I wonder what pattern we were in when the cold event of 1989 happened. That was prob a one in a lifetime event. I think we were down to 11 degrees and had snow on the ground for nearly 2 days.
It was a La Nina
I was 13 at the time. And we left to go to central Louisiana (Marksville) to visit my grandparents. We came back home to busted pipes that burst through the attic. We had a lot of damage to our home. Had to strip all the carpet as well as replace the ceiling.
That's why I mentioned earlier that it just takes one event to make a memorable winter. Scott, I didn't realize 1989 was a La Nina year!
'89/'90 winter was actually a cool neutral ENSO winter, the year prior was a strong La Nina winter which saw many record highs during the winter. The interesting thing is that early November '89 was a very warm record breaking month for the gulf coast, then by the end of November into December the pattern started changing, similar to this year.
Could see the first freeze warnings of the season for far inland areas.
From LIX HWO:
"Cold air and high pressure will settle in Sunday night through Monday. Monday morning lows temperatures in the lower 30s will likely occur across Southern Mississippi and East Central Louisiana. A Freeze Warning may be issued late Sunday night into Morning morning. Freezing temperatures if they occur will only be a few hours at best. "
