On this date through the 24th, locations in and near the foothills of northern Colorado outside of Denver received the greatest snow of the year as a winter-like storm moved into the area. Snow fell at a rate of 2 to 3 inches per hour as deep upslope combined with a moist and unstable air mass. The snow began in the foothills above 7,500 feet during the evening. By sunrise the next day, the snow level dropped to 5,000 feet. The hardest hit areas extended from I-25 to the foothills. Snowfall totals in the foothills ranged from 18 to 42 inches. In Denver, 8 to 18 inches fell. Some snowfall totals included: 36 inches at Coal Creek Canyon, 31 inches at Nederland & Wondervu, 20 to 24 hours near Blackhawk, Echo Lake and North Turkey Creek Canyon, 15 to 19 inches at Boulder, Central City, Conifer, Evergreen, Georgetown and Louisville, 8 to 14 inches at Arvada, Broomfield, Westminster, Wheat Ridge, Castle Rock and Ken Caryl Ranch.
A horrific hailstorm moved southeast from Pennsylvania across Garrett County, MD and into the Eastern Panhandle of West Virginia. It had weakened some as it crossed Garrett County and the Allegany Front, but as it passed east of Keyser, WV, hail began to increase in size once again. By the time it reached Capon Bridge in eastern Hampshire County, WV, the size of the hail had grown from golf balls to baseballs. As it moved into Frederick County, VA, the hail storm continued to grow dropping golf ball size hail in a swath now reaching from the north of Winchester, south to about 10 miles away in Stephen City. The intensity of the hail stripped and shredded leaves and bark from the newly budding trees. Hailstones grew to the size of softball (4 inches in diameter) just east of Winchester. The storm continued east through Clarke County, southern Loudoun and northern Fauquier doing considerable damage to Middleburg, then across Fairfax County hitting Centreville, Chantilly, Fairfax, Burke, Springfield, and Lorton with golf ball to baseball size hail. It crossed the Potomac River and weakened just slightly. It moved across northern Charles, clipped southern Prince Georges and then into Calvert County with 1 inch to 1.5-inch diameter hail and onto the Chesapeake Bay continuing southeast to the ocean. The damage left behind was incredible. In Northern Virginia alone, it amounted to over $50 million dollars in losses to public and private properties. Some communities saw a third of the homes with siding and roof damage. Some required total replacement. Windows were broken, cars dented and windshields smashed. Piles of shredded plant debris were left on the ground in the storm path. In about 6 hours of time, this one thunderstorm, moving at about 50 mph, did $75 million dollars in damage. There have been other bad hailstorms to hit this area before, but none to cause this much damage to property.
A cyclone battered India's remote northeastern Assam state, killing at least 36 people and injuring 1,500.
Spring thaw caused local rivers to flood Kashechewan in Northern Ontario causing nearly 900 residents to flee for the third evacuation in less than a year. The rising rivers flood homes, and ice debris snaps a valve in the reserve's water treatment plant leaving residents without tap water.
On this date through the 24th, a storm system intensified over southeastern Colorado bringing heavy rain and snow across much of north-central and northeast Colorado. Severe thunderstorms preceded the storm system affecting the urban corridor. Nickel size hail was reported in Boulder and a small landspout touched down near Byers. The next day, heavy snow fell in the foothills west of Denver and Boulder where storm totals ranged from 1 to 2 feet. Heavy snow also fell along the Palmer Divide with totals ranging from 10 to 16 inches. The heavy wet snow caused several power outages. In some instances, it took several days to restore power. Several road closures were reported; including I-25 and I-70 with several accidents.
For a second straight day, record heat covered southern Alberta, Canada. Medicine Hat, Alberta set a new high temperature record with 88°. Record highs were also set at Lethbridge: 83.5°; Calgary: 78.4° and Banff: 71.4°.
The cold spring continued across much of the Rockies and Plain states. Having been snowed out in previous days, the Colorado Rockies played a day-night doubleheader at Coors Field in Denver against the Atlanta Braves under cloudy skies and the game time temperature at 1:10pm MDT was 23. It was the coldest temperature for baseball in Coors Field history. The second game at 6:40pm MDT was a much warmer 30.
