A Hot and Dry Beginning Followed by a Drought Buster in Southern Arkansas
 

A ridge of high pressure over the western United States wobbled toward the middle of the country to begin September. Under the high, temperatures were above normal.

On the 1st, the mercury topped out at 103 degrees in Russellville (Pope County). Monticello (Drew County) was not far behind with 102 degrees. De Queen (Sevier County), Fort Smith (Sebastian County), Pine Bluff (Jefferson County) and Texarkana (Miller County) all had maximums of 101 degrees. From the 7th through the 10th, afternoon readings were in the mid 90s to around 100 degrees, and several records were tied or broken.

Spotty rainfall was noted during the first half of the month. Less than a quarter of an inch was common at most locations. Where it did rain, there was some severe weather.

On the 1st, an incoming cold front triggered scattered severe storms from Little Rock (Pulaski County) westward.

 

Cool outflow from collapsing storms in northwest Arkansas triggered new storms near Paris (Logan County) between 500 pm and 530 pm CDT on 09/01/2013.
Trees and power lines were downed at Paris (Logan County) and also just southwest of Conway (Faulkner County). Highway 71 was blocked by fallen trees four miles south of Mena (Polk County). Damaging winds knocked out power northeast of Pottsville (Pope County), to the west of Macon (Pulaski County) and at Plainview (Yell County). Golfball size hail was reported close to Mountainburg (Crawford County).

On the 12th, storms bubbled up again ahead of a more significant front. Quarter size hail was reported at Alexander (Pulaski County). Near town, a truck was apparently struck by lightning along Interstate 30. The same storm downed trees at Bryant (Saline County) as it collapsed.

 

Much cooler air followed the front, with high temperatures in the 70s/80s by the 14th. Readings dipped into the upper 40s at a few spots by dawn on the 15th. Clockwise flow around high pressure ("H") in Texas drove a cold front toward the Gulf Coast on 09/14/2013.

A moderate (D1) to extreme (D3) drought was noted across southern Arkansas on 09/17/2013.
Given hit and miss rain, a drought worsened across the southern counties.

As vegetation dried out, a wel ltimed deluge was on the horizon. Rain was heavy at times on the 19th/20th, especially in areas that needed the most (the south). Two to four inch amounts were common in southern Arkansas, with locally over six inches.

 

Thirty six hour rainfall ending at 700 am CDT on 09/21/2013.

In the thirty six hour period ending at 700 am CDT on the 21st, Texarkana (Miller County) racked up 6.68 inches of rain! Pine Bluff (Jefferson County) had 4.26 inches, with 3.31 inches at De Queen (Sevier County), 2.73 inches at West Memphis (Crittenden County) and 2.59 inches at Monticello (Drew County).

 

Forty Eight Hour Rainfall (through 700 am CDT on 09/21/2013)
Site Amount (Inches)
Texarkana (Miller Co) 6.68
Bluff City (Nevada Co) 6.05
Hope (Hempstead Co) 6.00
Prescott (Nevada Co) 5.67
Ashdown (Little River Co) 5.60
Stuttgart (Arkansas Co) 5.32
Sparkman (Dallas Co) 5.26
Marvell (Phillips Co) 5.10
Delight (Pike Co) 4.59
Arkadelphia (Clark Co) 4.52
Rohwer (Desha Co) 4.42
Fordyce (Dallas Co) 4.27
Leola (Grant Co) 4.27
Pine Bluff (Jefferson Co) 4.26
Sheridan (Grant Co) 4.13
Kelso (Desha Co) 3.83

 

Some of these amounts exceeded what would normally be expected during the entire month of September. Given this much rain, there would typically be areas of flash flooding. However, with a drought taking place, much of the water went into the soil, and high water problems were spotty at most.

While flooding was not an issue, downed trees were a problem. Trees weakened by drought were susceptible to a lot of rain (easier to uproot in a wet ground) and wind (occasional gusts over 20 mph in places). At Bismarck (Hot Spring County), for example, Arkansas Highway 84 was blocked by fallen trees twice during the morning of the 20th.

 

 

On the 28th, the southwest picked up more rain, with over three inches in places. Texarkana (Miller County), for example, got 3.02 inches.

The month finished with close to ten inches at Texarkana (Miller County), which was nearly three times the normal amount. At or above normal precipitation was also noted at El Dorado (Union County), Little Rock (Pulaski County), Pine Bluff (Jefferson County) and West Memphis (Crittenden County). Meanwhile, it was very dry in northern Arkansas. Several locales in the north had rain deficits of more than an inch and a half, including Fort Smith (Sebastian County), Harrison (Boone County) and Jonesboro (Craighead County).

In the Tropics
 

There were four named storms in September. Tropical Storm Gabrielle formed near Puerto Rico late on the 4th. The system moved slowly to the north, and eventually dissipated on the 5th. Gabrielle regained tropical storm status on the 10th near Bermuda, and tracked to the northeast and well away from the east coast of the United States. The storm weakened on the 13th.

Tropical Storm Humberto came to life on the 9th well out in the Atlantic Ocean toward the Cape Verde Islands. The system became the first hurricane of the season early on the 11th, and remained as such for a couple of days. Humberto weakened quickly on the 13th, and was pretty much gone before resurfacing as a tropical storm on the 16th. The storm finally fell apart on the 19th over open water.

Ingrid formed on the 12th in the southern Gulf of Mexico, and became a minimal hurricane on the 14th. The system made landfall near La Pesca, MX on the 16th.

As the month closed, Tropical Storm Jerry developed in the central Atlantic Ocean on the 30th. Jerry did not last long, and lost tropical characteristics by October 3rd.
