Cheeznado Posted February 28, 2011 Author Share Posted February 28, 2011 Looks very interesting especially in eastern AL and west GA this afternoon.

Gastonwxman Posted February 28, 2011 Share Posted February 28, 2011 Tornado Watch coming out for good chunk of N AL/GA into TN West SC/NC. The NWS Storm Prediction Center has issued a Tornado Watch for portions of central and northeast Alabama northwest Georgia western North Carolina upstate South Carolina southern middle and eastern Tennessee Effective this Monday afternoon and evening from 130 PM until 800 PM EST. Tornadoes... hail to 1.5 inches in diameter... thunderstorm wind gusts to 70 mph... and dangerous lightning are possible in these areas. The Tornado Watch area is approximately along and 110 statute miles east and west of a line from 50 miles north of Hickory North Carolina to 50 miles southeast of Tuscaloosa Alabama. For a complete depiction of the watch see the associated watch outline update (wous64 kwns wou3). Remember... a Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Other watch information... this Tornado Watch replaces Tornado Watch number 31. Watch number 31 will not be in effect after 130 PM EST. Continue... ww 32... Discussion... storm coverage/intensity should increase through the afternoon along and immediately ahead of a weak surface wave across middle TN... and in advance of a midlevel trough over nrn MS/wrn TN/wrn KY. The storm environment remains favorable for supercells and a few tornadoes across se TN/al/NW GA per the 18z bmx sounding. Farther N... storms in ern TN will develop ewd into NW NC... along the outflow boundary from the earlier convection that crossed into VA. Instability will be a little weaker than areas farther SW... but vertical shear remains strong... and the potential will remain for embedded supercell structures. Later during the afternoon... convection is expected to evolve into more of a linear system with a threat for damaging winds and brief spin ups along the bowing line segments. Aviation... tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 26045. Link to comment Share on other sites More sharing options...

audioguy3107 Posted February 28, 2011 Share Posted February 28, 2011 Temps have really shot up here....we've been in bright sun for about 30 minutes and we've gotten up to 74. Winds gusting from the SW.......keep your eyes on the radar to the SW, especially south of the BMX area. Should start seeing some things pop any time now.

DrOldSchool Posted February 28, 2011 Share Posted February 28, 2011 Hello everyone, long time reader first time poster, and wanted to log a report. I work at the U of Tennessee and have a view of the downtown area that most are jealous of from my 11th floor office. On a clear day I can see the mountains off in the far distance and all of the downtown skyscrapers, the Sunsphere, and into Neyland Stadium. Earlier this morning (roughly 10 AM) when I arrived in the office, I was watching a convergence overhead with light thin clouds to the South of the city and heavy rains North of I-40. The storm picked up around 12:40 and we had pea-sized hail for a few minutes. I walked my half-mile walk back from teaching at 1 PM as the rain picked up and I am a soaked more than a sponge, even though I had an umbrella. It was quite a torrential rain for about 30 minutes during/after I came back (1:00-1:30). During that period I could not even see Neyland Stadium (except for its lights), let alone downtown or beyond out my window. As I have been typing it's picked back up again and the downtown is slowly disappearing once again. The local news is showing images of heavy flooding blocking lanes on I-275 and on US-441 among other local streets. Link to comment Share on other sites More sharing options...
