The title of this post comes from a comment left yesterday on the WROC News 8 Weather blog and a post done by our Chief Meteorologist, Scott Hetsko, “BEATING A DEAD HORSE” on how yet another storm system will miss Western New York. This comment struck a chord with me and I think it really sums up the frustration felt by many who visit our blog and love winter.
Here are the facts, as I know them. Here in Rochester we have seen 62.2″ of snow for the season. At least 90% of that is from lake effect. It’s tough to quantify just how much of our current snowfall has come from synoptic but it’s safe to say that less than 10 inches of our 62.2″ is from snow outside of lake effect. When you consider that 50% to maybe 55% of our snow (on average) comes from lake effect with the other 45% to 50% coming from snow storms, to be above normal for the season and getting only 10% from synoptic that is impressive, but not the scenario many of you want to see.
This morning, I talked with one of the Buffalo National Weather Service Meteorologist Steve Mclaughlin, he provided me with some of the data above. Since I’ve only been here for 2 winters, I also wanted to get a better climatological understanding of where all of our snow comes from and see if I could pick their brains a little to see when we might start to see a change in the pattern and get a good storm up here in Western New York.
This brings me to another comment left by another frustrated visitor to our blog who said this, “are there ANY scraps for us to hold on to at this point that give us hope that a big one is still coming….based on data?” Unfortunately, the best data we have at this point is climatology, and historically speaking, our best chance to get a big synoptic storm is from late February into early March. If you are looking for any big storms for the next two weeks it still doesn’t look like it is in our favor. In fact, there are some forecasts that I have seen that push the southern jet even a little farther south and some of these storms just pass through the southeastern US and out to see.
We all feel your frustration here in the weather office. We want to have our turn at a big snow storm, but we need realize how fortunate we are that we have any snow at all, and to be above normal for the season at this point.
The saying goes “misery loves company” and if you go and check out AccuWeather.com’s Jesse Farrell’s Weather Matrix blog he did a post on other northeastern locations that are fairing worst than we are when it comes to their seasonal snow amounts.

That’s right Woodchuck Chuckers, it’s GROUNDHOG DAY!!! This is one of my favorite holidays. It’s just fun. I also love winter, so I am not too disappointed that Punxsutawney Phil saw his shadow which means 6 more weeks of winter.
Groundhog Day grew out of what had essentially been a German superstition. German settlers brought with them the idea that if a hibernating animal casts a shadow Feb. 2 — the Christian holiday of Candlemas — winter will last another six weeks. If no shadow is seen, legend says spring will come early.
It’s pretty common for ‘ol Punxsutawney Phil to see his shadow. Of his 113 predictions, Phil has seen his shadow 99 times or 87% of the time with only 14 times he has predicted an early spring.
As far as Phil’s accuracy, if you ask the Inner Circle who takes care of Phil he is right 100% of the time but according to StormFax Weather Almanac, and records kept since 1887, Phil is right only 39% of the time.
Thanks to the 1993 movie staring Bill Murray, Punxsutawney Phil may be the best known of the Groundhogs but he isn’t the only furry forecaster making predictions on February 2nd. In fact, there are several across the United States and Canada and one right here in Western New York. Here is a short list of other known Groundhogs and their predictions for 2010.
- Dunkirk Dave (Dunkirk, NY) – Saw no Shadow, an early Spring
- Wiarton Willie (South Bruce Peninsula, Ontario CA) – Saw his Shadow, 6 more weeks of winter
- Staten Island Chuck – (Staten Island, NY) – Saw no Shadow, an early Spring
- Shubenacadie Sam (Nova Scotia CA) – Saw his Shadow, 6 more weeks of winter
Of course this is a very small list of all the Groundhog celebrations across North America, you can see more here at “Groundhog Central”
Of course as far as my official forecast for spring is that it will arrive March 20th but we all know here in Western New York that spring never arrives then but usually around mid April. Have a great day everyone.

For just a couple of minutes every February second, in front of a large crowd, television lights and cameras Phil is held by the mayor for all to see then his declaration is read and he goes back to living the rock-star life any groundhog could wish for. But based on a letter and blog post written by PETA (People for the Ethical Treatment of Animals) this is not acceptable treatment of a groundhog.
“To most people, Groundhog Day—celebrated annually on February 2—is a welcome midwinter diversion, but Punxsutawney Phil is forced to be on display year round at the local library and is denied the ability to prepare for and enter yearly hibernation. These normally shy animals—who are constantly on alert when they are out of their burrows—become stressed when they are exposed to large, screaming crowds; flashing lights from perhaps hundreds of cameras; and human handling.”
PETA’s solution, replace Phil with a robot, more specifically an animatronic groundhog. Personally, I feel and think that PETA is really just looking for something at this point. In many of the places I have lived, the groundhog is very common in the wild. Because of this I’ve seen lots of these wild groundhogs succumb to being roadkill on the side of the road.
As I mentioned above, Phil lives the life of a rock-star, compared to other groundhogs, and he lives in a special, climate-controlled house, gnaws on the finest groundhog cuisine and receives cutting-edge rodent health care.
What do you think? Do you agree with PETA on this or do you feel they are just looking for something to protest?

Tomorrow is February 2nd and it’s Groundhog day, and it’s time for my Groundhog Day Eve preview. Here are some facts about Punxsutawney Phil and Groundhog Day you should know.
WHO IS PHIL?:Punxsutawney Phil has been making weather prognostications every Feb. 2 in Punxsutawney, Pa., since 1886.
THE ORIGINS: Groundhog Day grew out of what had essentially been a German superstition. German settlers brought with them the idea that if a hibernating animal casts a shadow Feb. 2 — the Christian holiday of Candlemas — winter will last another six weeks. If no shadow is seen, legend says spring will come early.
WHERE IT HAPPENS: Punxsutawney is a town of about 6,100 people located about 65 miles northeast of Pittsburgh.
MORE INFORMATION: http://www.groundhog.org/ and you can watch the live forecast here: VisitPA.com
Punxsutawney Phil may be the most famous of the groundhogs but he’s not the only furry forecaster around. Here in Western New York we have two groundhog traditions. Dunkirk Dave and Ridge Lea Larry.

(this is from the post I did this morning on the
News 8 Weather Blog for WROC-TV in Rochester, NY)
I decided to use the quiet weather pattern and sunshine to open this mornings post up to you the commenters and answer some of the weather question you may have on your mind. So feel free to post your question below, you comment will be emailed to the weather team and we will come back and answer it.
The first comments I want to address occurred yesterday in Scott’s Thursday Afternoon post, “SIGNS OF WINTER RETURNING” regarding how much of this current pattern or the pattern we’ve seen so far has been related to El Nino.
Although this is an El Nino winter, and you can attribute the storminess in California this past week to El Nino, it’s not the only player that has or will continue to impact our winter.
The first 2 weeks of January when we were seeing all that cold, it wasn’t El Nino but it was the North Atlantic Oscillation (NAO). The NAO is a climate pattern in the North Atlantic Ocean of fluctuations in the difference of sea-level pressure between the Icelandic Low and the Azores High. Through east-west oscillation motions of the Icelandic Low and the Azores High,the NAO controls the strength and direction of westerly winds and storm tracks across the North Atlantic. When there is a large difference in pressure between Iceland and the Azores (positive NAO) westerly winds increase and Europe will get a mild and wet winter. Here in the United State, a positive NAO will cause the Icelandic Low to bring a stronger south-westerly flow of air over the eastern US, preventing Arctic air from plunging south. During this January thaw we’ve seen over the last week and a half the NAO trended to the positive side. As you can see in the graphic below. (Click to enlarge)

If the difference in pressure between Iceland and the Azores is small (negative NAO), westerly winds decrease and are suppressed, allowing Arctic air to spill southwards into eastern North America more readily. Negative NAO winters tend to bring cold winters to Europe, and the prevailing storm track moves south towards the Mediterranean Sea. This brings increased storm activity and rainfall to southern Europe and North Africa. As you can see in the graphic above, the NAO was very negative as we endured those very cold winter temperatures.
The areas in black are observed value of the NAO and the red lines represent a suite of models’ forecast on how the NAO will change in the coming days and weeks. Towards the end of January the start of February, we start to see a good portion of the models begin to trend the NAO negative to reinforce our forecast that very cold air will return into early February.
When talking about the cold weather we had and will see again in the coming week you also can’t ignore the Arctic Oscillation (AO). The AO refers to opposing atmospheric pressure patterns in northern middle and high latitudes, it’s also a pretty good source on of how much cold air is likely to escape from the North Pole.

For most of the past century, the Arctic Oscillation alternated between its positive and negative phases. But over the last 3 decades, going back to the 1970s, it appeared the AO was stuck in positive phase, this created strong westerly winds that whipped around the Arctic,and effectively preventing much of the Arctic air from spilling south into the eastern U.S. and much of Europe.

The above graphic, like the chart I showed from the NAO, shows the observed value in black and the forecasted potential in red from several different computer models. During our cold outbreak in January the AO was at it’s lowest level in a very long time. As we started to see our January Thaw the AO began to turn positive and now you see that some of the models and a good portion of them start to trend negative as we head into February.
I hope that put some of the factors that impact our winter into perspective. Feel free to ask any question and we will try to get back with you and maybe do a specific blog post on your question or topic.
