Meteorological summer went out in sweltering fashion as highs surged into the mid- to even upper 90s. As September begins, the mercury trends downwards, but tropical moisture increases. Saturday’s still hot with just small rain chances. But odds of rain increase Sunday and Monday as temperature drop back into the 80s. Yes, Isaac’s moisture has a lot to do with this.
Through Tonight: A nice, albeit warm-ish evening. Skies are mostly clear as temperatures gradually slip back into the 80s and then 70s by midnight. Overnight lows range from the mid-60s in the cooler suburbs to the mid-70s downtown. A soft wind blows from the west at 5-10 mph.
Saturday: You’ll notice a slight uptick in humidity levels and clouds. This makes it slightly less hot than today, but it feels comparable with more moisture in the air. There’s a 30% chance of showers and thundershowers during the afternoon as a front lies in our vicinity. Highs are in the upper 80s to low 90s. A slight chance of showers and storms Saturday night with lows in the upper 60s to low 70s.
Sunday and Labor Day: Mostly cloudy with a decent (60 percent) chance of showers and thunderstorms as a plume of moisture ahead of the remnants of Isaac interacts with a front over the region, especially during the afternoon and evening hours. While it won’t rain the whole time, some of the rain that falls could be locally heavy. Highs are in the low-to-mid 80s with lows near 70.
