunderstorms. Long range forecasts portend an overall warmer than normal month with equal chances of below, at or above normal precipitation.

The month can certainly bring extremes.  Snow is not entirely uncommon during the month, oftentimes causing damage to newly bloomed trees.  More common however is severe weather, particularly in the latter half of the month.  Thunderstorms become more frequent and their associated hazards – lightning, wind, hail and tornadoes – are usual visitors.

For a complete look at what lies ahead for the month of May, check out our full preview here.

April can be a tricky month weather-wise with everything from mild temperatures to snow to severe weather being possible.  The good thing about that is that it provides plenty of chances for great photos!

April marks a transition between winter and summer for most of the country but for Denver it is especially true as we can see a stunning variety of weather.

The proverbial April showers are certainly a possibility for Denver. Snow? Tornadoes? Thunderstorms? You bet – all can happen!

Throw in our usual wildlife plus the wide variety of birds that return to the Centennial State for the spring and summer and there is a lot going on.

Our monthly photo slideshow is going to feature images that we have taken but more importantly images that you have captured.  The photos can be of anything even remotely weather-related.

Landscapes, current conditions, wildlife, pets, kids.  Whimsical, newsy, artsy.  Taken at the zoo, some other area attraction, a local park, a national park or your backyard.  You name it, we want to see and share it!

Images can be taken in Thornton, Denver or anywhere across the extraordinary Centennial State.  We’ll even take some from out of state if we can tie it to Colorado somehow.

We’ll keep the criteria very open to interpretation with just about any image eligible to be shown in our slideshows.

What do you win for having your image in our slideshow?  We are just a ‘mom and pop’ outfit and make no money from our site so we really don’t have the means to provide prizes.  However you will have our undying gratitude and the satisfaction that your images are shared on the most popular website in Thornton.

To share you images with us and get them included in the slideshow just email them to us or share them with ThorntonWeather.com on any of the various social media outlets.  Links are provided below.

So come on, get those camera’s rolling!
