August, 2014 Storm Report
 
Short Weather Summary
 
While August had a cool beginning, the hottest weather of the summer was experienced during the month. It was certainly active, with rounds of thunderstorms producing heavy to excessive rain at times. However, precipitation was hit and miss and limited to a handful of days. In the end, amounts were subpar in much of Arkansas, especially the north.

 

Record Temperatures
 
There were a few record low temperatures tied or broken in early August. Check out the record below.

 

Site Record Low (Date of Occurrence)
Mountain Home 62 (08/04)
Stuttgart 68T (08/01), 66 (08/04), 66 (08/05)
Note: "T" means record was tied.

 

A Cool Beginning/Hottest Days of Summer/Wet in Places But Dry Overall
 

It was a cool start to the month on the 1st. High temperatures in parts of central and southern Arkansas failed to get out of the 70s. At El Dorado (Union County), the mercury peaked at 69 degrees. It was the coolest August high on record, breaking the previous record of 70 degrees on the 7th of 1997. It was only 73 degrees at Texarkana (Miller County), which shattered a daily record for coolest high.

 

Six hour rainfall from 400 pm to 1000 pm CDT on 08/08/2014.

Temperatures remained below normal through the first week of August. On the 8th, a cold front pushed into the region from the north and stalled. Scattered thunderstorms were triggered by the front in northwest sections of the state, and drifted slowly to the south into the Ouachita Mountains. At Danville (Yell County), 2.09 inches of rain was measured between 445 pm and 545 pm CDT. Between 700 pm and 845 pm CDT, Caddo Gap (Montgomery County) got 2.82 inches. In just a half hour (800 pm to 830 pm CDT), 1.45 inches dumped at Hatfield (Polk County).

On the 9th, a storm system arrived from northeast Oklahoma and interacted with the stalled front. A line of thunderstorms developed ahead of the system, and produced some wind damage. Trees were downed at Clarksville (Johnson County), Paris (Logan County), Dover (Pope County) and just west of Dardanelle (Yell County). At St. Paul (Madison County), 2.57 inches of rain fell. Just northwest of St. Joe (Searcy County), 2.19 inches was tallied in an hour (ending at 430 pm CDT).

A new front finally swept into the region from the Plains on the 11th, with drier air to follow. Cooler than normal conditions stayed a few more days.

 

The satellite showed a complex of storms forming along a boundary just to the north of Little Rock (Pulaski County) during the afternoon of 08/17/2014.

New storms repeatedly developed on the west side of the complex, and moved east over the same areas. This led to excessive rain.
 

It certainly felt like summer in places by August 17th. Temperatures topped out at 98 degrees at Newport (Jackson County) and 97 degrees at Jonesboro (Craighead County). There was another stalled front toward the Missouri border, with the weather becoming active around the front. While rain was spotty, it was excessive in places. Just north of Little Rock (Pulaski County), a narrow band of thunderstorms formed, and kept developing over same areas.

On the north side of Maumelle to Morgan (both in Pulaski County), radar estimated over six inches of rain in places. At the latter location, roads were under water and high water rescues had to be performed. Some people evacuated their homes as water levels came up.

 

Flooding was extensive around an apartment complex on the north side of Maumelle (Pulaski County) during the afternoon of 08/17/2014.
At the former location, two apartment complexes were flooded, and so was part of a subdivision.

Rain was accompanied by damaging winds. There was a 67 mph gust at the Little Rock Air Force Base (Pulaski County). Trees were blown down near Sylvan Hills (Pulaski County). Trees were also toppled at Des Arc (Prairie County), with trees on a vehicle and also a carport. At DeWitt (Arkansas County), a carport was damaged by thunderstorm gusts.

 

Storms mostly fell apart after dark, but lingered  along the stalled front across the north. During the wee hours of the 18th, another area of storms blew up in the southwest. This was in response to an incoming system from Texas.

Two to four inches of rain was widespread in the southwest, with some street flooding reported in Camden (Ouachita County). Near the aforementioned front, similar amounts were tallied in the northeast. Twenty four hour amounts as of 700 am CDT on the 18th included 5.75 inches at Manilla (Mississippi County), 3.85 inches at Lockesburg  (Sevier County), 3.08 inches at Blytheville (Mississippi County), 2.42 inches at Prescott (Nevada County), 2.37 inches at Nashville (Howard County) and 2.05 inches at Dierks (Howard County).

 

Temperatures reached at least 100 degrees at eleven sites from central into northeast Arkansas on 08/23/2014.

On the 23rd, thermometers reached at least 100 degrees at a dozen reporting stations. This included 102 degrees at Salem (Fulton County), and 101 degrees at Mammoth Spring (Fulton County), Morrilton (Conway County) and Mountain Home (Baxter County).

Note: With the exception of Batesville Airport (Independence County), Clinton (Van Buren County) and Flippin (Marion County), the stations listed above have a 24-hour reporting period ending around 700 am CDT. Therefore, while the readings occurred on the 23rd, they were credited to the 24th.

 

It was about as hot on the 24th, with many of the same stations (eight out of twelve) hitting the century mark again. The highest temperature was 102 degrees at the Batesville Airport (Independence County). McCrory (Woodruff County) joined the 100 degree club for the first time in 2014 (credited to the 25th because data at this site is collected in a 24-hour period ending at 700 am) .

While a few storms brought limited relief on the 25th, it was 99 degrees at Fort Smith (Sebastian County) and 98 degrees at Fayetteville (Washington County). At these sites, it was the steamiest day of the summer.

A ridge of high pressure ("High") was replaced locally by an incoming storm system ("Low") in the days leading up to 08/29/2014.

After an almost two week hiatus without rain in most locales, the hottest days of the summer were replaced by more clouds and good chances of rain by the 29th. A ridge of high pressure weakened, and this allowed a storm system to wobble toward Arkansas from the Plains.

Showers and thunderstorms were most widespread across the northwest half of the state initially. Several rainfall reports exceeded two inches. Twenty four hour totals as of 700 am CDT on the 30th included 2.87 inches at Ozone (Johnson County), 2.53 inches at Long Pool (Pope County), 2.32 inches at Guy (Faulkner County), 2.20 inches at the Clarksville Water Plant (Johnson County) and 2.02 inches at Conway (Faulkner County).

 

The WSR-88D (Doppler Weather Radar) showed widespread showers and thunderstorms across the southeast half of Arkansas at 1048 am CDT on 08/30/2014.
It was mild on the 30th as the storm system trudged to the east. High temperatures at most locations were in the upper 70s to upper 80s. Moisture was shunted toward the Mississippi River, and rain was widespread across the southern and eastern counties. There were a few measurements over an inch in the far southeast corner of the state

During the afternoon, three to more than four inches of precipitation fell in just a few hours near the Monarch community just to the northwest of Lakeview (Marion County). Flash flooding was reported, with at least 20 county roads washed away or damaged by high water.

While it may seem like there was a lot of rain in August, there was not overall. Deluges were spotty, and umbrellas were needed for a handful of days (which is typical in summer).

Adding up all the numbers, precipitation for the month was generally in the minus category. Deficits were one to more than two inches at Fayetteville (Washington County), Fort Smith (Sebastian County), Harrison (Boone County) and West Memphis (Crittenden County). Deficits this high were mainly in northern Arkansas.

In the Tropics
 

There was only one new storm in August, with another storm already in progress. Tropical Storm Bertha was near the Lesser Antilles to begin the month (formed on July 31st), and tracked across the northeast Caribbean Sea. The poorly organized system passed by Puerto Rico on the 2nd and the Bahamas on the 3rd. After leaving the latter location, Bertha strengthened to a minimal hurricane on the 4th. Bertha eventually curved to the northeast into the open Atlantic Ocean and weakened. Cristobal was very much like Bertha. The system became a Tropical Storm near the Bahamas on the 24th, and a minimal hurricane on the 25th. Cristobal raced to the northeast and became extratropical (lacking tropical characteristics) in the north Atlantic Ocean on the 29th.
