Dragon: EIA NatGas price forecasts are revised monthly, not weekly. The EIA releases a widely watched weekly inventory report each Thursday morning at 10:30am. The inventory injections/withdrawls vary a lot depending on heating or cooling demand for the prior week which is weather dependent.
I think the EIA 2015 and 2016 price forecasts are reasonable. They've been coming down steadily for several months due to bearish fundamentals. The past 12 months have seen record storage injections despite a very cold winter.
