SHREVEPORT, La. (KTAL/KMSS) – 10:30 PM Update: The Severe Thunderstorm Watch is now expired in the ArkLaTex. The cold front is cutting off thunderstorms trying to develop in the warm sector. For the rest of tonight, we will see thunderstorms decreasing. Although, the rain threat is not over yet. Despite seeing some stable air north of Interstate 20, we are seeing more showers and thunderstorms developing. The storms will continue off and on for Monday. Finally, the upper low will push all of the rain out of the region. Through Tuesday evening, the ArkLaTex could see rainfall totals between 2-4″.
6:30 PM Update: The Severe Thunderstorm Watch is now extended to the south to include Interstate 20 and portions of Northwest Louisiana. Again the main impacts will be damaging winds and large hail. Although, an isolated tornado can’t be ruled out. Thunderstorms are continuing to grow in intensity to the west. Later tonight, the showers and storms will move into Shreveport Bossier!
Earlier Sunday, we did see a few thunderstorms reach severe limits in McCurtain County in Southeast Oklahoma. Over time, a line of showers and storms will slowly move to the south. As of now, the main concern is damaging winds and large hail. Although, an isolated tornado can’t be completely ruled out. The cold front will reach Shreveport-Bossier near 7-8 PM. Models are showing the line of showers and storms to really slow down near midnight. As the original line of storms weakens, the upper dynamics will lead to more rain late tonight into Monday. Along with severe weather, some flooding will be possible in spots. The region could see 2-4″ of rain but I am thinking higher totals will fall along and south of Interstate 20.
Monday morning is shaping up to be very wet. Temperatures will be cooler behind the front. Most of Monday’s rain will occur south of Interstate 30. Monday will not be a total washout but we will see more rain than not. As the upper low finally moves to the east, the rain will decrease from the west to the east on Tuesday.
Wednesday will be a nice dry afternoon with temperatures in the 60s. The active weather pattern will push another upper level shortwave through Thursday evening and Friday. The rain will come to an end Friday night. Next weekend is looking great! Despite a Pacific front on Friday, temperatures will be in the 60s and 70s.
