WEEKEND WEATHER FORECAST

You don’t need me to tell you today was a spectacular Fourth of July, weather-wise. Low humidity, comfortable near-average temperatures, and sunny skies!

We’ll have this great weather through the balance of this weekend. The noticeable difference by Sunday will be higher temperatures and somewhat higher humidity.

Beyond this Weekend

Of interest is a developing low pressure system with tropical characteristics (a warm center low) developing near Jacksonville FL. This will move up the coast Monday into Tuesday with rain, possibly heavy. The AI models are similar, but the track inland or somewhat more eastward is still to be determined.
