Extreme heat today & heat breakdown

No way around it... It is going to be HOT today. The humidity will still be rather low so we will be dealing more with a dry, desert-like heat.  The low humidity will also allow for the huge temperature jump.  The heat does not have to heat up much moisture in the air... Think of it this way... Get two cooking pots.  Fill one full of water, fill the other only a quarter of the way with water.  Heat them both up on the stove with the same heat and see which gets hotter after five minutes.  It takes a lot longer to heat up the added water so the one with the lesser water will be much hotter.  So we will see our temps soar today to a high of 101... maybe even hotter in some of the traditional hot spots.  I was a little leery going that warm, but what Missouri saw yesterday will be similar to us today... but we will be slightly hotter since the winds will be stronger coming out of the southwest with warm air advection.  This will be the hottest high temperature I have ever forecasted for and the first time since August 17, 1988 that we have broke the 100 degree mark in Dayton.  At the bottom of the blog I included some 100 degree stats that the National Weather Service from the Wilmington, OH office put together... some interesting stuff.  Like... the record high temp for June EVER for Dayton is 102.  Enjoy.

The heat will start to subside a little... mid-upper 90's for the weekend.  The humidity slowly climbing will make it feel like the low 100's still.  With the humidity climbing and temps staying so warm we could fire off an isolated shower and storm any day after today.  It will be the spotty afternoon showers and storms so not everyone will see the rain, but some seeing rain is better than none of us.  Highs will stay in the low 90's for early next week and by the Fourth of July, next Wednesday, we will still be dealing with 90's and a chance for afternoon showers and storms.  Stay cool, enjoy the facts below, and have a good one!
