Heat Advisory, low rain chance…July 17th, 2012 at 6:58 am by Jamie Jarosik under Weather
It’s going to be another extremely hot and humid day in the Miami Valley, with temperatures in the mid-90s… and our heat index (or feels like temperature) at or just above 100-degrees. The entire area is under a HEAT ADVISORY from noon until 8pm today. With dew points in the lower 70s, the humidity will be way up there:
When it’s that muggy outside, it is hard for our bodies too cool off effectively. Our natural cooling system (sweating) is being offset by the high moisture content. Sweat evaporates efficiently when the air is dry… and evaporation is a cooling process. But high humidity slows this down significantly… so your sweat isn’t evaporating… and that in turn makes you sweat even more. Sooo this can show you how HYDRATION is so very important in a weather set-up like today. Drink water, water, water… and make sure the kids are drinking, too, even if they’re not thirsty.
I’ve sort of been laying low on the half-marathon training lately, because I was sick for awhile… and then it turned into a sinus infection, and I didn’t feel like training at ALL. I am starting to get back into the swing of things, and have been for a few short runs over the past week or so. Yesterday, I went with both kids in the jogger around 11am… and my goodness… it was already oppressive at that point. Today will be very similar, so I’m sitting this one out. During the afternoon yesterday, I received about nine raindrops at my house from this cloud:
A few isolated showers popped up during peak heating. This may happen again today… but like yesterday, most spots will not see rain. A better rain chance comes with a cold front dropping in on Wednesday:
Scattered showers and thunderstorms are most likely in the afternoon hours. The front is a slow-mover, too. So while Wednesday still looks hot and humid, the rain chance will at least linger into Thursday… and possibly even into Friday. By Friday and Saturday, humidity will come down to more comfortable levels, and highs will be closer to normal… in the mid-80s. Hang in there!
