Our typical heat pump pattern is in place today. The Bermuda high is setup to our southeast. We have a light southwesterly wind. Heat and humidity have definitely built up since yesterday.
Temperatures topped off in the low-mid 90s yesterday. Today we’ll aim more for solid mid 90s. There will be a couple of upper 90s inland. Dew points are in the 70s. This will put the heat index up to 99-104 degrees this afternoon. Keep in mind that these numbers are just below heat advisory criteria. So be prepared for that type of heat. Drink plenty of fluids, and take lots of breaks in the shade. We’ll have partly cloudy skies. There will be some isolated showers and storms during the afternoon into the evening.
Tomorrow we’ll have a little more humidity. We’ll also have a bit more clouds. Plus, there’s the chance for rain is a little higher. This should limit the temps a little, but only by a couple of degrees. High temps will still be in the low 90s. The heat index will be near 100. Scattered showers and storms will pop up during the late afternoon into the evening. There may be an even higher chance for rain during the evening and overnight. This will be ahead of a cool front. The front will arrive on Sunday. We’ll have mostly cloudy skies with scattered showers and storms. The benefit will be cooler temps. Highs will be in the mid-upper 80s. We’ll see similar weather on Monday. We’ll have a chance for at least a few scattered showers (if not more) through most of next week. Highs will be in the 80s.
In the tropics there is one tropical disturbance and one tropical storm. The disturbance is a couple hundred miles east of the Lesser Antilles. It is moving steadily to the west. It may bring some heavy rain to that island chain, but it only has a low chance for any formation over the next couple of days.
Meanwhile, tropical storm Ernesto is out over the northeastern Atlantic. It is moving to the northeast over cooler waters now. So it should start to weaken soon. It will likely become a weak area of low pressure within the next 12 hours. It is no threat to land as a tropical system, but it may bring some rain to Ireland as a non-tropical low.
