The Climate Prediction Center (CPC) recently issued its updated 90 Day outlook covering the period of March to May. It calls for a large area of above average temperatures, extending from the Southwest through the Plains and into the Northeast. Wetter than average conditions are expected from the Northwest to the Upper Midwest, with below normal precipitation in the Southwest.
No La Nina or El Nino (ENSO) conditions are expected in the Pacific Ocean. The CPC has observed an end to the recent La Nina, which brought colder than normal water temperatures to portions of the Pacific Ocean. Neutral or near normal temperatures are being found now.
The forecast says “recent oceanic and atmospheric observations show that ENSO-neutral conditions have returned to the equatorial Pacific Ocean. The official CPC ENSO forecast favors ENSO-neutral conditions to persist at least through the Boreal Spring (Northern Hemisphere Spring), with significant uncertainty in the phase of ENSO beyond that time.”
Forecast model predictions, sea surface temperature expectations, and historical trends were the main influences considered for the outlook.
