Flash flood watch in effect beginning Wednesday



…A Flash Flood Watch is in effect from 7 AM Wed through 7 AM Thu for the northern half of Northeast Texas, Southeast Oklahoma, Southwest Arkansas and the northwestern third of Northwest Louisiana (See Graphic)….

…Severe Weather threat continues to increase for Wednesday for much of the Four State Region with a secondary threat possible on Thursday (See Graphics)…

…Additional Flash Flood Watches will likely become necessary later this week, encompassing the remainder of the Four State Region as the heavy rainfall shifts south of the I-20 Corridor of Northeast Texas and Northern Louisiana (See Graphic)… 

Timing and Overview:


The severe weather threat could begin as early as Wednesday Morning as we await a complex of thunderstorms to move our way from the west and northwest.  This threat will continue throughout the day with the excessive heavy rainfall threat likely continuing through the overnight hours Wednesday Night as well.


There will be another round of strong to severe thunderstorms across the eastern 2/3rds of our region on Thursday with periods of moderate to heavy rainfall in association with this cluster of storms as well.


Four State Impacts:

Impacts: Damaging thunderstorm wind gusts and large hail will be the primary threat Wednesday but an isolated tornado threat cannot be ruled out.  The same impacts are expected for Thursday as well for the eastern 2/3rds of the region.


The excessive heavy rainfall threat will likely continue through the the end of the work week and into the weekend for portions of the region (See Graphic).  Area lakes, rivers, creeks and bayous are at high levels at this time from previous rainfall.  This additional rainfall this week will likely result in additional rises and crests on our waterways unfortunately.
