HWY316wx Posted February 29, 2012 Share Posted February 29, 2012 My mother in law and my 5 year old son are on I-75 just about 10 miles north of Knoxville as I type this. They are headed to Somerset, Kentucky. They will travel up I-75 to London, Kentucky. To say I am glued to the radar and the phone is an understatement.

Thrasher Fan Posted February 29, 2012 Share Posted February 29, 2012 Got my mother in law to stop in Corbin and not continue up to London. Family in Somerset is battening down the hatches. They should keep an eye on that storm just west of Jamestown, KY. That cell is becoming violent and should track close to Somerset. Link to comment Share on other sites More sharing options...

GREENWOOD 136 PM EST WED FEB 29 2012 ...SEVERE THUNDERSTORMS POSSIBLE LATE THIS AFTERNOON THROUGH THE EARLY MORNING HOURS ON THURSDAY ACROSS WESTERN NORTH CAROLINA..UPSTATE SOUTH CAROLINA..AND NORTHEAST GEORGIA... THUNDERSTORMS ARE EXPECTED TO DEVELOP LATE THIS AFTERNOON ACROSS EASTERN TENNESSEE AHEAD OF A COLD FRONT...WITH THE STORMS REACHING THE MOUNTAINS OF NORTH CAROLINA AFTER 6 PM THIS EVENING. THERE IS A GOOD CHANCE THAT SEVERAL OF THE STORMS WILL BE STRONG ENOUGH TO PRODUCE WIND DAMAGE AND LARGE HAIL. THE STORMS MAY CONSOLIDATE INTO A SQUALL LINE THAT COULD PRODUCE SWATHS OF DAMAGING WIND. THERE WILL BE ENOUGH WIND SHEAR IN THE LOWER PART OF THE ATMOSPHERE SUCH THAT TORNADOES WILL ALSO BE POSSIBLE. ALTHOUGH TORNADOES ARE RARE OVER THE MOUNTAINS...PARTICULARLY IN WINTER...THE WEATHER SITUATION THIS EVENING IS MUCH MORE LIKE SPRINGTIME...SO A FEW TORNADOES SHOULD NOT BE RULED OUT. ADDITIONAL STRONG TO SEVERE THUNDERSTORMS MAY DEVELOP LATE IN THE DAY ACROSS NORTHERN ALABAMA AND NORTH GEORGIA...REACHING NORTHEAST GEORGIA DURING THE MIDDLE PART OF THE EVENING. IF THESE STORMS DEVELOP...THEY WOULD MOVE ACROSS THE UPSTATE LATE THIS EVENING...AND TOWARD THE CHARLOTTE METRO AREA IN THE EARLY MORNING HOURS...PRODUCING DAMAGING WIND GUSTS AND LARGE HAIL. A FEW SUPERCELL THUNDERSTORMS WILL BE POSSIBLE...WHICH WOULD INCREASE THE THREAT FOR A FEW TORNADOES. IT IS UNCERTAIN IF STORMS WILL MOVE EAST OF THE BLUE RIDGE OVER THE NORTH CAROLINA FOOTHILLS AND NORTHWEST PIEDMONT...BUT THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS WITH DAMAGING WIND GUSTS IN THOSE AREAS LATE TONIGHT. LATER DEVELOPMENTS...SUCH AS THE DEGREE TO WHICH THE ATMOSPHERE BECOMES UNSTABLE AND THE AMOUNT OF WIND SHEAR...WILL DETERMINE IF ANY SEVERE THUNDERSTORM OR TORNADO WATCHES ARE ISSUED FOR THE WESTERN CAROLINAS AND NORTHEAST GEORGIA. MONITOR THE FORECAST LATER THIS EVENING...ESPECIALLY BEFORE GOING TO BED TONIGHT...TO SEE IF SEVERE WEATHER MIGHT BE DEVELOPING. TORNADOES CAN BE MOST DANGEROUS LATE AT NIGHT WHEN PEOPLE ARE SLEEPING AND DO NOT HAVE A WAY OF RECEIVING WARNINGS FROM THE NATIONAL WEATHER SERVICE. $$ MOORE Link to comment Share on other sites More sharing options...

Marion_NC_WX Posted February 29, 2012 Share Posted February 29, 2012 Looking the CAPE last hour and other features, I think this cluster may ramp up once it enters Eastern Tennessee. The CAPE in particular looks better over East Tennessee and crossing into far Western North Carolina. Link to comment Share on other sites More sharing options...

on_wx Posted February 29, 2012 Share Posted February 29, 2012 Not really impressed right now with this crap moving through Nashville. I'd blame CNN. They've been calling for tornadoes of death and doom all afternoon -- even at times saying more deaths will happen today. They even have that little hurricane tracker window on the screen tracking radar. Link to comment Share on other sites More sharing options...

WeatherNC Posted February 29, 2012 Share Posted February 29, 2012 Harrisburg IL was an EF4, the pic of the cash store in a shopping complex was impressive to say the least, structure had steal supports ad those were basically collapsed. Large steal beam just dropped in places, violent tornado. Anyone noticing this line maybe taking on a more discrete appearance as it moves into E TN, can count 3 or 4 cells not nearly as embedded compared to an hour ago.

OceanStWx Posted February 29, 2012 Share Posted February 29, 2012 And a very discrete supercell that just passed close to Smithville, TN. High reflectivity at the tip of the hook, but correlation coefficient suggests this is precip. Link to comment Share on other sites More sharing options...
