Isaac and Ohio - 2 Days Out
With Isaac's slow movement in to northern Louisiana this afternoon we're getting more changes in the latest computer models. Yesterday's runs were decidedly north, while today we're trending south. Much further south than yesterday.
New ensemble is showing a large hook, one that almost makes it look like future runs will have Isaac make a full circle. Instead of yesterday's concensus of headed toward Chicago, now we're looking at Cincinnati as a target:
With this much run to run variation, it's really hard to tell where this thing is going now. However, Isaac's current path of NNW makes me believe it'll turn sooner rather than later. That makes me feel more confident that the reminants will go south.
With that I'm beginning to think it may go so far south that our rainfall totals could go down. The latest QPF isn't indicating that however, with parts of Central Ohio looking more around the 3"-4" zone:
As always, placement is everything. And this track is just too tough to call this far out. I'm still thinking rain will sent in by mid-morning on Saturday and last straight through to Monday, and I'm sticking with a 2" rain total also. Tomorrow's model runs will be the real ones to watch, and we should have an idea whether we're looking at flooding rains or just a wet weekend. I'll post again tomorrow.
