DECATUR, Ill. (WAND) - It's warming up fast after a sluggish start to May. Not only will air temperatures peak in excess of 80 degrees this weekend, making it the warmest so far this year, but there's also higher humidity.  

The combination of lowering pressure with the passage of our latest warm front with higher humidity will be enough to trigger a couple of thunderstorms Saturday morning. Afterward, a weak cap will develop on the atmosphere, lending toward dry afternoon weather. If the cap erodes, an isolated thunderstorm can redevelop Saturday evening, but after Saturday morning, a large part of the remainder of the weekend will be free of rain.  

If area lakes are calling you, water temperatures are running in the mid-60s.  Just make sure to have the free WAND weather app handy with futurecast radar and watches/warnings that track your location. 

It's time to sit back, relax and enjoy a summer-like weather appetizer.  Stay sweaty and stay weather-aware out there.
