November 2010 1st or 2nd warmest on record; ZombieSat saga ends

November 2010 was the globe's second warmest November on record, according to the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC). NASA's Goddard Institute for Space Studies rated November 2010 the warmest November on record. Both NOAA and NASA rated the year-to-date period, January - November, as the warmest such period on record. Global satellite-measured temperatures for the lowest 8 km of the atmosphere for November were the 5th or 3rd warmest on record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH), respectively. UAH rates the year-to-date period, January-November, as the 2nd warmest such period in the satellite data record, behind 1998. The record or near-record November global warmth is remarkable, given that we are in the midst of a moderate strength La Niña episode in the Eastern Pacific. The large amount of cold water that upwells to the surface during a La Niña typically causes a substantial cool-down in global temperatures, making a monthly temperature record difficult to set. November 2010 is the only "warmest month on record" as rated by NASA to occur during La Niña conditions. The November temperature record is all the more remarkable since we are near the minimum of the 11-year solar sunspot cycle. Global temperatures are cooler by about 0.1°C for the two years following a solar minimum, compared to global temperatures two years after solar maximum. Our current minimum in solar energy makes it much more difficult to set monthly global temperature records.

An average November for the U.S.
For the contiguous U.S., November was near-average in temperature, ranking as the 46th warmest November in the 116-year record, according to the National Climatic Data Center. The year-to-date period, January to November, was the 19th warmest such period on record. No states had a top-ten warmest or coldest November on record. November 2010 precipitation was also near average. Only Montana had a top-ten wettest November on record, and no states had top-ten driest November.

La Niña in the "moderate" category
The equatorial Eastern Pacific Ocean is currently experiencing moderate La Niña conditions. Sea surface temperatures (SSTs) over the tropical Eastern Pacific in the area 5°N - 5°S, 120°W - 170°W, also called the "Niña 3.4 region", were 1.4°C below average as of December 20, according to NOAA. The Australian Bureau of Meteorology put this number at 1.29°C below average (as of December 19.) Moderate La Niña conditions are defined as occurring when this number is 1.0°C - 1.5°C below average. Temperatures colder than 1.5°C below average qualify as strong La Niña conditions. NOAA is maintaining its La Niña advisory, and expects La Niña conditions to last through the coming winter into spring.

Both El Niño and La Niña events have major impacts on regional and global weather patterns. La Niña typically causes warm, dry winters over the southern portion of the U.S., with cooler and wetter than average conditions over the Pacific Northwest. The Ohio and Mississippi Valleys states typically have wetter winters than usual during La Niña events.

November 2010 Arctic sea ice extent 2nd lowest on record
Northern Hemisphere sea ice extent in November 2010 was the 2nd lowest in the 31-year satellite record behind 2006, according to the National Snow and Ice Data Center. As of December 24, ice extent was the lowest on record for this time of year. Ice volume in November was the lowest on record, according to University of Washington Polar Ice Center.

Major atmospheric pattern shift coming
The unseasonably cold weather over Europe and the Eastern U.S. is due to break between Christmas and New Year's, as the atmosphere undergoes a major shift in its circulation. The very unusual high pressure region over the Arctic is forecast to break down and be replaced by the typical low pressure region we expect to see in winter. After recording some of its coldest temperatures in 17 years this week, the UK may well see record highs on New Year's Eve as a result of the pattern shift. The pattern shift should bring the Eastern U.S. above-normal temperatures during the last few days of 2010, and a major New Year's Eve snowstorm to Iowa, Minnesota, and Wisconsin.

The ZombieSat saga ends?
Last week, I blogged about ZombieSat, the rogue Galaxy-15 communications satellite that failed during a solar storm. ZombieSat has been spewing noise in the C-band microwave region that has been interfering with broadcasts from satellites in its path, including the key SES-1 satellite that relays most of the weather data wunderground and the National Weather Service uses. Within the next week, ZombieSat will close in on its sister satellite, Galaxy-16, which hosts the Public Radio Satellite Service (PRSS) feeds, among others. A few weeks ago, PRSS warned its customers (who include commercial stations as well as the nation's public broadcasters) that there would be a possibility of disruption to its services on or about December 26. But on Friday December 17, Intelsat announced that ZombieSat had lost its "lock" on Earth, resulting in a loss of power that caused the satellite's main interfering transponders to shut down. So it appears the ZombieSat saga is over, and a whole bunch of engineers and operations directors can enjoy Christmas weekend without worrying about a zombie satellite hanging 23,000 miles over their heads.

Happy holidays, everyone!

Probably wont happen for me lol.. but wishful thinking.. Really just need some more data of how far this L will go tho.. Its hard to predict how much snow this early specially for the south..


That would put me in the 3"-5" range. I really hope so! But I have a feeling I will wake up with 50 degrees and rain. Happens (almost) every time.

Man look at that moisture.. I hope it's cold enough for most of that to be snow.. but that's a long shot here in C GA.

While the storm shifted west, the cold air invades faster. It wouldn't be surprising to see some flurries on the backside, but nothing major. If it were to happen, it would happen late tomorrow night into Sunday morning.


Yeah I was thinking the samething.. Just wanted to get another opinion..

The GFS is continuing to show a deeper, stronger storm - compare the 12z and 18z runs.

WRF is coming into agreement with GFS, as well.

Hey Reed.. U think it might be possible that the panhandle of FL could see a snowflake.. lol

NAM has shifted west with the storm as well.. Things are coming together. It's like Henry Margusity said, the upper air pattern favors a storm getting pulled closer to the ULL.

Wow... the 18z gfs has shifted a little bit ever further west,It give us 8-12 inches of snow again... why does the NWS discount it, this is the third run in a row like this, doesnt that consistency mean anything?


It will probably soon once the model that there using isnt being consistent.. If it continues, we will probably c sum big changes.. Tonight or very late tonight is a better chance of know what this system will do, how strong, and so on.. But yea we shall c tho.. I would love to see sum snow flakes here though.. :)
