MENDOTA - Ice and snow arrived throughout the area to start the new year following a warmer and drier December for most of the state. Total precipitation for December ranged from just under 3 inches in northwest Illinois to just over 1 inch in much of central and southern Illinois. The entire southern two-thirds of Illinois was drier than average in December.
Illinois State Climatologist Trent Ford at the University of Illinois’ Illinois State Water Survey says after the active start to January, the Climate Prediction Center’s 8- to 14-day outlooks indicate the highest odds of a change to warmer and drier than normal conditions across the state into the second week of January.
The outlooks for the entire month of January lean toward warmer and wetter than normal conditions, suggesting a change to more active winter weather around the middle of the month.
As La Niña conditions are expected to persist into early spring, forecasts from the North American Multi-model Ensemble for February through April favor warmer and wetter conditions through the winter-spring transition.
