How Dry Is It?
Abnormally Dry Conditions
At times, below normal precipitation will lead to a lack of ground water and worsening drought conditions in Arkansas. Check out the latest conditions below.

Percent of normal rainfall in April, 2013. Rainfall was appreciable across the southeast half of Arkansas in April, and also in the far northwest. That was not the case elsewhere. in the southwest, some spots received less than half of the normal rain.

Locales that got surplus precipitation included El Dorado (Union County), Fayetteville (Washington County), Pine Bluff (Jefferson County) and West Memphis (Crittenden County). Totals were more than an inch below normal at Texarkana (Miller County).

The Cost of the Drought

According to a study by the University of Arkansas Division of Agriculture, ranchers in Arkansas lost at least $128 million due to drought conditions from August, 2011 through July, 2012. The losses were mostly the result of a short supply of hay and rising hay costs. It became too expensive to feed cattle, and ranchers were forced to sell their cows.

At one time, 85% of pastures were in poor or very poor condition. This led to lackluster hay production and the smallest hay yields since the mid 1950s. While shipping hay from surrounding areas was an option, red fire ants complicated the process. Many hay growers in the southeast United States live in fire ant quarantined counties. Despite good intentions, hay could not be transported from a quarantined region to a non-quarantined region unless the hay was certified as fire ant free and stored properly (above ground).

While the cattle industry suffered, most crops survived the drought. Early planting due to a mild winter and ample supplemental water through irrigation led to good plant development and decent yields.

 

Precipitation deficits in 2012.
In the picture: Precipitation deficits in 2012. The year began with a spike (upward) of rain in March followed by the driest April through July period in Arkansas history. Areas of heavy rain returned to southern and eastern sections of the state in August and September. There was a downward trend across much of the region in October and November, with closer to normal totals in December.
 

In early May, a moderate (D1) drought affected most areas south and west of De Queen (Sevier County), Mufreesboro (Pike County) and Magnolia (Columbia County).

 

No More Severe/Extreme (D2/D3) Drought

During a record dry period (April through July) in 2012, extreme drought (D3) conditions developed by June 19th. Roughly 81% of the state was in at least D3 status at the end of July. The D3 area slowly shrunk in the fall/winter, and was confined to counties in the northwest. It finally disappeared on February 5th, 2013. While D3 went away, D2 remained in the west for a couple of more months (early April) and then vanished. 

 

Farther north/east, while there were some D0 conditions, there was no drought at all in eighty percent of the state.

A moderate drought was noted in southwest Arkansas on 05/02/2013.

Soil moisture on 05/01/2013.

The ground water supply was pretty close to normal statewide. The highest moisture levels were in the southeast, with the lowest in the southwest.

In the picture: Soil moisture on 05/01/2013. Values greater than or equal to 30 percent are considered at/above normal, with below normal values under 30 percent.

 

Streamflow was also about normal, but below normal in the southwest.

Overall, area lakes were in decent shape. Levels were generally at or a little above pool capacities.

On May 2nd, there was a low wildfire danger, and no burn bans were declared in any of the 75 Arkansas counties.

 

 

The drought outlook through July, 2013.

As far as the future weather pattern, neutral conditions (close to normal water temperatures in the equatorial Pacific Ocean) are expected to hold through the summer. Given a neutral scenario, research through the Climate Prediction Center indicates a bias toward at/above normal precipitation early in the period (May/mid-June, 2013), especially across the north.

 

Precipitation forecast for May through July, 2013 (courtesy of the Climate Prediction Center).
In the picture: Precipitation forecast for May through July, 2013 (courtesy of the Climate Prediction Center). Below normal (B) rain is favored from parts of the high Plains to the Rockies and the Pacific Northwest. Elsewhere, there are equal chances (EC) for above normal, near normal or below normal rain.
 

During this time frame, there is an outside chance of a significant precipitation event (several inches of rain over a wide area) if the right ingredients come together (i.e. a slowly moving or stalled front and ample moisture). As long as cool air masses continue to penetrate this far south (to bring below normal temperatures), this is a possibility.

There should be a trend toward drier conditions as the period winds down (late June/July, 2013). This would not be unusual as summer usually features scattered/hit and miss thunderstorms.   

Overall, the pattern looks promising, with enough moisture to stave off drought in much of the state. The area to monitor the most closely is the southwest. This is where conditions have been the most dry to begin the year.
