Updated January to March 90 Day Forecast

21 Dec 2016, 10:20 am

The Climate Prediction Center (CPC) recently issued their 90 day forecast covering January to March. Warmer and drier than normal conditions are expected across the South, with cooler and wetter than average weather in the Northwest and Upper Midwest.

The CPC says weak a La Nina continues across the Pacific Ocean, with cooler than normal water temperatures found over the last month. The La Nina is expected to diminish sometime in January. Water temperatures are expected to become neutral as we move into February. The overall basis for the forecast will be to lean towards a typical La Nina forecast, but trend back as Pacific Ocean sea surface temperatures cool.

As discussed in a previous article, La Nina occurs when the waters of the Pacific Ocean show a general trend of cooling, the opposite of an El Nino. During La Nina periods, the Jet Stream is less active in the Southern U.S. This usually leads to less storms systems and below average precipitation. Cooler than normal weather typically occurs across the northern tier of the country and occasionally wetter periods as well. You can read more about our current La Nina here.
