Friday Evening Thoughts...

* The 0z (Evening) NAM run is in, and continues to support the idea of a line of severe thunderstorms racing through our area tomorrow evening. Here are some important parameters from the latest run, valid at midnight Saturday night:

CAPE: 680.6 J/kg

0-3 KM SRH: 480.6

850mb Winds: 53 kts (or 61 mph)

* Our thinking hasn't changed since earlier today: A line of strong to severe thunderstorms will push through the area tomorrow night, sometime between 4pm Sat. and 2am Sunday. There is some chance that individual cells could fire ahead of the squall line. If that occurs, the threat of severe weather could arrive earlier Saturday afternoon.

* The main threat will be strong straight line winds....Winds aloft are forecast to be quite powerful, and some of those winds will be transported to the surface by thunderstorms. Even outside of the storms, winds tomorrow will be quite gusty, on the order of 20-30 mph.

* Lauren Raymer and Chris Whited will join me at Newscenter 11 tomorrow to watch this situation evolve...We will keep the blog fresh and will also update you on television as the situation warrants...
