Muggy with thunderstorms rolling through later this afternoon and highs in the upper-70s. The story this weekend is about building heat and humidity. A Bermuda high becomes the dominant feature bringing an extended period of 90ºF+ heat into next week. While this high is anchored in the western Atlantic, we won’t see any appreciable chances for rain at least until later in the week next week.

Rest of today – mostly cloudy with high temperatures in the upper-70s. HRRR simulated radar runs this morning consistently signalling the arrival of a line of thunderstorms around 3-4PM this afternoon. Behind these storms, temperatures overnight expected to be in the mid-60s.

Saturday – sunny with high temperatures much warmer in the upper-80s. Overnight lows in the low-70s. Humidity will be building as well due to the influence of southwesterly/westerly flow bringing in a warmer and moisture-laden air mass.

Sunday – high temperatures around 90ºF with mostly sunny skies. Overnight lows in the low-70s.

Monday – with a Bermuda high still in place, expect high temperatures to once again reach around 90ºF with higher heat index values due to the humidity. Overnight lows in the low-70s.
