Wettest spring on record for Peoria & Galesburg

A very active spring weather pattern has brought repeated heavy rainfall to portions of central Illinois.  For the period of "meteorological spring" defined as the months of March, April, and May, both Peoria and Galesburg have established a new all time record wet spring.  Rain totals for these three months were nearly 200% of normal.

Peoria's cumulative March through May rain total of 19.91" for 2009 surpassed the old record of 18.64" set in 1927.  In Galesburg, the new record of 20.35" crushed the previous high of 17.73" from 1898.  Both sites have a long historical record, with data at Peoria beginning in 1883, and Galesburg in 1895.  

The Peoria observation site is currently located at the Peoria International Airport.  Click here for a Peoria weather station history.  The Galesburg observation site has been maintained by a number of volunteer Cooperative Weather Observers through its 114 year history.  Data are considered preliminary and subject to revision until certified by the National Climatic Data Center.
