Indiana’s Labor Day Weekend still looks wet, with 4-7 inches of possible rainfall.
Welcome to “As The Tropics Turn.”
Isaac turns toward the north/northwest later today, and then to the north Friday. The center of the storm will still lumber through Louisiana today, but finally move into Arkansas tomorrow, and southern Missouri by Friday Night.
The forecast track eventually turns again, from southwest Illinois toward the heart of central Indiana Sunday into early Monday. Our heaviest rains should fall from Saturday afternoon through Sunday. The chance for precip should drop on Labor Day itself.
Flooding still appears to be the biggest threat, but in the past tropical leftovers have brought damaging wind and weak tornadoes into Indiana. Issac has the potential, at least on paper, of deleting our deficit with respect to rain.
The Indianapolis year-to-date rain total is 22.49 inches, which is 6.64 inches behind the average. It is certainly possible we will see that much this weekend.
This Labor Day Weekend shouldn’t top the all-time 24-hour rainfall record set on Labor Day 2003, which was 7.20 inches. THAT all came in one day and caused widespread flooding in central Indiana. Not only will this rainfall probably be more spread out, it will fall on relatively drier ground. For example, parts of southern Indiana still have only received less than an inch of rainfall in the last few week, after an exceptionally dry June and July.
There’s been 6.51 inches of rain officially this month in Indy, so far. If we get past 8 inches of rain for August this weekend it will be the wettest month since 9.73 inches was measured in June of 2010!
Today’s temp take a “turn” for the hotter, but the sun is still the star until the slight storm chances begin tomorrow afternoon, and kick into high gear this weekend.
The average high today is 83 and the average low is 63. The records are 95 and 42. Sunrise time is 7:12 and sunset comes at 8:19. That’s two minutes less daylight than yesterday.
PAUL’S PREVIOUS PREDICTION:
