We all remember the heat and humidity that we dealt with last Friday, which pushed our heat index numbers up to near 120º in some areas! I want everybody to keep that in mind as I talk about our next round of heat and humidity.
Another large ridge of high pressure will continue to spread in for Friday allowing more heat from the Plains to shift eastward. There will be two main differences between what we see this Friday and what we saw one week ago. For starters, temperatures shouldn't be quite as hot. Last Friday brought highs between 100 and 105 degrees. This Friday will bring temperatures closer to 100 degrees. Last week we also had oppressive levels of humidity, with dew points in the mid to upper 70s. This Friday, our dew points will still be high, but not as high. Dew points in most areas will only climb to near 70 degrees. Even with these less extreme numbers we are expecting for Friday, the combination of heat and humidity will still take a toll. Heat index numbers will be around 105 degrees during the afternoon, with some isolated areas approaching 110. As a result, a heat advisory has been issued for all of central Virginia for Friday afternoon. A weak cold front will approach over the weekend, giving us a few rain chances and this will help to knock our highs back down into the lower and mid 90s.
If you're looking for a cooling trend, you might be out of luck! The next seven days all feature afternoon temperatures at or above the 90 degree mark!
