Indiana’s Weather For Friday

August 24, 2012

Our weekend weather anchor doesn’t wear pancake makeup.

It’s high pressure, anchored near Virginia until Sunday. The clockwise circulation around this system will bring a continued flow of air from the south. The prospect for fair weather cumulus clouds is a little higher today and tomorrow, but the sun will still be strong.

We’ve been warming ever-so-slowly the last few days.

I think humidity will still be a non-factor today, and it will increase a little this weekend.

The last two weekends have been too kind. Three out of four of those days featured highs just into the upper 70s. We’ll be closer to 90 this time around. A frontal system should approach late Sunday afternoon into Sunday evening. The best chance of showers and storms is still on Monday.

The attached chart shows potential precipitation, and the prospect of an inch of rain in the northwestern third of Indiana. Note also the bulls-eye over Florida, where 8 inches of Isaac-related rain could fall.

Isaac will pound the Dominican Republic and Haiti today and approach southeastern Cuba tonight. As it moves into the Gulf next week the heaviest rainfall is expected to occur in a 50 – 80 wide wide swath along and to the right of where the center tracks.

If the remnants of the system hold together and curve toward the Ohio River Valley we could see some beneficial rain, but that’s not going to happen until at least next Friday.

Remember Hurricane Ike? The remnants from that storm tracked across our state September 14, 2008. Winds gusted up to 70mph, including 63 mph at the Indy Airport. Numerous power lines, tree limbs and branches were brought down, and thousands lost power.

Leftovers from Hurricane Erin caused a four delay in the start of the second running of the Brickyard 400 in 1995. Usually there’s less NASCAR weather drama compared to the “500” at the Speedway, simply because of the time of year the events are scheduled.
