Even though it felt like it might rain at any minute given all the moisture in the air, we’ve managed another day without more than a handful of spots getting doused. However, in the city and to the south and east, some heavy downpours and lightning have occurred and remain possible. Temperatures in the mid-80s to near 90 for highs aren’t too bad, at least until you factor in the humidity.
Through Tonight: Some showers or storms are possible into evening over mainly the southern and eastern parts of the area, but otherwise it’s partly cloudy. Even though a “cold front” is passing by/washing out in the area, any change in humidity should be minor for now. Lows are again near 70 in the suburbs to the mid-or-upper 70s downtown.
Tomorrow (Thursday): With the first front off to the south, another one that won’t accomplish too much should press in by late day. Overall, we should see a fair amount of sunshine, but there could be increased clouds in the afternoon along with an isolated to scattered shower or thunderstorm. Highs reach the upper 80s to low 90s. Humidity is down a bit, but probably not into a range we’ll cheer about.
River rise post-Isaac? Experts say the rain from Isaac will bring some relief to the lower Mississippi River, but not enough. While the river will continue to see temporary rises, it should drop again in the next few weeks without more rain as widespread drought conditions continue to take their toll.
