On October 25th, there was a freeze in northern Arkansas. Temperatures in the northern two to three rows of counties dropped into the mid 20s to lower 30s. It seems like a distant memory as spring made a return.

 

A large storm system aloft ("L") developed in the Rockies, with a ridge of high pressure ("H") along the Gulf Coast at 100 am CDT on 10/29/2013. Winds aloft switched from northerly (out of Canada) to southwest, and that sent daytime temperatures into the upper 60s to upper 70s on the 29th/30th.

When temperatures fluctuate wildly, the weather often becomes active. That was the case heading into the final days of the month.

 

After thunderstorms (round #1) mostly missed Arkansas to the north on 10/28/2013 (tracking fram Kansas into Missouri), another more significant batch of storms (round #2) arrived on the 30th/31st surrounding a new front from the west.

A large storm system in the Rockies ejected into the Plains. That sent a cold front toward the area. Surrounding the front, moisture levels were well above normal for late October.

Moisture not only came from the Gulf of Mexico, it streamed in from the Pacific. The eastern Pacific was active, with Tropical Storm Raymond (downgraded from hurricane status) near Baja California early on the 29th.

 

A large swath of showers and thunderstorms grew in this very moist environment, and built into much of Arkansas during the nighttime hours of the 30th and the early morning hours of the 31st.

Simulated radar data showed showers and thunderstorms becoming widespread and heavy (yellow, orange and red colors), especially in areas south and east of Little Rock (Pulaski County) during the morning hours (100 am CDT to 1000 am CDT) of 10/31/2013.

By 700 am CDT on the 31st, twenty four hour rainfall was over two inches in parts of the south. Lewisville (Lafayette County) had 4.14 inches, with 3.19 inches at Bluff City (Nevada County), 3.04 inches at El Dorado (Union County) and 2.10 inches at Moro Bay State Park (Bradley County).

 

The satellite showed enhancement (yellow and red colors) mainly from central Texas into western Lousiana at 330 am CDT on 10/31/2013. Rain was far heavier from central Texas to western Louisiana. Thunderstorms in these areas produced locally more than 10 inches of rain. Serious flooding was reported around Austin, TX. Hundred of homes were evacuated, with numerous water rescues performed.

Forty eight hour rainfall through 100 am CDT on 11/01/2013.

Moisture tended to pool around these storms, with less moisture available for storms in Arkansas. That may explain why rain did not become excessive locally.  

After 700 am CDT on the 31st, heavy rain continued in southeast sections of the state during the morning. At Kelso (Desha County), 2.18 inches was measured, with 2.04 inches at Kelso (Desha County), 1.90 inches at Eudora (Chicot County) and 1.75 inches at Rohwer (Desha County).

As rain tapered off in the afternoon, some warming occurred and the atmosphere slowly destabilized. The aforementioned front pushed into the region from the west, and encountered these unstable conditions. Isolated to scattered thunderstorms popped up along the front in northeast Arkansas, and there was some severe weather.

 

Structural damage was reported at Caraway (Craighead County), with debris blocking roads. A weak tornado (rated EF1) was identified during a damage survey by the National Weather Service in Memphis, TN. It was the first tornado in the state since June 1st, and the 31st tornado of 2013. 

In the pictures: The WSR-88D (Doppler Weather Radar) picked up some rotation as a thunderstorm approached Caraway (Craighead County) at 734 pm CDT on 10/31/2013. At the same time, non-meteorological targets (possible damage debris) were detected (through dual polarization technology) around the area of rotation. A Tornado Warning was issued by the National Weather Service in Memphis, TN.

 

 

Behind the front, there was rapid clearing and much drier air filtered into the area. Winds shifted to the west and southwest at 15 to 20 mph with gusts over 30 mph in places.
