This Week In Denver Weather History

August 20 to August 26: This week in Denver weather history

Denver’s weather is not often boring. Lightning, hail, tornadoes and even swarms of grasshoppers have made appearances this week in Denver weather history.

From the National Weather Service:

19-30

In 1875…grasshoppers appeared in great numbers at 10:00 am on the 19th. Thousands landed on the ground. The streets were literally covered with them. Swarms of grasshoppers were seen on each day. All gardens in the city were devastated…and in the countryside the grasshoppers were very destructive to ripened grain. On the 30th the grasshoppers were so numerous as to almost darken the sun.

20

In 1980…winds to 55 to 60 mph were recorded in south Boulder.

In 1982…strong thunderstorm winds blasted the Jefferson County Airport near Broomfield…causing an estimated 3 million dollars in damage. At least 5 hangars and 15 airplanes were damaged…many seriously; one hangar was completely destroyed. Torrential rains accompanied the winds. Heavy rains also dumped on Boulder where 1.65 inches fell in just 15 minutes…causing street flooding. Wind gusts to 72 mph were recorded in Boulder. Over half an inch of rain fell in just 5 minutes in Littleton where two homes were struck by lightning. Lightning also struck a house in Arvada where over an inch of rain sent Ralston Creek over its banks. Strong winds accompanied the storms.

In 1984…slow moving thunderstorms dumped 1.25 inches of rain in Evergreen…causing street flooding. A half inch of rain fell in just 18 minutes in southeast Denver. Littleton and Boulder were also drenched with about an inch of rain. Rainfall totaled 0.92 inch at Stapleton International Airport.

In 2001…severe thunderstorms produced damaging winds and large hail across metro Denver. Hail as large 1 inch in diameter fell in Aurora near Cherry Creek. Strong thunderstorm winds gusting as high as 58 mph blew the roof from a building between Thornton and Denver and toppled several trees in Denver. One tree landed on a mail truck. Other thunderstorm winds were clocked to 60 mph near Parker… 62 mph in Broomfield…and 61 mph at Denver International Airport.

In 2006…a tornado (f0) touched down near Bennett…but caused no reported damage.

In 2013…severe thunderstorms pounded the southern Denver suburbs and other parts of the Front Range. In Jefferson County…water rescues were reported for some people in stranded cars. In the Ken Caryl area…large hail from one inch to 1 3/4 inches in diameter was reported. On West Chatfield Avenue in Jefferson County…hail runoff gathered six inches deep in spots and “hail plows” were sent out to clear some streets. Hail up to one inch in diameter was also reported near Castle Rock.

21

In 1876…heavy thunderstorm rain and hail struck the city. Hail stones as large as partridge eggs accumulated to a depth of 1 1/2 feet over eastern portions of the city. The heavy rainfall flooded streets and gutters. However… No significant damage was reported. Rainfall totaled 0.85 inch in central Denver.

In 1903…a thunderstorm produced west winds sustained to 42 mph with gusts to 48 mph.

In 1957…heavy thunderstorm rainfall and hail over the bear creek basin flooded portions of State Highway 8 in and near Morrison. There was also minor property damage in Morrison.

Thornton’s Friday and weekend warm up, should stay dry

Friday, August 18th, 2017 4:55am MST

A shift back to summer-like weather conditions for the three day period. We will be seeing plenty of sun, dry conditions and temperatures at or above normal.

For Friday look for sunny skies for most of the day with only a few clouds intruding by late afternoon into the evening. Overall conditions will be calm and dry. Temperatures will be topping out near the 90 degree mark. Overnight tonight skies remain mostly clear with lows to the upper 50s.

Saturday looks much like today but with the mercury climbing a little bit further. Again, sunny skies will be above and we will remain dry. Highs should top out in the low 90s. Some moisture aloft does arrive overnight Saturday into Sunday morning leading to a bit of cloud cover. Lows Saturday night dip to near 60 degrees.

Sunday continues the same general pattern but with a few clouds above. Highs again will be in the low 90s. At this time we do expect to remain dry.

Have a great weekend!

Thursday brings near normal temps, only slight chances for storms

Thursday, August 17th, 2017 4:55am MST

A bit of a drier and a good bit warmer weather forecast for Thornton today. Less moisture means we will likely remain dry today and temperatures will be climbing to highs right near the average of 87 degrees for the date.

We start out with mostly sunny skies and will enjoy those conditions for the morning. The afternoon will offer up a few more clouds. The midafternoon through early evening hours may see an isolated thunderstorm pop up but there won’t be many and those that do should only offer gusty winds, perhaps a few drops of rain. Highs today will top out around 86 degrees.

Tonight look for partly cloudy skies with highs in the upper 50s.

Cooler temperatures, damp conditions for Wednesday

Wednesday, August 16th, 2017 4:58am MST

The cold front that moved through late yesterday has ushered in a bit of a change in the weather pattern. Temperatures today will be a good bit cooler and while we may see a few drops of rain, overall things won’t be as wet.

Look for partly sunny skies to start things off today and similar sky conditions above throughout the day. A few sprinkles of rain will be possible through the morning then this afternoon, perhaps some thunder. However, we aren’t expecting much in terms of precipitation. Temperatures today will top out in the mid to upper 70s.

Tonight skies will clear and it will dry out. Overnight lows will be in the mid-50s.

Thornton’s Tuesday brings slightly cooler temps, better chance for storms

Tuesday, August 15th, 2017 5:02am MST

Another somewhat unsettled afternoon and evening. A passing cold front is going to bring better opportunities for us to see storms late in the day today.

We start out with mostly sunny skies and those will continue through the morning before coverage increases this afternoon. Temperatures will be on a steady climb to a mid-afternoon high in the mid-80s before cooling down.

This afternoon brings a chance for thunderstorms with the best opportunity coming from about 1:00pm to 5:00pm. Some severe level storms will be seen but right now it appears those should be to our east and north.

Tonight will be partly clear with lows near 60 degrees.
