A fleeting glimpse of winter winter Winter’s first snow fell on Jan. 7, the anniversary of one of Washington’s biggest snowstorms, the Blizzard of 1996. The dusting of snow – 0.4 inches at Reagan National Airport – was not a harbinger of more snow to come. Warm and snow-less weather prevailed for the rest of the meteorological winter, with only a trace of snow recorded in the District in February. The temperature rose above 70 degrees on six days and only dropped below freezing a few times, making February 2017 the warmest on record. (WTOP/Dave Dildine) (WTOP/Dave Dildine)

High winds rip through region The year’s highest winds roared across the region just before midnight on Feb. 12 when a powerful front swept through the region. Winds gusted to 65 miles per hour at Reagan National Airport and 73 miles per hour at Joint Base Andrews. More than 30,000 power outages were reported across Maryland, Virginia and D.C. The high winds toppled countless trees, including this mature hardwood on Thornapple Street in Chevy Chase, Maryland. (WTOP/Kathy Stewart) (WTOP/Kathy Stewart)

Rare winter tornado The unseasonably warm weather gave rise to powerful thunderstorms at the end of February. The National Weather Service confirmed that a rare winter tornado struck Charles County, Maryland, on the final Saturday of the month. Shingles were torn, siding was peeled and a carport collapsed onto several vehicles as it tracked from Smallwood Shopping Center over the Huntington Apartments east of Waldorf. The twister was one of only three ever documented in the state of Maryland during the month of February. (WTOP/Dave Dildine) (WTOP/Dave Dildine)

Rotating supercell strikes Montgomery County On April 21, an intense, rotating thunderstorm blew into the northern suburbs.

Dazzling May light show The stormy spring continued with additional volleys of hail and high winds. A dramatic lightning show flickered across the skies above the region late on May 18. The storm clouds in many locations also boasted bubbly undersides known as mammatus formations. A few trees were felled by strong winds gusts in Burke, Woodbridge and Dumfries, Virginia, but the reported damage was relatively minor. (WTOP/Dave Dildine) (WTOP/Dave Dildine)

Summer deluge During the summer, several episodes of monsoon-like rains drenched parts of the region. On July 28, 4.56 inches of rain was recorded at Reagan National Airport. Montgomery County, Maryland, saw the highest rainfall, with some areas receiving almost 7 inches; nearly half of that total fell in just 45 minutes according to the National Weather Service. Arlington County topped other Virginia counties at 5.45 inches. Several streams and river gauges reached flood stage or approached flood stage, including Rock Creek. The rain was so bad that it postponed Friday night’s Mystics game due to a leak at Verizon Center. (WTOP/Dave Dildine) (WTOP/Dave Dildine)

Record-breaking fall heat Freakishly warm, muggy weather impinged on the region in October and early November. It was the third warmest October on record the District. High temperatures frequently soared into the 80s during the first half of of the month. For three straight days, the nighttime temperature failed to fall below 72 degrees; the low of 75 degrees was the warmest low temperature on record for the month. The first two weeks of the month saw oppressive, summerlike humidity with dewpoints measured in the upper 70s at times. Dozens of runners at the Army Ten-Miler were treated for heat-related illness before the race was downgraded to a “recreational run” as a safety precaution. Cooler weather gradually settled into the D.C. area by the second week of November. The season’s first burst of arctic air swept over the mid-Atlantic on Veterans Day. On that Saturday, a daily record low temperature of 26 degrees was set at Reagan National Airport – the first record low established during the month of November since 1978.

Early December snow Following an abnormally warm and dry autumn, an early season snowfall powdered the region on Dec. 9. Light snow fell for most of the day and by evening between 1 and 3 inches had accumulated on the ground. It was the first December snow accumulation D.C. had seen since 2013. The storm’s track and impacts were similar to the first bout with winter weather that grazed the region 11 months earlier, with the heaviest snow falling across southern Maryland, central Virginia and the Delmarva Peninsula.
