The threat of heavy rain and flooding late Friday into Saturday is increasing.
KSLA First Alert Meteorologist James Parish will track the heavy rain hour-by-hour with FutureTrack in the video below.
Area wide potential rainfall totals have increased from 1-3″ to 2-4″ of rain since Tuesday. The latest 5 day rainfall forecast from the Weather Prediction Center shows widespread rainfall totals between 2-4″ of rain. The heaviest rain will likely fall across deep E TX and western NW LA. This is where widespread rainfall totals of 4-6″ of rain will be possible.
Even though the forecast graphic above shows the 5 day rainfall forecast for Wednesday through Sunday, most of the rain will fall late Friday through Saturday morning.
Most of E TX south of I-30 and western NW LA will be under a Marginal Risk of excessive rainfall. This is where the heaviest rain will likely fall and where the threat of flash flooding will be greatest in the ArkLaTex. There is a Slight Risk of excessive rainfall just southwest of the ArkLaTex. The heaviest rainfall and greatest flash flooding threat will likely occur in the Slight Risk area.
A FLASH FLOOD WATCH will likely be issued for portions of deep E TX and, possibly, NW LA later this week.
The best chance of rain and the heaviest rain will likely fall Friday night into Saturday morning. The I-20 corridor and points north will have the best chance of rain Friday morning. The rain will spread throughout the rest of the area Friday afternoon and evening. However, the heaviest rain will sweep from west to east across the area Friday night into Saturday morning. The heaviest rain will likely wrap up Saturday afternoon.
There will still the potential for scattered wrap around showers Saturday evening into Saturday night. If the rain lingers long enough Saturday night, there will be the potential for a rain/snow mix or a few snow flurries north of I-30. No major accumulations or travel problems are expected.
