It’s Not The Heat….It’s The Humidity

Oh baby, it’s hot out there!  Or more correctly…Oh baby, it’s a steam bath out there!  Both statements are true, but unusually high rainfall has lead to high soil moisture content, which in turn leads to, well, a steam bath.  Mid afternoon temperatures are in the mid 90s, but the dewpoint temperatures are in the mid to upper 70s.  That’s something you don’t see everyday in Oklahoma:

Take some typical July heat and combine it with unusually high humidity, you get heat index values that are dangerously high:

When the heat index gets this high, it’s can be life-threatening.  If you have to be outside, plan on taking plenty of breaks, drink plenty of water (even more than you think you should), and don’t overexert yourself.  This type of heat will be with us the rest of the week.  As the soil moisture gradually evaporates, the humidity levels will drop off a bit.  In the meantime, the National Weather Service has issued a heat advisory for our area through Thursday:

The only shot at a thunderstorm will come Thursday night into Friday morning, mainly in northern Oklahoma.  Of course a thunderstorm may cool off the temps a bit, but it keeps the humidity up as well.
