MONROE, La. (KNOE) - The National Weather Service in Shreveport has released a new graphic that shows an expanded risk for severe weather in Louisiana and Arkansas. Severe weather is expected to impact Northeast Louisiana and Southeast Arkansas on Saturday morning, possibly during the overnight hours.
As of Friday morning, Jan 10, 2020, most of North Louisiana and all of South Arkansas are under 'Moderate' risk for severe weather. 'Moderate' is just one step from the highest risk level.
NWS says the potential impacts to worry about are damaging winds, tornadoes, large hail, and locally heavy rain.
The potential for tornadoes is listed at medium, one level below the highest level. Maximum hail size is listed at quarter to half-dollar sized hail. The maximum wind speed is listed at 80+ miles per hour. That's higher than the speed of a Category 1 hurricane.
According to the KNOE weather team, by Friday night, severe storms will be developing to our west in Texas and pushing toward Louisiana and southern Arkansas. And while we could have a couple of intense storms develop across the ArkLaMiss during Friday evening, most of the intense weather arrives overnight Friday into Saturday morning, roughly anywhere from 2 AM through 9 AM.
During this time, any severe storms that develop could produce damaging wind gusts in excess of 80 mph, tornadoes, hail and heaving rain. By late Saturday morning, the active weather is continuing to exit the ArkLaMiss.
