HEAT WAVE TO BAKE THE NATION

Heat normally peaks in late July and it looks like it is right on schedule. Last year interestingly, we did not reach peak heat until September 4th with a high of 94°.

Thursday could reach the 90°, the 10th of the season but with growing levelas of humidty the heat index will close in on 100°.

It will get worse before it gets better and as expected heat advisories have been expanded into Indiana, going into effect starting 10 am Friday and issued through Saturday evening.  I fully expect that they will be extended into Sunday afternoon as well.

SIGHTS ON RELIEF

Looking like the heat will have stamina lasting well into next week.  There is a front dipping south later Monday and Tuesday that offers a chance of storms and a slight easing of humidity Tuesday and Wednesday.

Real heat relief showing up longer ranger and could arrive late next week.  Comparing the forecast upper air maps for this upcoming Saturday up against late next week’s Friday forecast , a definitive change in the offing to the jet stream pattern. I’m posting the Euro model upper air forecast for Friday July 29th below.  That should be a more significant cool down and more importantly an easing of humidity.  Stay cool until then!
