Severe Weather Update

* Still evaluating the threat of severe weather late Friday into early Saturday. Here's our latest thinking:

- Worst of the severe weather will be north and west of here, along an axis from roughly Shreveport, Louisiana to Louisville, Kentucky. This includes places like Greenville, MS; Memphis, TN; Jackson, TN; and Paducah, KY.

- Still too early to determine if we will see any supercells fire ahead of the cold front/squall line. If they do, our tornado threat could be pretty high, especially north of I-20.

- Even if we do NOT have supercells, I would imagine we will see some pretty significant thunderstorm winds. Wind speeds at 850 millibars (about 5000 feet above the ground) are forecast to be quite high (55-60 knots).

- Timeline of concern is from 1:00 PM Friday - 1:00 AM Saturday. We will probably adjust this timeline as we get closer to the potential event.

* I will post again early tomorrow morning after evaluating the latest data (around 8:30 AM).
