The Storm Prediction Center in Norman, OK has issued a Tornado Watch for all of SW Louisiana effective until 6a.m. Friday morning.This is an advance of a SW-NE oriented line of strong to severe thunderstorms moving to the SE across the state ahead of the cold front.
Other showers and thunderstorms have developed out ahead of this line, and very heavy rainfall has occurred around Lake Charles between 1 and 2a.m. Showers and thunderstorms will continue to become more numerous across the area ahead of the main squall line. One or two of these discrete storms will have the potential to reach severe limits with the main threats being large hail and damaging winds, but with the presence of a low-level Jet there is some shear in the atmosphere, and this is what is needed to produce tornadoes, so one or two tornadoes can't be ruled out overnight. I believe the main threats will continue to be from hail and high winds as well as heavy rainfall causing localized flooding. So far there have been no reports of severe weather in the area.
As of 2:20a.m. the main squall line was making very good progress into the area, and extends from near Columbus, TX to to Kountze, TX to Longville to Oakdale to to Marksville. It should be moving into Lake Charles around 3:30a.m. There are currently no warnings in effect, but if things change I will certainly keep you informed.Conditions will improve drastically once the MCS moves through, and and its on current pace it should be into Acadiana around 5a.m., clearing the forecast area by 8a.m.
