We all know that it's going to be hot in Virginia in the summer. We also know that the levels of humidity that accompany the heat can make things tolerable or absolutely miserable. Last week brought a dose of that misery in the form of record heat, along with extremely muggy conditions. Now change is on the way...
A cold front will drop through the area Monday night, bringing some scattered showers and thunderstorms. Behind this front the temperatures will remain hot, BUT we will see a considerable drop in the dew point (or the number that we use to measure the moisture in the air). Dew points have consistently been running in the mid 70s for the past few days, which is very steamy and tropical. Dew points behind the front will drop into the lower and middle 60s on Tuesday afternoon, which will feel much more comfortable, despite the fact that temperatures will stay in the lower 90s.
Enjoy this brief reprieve in the humidity because another surge of extreme heat and humidity will make their way back to our area by Friday. Highs once again will be in the upper 90s with the heat index numbers in excess of 105º.
