Severe Storms/Heavy Rain on September 24-30, 2012 |
 |
| |
|
|
A cooler than normal theme continued from mid into late September as a cold front entered the state from the north on the 22nd. |
| In the picture: The pattern at 700 am CDT on 09/24/2012. High pressure ("H") over the Ohio Valley provided cool/dry air in Arkansas behind a stalled front to the southwest. |
| By the morning of the 24th, low temperatures were in the 40s and 50s. |

The front eventually stalled to the southwest. Warmer air and more moisture tried to overrun the front (into Arkansas) early on the 24th. At the same time, a system aloft interacted with the front, and scattered thunderstorms flared up north and east of Little Rock (Pulaski County). Given cool air in place, ice (hail) formed easily in developing storms.

 |
Concord and Drasco (both in Cleburne County) had hail up to quarter size. There was a narrow swath of heavy rain, with amounts generally from a half inch to an inch and a half. |
| In the picture: The rainfall map showed where storms tracked during the early morning hours of 09/24/2012. Amounts (locally over two inches) were somewhat inflated due to ice (i.e. at the freezing level) and hail contamination (that the radar interpreted as liquid). Dual Pol (new radar technology) estimates were lower (mostly half inch to inch and a half amounts). |
| The front moved back to the north on the 25th, and hovered near the Arkansas and Missouri border. Afternoon temperatures climbed into the mid 80s to mid 90s (upper 70s and lower 80s are normal). |
 |
| In the picture: The pattern at 530 pm CDT on 09/26/2012. A front to the southwest moved to the north of Arkansas, and eventually became stationary across southern Missouri and northeast Oklahoma. Warmer air spread across the region, with scattered storms surrounding the front. |
|
On the 26th through the 28th, there were hit and miss thunderstorms over the northern and western counties. A few Severe Thunderstorm Warnings were issued by the National Weather Service. One storm dumped quarter size hail at Batesville (Independence County) during the afternoon of the 27th.

 |
| In the picture: Rainfall in the seventy two hour (three day) period ending at 1200 am CDT on 09/29/2012 was mainly over northern and western Arkansas, with precipitation shifting farther south the next two days. |

Three day rainfall totals were over two inches in spots across the north/west. Amounts from a tenth to a half inch were common in the northwest half of the state, with little to no rain in the southeast half.
Heavier amounts included 2.22 inches at Morrilton (Conway County) on the 27th, with 2.11 inches at Clarksville (Johnson County) and 1.96 inches at Batesville Lock and Dam (Independence County). On the 28th, a downpour resulted in 1.16 inches at Hardy (Sharp County).

The front gained momentum toward the south on the 28th. A storm system formed along the front in Texas, with several inches of rain promised for parts of the Gulf Coast. |
| In the picture: The pattern at 938 am CDT on 09/29/2012 featured a storm system ("L") over central Texas, and widespread rain north and east of the system. |
|
Some of this rain built into central/southern Arkansas. On the 29th/30th, Monticello (Drew County) tallied 2.62 inches. During the same time frame, El Dorado (Union County) got 2.24 inches.
|
| There were isolated reports of hail in northeast Arkansas on September 24th and also on the 27th. For a look at some reports, click here.
