275 NOUS45 KBOU 180859 PNSBOU COZ030>051-182300- Public Information Statement National Weather Service Denver/Boulder CO 259 AM MDT TUE JUN 18 2024 ...Today in metro Denver weather history... 17-18 In 1964...from the 17th to the 18th...high winds at speeds of 50 to 60 mph with gusts as high as 75 mph caused damage to homes...power lines...and trees in Boulder. Non-convective west winds gusting to 46 mph caused some blowing dust at Stapleton International Airport on the 17th. 18 In 1875...a windstorm produced sustained winds to 45 mph during the morning hours. Numerous forest fires along the base of the mountains were visible from the city. In 1886...northwest winds sustained to 40 mph were the strongest of the month that year. In 1987...severe thunderstorms produced lightning...large hail... a tornado...heavy rain...and strong winds across metro Denver. Rainfall totaled 2.50 inches in an hour in Wheat Ridge... causing minor flooding. I-25 was flooded in north-central Denver...snarling traffic. Hail 7/8 inch in diameter fell in Louisville with 1 1/2 inch hail near Golden and 1 to 1 3/4 inch hail in and near Castle Rock. A tornado touched down briefly in Castle Rock. No damage was reported. Lightning started a small fire that burned half a cabin near Evergreen. In 1994...a funnel cloud was sighted over Aurora; hail to 1 3/4 inch diameter fell near Brighton; and hail over an inch in diameter fell over Aurora...southeast Denver... Louisville...and Boulder. Lightning struck a home in Henderson 9 miles north of Denver and knocked a hole in the roof...which caused the ceiling to collapse. Hail to 1 1/4 inch diameter was measured at Stapleton International Airport. In 2002...the Hayman Wildfire in the foothills to the southwest of Denver intensified...and the winds aloft carried the smoke plume directly over metro Denver...again creating a dense haze of smoke which blocked the sun. Surface visibilities were again reduced to as low as 1 1/4 miles at Denver International Airport. In 2004...severe thunderstorms produced hail to 3/4 inch in diameter near Morrison...in Littleton...near Conifer...near Castle Rock...and in Aurora near Cherry Creek. In 2013...a landspout tornado touched down at DIA. The tornado sent 10 thousand travelers on the concourse...on planes and in the terminal scrambling to get into tornado shelters. The tornado formed just to the south of Runway 35R and then moved slowly northwest between Runway 35R and 35L...and moved to within one third of a mile of Concourses A and B before dissipating. The tornado moved extremely close if not over the ASOS (Automated Surface Observation System) and another low level wind shear sensor at DIA. The ASOS weather observing system reported a 97 mph wind gust...while the wind shear sensor reported a wind gust to 109 mph at the same time indicative of an EF1 tornado. There was only minor damage noted to the equipment. Nine flights were diverted elsewhere during a tornado warning. Severe thunderstorms also produced large hail up to 1 inch in diameter in Adams and Weld Counties. In 2014...a severe thunderstorm produced large hail up to quarter size near Buckley Air Force Base. At Denver International Airport...a peak wind gust to 55 mph was observed from the southwest...along with 0.37 inches of water. In 2015...a severe thunderstorm produced hail...from 1 to 1 3/4 inches in diameter...near Lafayette...Louisville and Superior. $$
