Spot natural gas for weekend and Monday delivery was markedly higher on average in Friday's trading, but there was a wide variation of prices in that mix.

Metropolitan areas such as New York, Boston, Philadelphia and Chicago all reported hefty gains, some in the double-digit dollar category, but market points in producing regions generally lost a quarter or more. Philadelphia and Boston led the day's advance, but the New York area was not far behind. Futures rocketed higher, posting the highest close in three and a half years as traders continue to factor in persistent cold and uncertainty regarding season ending supplies. At the close, February had added 45.2 cents to $5.182 and March was up 41.9 cents to $4.998. March crude oil fell 68 cents to $96.64.

New England prices surged for weekend and Monday packages as buyers uncertain of weekend needs in light of extreme weather conditions locked in supplies. According to the National Weather Service in Southeast Massachusetts, conditions would be "cold and dry towards Midnight...[with] temperatures moderating warmer thereafter. Disturbance for Saturday with light snow and strong south-southwest winds. Another surge of Artic air to the rear. A fast-moving Alberta clipper brings light snow Sunday night and Monday followed by more chilly air. High pressure brings dry weather for much of the week."

Stretching further out Joe Bastardi of WeatherBELL Analytics sees, "The severe cold shot next week is every bit the crisis of cold as advertised. The problem after that is the threat of another major shot, almost December style, coming out of the West with more penetration south in the 11-15 day period. I am watching the SOI [Southern Oscillation Index] because a sudden drop would probably let loose that hound. Remember, before the December outbreak there was a drop going on. As I said, that can be like a cattle prod to the pattern. There has been virtually no MJO [Madden Julian Oscillation] connection to the pattern as we are in what is normally a warm phase, as the north Pacific warm pool runs rampant in its influence. However, changes where water is 80 degrees will trump changes where it is in the 40s, even with the kind of anomaly there."

Quotes at the Algonquin Citygates for weekend and Monday delivery rose $9.23 to $43.40, and gas on Iroquois Waddington deliveries rose $9.47 to $35.90. On Tennessee Zone 6 200 L packages changed hands at $42.92, up $8.80.

Gains at New York and Philadelphia points went toe-to-toe with those in New England. Gas on Tetco M-3 gained a stout $11.62 to $46.87, and gas bound for New York City on Transco Zone 6 gained $7.26 to $56.06. Farther west, gas on Transco Leidy eased 21 cents to $4.19, and on Dominion weekend and Monday parcels rose 18 cents to $5.41.

Buyers looked to be more concerned with the bigger weather picture as temperatures in New England were expected to rise into the weekend but drop by Tuesday. Forecaster predicted the high in Boston Friday of 18 would rise to 38 Saturday, make it to 36 on Monday before sliding to 18 again on Tuesday. Hartford, CT's 25 high on Friday was anticipated to make it to 31 Saturday, 34 on Monday and drop to 18 on Tuesday. The normal high in Boston this time of year is 36 and Hartford is 35.

Midwest points also scored gains. On Alliance, weekend and Monday gas rose $2.60 to $9.43, and packages at the Chicago Citygates rose a hefty $4.15 to $10.68 after trading as high as $20. At Northern Natural Ventura gas was seen at $9.91, up $2.97, and at Demarcation weekend and Monday gas came in at $5.88, up 38 cents.

Locations in producing regions and otherwise removed from the weather events slashing through the Midwest and East saw prices slip. Gas at the Henry Hub over the weekend and Monday fell 37 cents to $5.19, and gas at El Paso non-Bondad dropped 14 cents to $4.74. At Opal, weekend and Monday packages lost 14 cents to $4.89, and at the SoCal Border gas was seen at $4.89, down 16 cents.

Well freeze-offs appear to be less of a problem. In a report, industry consultant Genscape said Friday's freeze-offs totaled 932 MMcf, down from Thursday's 1,513 MMcf and Wednesday's 964 MMcf. Friday's hardest-hit areas were NE Pennsylvania at 307 MMcf, West Virginia 205 MMcf and Ohio at 123 MMcf.

Futures traders are at a loss for words. "I don't know where we go from here. It's just one of those calls since no one wants to pick a top and no one is making any offers, "said a New York floor trader. "I don't know if we'll get some more cold forecasts, but $5.75 is not out of reach."

A lot of market angst is centered around how low can season-ending storage go before the arduous process of refilling begins. One school of thought has it that U.S. natural gas storage could fall to 1.2 Tcf by the end of withdrawal season. The last time ending inventories reached that level was March 2008 at 1,266 Bcf. Spot futures March 31, 2008 settled at $10.101.

Stephen Smith, who shares storage and pricing insight through Stephen Smith Energy Associates, talked with NGI on Friday about a new storage model he ran earlier in the day. The numbers, like the weather, "keep changing quickly," he said.

"Basically, we thought that this polar vortex business would last through the end of January," Smith said. The National Weather Service [NWS] "not too long ago was predicting that February would be milder than normal...But other forecasters now say February is looking colder than normal." (see related story).

Analysts see increased risk going into the weekend as temperature forecasts can often shift dramatically. "The market's ability to snap back up into fresh territory overnight following [Thursday's] post-EIA pullback of as much as 26 cents attests to the voracity of this weather induced price spike," said Jim Ritterbusch of Ritterbusch and Associates in a morning note to clients. "But with the market virtually attaining the psychologically important $5 mark, maintaining buying interest today could be challenged by pre-weekend profit-taking that will force some wide price swings.

"Temperature forecasts can change dramatically over a weekend, as has been seen on several occasions in recent months, and as a result existing longs will be looking for reasons to accept at least partial profits in today's trade. We are viewing yesterday's lows as near-term support and would not rule out a quick return to this area within the next couple of sessions."

Analysts at Genscape see a fundamental shift in New England demand. "During the recent cold snap, Algonquin Citygate prices blew out to last winter's levels. The magnitude of the past two winters' blowouts are much greater than that seen in the previous four winters. While it was cold (record cold in fact) the temperature deviations during the recent cold spike weren't necessarily extreme. The same is true with temperatures during last winter's price spikes; while low they didn't reach unprecedented levels. However, we have observed the increase in citygate demand in relations to temperature," the company said in a morning report.

Algonquin Citygate prices are certainly behaving differently. The gains in prices do not seem correlative to the admittedly much colder temperatures. According to NGI data, Algonquin Citygates dropped more than $40 Thursday to $34.17, but that followed a posting Wednesday of $78.30.

"Despite -- or because of -- this shift, however, gas prices are reacting differently this and last winter than versus the same temperature and demand levels of previous winters. The New England market is paying progressively higher prices for gas at the same temperature and demand levels as previous years. This echoes our statements earlier in the winter that LDCs are not sensitive to prices and instead more focused on reliability of natural gas deliveries."
