623 NOUS45 KBOU 250859 PNSBOU COZ030>051-252300- Public Information Statement National Weather Service Denver/Boulder CO 259 AM MDT WED SEP 25 2024 ...Today in metro Denver weather history... 25 In 1873...a fire was sighted in the woods near Platte Canyon... probably caused by high winds blowing sparks among the timber. In 1896...an apparent cold front produced northeast sustained winds to 40 mph with gusts to 48 mph. In 1910...a thunderstorm produced sustained north winds to 51 mph. This was the highest recorded wind speed in the city in September at the time. In 1936...a vigorous cold front produced a deadly dust storm in the city. North winds sustained to 36 mph with gusts to 38 mph produced much blowing dense dust...greatly restricting the visibility. The temperature plunged from a high of 84 degrees to a low of 38 degrees by midnight. The weather observer described the event with the following. "At 6:00 PM the temperature was 82 degrees and the wind velocity was only 4 mph; but with the wind shifting to the north and the barometer rising quite rapidly...the temperature fell sharply. By 6:30 PM...the wind velocity increased rapidly and by 7:00 PM had reached a maximum sustained velocity of 36 mph...bringing with it clouds of dust which had been picked up by gale force winds in southern Wyoming and northern Colorado...covering the city. The visibility was generally reduced to about 1/4 mile; however...the whirling of the dust down the streets and alleys...the visibility was at times somewhat less. Airplanes were grounded...traffic was halted at times...and homes filled with dust. The strong winds damaged electric power and telephone lines...leaving homes in darkness for a few hours in the city and for 18 hours in suburban towns and putting 2500 telephones out of service because of broken lines. An electric lineman was killed while repairing damage by the high winds. The dust storm was followed by rain that began falling at 10:55 PM...which turned to snow during the early morning hours of the 26th. A major snow storm followed on the 27th through the 29th." In 1999...high winds developed in the foothills of Boulder County. Winds gusted to 90 mph at Wondervu. 25-26 In 1908...apparent post-frontal rain changed to snow overnight and totaled 6.5 inches in downtown Denver. This was the first snow of the season. Precipitation totaled 0.76 inch. North winds were sustained to 39 mph on the 25th. 25-27 In 1996...an early season snowstorm brought heavy snow to the Front Range eastern foothills. Snowfall totals included: 8 to 12 inches around Conifer...7 inches on Floyd Hill...and 6 inches at both Bailey and Chief Hosa. Snowfall totaled only 4.7 inches at the site of the former Stapleton International Airport. This was the first measurable snow of the season. After the passage of a strong cold front...north winds gusted to 38 mph at Denver International Airport on the 25th. $$
