DECATUR, Ill. (WAND) -  Hot, summer weather is coming!   And, to understand why it's getting so hot, let us examine the first law of thermodynamics.  The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed. Instead, energy can only be transferred or changed from one form to another. This law implies that the total energy remains constant, accounting for energy exchanges through heat and work.

DECATUR, Ill. (WAND) -  Stuffy, stifling, muggy, sultry, sticky, steamy, oppressive: call it what you like, but Summertime humidity is in!  To better understand the suffocating nature of high humidity, let us first discuss relative humidity; after all, it is relative to its surroundings.  Relative humidity is a measure of the amount of moisture (water vapor) in the air compared to the maximum amount of moisture the air can hold at a given temperature. It's expressed in percentages.

DECATUR, Ill. (WAND) - Tonight's full Strawberry Moon isn't just any full moon. You see, recent smoke from Canadian wildfires remains suspended aloft, producing a hazy appearance.  At the same time, a lunar orbit that hasn't happened since 2006 will also be on display.  What astronomers call a major lunar standstill will linger for most of this year.
