A cool front passed through the area last night and strong high pressure to our north will take control of the weather today and help to keep temperatures confined to much cooler levels near 70 degrees for afternoon highs. It’ll turn warmer on Saturday as the front turns around and moves north as a warm front and there can be some shower and thunderstorm activity as a result. High pressure will then build back into the region and Sunday and much of next week looks rain-free with high pressure in control. Meanwhile, the tropical scene remains quite active today with multiple systems to monitor. One system over the Bahamas this morning is likely to strengthen as it heads slowly towards Florida over the next couple of days and a batch of showers and thunderstorms over the eastern Gulf of Mexico may organize as it moves westward. In addition, two tropical waves now exist in the eastern Atlantic Ocean and the front running system will likely push into the eastern Caribbean Sea in several days and will have to be closely watched.
One final note, this happens to be Friday the 13th and only about 1% of full moons fall on a Friday the 13th. This one is even rarer as it is occurring near apogee, the farthest point in the moon's orbit. This hasn't happened since 1832 and won't happen again for more than 500 years.
