Isaac in Arkansas (September 1, 2012)
 
The remnants of Hurricane Isaac ("L") were in eastern Missouri at 400 pm CDT on 09/01/2012. As September began (the 1st), the remnants of Isaac moved into eastern Missouri. The system produced heavy to excessive rain in parts of central and eastern Arkansas the previous two days. Tropical moisture was still in place, and temperatures climbed into the upper 80s to upper 90s. De Queen (Sevier County) made it to 100 degrees.
In the picture: The remnants of Hurricane Isaac ("L") were in eastern Missouri at 400 pm CDT on 09/01/2012. South of the system, it was very warm and humid (dewpoints in the 70s in central/eastern Arkansas), with breezy west to southwest winds. Models showed thunderstorms developing from northeast into central sections of the state. Winds are shown with white arrows. Dewpoints are dashed blue lines.

 

 

It appeared Isaac would have once last hurrah before heading toward the Ohio Valley. Models indicated there would be one more round of thunderstorms before the departure of the system. There was plenty of fuel (heat/humidity) to make this happen. The models were right. The satellite showed clouds building from northeast through central Arkansas at 415 pm CDT on 09/01/2012.

Mammatus clouds were in the sky above the North Little Rock Airport (Pulaski County) toward sunset on 09/01/2012.

Storms fired up quickly from northeast into central Arkansas, and became severe. There were quite a few microbursts and straight-line wind damage.

Trees and/or power lines were downed in and around Des Arc (Prairie County), Dixie (Woodruff County), Beebe and Judsonia (both in White County), Benton and Bryant (both in Saline County), Conway and Vilonia (both in Faulkner County) and near Morrilton (Conway County). A hotel in Hot Springs (Garland County) that was damaged by a microburst on August 5th was hit again.

In the far northeast closer to Isaac, a tornado (rated EF2) affected the Corning (Clay County) area. At a local airport, several hangars were damaged. Two hangars were struck particularly hard, and numerous aircraft inside the hangars were thrown. Damage may exceed $5 million. A few miles to the northeast, another weak tornado (rated EF0) touched down briefly in a field. These were the first tornadoes in the state since June 4th, and only the 12th and 13th tornadoes of the year.

 

Twenty four hour rainfall through 700 am CDT on 09/02/2012.
