Forecasts for this upcoming fall and winter are changing rapidly due to the building La Nina event in the equatorial Pacific. Based on current sea surface temperatures and model projections, this event is expected to be one of the strongest events measured since the 1950s. Current models indicate much of the Pacific Northwest, northern Rockies, and northern Plains should experience below normal temperatures and above normal moisture.


Closer to home, Nebraska is projected to lie on the southern fringe of the colder and wetter than normal area. It also is projected to lie on the northern fringe of the above normal temperature and below normal precipitation area indicated for the southern U.S. If this verifies, we will lie in the battle zone of air masses and temperature swings over short time frames (one week or less) can be expected, with an occasional ice and/or snow storm.
