Remaining Hot & Humid – Scattered Showers Increase by Mid-Week – Saturday Evening Forecast Update 9 PM

Scattered showers and storms developed earlier this afternoon during peak heating, but as expected, some areas did stay dry. Temperatures quickly made it into the low 90s this afternoon and with all the moisture in the atmosphere, the heat index exceeded 100 degrees in most locations. A few more stray showers could pop up overnight tonight as well, but most areas should stay dry.

The forecast for Sunday is actually trending drier based on the latest model guidance. Both the NAM and GFS models bring in some drier air aloft and that should help suppress rain chances. But, with the lingering moisture and daytime heating, isolated showers or storms could develop tomorrow afternoon. Where they do form, torrential downpours and dangerous lightning are possible. Otherwise, expect another hot and humid day with highs in the low 90s and heat indicies exceeding 100.

Moisture continues to remain and a frontal boundary begins to slowly approach us from the north by midweek, and a general increase in scattered storms is expected by this time period. However, it looks like this frontal boundary will stall around our area, which means relatively higher rain chances compared to typical summertime climatology for the end of the week into the weekend. Temperatures will be a little warmer than what we’ve been seeing over the last few weeks with these rainy setups, as highs each day will range from 90 to 92.

Elsewhere in the tropics, Dorian regained tropical status briefly, but the NHC discontinued advisories earlier this afternoon. No other tropical development is likely in the Atlantic Basin over the next 48 hours.
