Severe Weather Outlook for Arkansas from the National Weather Service in Little Rock

A few strong to severe thunderstorms are possible across western Arkansas Wednesday evening and Wednesday night.

Scattered showers and thunderstorms will be possible today across the region into this evening. Late tonight, strong to severe thunderstorms will be possible mainly northwest of the region. Look for strong south winds today outside thunderstorms with wind gusts upwards of 30 mph possible. There will continue to be an elevated fire threat due to very dry conditions with those conditions continuing until rainfall materializes later today into Thursday.

A few strong to severe thunderstorms are possible across eastern and southern Arkansas Thursday.

In SW AR, rain chances will continue through the end of the work week, into the upcoming weekend and into early next week as well. At this time, strong to severe thunderstorms do not appear likely through early next week. Temperatures will remain mostly above normal through the extended period as well.

The forecast for Halloween evening calls for rain chances across the southeast with dry conditions elsewhere. Temperatures will largely be in the 50s and 60s.

More rounds of showers and thunderstorms for Arkansas into Friday; weather briefing from the National Weather Service in Little Rock

A front will be nearly stationary across southern Arkansas through at least Friday. Scattered to numerous showers and thunderstorms will surround the front Wednesday and again Friday.

Storms that become severe will be capable of producing very large hail and damaging wind.

A new cold front will arrive from the Plains late Saturday into Sunday. Another round of strong to severe thunderstorms will likely accompany the front.

Late in the weekend and early next week, precipitation will become more spotty and it will heat up. Heat index values will likely exceed 100 degrees, mainly from Little Rock southward.

Severe weather and heavy rainfall possibilities for the southern half of Arkansas through Wednesday

A front will be nearly stationary across southern Arkansas through Wednesday. Scattered to numerous showers and thunderstorms will develop near the front, with precipitation concentrated over the southern half of the state.

Storms that become severe will be capable of producing damaging wind and large hail in places.

Areas of heavy rain are expected, with two to more than three inch amounts across the southern counties. Given this much rain, there is a possibility of flash flooding.

NWS-Little Rock warns of a strong storm system in Arkansas on Friday, March 31

A strong storm system will be in the central United States on Friday.  Ahead of the system, a gusty south wind will bring warm temperatures and increasing moisture, and the potential of strong to severe thunderstorms. 

The greatest severe weather potential is where the most lift (surrounding a storm system to the north) overlaps the most unstable air (from the southwest). This includes northern Arkansas.  Where severe storms develop, the main concerns will be damaging winds and hail, and there may be isolated tornadoes.

Quarter to three quarter inch precipitation totals are in the forecast, with up to an inch in the north. This will not be enough to make existing high water issues (i.e. elevated rivers/saturated soil) worse.

Over 75 million people in central US at risk of severe weather outbreak - Accuweather

At least 15 states will be at risk of an outbreak of violent thunderstorms that will unleash everything from damaging winds to tornadoes on Friday, AccuWeather meteorologists warn. The area highlighted by forecasters is a massive swath of the country that extends from Texas to Alabama in the South to areas farther north such as Wisconsin and Michigan.

The AccuWeather forecast team raised Friday’s risk of severe weather from moderate to a high level prior to the middle of the week, a sign of growing concern for the potential damage the storms could cause.

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.

...FREEZE WATCH IN EFFECT FOR SW ARKANSAS AND SE OKLAHOMA FROM LATE FRIDAY NIGHT THROUGH SATURDAY MORNING...

* WHAT...Sub-freezing temperatures as low as 32 possible.

* WHERE...In Arkansas, Sevier County, Howard County, Little
  River County, Hempstead County and Nevada County. In Oklahoma,

* IMPACTS...Frost and freeze conditions could kill crops, other
  sensitive vegetation and possibly damage unprotected outdoor
  plumbing.


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 for Arkansas Wednesday and Thursday

Scattered to numerous thunderstorms will begin moving across the region on Wednesday, with some storms capable of producing hail and strong wind gusts. On Thursday, another round of strong to severe thunderstorms will be possible from late afternoon into the overnight hours when large hail, damaging winds, and tornadoes will all be possible.

Storms and gusty winds expected for Arkansas on Wednesday

A system will be moving through the region on Wednesday which could bring a few strong storms to the area but the overall threat appears to be minimal. The greater concern may be the strong winds that will accompany the system outside of any thunderstorm activity.

Severe weather possible in Arkansas on Wednesday

A few strong to severe storms are possible from Wednesday into Wednesday night, especially across eastern, southern, and southeastern Arkansas. 

Widespread Shower and Thunderstorm Activity Is Expected Across SW Arkansas Thursday

Showers and thunderstorms will become widespread across much of the state Thursday and Thursday night. While severe weather chances remain low, some storms could produce locally heavy rainfall and gusty winds.

Heat indices across southern Arkansas could approach or exceed 100 degrees in some locations Thursday afternoon.

Widespread showers and thunderstorms will persist across roughly the southern half of the state on Friday. Severe weather chances will remain low, but a few storms could produce locally heavy rainfall and gusty winds.
