This bit of imformation is not hot off the press but thought I could bring it up and see what you all think. Here is a article released by the NWS on oct, 4, 07

"The National Weather Service (NWS) mission is defined as the provision of weather forecasts and warnings for the protection of life and property and the provision of weather information for the Nation’s economic well-being. The NWS previously issued and disseminated warnings for tornado, severe thunderstorm, flood and marine hazards using geopolitical boundaries. Realizing the continuing need to improve the specificity and accuracy of warnings for tornadoes, severe thunderstorms, floods and marine hazards, the NWS currently implements Storm-Based Warnings (as of October 1, 2007).

Storm-Based Warnings (threat-based polygon warnings), are essential to effectively warn for severe weather. Storm-Based Warnings show the specific meteorological or hydrological threat area and are not restricted to geopolitical boundaries. By focusing on the true threat area, warning polygons will improve NWS warning accuracy and quality. Storm-Based Warnings will promote improved graphical warning displays, and in partnership with the private sector, support a wider warning distribution through cell phone alerts, pagers, web-enabled Personal Data Assistants (PDA), etc. NOAA Weather Radios will work as before and continue to alert entire counties."

I understand why the NWS went with this "storm-based" warning system, but I'll tell you of why this didn't work before. I think it will work this time, but here's what can happen if it's done incorrect.

In the mid 90's, before our supercell outbreak in 1997, we had the same storm-based system in effect here in Michigan which took only parts of counties most affected by the impending storm. Needless to say one night, we had an outbreak of tornadoes that was not predicted (the tornado watch in question was until 5AM EDT so there was no chance to chase a storm such as this) and some of the warnings were for parts of counties that did not get, while others that were not DID get it.

The aftermath? An F-3 tornado hit Frankenmuth, Michigan in the dead of night causing tremendous amounts of damage. Put it this way, Frankenmuth is at least 40 miles north of where I am, and we had quite a lightning show ALL NIGHT LONG.

I'll leave with this point; I would never, and I mean NEVER chase a tornado in the dark. Dr. Josh and the rest of the crew have top-of-the-line radars and equipment, but for many amateurs doing something like that is just like playing Russian Roulette.
