Updated February Outlook – Cold & Wet North, Warm & Dry South and West

1 Feb 2018, 3:26 pm

The updated February forecast was issued Wednesday from NOAA’s Climate Prediction Center (CPC). There are only a few minor changed from the forecast issued earlier on January 18th. Cooler and wetter than average weather is still expected over most of the northern tier of the nation. Drier and warmer than normal weather remains in the forecast for the south, but has been expanded westward to include the Southwest.

La Nina conditions are still being observed in the Pacific Ocean and the CPC expects the atmosphere to continue in a La Nina pattern. The forecast update was based heavily on weather trends normally seen during a La Nina, along with model projections.

La Nina (translated from Spanish as “little girl”) is a natural ocean-atmospheric phenomenon marked by cooler-than-average sea surface temperatures in the central Pacific Ocean near the equator. It’s the opposite of El Nino (“little boy”), which is when warmer than normal water temperatures are observed.
