Historical Weather And Climate Facts For Today

DECEMBER 22ND
HISTORIC WEATHER EVENTS
...1839...
The second of triple December storms hit the northeastern U.S. The storm
produced 25 inches of snow at Gettysburg PA, and gales in New England, but
only produced light snow along the coast. (David Ludlum)
...1961...
Holiday travel was paralyzed over extreme northeastern Kansas, and adjacent
parts of Missouri, Iowa and Nebraska. The storm produced 5 to 15 inches of
snow, with drifts up to ten feet high. (22nd-23rd) (The Weather Channel)
...1983...
On the first day of winter 75 cities reported record low temperatures for
the date, with twelve of those cities reporting record low temperatures for
the month as a whole. The mercury plunged to 51 degrees below zero at
Wisdom MT, and Waco TX set an all-time record low a reading of 12 above
zero. (The National Weather Summary)
...1987...
The first day of winter was a relatively tranquil one for much of the
nation, but heralded a winter storm in the Central Rockies. The storm
produced 40 inches of snow at the top of the Pomerelle Ski Resort, south of
Burley ID, the heaviest snow of record for that location. (The National
Weather Summary) (Storm Data)
...1988...
Strong winds prevailed in the foothills of Wyoming and Colorado. Winds
gusted to 123 mph southwest of Fort Collins CO, and reached 141 mph at the
summit of Mount Evans. An ice storm paralyzed parts of Upper Michigan
during the day. The freezing rain left roads around Marquette MI blocked by
cars and semi- trucks. (The National Weather Summary) (Storm Data)
...1989...
A total of 137 cities across the central and eastern U.S. reported record
low temperatures for the date. Thirty-five of those cities established
record lows for the month of December. Morning lows of 23 degrees below
zero at Kansas City MO, 26 degrees below zero at Concordia KS, and 27
degrees below zero at Goodland KS established all-time records for those
three locations. Unofficial morning lows included 50 degrees below zero at
Recluse WY and 60 degrees below zero at Rochford SD. Broadus MT and Hardin
MT tied for honors as the official cold spot in the nation with morning
lows of 47 degrees below zero. Chinook winds at Cutbank MT helped warm the
temperature 74 degrees, from a morning low of 34 degrees below zero to an
afternoon high of 40 degrees. (The National Weather Summary) (Storm Data)
