consecutive days with the highest temperature...94 degrees...
recorded on both the 4th and 6th.

5-13 In 2010...the Fourmile Canyon Wildfire...northwest of Boulder...
broke out on the morning of the 5th. It originated from
an unattended fire pit at a local residence. The wildfire
quickly consumed 5 1/2 square miles or 3500 acres the
first day...and forced the evacuation of over three
thousand residents. Erratic 45-mph gusts sent the fire in
two directions at times. Very dry weather conditions
preceded the fire. The combination of strong winds...low
relative humidities and dry fuels allowed the wildfire
spread rapidly through the steep...heavily forested terrain.
The flames were reportedly 20 to 50 feet in length. Towns
within the burn area included Salina...Wallstreet and Gold
Hill. The dry conditions coupled with gusty winds ranging
from 45 to 64 mph persisted for several more days. Fire
managers used as many as 700 firefighters and support
personnel from 35 agencies and seven air tankers to battle
the wildfire. A total of 6181 square acres or
approximately 10 square miles were burned. The Fourmile
Canyon Wildfire was the most destructive fire in Colorado
history in terms of the damage to personal property. It
destroyed 171 homes with an estimated cost of 217 million
6 In 1940...a thunderstorm pelted the city with small hail.
The storm produced some lightning damage. One woman was
stunned by a bolt which struck near her. Heavy rain from
the storm raised the level of Cherry Creek by more than
3 feet during the height of the storm. Rainfall downtown
was only 0.26 inch.
In 1988...strong winds blew down two houses that were under
construction in Castle Rock. Northwest winds gusted to 44
mph at Stapleton International Airport.
In 1993...a man was struck and killed by lightning while
standing outside his home in unincorporated Arapahoe County
11 miles south of Denver. Lightning also struck a cabin in
Marshdale...20 miles southwest of Denver...which started a
fire and damaged one room and a portion of the roof.
In 1995...hail as large as 3/4 inch in diameter fell in Coal
Creek Canyon in northern Jefferson County.
In 2001...a thunderstorm dropped 3/4 inch diameter hail in
Aurora near Cherry Creek.
