TROPICAL DEPRESSION BILL DISCUSSION NUMBER 21
WIKI-HURRICANES FORECAST CENTER
1000AM CDT SAT JUN 20 2015
Bill continues to produced organized convection over the Ohio River Valley. Radar imagery depicted continued spiral banding and central shower activity with the storm near Frankfort, Kentucky, near the Appalachian Mountains. This kind of inland tropical cyclone persistence has largely been unprecedented, but regardless, Bill is still expected to slowly weaken and become disrupted over Appalachia before merging with an extratropical cyclone in 24 hours.
