\"This<\/a><\/p>\n

June means severe weather in Colorado and our look back at this week showcases that fact. Numerous, historical events have occurred during this week in the past including the disastrous Hayman fire and the infamous 1988 Denver tornadoes.<\/p>\n

From the National Weather Service:<\/p>\n

7-9<\/p>\n

In 1979\u2026rain\u2026at times with thunder on the 7th\u2026fell almost continuously through the morning of the 9th. Rainfall totaled 2.28 inches at Stapleton International Airport over the 3 days. High temperature of only 49 degrees on the 8th was a record low maximum for the date.<\/p>\n

9<\/p>\n

In 1900\u2026an apparent cold front produced north winds to 42 mph with gusts to 47 mph.<\/p>\n

In 1923\u2026heavy rainfall totaled 2.18 inches in downtown Denver\u2026where northwest winds were sustained to 27 mph. Heavy rain also fell in Boulder\u2026causing flooding on Boulder and south Boulder creeks.<\/p>\n

In 1939\u2026post-frontal sustained northwest winds to 35 mph produced some blowing dust\u2026which reduced the visibility to one mile at times during the afternoon. Dusty conditions prevailed into the early evening. The airport station reported a maximum wind of 56 mph. A few minor injuries and some damage resulted. A few trees were uprooted\u2026some fruit was blown from trees\u2026and a section of power lines was blown down.<\/p>\n

In 1967\u2026a small tornado damaged trees and a dwelling in south Denver. The storm touched down at the intersection of 1st Avenue and Harrison Street and moved northeast to the intersection of 3rd Avenue and Albion Street. Damage included 3 small roofs removed\u202615-20 large trees uprooted\u2026one car overturned and thrown against a house\u2026 Plus other minor damage. A funnel cloud reported at the same time 10 miles north of Denver possibly touched ground. Later\u2026funnel clouds were reported 12 miles south-southeast of Stapleton International Airport\u202610 miles southwest\u2026and 5 miles north. A tornado was sighted 3 1\/2 miles east of Stapleton International Airport by weather bureau personnel for a duration of 5 minutes. Heavy rain and some hail fell over much of the area.<\/p>\n

In 1974\u2026the start of the shortest seasonal snow free period on record\u202694 days\u2026occurred with the last snow of the season\u2026a trace\u2026on the 8th. The first snow of the next season occurred on September 11th when a trace of snow fell at Stapleton International Airport. A funnel cloud was observed just east of Aurora and a small funnel was sighted just northeast of Stapleton International Airport.<\/p>\n

In 1985\u2026a thunderstorm wind gust to 62 mph was reported at Golden Gate Canyon in the foothills west of Denver.<\/p>\n

In 1986\u2026a thunderstorm\u2026which dumped heavy rain and caused some street flooding across north metro Denver\u2026produced a small tornado 5 miles east of Brighton. No damage was reported.<\/p>\n

In 1987\u2026strong thunderstorm wind gusts in Conifer destroyed a porch on a house; the wind gust apparently picked up the porch and dropped it on a man\u2026killing him. The wind also damaged the roof of the house and a nearby barn. The same thunderstorm spawned a tornado\u2026which touched down briefly just south of Lakewood. No damage was reported. Up to 3 inches of rain fell in a short time 8 miles southwest of Littleton. A few businesses in Englewood suffered minor water damage. A tornado was sighted between Watkins and Bennett.

In 2002\u2026high temperatures\u2026low relative humidities\u2026and strong gusty winds allowed the Hayman wildfire\u2026located in the foothills to the southwest of Denver\u2026to become the largest wildfire in the state\u2019s history. Although the fire was initially started by a U.S. Forest Service employee\u2026the ongoing drought and dry conditions allowed the fire to spread rapidly out of control. The wildfire consumed nearly 138 thousand acres of forest land and 133 homes before it could be contained and finally extinguished on June 30th. About 1800 households had to be evacuated during the blaze. Southwest winds aloft swept the smoke plume directly over metro Denver\u2026creating poor air quality and blocking the sun. Much of metro Denver choked on smoke with the southern suburbs receiving the most. Smoke and ash restricted surface visibilities to a mile or less at times in the Denver and Castle Rock areas and to 2 miles at Denver International Airport.<\/p>\n

In 2003\u2026thunderstorm winds gusted to 51 mph at Denver International Airport. The storm produced only a trace of rain.<\/p>\n

The combined damage to homes and vehicles\u2026not including commercial buildings\u2026was estimated at 146.5 million dollars\u2026making the event the 4th costliest insurance disaster in the state\u2019s history.

9-10<\/p>\n

In 1864\u2026high water from melting snow combined with heavy rains over the upper reaches of the South Platte River forced the river over its banks and caused flooding of low lying areas along the river in the city. The amount of rainfall in the mountains and in the city is unknown.<\/p>\n
