Thunderstorms north of the city to diminish

A couple of lines of thunderstorms, some of which are severe over northwest TN, are moving along an outflow boundary north of the metro area. These storms are moving east, while developing along the southbound outflow boundary. At 9:30pm, the boundary is moving through Tipton County headed into the northern suburbs. More t'storms are expected to develop, but as daytime heating wanes, the possibility of severe weather diminishes significantly. By later tonight, storms themselves will diminish, but not until most of the metro receives some amount of rain (some local areas could see heavy rainfall). In addition, fairly gusty north to northwest wind will acommpany the passage of the outflow boundary and there will be plenty of lightning and thunder for the next few hours. By Saturday morning, a cold front will have moved through the region and we should be dry for most of the day. A hot but dry Father's Day is on tap.

Tornado!

The first half of 2008 has been a significant year in terms of tornadic weather in the U.S. Based on data from the Storm Prediction Center - the national authority on severe weather, the preliminary count of tornadoes so far this year is 1577 (the final figure usually ends up being about 70% of the prelim figure), which is almost 300 more than ALL of 2007 and more than any of the past 4 yearly totals! In fact, the yearly average number of tornadoes in the U.S. is 1000. Given the 70% actual to prelim ratio, we've already likely surpassed that average half way through the year.

The number of tornado deaths to date is also tragic - 118. That's more than 2005-2006 combined and a 46% rise from last year's total, and it's only June... It's also twice the average for an entire year. If you want to know more about tornadoes, visit the Storm Prediction Center's Tornado FAQ page at http://www.spc.noaa.gov/faq/tornado/. Unfortunately, we're smack in the middle of tornado season for the Upper Plains and Midwest, so a radical trend downwards anytime soon doesn't appear likely.
