If predictions of another cold winter in the United States, especially in the Midwest and Northeast, are true, then United States Natural Gas (NYSE: UNG) should start rising in price.

Reports of an heavy snow in Siberia could be a major indicator.

From snow in Siberia, cold air blows into the United States.  That takes the temperatures much lower.  This increases the demand for natural gas as more is needed to heat homes and offices.  Natural gas powers many utility plants in America.  When that takes place, the share price for United States Natural Gas, the exchange traded fund for natural gas, should rise.

That has certainly not been the case in recent market action.

United States Natural Gas is down for the last week, month, quarter, and six months of market action (chart below).  For 2014, it has fallen by nearly 5 percent.  In just the last week it has dropped by almost 6 percent.

This fall in the share price of United States Natural Gas could make for even larger gains.

It is presently trading for around $19.70.  The 52-week high is $27.89.  Obviously, there is tremendous upside to United States Natural Gas.

Overall, the demand for natural gas should continue to rise.  It is cheaper than oil and much cleaner than coal.

At present, slumping economic growth around the world has the price of United States Natural Gas and other energy assets down.  There are no forms of alternative energy that are close to meeting the needs of the mass market.

But cold weather in the United States should be the first event to take the share price higher for United States Natural Gas and other securities in the sector.  After that, it will be economic growth around the world.  From those and other factors, the long term outlook for United States Natural Gas should be positive.
