THE BERMUDA HIGH WILL BRING US MORE OF THE SAME… WARM AND HUMID WITH JUST A CHANCE OF SHOWER OR THUNDERSTORM IN SPOTS… TROPICAL STORM ERNESTO MOVES WESTWARD ACROSS THE CARIBBEAN SEA

The weather pattern over the next few days will feature high pressure to our east (referred to as the Bermuda High) creating a light southerly flow which will continue to bring up warm and humid air. While there are no major systems or disturbances nearby to spark showers or thunderstorms, it is so humid that any little trigger can result in convection such as a sea breeze boundary. The National Weather Service only has the chance of rain at 20% which means that most of us will not see rain each day this weekend but a few of us could have a heavy downpour or thunderstorm. The highest chances in a pattern like this are normally in the afternoon and early evening hours. A cold front will be slowly moving towards the Mid-Atlantic States early next week but will be weakening as it comes closer to our region. Rain chances will go up a bit early next week. This time of year, it is very hard for cold fronts to make progress south and east as the Bermuda High is normally very strong and does not allow these fronts to move that far south. In addition, the cool, dry air behind the front has less of a push this time of year…. What about the tropics? Well, Tropical Storm Ernesto is moving westward across the Caribbean Sea and it may become a hurricane this weekend. Folks on the Yucatan Peninsula and along the Gulf of Mexico should pay close attention to this storm as it moves west.  I just learned that we have a new tropical storm in the Eastern North Atlantic Ocean and that would be Florence. There is also an area over the Bahamas that has to be watched for development but right now, the National Hurricane Center is saying that it is very disorganized and will take a while before anything develops. So, the tropics have come alive and since it is now early August, that is no surprise. This is the time when you should have your hurricane emergency plans in place should a storm threaten your area. I will have an update on Sunday.
