Tornado Watch until 9 PM, Squall Line Slows Down...

As suggested in my last post, All of SE Louisiana is under a Tornado Watch until 9 PM.  Right now that does not include coastal Mississippi, but that will change shortly.  Unlike last week's line of storms, there have been numerous reports of wind damage to our west.

Along with briefly heavy rainfall and intense lightning, there have been many warnings issued for radar indicated tornadoes.   Remember with last week's tornadoes, we thought there was no great danger since there was no history of damage to our west.   Today there is so we need to pay attention for the next 4-6 hours until the line passes through.   SPC has us under high risks with the areas north of the Lake under greater danger.

As I mentioned previously, a potent upper disturbance over the Plains is the trigger with a split in the jet stream creating even greater lift right over us.

What has changed is the timing of the line of storms now projected to reach us between 8-10 PM.

As you can see, the line doesn't clear the Mississippi coast until near midnight.  Let's really pay attention during the 6-10 PM time frame.

We are in the warm air sector with high dew points (moisture) ahead of the front.  Things quickly calm down once the front passes.

No need to tell you we are under a high wind warning as gusts have topped 50 mph at the Lakefront airport.

We should see drier and slightly cooler air filter in behind the front with a weak upper disturbance bringing another shower chance on Saturday.  No real cold air is in sight, however, a stronger surge of the cold will arrive in the 8-10 day time frame.  Be prepared to react tonight if warnings are issued.  Stay safe & stay tuned!
