October 2010 was the globe's eighth warmest October on record, according to the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC). NASA's Goddard Institute for Space Studies rated October 2010 the third warmest October on record. Both NOAA and NASA rated the year-to-date period, January - October, as the warmest such period on record. October 2010 global ocean temperatures were the 10th warmest on record, and land temperatures were the 6th warmest on record. Global satellite-measured temperatures for the lowest 8 km of the atmosphere were the 7th or 2nd warmest on record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH), respectively. UAH rated the year-to-date period, January-October, as the 2nd warmest such period in the satellite data record, behind 1998.

For those interested, NCDC has a page of notable weather highlights from October 2010.

Eleventh warmest October on record for the U.S.
For the contiguous U.S., it was the 11th warmest October in the 116-year record, according to the National Climatic Data Center. The year-to-date period, January to October, was the 19th warmest such period on record. Two states had a top-ten warmest October on record--Wyoming and Montana. No states were colder than average.

U.S. precipitation
For the contiguous U.S., October 2010 was the 39th driest on record. Florida had its driest October in the 116-year record, and two other states had top-ten driest Octobers--Missouri and Texas. Nevada had its wettest October on record, and five other states had a top-ten wettest October--New York, Vermont, New Hampshire, Maine, and California.

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 1.3°C below average during the first two weeks of November, according to NOAA. The Australian Bureau of Meteorology put this number at 1.23°C below average (as of November 14.) 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. I'll have a full analysis of what La Niña might mean for the coming U.S. winter in a post next week.


Figure 2. Departure of surface temperature from average for the first half of November for the Arctic. Record low sea ice extent during this period has led to three "hot spots" with temperatures up to 12°C (22°F) above average where the sea ice loss was greatest. This unusual warmth is likely to have significant impacts on weather patterns across much of the Northern Hemisphere during the coming months. As I discussed in my post The climate is changing: the Arctic Dipole emerges last December, Francis et al. (2009) found that during 1979 - 2006, years that had unusually low summertime Arctic sea ice had a 10 - 20% reduction in the temperature difference between the Equator and North Pole. This resulted in a weaker jet stream with slower winds that lasted a full six months, through fall and winter. The weaker jet caused a weaker Aleutian Low and Icelandic Low during the winter, resulting in a more negative North Atlantic Oscillation (NAO). This pattern typically brings exceptionally cold and snowy winters to eastern North America and Europe. The winter of 2009 - 2010 saw the most negative NAO since record keeping began in 1950, which resulted in an upside-down winter in North America--unprecedented snowstorms and the coldest winter in 25 years in the U.S., and the warmest winter on record in Canada. The unusual negative NAO conditions may have been due, in part, to the unusually high Arctic sea ice loss the previous summer (3rd greatest on record.) The latest GFS forecast predicts that the NAO will go strongly negative for the remainder of November, resulting in a major cold blast for the Eastern U.S. and Western Europe.

October 2010 Arctic sea ice extent 3rd lowest on record
Arctic sea ice extent in October 2010 was the third lowest in the 31-year satellite record behind 2007 and 2009, according to the National Snow and Ice Data Center. Sea ice extent as of today (November 19) is the lowest on record for this time of year, according to ice extent imagery at the University of Bremen. Ice volume in October was the lowest on record, according to University of Washington Polar Ice Center.

I'll have a new post on Monday.

eleven days to the official end to the hurricane season. after a pounding from Tomas here in St Lucia we have yet to receive some respite from the inclement weather. For the last 3 days we have been subjected to flash floods from the surface trough to our east. the whole island is affected and yesterday commercial actvity in the capital castries came to an abrupt halt .due to the excessive flooding. what now concerns me ,is the area of disturbed weather to the southeast of the islands. there is some cyclonic turning near 5N 40W. Shear is low and is forecast to remain so for the next two days. this could be another problem as this system moves west into a favourable environment. i will monitor this area very closely for any surprises

Warnings

Greater Victoria
10:55 AM PST Friday 19 November 2010
Snowfall warning for
Greater Victoria continued

5 to 10 cm of snow tonight.

This is a warning that significant snowfall is expected or occurring in these regions. Monitor weather conditions..Listen for updated statements.

A building Arctic ridge of high pressure over the British Columbia interior is producing strong outflow winds through the coastal valleys of the province and as a result cold air has pushed out to the coast. This cold air is forecast to combine with a low pressure system off Vancouver Island tonight to produce the first widespread snowfall of the season.

5 to 10 cm of snow is forecast for metro Vancouver, East Vancouver Island, Greater Victoria and the Southern Gulf Islands with the highest amounts over higher terrain. Locally higher amounts are also possible along East Vancouver Island where outflow winds will pick up moisture over the strait of Georgia.

The strong northeasterly outflow winds are expected to rise to 90 km/h with gusts to 110 over the Central Coast - coastal sections and up to 70 km/h with gusts to 90 over the southern sections of Howe Sound this evening.

The Arctic airmass will also combine with the strong northeasterly outflow winds to produce low windchill values below minus 20 degrees over the inland sections of the north and central coast. The strong winds and cold windchills are expected to moderate later Saturday as the Arctic ridge and the pacific low weaken.

Why does it always warm up for Thanksgiving and Christmas every year in the Tampa Bay area? This last winter was the only one that had cool weather for both days, but we also had sleet and snow last winter and one of the coldest winters ever and a record low of 24 in January, only 5 degrees above the all time coldest temp ever recorded here of 19 here.

The funny thing is, even though we did have finally a cool Thanksgiving and a cool Christmas, it was quite warm still compared to how cold last winter was.


I'm glad we don't get bitter cold winters here in Florida, but I wish it would regularly be cooler here during the winter. I'm an outdoorsman, so hunting and fishing is a lot more important to me then being a pretty boy and spending my life sitting on the beach getting tans and trying to hit on girls, what a boring way of life, and not very fulfilling for a man, no wonder many dudes are such wussies in Florida! lol

I don't know why sitting out on the beach in 90 degree heat is darn popular to millions of people. I love getting sun, but I get sun just working hard out on my land or fishing out in the intercoastal.

Well, it's a balmy 44 F today. There was frost on the car when I drove my daughter to school. I've got a shirt and big sweater right now and I'm still freezing. Going down to 34 tonight, might get to 50 tomorrow. Down to 31 tomorrow night.

So buck up, you guys, with your highs in the 60's and 70's.

At least you're in the warmer part of the state :-)

Thanks for the update Dr. Masters

Not looking good for dry season this year for us Floridians. Could be quite ugly come May-June when the rains kick in, if they kick in that is. The map below illustrates what this rainy season produced. (Click Map For Full Size)

What rainy season?

I'm not really sure that 94L should have ever been re-instated. Looks like the Season will hopefully wind down as one of the the more busy season but, one that created less harm for most. Gotta say the ConUs was somewhat spared this year....Maybe even a little lucky.
I don't think we'll be lucky next year.

Okay just wanna say that the predictions for next hurricane season comes out in about 2-3 weeks,and I predict that the numbers will look something like this 15-17 storms.Faverable conditions will last into next hurricane season.
it will be another 18 to 20 with 12 to 14 becoming canes

"It's more and more clear to those paying attention, isn't it?"

The tripping point has been reached and from now on you have to be delusional to not realize we are in for some BIG changes..

31. IKE
TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
100 PM EST FRI NOV 19 2010

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

DISORGANIZED SHOWERS AND A FEW THUNDERSTORMS CONTINUE IN ASSOCIATION
WITH A WEAK AREA OF LOW PRESSURE LOCATED OVER THE GULF OF HONDURAS
TO THE WEST OF THE BAY ISLANDS. THE LOW CENTER IS EXPECTED TO MOVE
INLAND OVER BELIZE AND GUATEMALA LATER TODAY...AND DEVELOPMENT IS
NOT EXPECTED. THERE IS A LOW CHANCE...NEAR 0 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE BEFORE IT MOVES INLAND. THIS
DISTURBANCE COULD STILL PRODUCE LOCALLY HEAVY RAINFALL OVER
PORTIONS OF BELIZE...GUATEMALA...AND THE SOUTHERN YUCATAN PENINSULA
OF MEXICO DURING THE NEXT COUPLE OF DAYS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
