Severe weather risk for Arkansas Thursday and Friday

A strong storm system is expected to bring showers and thunderstorms to the state Thursday through Friday night. Some of these storms could become strong to severe. In addition to the threat for severe weather, there is also a threat for flooding due to the expected heavy rainfall. Please see the attached briefing for more details.

There is a Marginal Risk for severe thunderstorm late on Thursday into early Friday, along and mainly north of our I-30 corridor. Damaging winds and large hail will be the primary threats and locally heavy rainfall could bring isolated flash flooding.

Locally heavy rainfall from a line of strong to possibly severe thunderstorms, could result in isolated flash flooding late Thursday into early Friday with the Slight Risk north of our I-30 corridor.

Severe Weather Briefing for Arkansas on Thursday; Freeze watch also in effect for the weekend

A round of showers and thunderstorms will move across the state later today into tonight and some of these storms could become strong to severe. Damaging winds will be the primary hazard.

Showers and thunderstorms will begin to increase late this morning in Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and even Northwest Louisiana by early this afternoon. All of this well ahead of a strong cold front and associated upper level disturbance that will approach the region from the west tonight. An isolated severe threat exists with these afternoon storms with large hail possible, but the majority of our severe weather threat will hold off until late this afternoon as the warm front comes into play. Then the thunderstorms gradually become more surface based moving eastward and better organize ahead of the strong cold front as it moves across I-30 this evening. The thunderstorms will merge into a potent squall line, while moving southeastward ahead of the cold front this evening. Large hail, damaging winds, and isolated tornadoes are the main threats late this afternoon and on through much of Thursday night, before diminishing in the predawn hours. Locally heavy rainfall will also be possible with 2 inches or more in the stronger storms, which may result in minor flooding of our low lying and poor drainage areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Take steps now to protect tender plants from the cold. To prevent
freezing and possible bursting of outdoor water pipes they should
be wrapped, drained, or allowed to drip slowly. Those that have
in-ground sprinkler systems should drain them and cover above-
ground pipes to protect them from freezing.

Severe Weather Briefing from the National Weather Service

The threat for strong to severe thunderstorms will exist Sunday afternoon and evening across the Four State Region along and ahead of a weak cold front that will shift southeast into the area. Damaging winds, large hail, and locally heavy rainfall will be the main threats with these storms, before they gradually diminish Monday morning. However, additional showers and embedded thunderstorms will become more numerous across the region Monday night through Wednesday north of the front, with the threat for heavy rainfall and localized flooding of low lying, poor drainage areas possible.

Arkansas Forecasted Rain For the Week from the National Weather Service

Showers and isolated thunderstorms will return to portions of the region today, generally north of the Interstate 30 corridor near a stationary cool front. By this evening, the front will start to slowly push southeastward, bringing increased rain chances to Southeast Oklahoma, adjacent southwest Arkansas, and portions of East Texas. Although the overall threat for severe weather is limited, the Storm Prediction Center has issued a Marginal Risk for these same general areas, with a Slight Risk for the extreme western sections of McCurtain County Oklahoma and Red River County in Texas. Damaging winds and large hail are the main threats. Also, these same locations could see locally heavy rainfall. Localized amounts up to 3 inches will be possible, which could lead to a some isolated flash flooding. In addition to the rain, expect winds to increase today from the south to near 15 mph, with gusts up to 25 mph. A Lake Wind Advisory is in effect from 9 AM to 7 PM this evening, as strong winds will create hazardous conditions on area waterways.

Rain chances will continue to spread across the entire area, as a cool front slowly moves across the region Thursday into Friday morning. Although the overall threat for severe weather is limited, a few strong thunderstorms cannot be ruled out, with locally heavy rainfall possible. Some slightly cooler and drier air will filter into the area in wake of the front, but rain chances will return for the weekend, as an upper level trough moves across the region.
