The THV11 Weather Team will be busy through Thursday as three rounds of storms look likely to move across the state. Very heavy rain is possible within a short period of time and could lead to significant flash flooding of small creeks, low lying areas and poor drainage areas.

The National Weather Service has posted a Flash Flood Watch until Thursday morning for most of central Arkansas.

Most of central Arkansas could see 2 to 4” of rain in the next couple of days. Higher amounts expected in southern Arkansas. I would not be surprised to hear some locations getting 7 or 8” of rain from this event.

The map below shows the rainfall totals expected through Saturday.

Remember to never attempt to drive through a flooded road. You don’t know how deep it is and the road may be damaged or washed away.

A foot of water can float many vehicles; not to mention–why take a chance of ruining your vehicle?   

Along with the threat of heavy rain is the chance of strong to severe storms. The main threats will be damaging straight-line winds and brief weak spin tornadoes embedded within the line. Except for southern areas of the state where the threat is higher.

TIMELINE: Here is what to expect

3 rounds of storms

KTHV

ROUND 1:

A line of strong to severe storms with heavy rain will approach western areas of the state between 8 a.m. to 1 p.m. This line will arrive in most of central Arkansas between 11 a.m. at the earliest to 3 p.m. at the latest. Areas east can expect the storms to arrive in the afternoon. Severe weather threat should be over by 8 p.m. for the state.

Main threats along the line are damaging straight-line winds, and brief tornadoes. Hail is also possible.

ROUND 2:

Storms will fire up again while you are sleeping Wednesday night into early Thursday morning. This line will also have the potential to produce very heavy rain, damaging winds, a higher threat of tornadoes, and hail. Thursday morning commute could be messy. Storms should be done by mid-morning.

ROUND 3:

As a cold front enters the state, if we clear out Thursday afternoon, the atmosphere could recover and new storms could fire up ahead of the cold front.

The main threats will be large hail and tornadoes with a few storms, but this threat is conditional.

TORNADO RISK:

The threat for a brief spin-up tornado embedded in the line of storms Wednesday and Wednesday night is low for most of the state in the yellow area.

However, the ingredients are expected to be in place for a better chance of more significant tornadoes in the orange area both Wednesday and Wednesday night.

Make sure you have a way of getting warnings and watches, especially when you are sleeping. The THV11 Weather Team will be here around the clock until the threat passes, keeping you updated.

Have your shoes in a place where you can find them easily if needed, know where your pets are and can be quickly taken to safety, and any important documents may need to stored in a closet or a safer location, if possible.
