ARKLATEX (KSLA) - An Alert Day has been issued for Wednesday due to the potential heavy rain and flash flooding in the ArkLaTex.
A Flash Flood Watch has been issued for portions of eastern Texas, southeastern Oklahoma, and southwestern Arkansas. The watch starts at 6 p.m. tonight and will go through Thursday. This is due to the heavy rainfall expected the next few days. Rainfall totals in these areas could be 3-6+ inches. Places in Shreveport and southeast will see lighter totals.
A slow moving cold front will be moving throughout the region Tuesday evening and into Wednesday morning. Because the storm is slow moving, this is causing an increase in the flash flooding threat. A line of rain and thunderstorms will start to affect the ArkLaTex in the early morning hours on Tuesday and will continue to be heavy through the evening hours as well.
With a new run of Futuretrack, for tonight the northwest portions of the ArkLaTex will start to see heavy rain move into their area around dinner time. Cloudy skies persist into the rest of Texas, Arkansas, and Louisiana.
More widespread and heavy rain will move into Wednesday morning and will impact your morning drive. Make sure to give yourself extra time getting to work. Heavy downpours are expected.
Flash flooding threat increases as these heavy downpours continue throughout the entire ArkLaTex. These storms will be slow moving and flash flooding could occur within minutes.
This storm system will also be affecting your ride home from work. Heavy rain, along with the possibility of flooded roads, could make the drive difficult. Temperatures will continue to drop throughout the day leaving the northern portions of our area in the upper 40s and low 50s. The rest of the ArkLaTex will be sitting in the lower 60s.
Rain and storms continue throughout the evening hours of Wednesday but will start to clear out in the northern ArkLaTex by 8-9 p.m. Other areas should see a clearing of heavy rainfall late Wednesday and into the early morning hours of Thursday. Although the heavy rain will be moving out of the area, expect light to moderate showers to continue throughout your Thursday.
Rainfall accumulations vary from where you live in the ArkLaTex. Both models, the European and the American, are indicating the heaviest of rainfall northwest of Interstate 20. Cities here can expect anywhere from 3-6+ inches of rain.
As of Tuesday morning, the European model has continued its prediction of 3-6+ inches of rainfall. This model has also extended the area that the heaviest rain will fall. The European now shows heavier rainfall totals towards the Shreveport area. It now shows that most of Eastern Texas, northern Louisiana, as well as the area just north of I-20 in Arkansas and Oklahoma will see high rain totals.
As for the American model, it is still showing the heaviest rainfall northwest of Shreveport-Bossier. Both models agree that places southeast of the Shreveport area will see the least amount of rain and can expect 2-3 inches.
Our area is also under a moderate risk for excessive rainfall for Wednesday and into Wednesday night.
The main threat for this set of storms will be heavy downpours and the threat of flash flooding. This will impact your morning and evening commutes to and from work. Give yourself plenty of time to travel anywhere. Any roads, low-lying areas, or areas with poor drainage will be affected the most. The threat of gusty winds and lightning are low, but still could be a factor. If roads start to flood, do not drive through those area. Remember: turn around, don't drown! Just a few inches of water can make it difficult to keep control of a car.
The Storm Prediction Center has also put the northern parts of the ArkLaTex in a marginal risk for severe weather. The severe threat is low, but some of these storms could have some gusty winds associated with it along with the heavy rainfall.
