Five more weeks of winter?
Posted by: Dr. Jeff Masters, 3:33 PM GMT on February 02, 2006 +0
Punxsutawney Phil, the fearless rodent prognosticator of Punxsutawney, Pennsylvania, saw his shadow this morning. According to tradition, we can expect six more weeks of winter are on tap for the United States.

Your fearful human forecaster predicts about five more weeks of winter--including some very harsh winter weather in mid-February. This forecast is based on long range model forecasts from the GFS model, plus observations of a "resonance" in Earth's climate system called the North Atlantic Oscillation (NAO) that I discussed two weeks ago. The NAO has just switched from its positive phase to its negative phase. The negative phase is typically associated with a jet stream pattern that brings cold Arctic air to the Eastern U.S., and that is the pattern we saw in the five week period from November 16 - December 23, when cold air gripped much of the Eastern U.S. The positive phase of the NAO is associated with a northward retreat of the jet stream into Canada, and usually brings much above normal temperatures to the eastern half of the U.S. The positive phase of the NAO dominted during the five-week period from December 23 - February 2, and record warm winter conditions were experienced across most of the U.S. during these past five weeks.


Figure 1. The North Atlantic Oscillation for Nov. 1 2005 - Feb. 2, 2006. The postive phase of the NAO has been associated with warmer than average temperatures at Detroit and most of the eastern half of the U.S., while the negative phase has been associated with cooler than average temperatures. Image credit: NOAA Climate Prediction Center.

Well, the NAO has just flipped back into it's negative phase (Figure 1), and I anticipate that given the five-week periodicity in the oscillation we've been seeing the past few months, we're in for a five-week period of colder than normal weather across most of the U.S. These below-average temperatures should ease up in early March when the NAO flips back into its positive mode. Long range temperature outlooks from the GFS model show the first Arctic air of the year invading the U.S. after Super Sunday, peaking in mid-February. I expect below-zero temperatures will affect most of the Midwest and Northeast by mid-February, with temperatures colder than -20 F in Minnesota. The Siberian Express is on its way!

The town has placed these statues of groundhogs all over. They are about five feet standing and all of them are unique, like this one.

Thanks for the update. This should indeed please those wishing for winters return. However, I worry for those with high heating bills.

Short term models aren't looking as cold as even 12-24 hours ago. There will be a pretty good cold shot to the mid-west and N. East starting this weeked; however, it doesn't look as if it's going it get absolutly frigid or not.

Only the NOGAPS says temps of 260 degree Kelvin and below(8 degrees F) will reach all the way down to the Kentucky/Tennessee and Viginia N. Carlonina borders by into next weekend. The rest of the models don't have the cold going as far south, but they all say by this weekend that we won't be enjoying the mild weather anymore.

I don't trust the groundhog at all. Stranger things have happened...and the more weeks of winter is all relative based on location.

It is all fun and many of us that celebrate groundhogs day for other reasons. I “unofficially” look at today as the first day of spring. Days are noticeably getting longer, I can walk around the lake before it gets dark, birds are signing, animals are pairing up, and things are starting to become better! I make it through the winter knowing the warblers and butterflies will be back in the spring. Either Mr. Groundhog is right or wrong, it is still a fun day to have hope for spring!
5. HurricaneMyles 4:38 PM GMT on February 02, 2006    
Crazy, I dont think the groundhog has ever said Spring is here. I've never heard the news say the groundhog didnt see its shadow. It always says thier's 6 week's of winter, and this time he's actually right cuz winter is about to make a return.

Wow, we're in for a cold February! That should be enough for speculators to take gas above $4/ gallon!!

Still not going to be cold enough to close up the lakes in Southern Michigan. May ice over but not enought to stand on. Dissapointed Ice Fishermen for sure.

Ok globalize, let's not overdo it here. It could, and I stress,

Glad I'm not an ice fisherman, just a regular one =)
But anyways, I doubt gas will go up to $4/gallon just because of some cold weather. We'll see, but I dont think its too likely. You obviously disagree, globalize.

Oops, that what happened when all the weird stuff happened to my comp. Disregard the choppy post, I was changing this around and something screwy happened.

U.S. Average is $2.34 a gallon at the moment. I will say it will go to $2.69 a gallon by 2/16 and peak at $2.89 by the end of the month. Don't think you will see it get back above $3 until closer to Memorial Day and it will probably bounce around either side of $3 all summer provide there are no major supply problems (Hurricane's,Iran,etc...).

A few potshots then I reply to the good doctor's new post

Globalize - gas will be going up period. Cold weather doesn't has as much effect on gas as oil (since their isn't too many homes that heat with gasoline aka car fuel). Now international events on the other hand do. Since its a sellers market right now because Business 101, demand is high, supply is tight and any little effect causes a mad rush of buying.

As far as high heating prices we could always ask Iran for some uraium to keep warm (LOL).

Seriously if what the good Doctor is preaching comes to past then us folks around the lakes may be in for some fun since usually the lakes are partial to full frozen this time of year. They are not (maybe I can sneak up to Lake Ontario today before sunset and snap a couple of shots, for those not in the know I live about 2 miles from the southern shore of Lake Ontario). Being the case if a good strong front came down I wouldn't be surpised to see a repeat of a blizzard we had a couple of years back where it snowed 22 inches in under 10 hours, then another 20 inches 2 days after.

Actually, cold weather usually depresses gasoline prices because people drive less in the cold.

My natural gas bill was $170 even with the warmest January on record in KC! Sheesh, and last January I used a lot more but paid less.

hey oriondarkwood, I'm about 15 K from the western end of Lake Ontario, and yes all it will take is cold air and a good strong wind off the lake to bury those on the downwind side...

rwdobson,

True, but that is usually offset by the drop in supply as production shifts from gasoline to home heating oil.

16. oriondarkwood 6:06 PM GMT on February 02, 2006    
Snowboy,

Since yer talking clicks aka kilometers instead of miles (for those not in the know 1 kilometer = 0.621371192 miles, thanks to Google, I live in the Toronto area for 2 years snowboy). And assumeing you talking exterme western in (ie Burlington Bay area) that would put you around the St. Geroge area.

Do I get a cigar (LOL)?

Yea they is a bridge near my house (look up Webster, NY on the map and go west you see a Irondequoit Bay, there is a bridge on expressway 104), this is a nasty bridge to cross in a blizzard, the wind is funneled in along with everything else. My poor Nissian gets batted around like a hockey puck on that bridge during a blizzard.

Anyone taken a look at Boloeste lately? It's a hurricane now and incredibly small. The whole storm center CDO is only about 140 miles across. I think Katrina had hurricane force winds out 140 miles each side at one time!

Winter, what is this winter all of you speak of?

:P

Greetings to all from Tucson ;)
20. rwdobson 8:11 PM GMT on February 02, 2006    
...and the shift to home heating oil is partly balanced by the fact that refineries don't have to make as many different blends of gas as they do during ozone season. it's a complicated business.

That is is. I have a friend who is a project engineer for one of the major refiners in the US. It's incredibly complex. Most of us think in terms of oil and gas, but there are countless variations of each, not to mention all the volatile chemical by products, some of which are used as inputs into other products.
22. Gatorboy 8:20 PM GMT on February 02, 2006    
so how is Snowshow west virgina gonna be, more snow around febeurary 17th?
23. oriondarkwood 8:21 PM GMT on February 02, 2006

If global warming was true in the first place, it wouldnt happen in 5 years for climate change, and second of all this earth of ours have been around for billons of years, this could be a natural thing, i wont worry about this.
30. buckeyefan1 8:30 PM GMT on February 02, 2006
