Cool temperatures, some showers for Wednesday in Thornton

Wednesday, July 5th, 2023 4:57am MDT

Following yesterday’s downpour, today will be much less dramatic. It will, however, be much cooler and we will see some showers.

With the passing of yesterday’s cold front, we will see highs only in the mid-60s today. Skies will be cloudy this morning, perhaps a slight breakup in the coverage in the afternoon.

Some showers will be possible throughout the day with some thunder in the afternoon. Most of the drama should remain to our south so, at this time, we expect only light showers.

Tonight, skies remain mostly cloudy. Shower activity will be possible, mainly before midnight. Overnight lows will be in the mid-50s.

Mother Nature threatens with her own style of fireworks for the 4th of July in Thornton

Tuesday, July 4th, 2023 4:47am MDT

You may not get the fireworks you were hoping for today. Thunderstorms are set to arrive this afternoon and evening, potentially putting a damper on any Independence Day celebrations.

We start out nice enough with cool temperatures and partly sunny skies. High temperatures will top out in the low 80s.

This afternoon, cloud cover will increase and so too will the chance for storms. These may come in two rounds with one in the afternoon, then another in the evening right about prime fireworks time. If you have outdoor activities scheduled, you will certainly want to be prepared to move inside. Some of these storms will have the potential to deliver large hail, heavy rain and strong winds.

Tonight, thunderstorm chances will ease after midnight. Skies will remain mostly cloudy to cloudy with lows in the low 50s.

July 2 to July 8: This week in Denver weather history

Sunday, July 2nd, 2023 1:13pm MDT

This Week in Denver Weather History

In our July weather preview we discussed how the month is not only Denver’s hottest but also its stormiest. Our look back at this week in Denver weather history helps to illustrate that fact. We start seeing 100+ degree days as well as many of the types of fast moving thunderstorm events expected this time of year.

From the National Weather Service:

29-2

In 1990…almost a year to date after the record breaking heat in early July 1989…the third longest heat wave in Denver history started. From June 29th through July 2nd the temperature reached 100 degrees or more on four consecutive days. The highest reading of 102 degrees occurred on the 29th…30th…and 1st. Combined with the 102 degree reading on June 27th this would have been the longest heat wave on record…but the temperature climbed to only 98 degrees on June 28th.

29-15

In 2000…the 29th marked the beginning of a near record hot streak for metro Denver. The high temperatures…as recorded at Denver International Airport…exceeded the 90 degree mark for 17 consecutive days from June 29th through July 15th. The record of 24 consecutive 90 degree or above days was set from July 13th through August 5th…2008.

1-18

In 1874…a streak of 18 consecutive days of 90 degrees tied for second with another streak that was later set in the summer of 1901. The record of 24 consecutive days was established in the summer of 2008.

1-31

In 2012…it was the hottest July on record in Denver since weather records began in 1872. The average temperature for the month was 78.9 degrees which was 4.7 degrees above normal. There were 27 days in which the high temperature equaled or exceeded 90 degrees…which established a new record. There were also 7 days in which the temperature equaled or exceeded 100 degrees which tied the record set in 2005.

In 1879…a severe hail storm produced considerable damage in the vicinity of Arvada. Some of the stones were unusually large…measuring 6.5 inches in circumference (2 inches in diameter) with an average weight of 1 ounce. The stones were uniformly large with one side concave. The greatest damage was to early wheat…cabbage…and vines. A tree just to the south of the weather station in downtown Denver was struck by lightning. Residents in the house 15 feet away were affected by the strike.

Thornton’s weekend will start out damp but then dries out and warms up

Friday, June 30th, 2023 4:55am MDT

Heading into the weekend we do have one day with cooler temps and a bit of rain on tap. After that, however, conditions will improve and be quite pleasant.

For today, partly sunny to mostly cloudy skies will be above. High temps will top out in the low to mid-70s. Showers will be possibly from late morning through the evening with the best chance coming in the afternoon. The atmosphere looks to be more stable today so we do not expect the drama we saw yesterday. Tonight, skies will begin to clear and any showers will end soon after dark. Lows will be in the low 50s.

Saturday looks to be a downright pleasant day. Look for sunny skies to be above with temperatures topping out in the 80s. We will be dry and calm. Saturday night, lows dip to the mid-50s under mostly clear skies.

Sunday will be the warmest day of the period with highs in the mid to upper 80s. Skies will be clear in the morning then there will be some clouds in the afternoon. A slight chance for a thunderstorm is possible Sunday afternoon. Have a great weekend!

Thursday in Thornton to cool down a bit, offer a good chance for thunderstorms

Thursday, June 29th, 2023 4:51am MDT

Following a string of very mild, dry days, we now get a break. Temps will be below normal today and we expect to see PM thunderstorms, some possibly severe.

The day starts out with a good bit of cloud cover above, even a sprinkle or two of rain. We will then see some clearing and it will be dry for most of the morning. High temperatures will top out in the mid to upper 70s. The afternoon will see thunderstorms begin to develop, mainly after 2:00pm.

This evening, storm activity will actually increase, possibly turning severe with good-sized hail being a concern. Storm activity will continue to be possible for the first half of the night, then largely settle down after midnight although there may be some lingering activity. Lows will be in the mid-50s.

Quiet, dry weather for Thornton’s weekend but with a bit of wind

Friday, June 23rd, 2023 5:01am MDT

A break from the storms that have dominated much of this week. The weekend will see temps near normal and dry conditions but with some breezy winds.

For today, we start out with some lingering cloud cover but skies will clear by mid to late morning. High temperatures will top out in the mid-80s. Winds will become breezy this afternoon through the first half of tonight. Lows tonight will be in the low 50s.

Saturday sees clear skies with nary a cloud to be found. Highs again will reach the mid-80s. There will, unfortunately, be breezy winds throughout the daytime hours. Saturday night, breezy winds will continue with mostly clear skies. Lows will be in the low 50s.

Sunday looks much like the other days but a bit cooler. Look for highs in the low 80s under sunny skies. Winds will be breezy in the afternoon and evening.

Have a great weekend!

Thursday to offer cooler temps, another round of thunderstorms

Thursday, June 22nd, 2023 5:05am MDT

Following yesterday’s thunderstorms, we cool down today. Moisture remains abundant though and another round of storms is expected.

Partly sunny skies start us off and will be with us through the morning. Conditions will initially be calm with highs topping out in the mid-70s.

Thunderstorms will again develop after noon. Best chances come from about 3:00pm to 9:00pm. Some of these storms will again have the potential to turn severe with large hail, damaging wind and brief, heavy rain. How strong the storms get will depend on how much daytime heating we receive to get things brewing.

Tonight, storms will begin to taper off after 9:00pm but some activity may potentially be seen throughout the night just like last night. Lows will be in the mid-50s.
