RE:RE:Freeze offsFreezes may take place in Marcellus, temperatures in Pittsburg are forecast below -20C for a few nights in a row next week. May affect production and delivery to Michigan and Dawn hub. Even without it, the populous Chicago will be hit hard lifting demand for natural gas. Should benefit Canadian producers selling to Midwest hubs. As long as there is no change in the weather forecast this weekend, next week will be very exiting.
