The center of Tropical Storm Isaac moved through central Louisiana Thursday. The Isaac remnant was located just west of Baton Rouge at 1:00 AM and tracked to near Jonesboro by 2:00 PM. Such a close encounter with a tropical cyclone normally brings extreme rainfall and high wind. Just about eveyone in central Louisiana felt the wind but few people received the heavy rain.
Wednesday through Thursday morning brought the highest wind to central Louisiana. Sustained wind was mostly between 20 and 40 mph with peak gusts of 50-60 mph. Power outages, damage to awnings, and felled trees resulted from the wind.
All of the weather watchers I spoke with received rain. As tropical systems go, however, the totals were light. The heaviest rain occurred in the eastern sections of the KALB viewing area. Natchez, Mississippi measured 4.66 inches, Ferriday saw 3.61 inches, and Jonesville recorded 2.50 inches. Not bad for a tropical cyclone!
With the departure of Isaac, the moisture he brought will become entrenced across central Louisiana. A strong ridge of high pressure will build next week and will send the thermometer upward. Temperatures in the 70s at night and the 90s during the day will combine with high humidity to bring the heat index soaring above 105 degrees. Yes, it will be September by then but the weather sometimes pays no attention to the calendar.
