The NWS Climate Prediction Center released today their outlook for March and beyond. There is still a 50-60 percent chance of El Niño showing up in the next few months but likely to be both weak and short-lived. I do not think it will be a major player in 2015.
First of all for March, Illinois and the Great Lakes region have an increased chance of below-average temperatures. That is no real surprise given the cold weather of recent weeks and expected below-average temperatures in the 14 day outlooks. We have equal chances (EC) of above, below, and near-average precipitation. Click to enlarge maps.
After an expected colder than average March, we see a reverse pattern in Illinois and the Great Lakes region with an increased chance of above-average temperatures.
There is not much to report for the heart of this summer in Illinois. We have EC for both temperature and precipitation.
