Rain Chances Continue Through the Weekend
POTENTIAL TROPICAL STORM ISAIAS MAY AFFECT SOUTHEAST BY LATE THIS WEEKEND
The story with the weather will remain the same locally for the next couple of days. Weak disturbances aloft will move from west to east through our area, and coupled with moisture being funneled out of the Gulf of Mexico, showers and thunderstorms will be the result. While it won’t be an all-day washout every day, all locations stand to see at least some rainfall between now and the weekend. As a result of the increased cloud cover, high temperatures will be held in check, mainly in the 80s to around 90 degrees, while overnight lows will be in the lower to mid 70s.
With the disturbances around, the rainfall won’t follow the usual summer pattern of developing in the afternoon and dying off as daytime heating goes away in the evening. Don’t be surprised to hear a rumble of thunder or two overnight or in the morning hours as well through the end of the week. The good news though is that with very light winds aloft, severe weather will not be an issue. Any thunderstorm, however, is capable of cloud-to-ground lightning that can be dangerous to anyone outdoors, so head inside if threatening weather approaches!
By the end of the weekend, all eyes will begin to turn towards what will likely then be Tropical Storm Isaias. The storm is currently labeled a “potential tropical cyclone” since it lacks a closed circulation that would qualify it as a truly tropical system. There are still MANY more questions than answers regarding the eventual path and intensity of the storm; variables such as interaction with land areas such as Hispaniola and Cuba and the strength of the high pressure to its north all will make a big difference in the outcome of Isaias. For now, we do not expect major impacts from the storm locally, but that may change should the forecast shift the storm further westward.
Outside of any potential tropical impacts, rain chances should decrease somewhat by early next week. Temperatures will respond by rising back to near average levels with highs in the lower 90s and lows in the lower 70s.
