Weather Almanac - And on this day ...... Weather events and records for this date in History
Posted 30 December 2012 - 10:24
Just after midnight, Altnaharra in Sutherland recorded the UK's December low temperature record of -27.2 °C, also equalling the official alltime low for the UK held on two occasions by Braemar. As winds picked up the temperature rose quickly to -1.0 °C in around three hours. Further increase in temperature finally gave an amazing diurnal range of 28.9C or 29.3C (depending on which source you read, and perhaps whether 21z or 00z is used) which is though to be the UK's greatest on record.

Tropical Storm Zeta forms in the open Atlantic Ocean, tying the record for the latest tropical cyclone ever to form in the North Atlantic basin.
Tropical Storm Zeta was a late-developing tropical storm over the central Atlantic which formed after the 2005 Atlantic hurricane season had officially ended (on November 30), and continued into January 2006. Becoming a tropical depression at approximately midnight on December 30 (UTC), it became the record-breaking thirtieth tropical cyclone of the 2005 Atlantic hurricane season and after intensifing into Tropical Storm Zeta six hours later, it become the season's twenty-seventh named storm. Zeta was one of only two Atlantic tropical cyclones to span two calendar years (the other being Hurricane Alice in 1954-55).
Zeta originated from an area of low pressure on December 29, which previously developed within an upper-level trough. After becoming a tropical storm, the National Hurricane Center continually predicted it would weaken rapidly. Like the previous tropical cyclone, Hurricane Epsilon, Zeta defied these predictions. The storm reached its peak strength on January 2, 2006 before finally dissipating on January 6. As Zeta never approached land there was no impact from the storm other than minor shipping problems. Several ships encountered the storm, and several crews in the 2005 Atlantic Rowing Race were affected by rough seas and high winds.

December 1978 had been very wet. but very cold weather edged southwards during the last days of December.
On the evening of the 30th, an elongated and deep area of low pressure moved eastwards up the English Channel with easterly gales developing on its northern side. Intensely cold and dry Continental air had fed westwards during the preceding day with temps falling below freezing by evening. Snow started late evening, and although it was never very heavy, it blew around and drifted, the coldness and driness of the air making the snow very powdery. Temperatures continued to fall during the snow storm, such that the inside of windows froze over, something I had never seen in snow before; in previous years, snow always meant the cold was coming to an end.
Next morning revealed about 10cm of level snow. The interesting thing about this snow was, that anything that was flat and elevated was blown clear. No snow had settled on slate roofs, and round lamp posts, there were rings of no snow, where the wind blowing round the post had blown the snow away. There were also many interesting cornice shapes on other roofs where snow had blown, but had congealed in the turbulence to the lee.
This snow was then followed by about a week of very cold, but almost completely sunny weather. Beautiful!

The lowest recorded temperature in Europe: -58.1 °C at Ust'- Shchuger, Komi Republic, Russia
Also on this date, a severe blizzard struck southern England on the 30-31st, with deep drifting. New Year's Eve was the coldest for 40 years, with local maxima of -4C.

No sunshine was reported at Westminster, London during the entire month. Just 0.3 hours sunshine in the month was recorded at Kew.
Only 27 hours of sunshine were observed at Fresno, California during December 1900. This is just 9 percent of the total possible sunshine available for the month, making it not only the least sunniest December ever, but the least sunniest month ever there. [ Possibly due to Tule fog? ]

January 1, 1979
The temperature at Maybell CO plunged to 60 degrees below zero to tie the state record set back in 1951 at Taylor Park. (The Weather Channel)
January 1, 1987
A winter storm brought rain and snow and high winds to the Southern and Middle Atlantic Coast Region. The storm, which occurred in a period of unusually high astronomical tides, produced a tide of 9.4 feet at Myrtle Beach SC (their highest since Hurricane Hazel in 1954) which caused a total of 25 million dollars damage in South Carolina.

On this day in 1982, a series of landslides near San Francisco, California, kills up to 33 people and closes the Golden Gate Bridge. In all, an amazing 18,000 different landslides took place in the San Francisco Bay Area following a very heavy rain storm.
Two fast-moving fronts carrying extremely heavy rain passed through San Francisco in a 36-hour period beginning on January 4, during which the area received an amount of rain equal to half its average annual precipitation. Some areas received as much as 24 inches of rain on January 4 and 5. On January 5, the rain began to trigger thousands of separate landslides in the Bay Area hills.
Almost without exception, the slides caught their victims completely unaware. San Francisco State University professor Kai-yu Hsu was in the basement of his home in Tiburon. Suddenly, there was a deafening roar and, within seconds, the home was gone--it crashed into a park at the bottom of a hill. His son, Roland, witnessed the tragedy while standing just outside the home.
In all, about 7,800 homes and businesses were seriously damaged by slides and falling trees. Roads became impassable when mud and large boulders crashed down onto them. The Golden Gate Bridge even had to close due to a landslide. When seven homes in Love Creek collapsed on a hillside, 10 people died instantly. It is believed that between 22 and 33 people were killed in total. Damages exceeded $100 million, and the region was declared a federal disaster area. It was the Bay Area's worst natural disaster since a 1906 earthquake.
Using aerial surveillance in the days following the storm, officials determined that about 18,000 separate slides occurred. In most areas, homes have since been rebuilt on the original lots, using sub-surface pipes and retaining walls to help prevent a repeat disaster

Between January 4th and 10th, 1998, parts of Eastern Ontario and Western Quebec were hit by 3 successive storm fronts that have been called the greatest natural disaster in Canadian history. The storm's greatest impacts were profound and lengthy disruption to daily life and far-reaching economic consequences. The total precipitation, which fell as freezing rain, ice pellets and snow, exceeded 73 mm in Kingston, 85 mm in Ottawa and 100 mm south of Montreal. Canada's largest recorded ice storms, in Ottawa in December 1986 and Montreal in February 1961, left 30 to 40 mm of ice.

The Great Seattle Storm King
Snow drifts of 4 - 6 feet were reported near Seattle.
Storm deposits 20 - 30 inches at sea level and 48 inches in the Olympia area.
14 straight hours of 2+ inch an hour snowfall.
Barometer fell to 28.20 inches or 955 hPa
A windstorm in NW Oregon (during the snowy period in Seattle) resulted in some places losing half of their trees. Trees were actually criss-crossed due to extreme SE winds being followed by extreme west winds.
The city of Seattle quickly organized hundreds of men to shovel off roofs of building that were certain to collapse. They were paid $1.00 an hour. Huge wages by 1880 standards.
A ship that was on the Seattle waterfront during the storm was sunk one foot by the weight of the snow. From that they knew the weight of the snow on that one boat was 100 tons...100 TONS!

(6th/7th January): NORTH SEA SURGE/THAMES ESTUARY SEA FLOOD <br style="font-family: 'Times New Roman'; font-size: medium;">A north to north-westerly severe GALE (GUST speeds ~ 70kn or a little higher, e.g., 73 kn at Spurn Head, Lincolnshire), produced a strong SURGE down the North Sea coast of eastern England (as the filling low slipped away towards Poland), which combined with a high ('spring') tide in the Thames estuary, produced severe FLOODING in the London area as the Embankment was breached in several places with many roads damaged. The sea-level was some 6ft (about 2m) above the predicted level. At least 14 people were trapped and drowned in their homes due to the rapid rise of the water, with thousands left homeless.

On this day in 1996, snow begins falling in Washington, D.C., and up the Eastern seaboard, beginning a blizzard that kills 154 people and causes over $1 billion in damages before it ends.
The Blizzard of 1996 began in typical fashion, as cold air from Canada pushed down and collided with relatively warm winds from the Gulf of Mexico. The clashing weather fronts caused a terrible combination of snow and wind. Snow began to fall in the District of Columbia about 9 p.m.; 12 inches fell over the course of the next 24 hours. In Lynchburg, Virginia, it was worse: A record 20 inches of snow fell in a single day. Since wind gusts were reaching up to 50 miles per hour, snow drifts piled up in many areas and travel was nearly impossible.
As the storm moved northeast, it continued to break records. Newark, New Jersey, received a total of 28 inches over several days. Providence, Rhode Island, received 32 inches and Philadelphia was inundated with 30 inches. The Philadelphia schools were closed until January 16 due to the city's inability to clear the heavy snow promptly from the streets.
Overall, the blizzard took a serious toll on both people and property. A church roof in Harlem collapsed, injuring several people in New York City. Barns all over Pennsylvaniacollapsed under the weight of so much snow. As a precaution, many supermarkets, which often feature large flat roofs, closed across the region. Two buses collided in Pittsburgh and 52 were seriously injured. The storm deaths were mainly the result of traffic accidents, collapsed trees and homeless people dying from hypothermia. In a few instances, people who were trapped in their cars died from carbon monoxide poisoning. Pennsylvania suffered the most deaths, with approximately 80.
President Bill Clinton was forced to shut down the federal government for nearly a week because of the storm. He declared D.C. and nine states to be disaster areas. Estimates of the total property damage suffered ranged from $600 million to $3 billion.
