The folks who keep track of these things expect today’s record-cold polar vortex in the Midwest and northeast (coldest temps in more than a generation, hey, what was that about global warming?) will create the highest demand/usage of natural gas for a single day–ever. Prognosticators also predict a “freeze-off” in the Marcellus/Utica, causing a temporary 1 Bcf/d decrease in production.
