The WSR-88D (Doppler Weather Radar) showed small areas of rotation in central Arkansas at 317 pm CDT on 09/13/2008. Six tornadoes were counted in Garland, Hot Spring, Lonoke, Perry and Saline Counties. These tornadoes caused mostly tree damage, with some structural damage just to the southwest of Cabot (Lonoke County).

These tornadoes were all rated EF1 on the Enhanced Fujita Scale. Six tornadoes (all rated EF1) were spawned in central Arkansas on 09/13/2008.

Pressure changes around Ike were large. The pressure fell rapidly as Ike approached, but went up quickly as the system departed and a cold front pushed through the region. 

 

These falls/rises created very windy conditions. Winds increased in southwest Arkansas during the afternoon of the 13th, and across the rest of the state during the overnight hours and into the morning of the 14th. Wind speeds of 30 to 40 mph and gusts over 50 mph occurred. Numerous trees and power lines were downed. Six hour pressure changes as of 7 am CDT on 09/14/2008.
In the picture: Six hour pressure changes as of 7 am CDT on 09/14/2008. Initially, there were pressure falls (more than 10 millibars/6 hours) in Arkansas (ahead of Ike) and ascending air to support showers and thunderstorms. Strong pressure rises (over 10 millibars/6 hours) followed, with a sinking motion and much cooler/more stable air. Between falls and rises, there was an extreme isallobaric (pressure tendency) gradient...leading to a lot of wind across the region.

8 am CDT (09/14) WSW18G29 1004.7 +3.3
9 am CDT (09/14) SW16 1006.4 +1.7
In the table: As the pressure fell with the approach of Ike, winds were generally from the south to southeast. As the pressure leveled off and began rising rapidly (as Ike moved away), winds shifted to the west or southwest. The highest gust occurred as pressure falls transitioned into pressure rises, with a 61 mph gust at 534 am CDT on 09/14/2008.

 

Twenty four hour rainfall as of 7 am CDT on 09/14/2008. Rainfall fell short of the deluge that occurred with the remnants of Gustav (September 1st through the 4th). This was mostly due to the fast movement of Ike. One to three inches (and locallly more) was common in the west, with less than an inch in the east.
