Natural gas rose on forecasts for more cold weather and heating demand over the next two weeks than previously expected. A frigid Arctic blast continues across much of the US east of the Rockies this morning w/lows of -0s to 20s. The cold front will bring rain and snow into the East today, with lows for major Northeast cities dropping into the 10s and 20s the next few nights to aid very strong national demand. A reinforcing cold shot is expected across the Northeast Fri-Sun. The West will be mostly mild and dry w/highs of 50s to 80s, coolest Northwest. Much of the northern, central, southern, and eastern US will warm early next week to near or warmer than normal. Overall, VERY HIGH demand into the coming weekend.
