We are about a week away from the start of meteorological summer. After a cool, wet spring it looks like summer could start off steamy. So far this has been the 2nd wettest spring on record and nearly 60% of days have recorded below average temperatures. We may be about to experience more "weather whiplash". Both the 6-10 day long range forecast (top image below) from the Climate Prediction Center and the 8-14 day forecast (bottom image below) have the midwest and most of the eastern half of the country outlooked for above average temperatures. The bulls-eye for the highest probability of seeing above average temperatures for those periods is centered right over Illinois and Indiana.
Starting next Tuesday we could see a string of sultry summer-like days with highs into the 80s. Stay tuned.
