The National Oceanic and Atmospheric Administration, or NOAA, is out with a long-term winter forecast for the Valley.

The seasonal outlook is all dependent on the development of a La Niña pattern in the next several weeks. La Niña is the phenomenon where cooler water in the Pacific Ocean sloshes east toward the western edges of Central and South America. This cool pool of sea water impacts air currents and weather pattern across North America.

Right now there is a 60% chance a La Niña pattern will develop which is forecast to bring a warm and dry winter to the Rio Grande Valley with above normal temperatures and below normal rainfall through January.
