The extended forecast suggests fewer showers as we wrap up a soggy weather pattern. Air conditioning units have received a temporary break after constantly “humming along” during the super-hot July weather. As mentioned in previous columns, Sunday marked the 108th anniversary of the invention of modern air conditioning. In the 1900s, a Brooklyn printing plant was the first building in the world to be air-conditioned by Dr. Willis Haviland Carrier. Older Baton Rouge homes may have a large attic fan that prior to air conditioning provided relief as air was moved from room to room. Carrier’s cooling plant divided the air into two streams, one heated and the other cooled. In each room, these two air streams are proportionately mixed to produce a desired temperature.

Fastcast: Fewer showers.

Scattered showers. Partly sunny, high near 93. Calm winds becoming southerly 5 mph to 10 mph. Rain chance: 40 percent. Tonight: Partly cloudy, low around 76. Southerly winds 5 mph.
