http://www.artberman.com/blog/ : ""History suggests that natural gas prices will almost certainly reach $4.00 to $4.25 during the coming winter and that much higher prices are possible." - Art Berman October 15, 2018
Lots of good charts to back up his opinion at the link above.
Art points out and I agree with 100% that demand for gas in the winter is going up each year because we are exporting more gas and more areas now rely on gas fired power plants for electricity. Each year, dozens of coal fired power plants are replaced by natural gas fired power plants. Even if we have a mild winter, it is a good bet that natural gas storage is going to be drained this by April, 2019.
BTW there are two new LNG export facilities coming on-line early in 2019.
