PEORIA (HEART OF ILLINOIS ABC) - Meteorological Spring consists of the months March, April, and May.

Historically, the average daily spring temperature has risen 3 degrees since 1970. If you’re a fan of warmer temperatures, you may be in luck.

The Climate Prediction Center forecasts that over the next three months we have a 40-50% chance at above average temperatures. However, they also predict a 40-50% chance for above average precipitation too.

The National Weather Service issues a Spring Flood and Severe Weather outlook. Several parts of the Illinois river are likely to have minor to moderate flooding, but nothing major.

Darrin Hansing, a Service Hydrologist for National Weather Service, “Overall we’re expecting near normal likelihood for flooding across much of central Illinois. The exception of that is across portions of the Illinois River, primarily from Peoria downstream to Havana and Beardstown, we’re expecting above normal likelihood primarily minor to moderate flooding.”

As far as severe weather goes, we are 44% more likely to have an active severe weather season following a La Nina winter. La Nina is a type of atmospheric circulation that we typically see bring colder and wetter winters to Illinois, which we saw take place this February.

Severe weather is hard to predict in advance, but a connection can be made between the above normal precipitation outlook and severe weather ---that is flooding.

Hansing added, “Not just tornadoes, and severe thunderstorms, as far as being a threat. We have springtime flooding, and flooding really anytime of the year is an important factor to consider as far as threats go.”

For now, what we know* about March is that the average high by the end of the month is 58 degrees… We can still expect snow up to 3.3 inches, and we will gain about an hour and 20 mins of daylight by the end of the month.
