Today’s discussion is very similar to yesterday’s discussion because not much has changed since then. A large area of high pressure is stationary over the Western Atlantic offshore of the New England and mid-Atlantic coast. If this system was about 250 miles farther west, we would be experiencing beautiful summer weather with mostly sunny skies. But it is not, so we won’t. Instead, we will see periods of sunshine eclipsed by mostly cloudy skies. A strong flow of southerly and southeasterly winds will continue to pump up the heat and humidity.
As a cold front slowly drifts eastward from the Midwest, temperatures and humidity levels will climb, as will the chances for widespread showers and thunderstorms. We still think there will be a bit of improvement in the weekend weather, but it will continue very warm and humid Saturday with a 30% chance of isolated thunderstorms and downpours. And on Sunday, an isolated shower or thunderstorm will still be possible.
