Latest Monthly and Seasonal Forecasts

Last Updated on 1/21/2012

The outlook for the month of February from the Climate Prediction Center (CPC) is calling for greater chances of above normal temperatures (Fig. 1) over much of Missouri and Illinois.  This outlook indicates that the warmer than normal conditions that we have had so far this winter will probably continue.   The precipitation outlook (Fig. 2) also favors slighty higher chances for above normal precipitation with the best chances of above normal precipitation centered over the Ohio River Valley.  These chances reflect conditions that occur with the ongoing weak to moderate La Nina, which is when sea surface temperatures along the equator in the Pacific Ocean are cooler than normal.  It is expected that the La Nina will diminish between March and May.  The three month outlook for February, March and April are similiar, favoring slightly higher chances of both temperature (Fig. 3) and precipitation (Fig. 4) over much of the area.   More information about La Nina and these outlooks can be found on the CPC website at:  http://www.cpc.noaa.gov

Local Outlook

The local three month temperature outlook downscales the national temperature and precipitation outlooks for 40 sites in the St. Louis County Warning Area.   Each site gives the specific chances for above, below, and near normal temperatures for each three month period over the next 13 months. 

Drought

Drought conditions are expected to persist or worsen over the southern part of the United States.  The above normal precipitation outlook should keep drought conditions out of our area through at least the end of April.
