NE.Wx Snowfall Forecast Contests

"Mean seasonal snowfall (November - March 1948 through 2006) in inches for Neutral years (top). Lower left map is the difference in snowfall between El Niño years and Neutral years. Lower right map is the difference in snowfall between La Niña years and Neutral years." (Climate Prediction Center)

CW going with distaff-leaning 'la Nada' ENSO this winter...so the top map...'Neutral Year Mean'...would be the expected snowfall distribution entering the upcoming winter. Looks favorable for an active contest season.

CPC/s ENSO Impact page also depicts temperature and precipitation anomalies.

WFO DTX issued its winter outlook this week. Its focus is the upper mid-west in general and Michigan in particular; however...it does have large-scale information of interest covering the NE CONUS.

NE.Wx/s annual ‘Season-total' Snowfall Forecast Contest is your absolute best...biggest...and probably ONLY chance to be recognized for your long-range forecasting acumen; a recognition you so richly deserve.

Not only that...but if you win the Contest...you get a copy of "The Snow Booklet"...by Nolan J. Doesken and Arthur Judson or "New England Weather New England Climate"...by Gregory Zielinski and Barry Keim

What other incentive could you possibly want to enter the Contest ?

The reigning NE.Wx ‘Season-Total’ Snowfall Forecasting Champ-een is Duke kc2dux
Last year/s results here.

Forecast element: sum-total season snowfall

Visit the website to enter your forecast. Follow the link from 'Enter Season-total Forecast.'

As always...there/re no costs...fees...or annoying requests for personal information to enter.

The Contest is open to any and all of the following:
Amateur and professional forecasters; broadcasters with or without trained Seals; weather-biz types and wanna-bees; wish-casters...astrologers...and other class of dreamers; Pollyannas or Cassandras; registered Nostradamusts; non-violent megalomaniacs; woolly-bear caterpillars or their agents; pest detectives...NE.Wx Usenet NG or GoogleGroup regulars and lurkers...refugees from EUSWx...StormVista...Golden Snowball...and meteorologists.

Trolls, goats, hat3-lsiters, and psests need not apply.

Update:
Deadline for entries has passed. Forecasts have been posted on the web site.

Over 60 new snowfall records were set in the wake of last Wednesday/s strong early autumn nor'easter over the Upper Mid-west...Mid-Atlantic...and New England. See the 'record breaking' station list here.

If this pattern contiunes...the regular snowfall forecasting season will start early.

Larry Cosgrove issued a cold and snowy outlook for the upcoming winter today.
See it here.

It/s interesting to note where in the world snow has been observed earlier than usual.

Snowfall causes slick roads, school closings in WNC (10/28)

"“We don’t usually get these events this early, but it’s not unheard of,” weather service meteorologist Scott Krentz said. “Normally we don’t see snowfall occurring until like the third week in November.
[...]
Snowfall amounts ranged from 3 inches in the Haywood County community of Cruso, 2 inches in Newland, Weaverville, Canton and Mars Hill to less than an inch in other locations."

Winter comes early to Britain (10/28)

"Winter has come early to Britain with frost and snow forecast for most of the country over the next three days.
[...]
Snow and gales are forecast for northern Scotland today, while most of England and Wales could see sleet and snow showers later, according to the weather centre Meteogroup."

Rare early snowfall forecast for Capital Region (10/27)

"The National Weather Service [in Albany, NY] predicts up to three inches of snow will fall in the Capital Region late Tuesday. If that happens, it will be just the tenth time in more than 130 years the area saw accumulation on a single October day. Of those nine previous instances, just two included more than an inch of snow.
[...]
"In the time since [recording keeping began in 1874], the Capital Region received more than an inch of snow on a single October day on Oct. 28, 1952, when two inches were recorded, and on Oct. 4, 1987, when nearly seven inches were recorded in Albany."

Winter arrives early with snowfall across the GTA (10/21)

"If you can believe it, six centimetres (~2.5") of snow is already on the ground in Orillia.

"Snowfall is being reported all across southern Ontario, with flurries coming down in parts of Toronto and York region and white-out conditions further north into the Barrie area and cottage country."

Winter arrives early in snowy Saskatchewan

"Environment Canada says that as much as a dozen centimetres (~5") of snow fell on Sunday (10/12) and the white stuff continued to fall overnight."

Cool before and after pix.

"With the exception of the huge polar ice sheet in Antarctica, the globe’s cryosphere, or ice zone, is melting, and nowhere is that more evident than in the glaciers of Alaska. Bruce F. Molnia, a research geologist at the U.S. Geological Survey, has compiled a striking set of photographs in a new book, Glaciers in Alaska, that documents that retreat.

Comparing archival photographs from the first half of the 20th century with present-day pictures, Molnia illustrates a stark reality: 99 percent of Alaska’s 100,000 glaciers are shrinking, and those at elevations lower than 4,900 feet are thinning and retreating with stunning swiftness."

Probably a good sign CPC/s 1.5 month...long-lead outlook hasn/t painted a cold...wet signal over the NE CONUS.

From Reuters...
WSI forecaster...Todd Crawford...said in a press release today...
"The ocean temperature signals in the Pacific Ocean are generally suggestive of a relatively warm period in most of the eastern United States during late fall and winter, with the exception of December.

"Further, neither ocean temperatures in the Atlantic nor the snow cover build up at Arctic latitudes are suggestive of sustained cold and snowy weather in the East this upcoming winter. We expect the best chances of sustained cold weather to occur prior to the New Year, with mild conditions prevailing after that."

The UKMET Office...the British version of the US NWS...produces a statistical NAO forecast for the upcoming winter.
The forecast for 500 mb heights is based on a analysis of observed and the 'predictor pattern' of SST anomalies in the northern Atlantic Ocean.
"By taking the observed SST anomaly for May (figure above) and calculating how it projects onto the predictor pattern we can make a prediction for the winter NAO. If the projection is positive (i.e. the anomaly pattern looks similar to the predictor pattern) then the prediction is for a positive winter NAO. Conversely, if the observed May SST anomaly projects negatively onto the predictor pattern (i.e. it looks like the reverse of the predictor pattern) then we would predict a negative NAO."
"The figure below shows that the predicted winter NAO index for 2008/9 is weakly positive at +0.1 with a standard error of ±1.0. The small amplitude of the predicted index relative to the error bar means that the NAO prediction this year provides little signal for below- or above-normal European winter temperatures or precipitation. However, the prediction is consistent with a cooler, drier winter over northern Europe as a whole than experienced in winter 2007/8, when the observed index was +1.6."

Note...however...last year/s prediction (-0.05) was essentially the same as this year/s and last year/s observed NAO was +1.6.
Move along. Not much skill here. At least not in the past few years.

The Northeast Weather Snowfall Forecast Contest (NEWxSFC) is celebrating its 10th anniversary this winter. The Contest began during the '99/'00 season on USENET/s ne.weather news-group. It/s the longest continuously held snowfall forecasting contest for the NE CONUS on the Internet.

Special prizes will be awarded to the top Forecasters this year to commemorate the event. Sincere thanks go to Jack @ StormVista for his generous donation of StormVista GOLD and continued support to the NEWxSFC.

There are usually 8 - 10 contest-worthy storms each winter. You can win one (1) month of access to StormVista GOLD if you make the best forecast for any one of these storms.

Place 1st in the end-of-season standings and you/ll win the two-volume...hard-bound set "Northeast Snowstorms" (Kocin/Uccellini) and three (3) months access to StormVista GOLD.

Place 2nd and you win two (2) months access to StormVista GOLD.

Place 3rd and you win one (1) month access to StormVista GOLD.

As always...there are no fees...costs...or annoying requests for personal information of any kind to enter the Contest. Please visit the web site for further details.
