this weeks storage poll is for week ending 1/11 and reported by EIA on 1/17.
observation:
total degree demand was warmer than average but colder than last years historic warmth during the same week.
the decreased week over week temperature change resulted in around 85bcf less demand for residential and commercial heating use from the week prior.
total supply was down slightly from the week earlier by around 1.3bcf.
colder temperatures slowed production over the Rockies regions as overnight lows were below zero.
last weeks -201 report appears to have included some silent revisions from TCO and Dominion storage of around -8bcf. (Bear Creek -770.4MMcf; Dominion -5758.8MMcf; Eminence-185.8MMcf; TCO -1236.4MMcf)
