Prompt prices hit near month highs Wednesday on the UK's NBP gas trading hub with forecasts of colder temperatures the key driver, market sources said.
The within-day contract was valued at 67.60 pence/therm at 1200 GMT, up 3.30 p/th from where it closed Tuesday, and day-ahead gas rose 2.20 p/th to 67.80 p/th.
The values were the highest since December 12.
"Demand has risen this morning with the drop in temperatures," a market analyst said. "Storage withdrawals from Easington Rough are at full capacity of 43 million cubic meters/day, and are set to continue for the short-term as temperatures are due to fall below average by the end of the week."
Temperatures in London and Glasgow were both above norms by 1 degree Celsius Wednesday, CustomWeather data showed, but are expected to be in line with norms Thursday and London is forecast to fall to 6 C below at the weekend and fall further into the new week.
At midday, National Grid had forecast demand pegged at 279 million cu m, and the system was operating 7 million cu m short.
