NOAA's Climate Prediction Center has issued their outlook for January to March 2019, which still indicates patterns of a weak El Nino. Warmer than average temperatures are predicted across the West and Northern Plains. Colder than normal weather is predicted for the Tennessee Valley. From the Southeast to the Southwest, wetter than average weather is in the forecast. In the Ohio Valley and Pacific Northwest, below normal precipitation is predicted.
The drought forecast for the start of 2019 continues to show improvement across California and the Rockies. With the drier than normal forecast for the Northwest, drought conditions are likely to develop over that region.
The extensively discussed El Nino is underway
in the Pacific Ocean, but the atmosphere has yet to respond. Observed sea surface temperatures in the Pacific are warmer than normal as expected, with computer models expecting this to continue. Right now, the overall global pattern resembles neutral conditions. Based on the latest observations and model forecasts, the CPC still indicates
a greater than 80 percent chance for El Nino
from January to March and 70 percent that it persists through May.
