downeastnc Posted April 29, 2014 Share Posted April 29, 2014 Wow Wilson has 49,000 residences. Most of Wilson is west of I 95 and the couplet looks to slip tio the east and eastern Wilson Co is pretty much farm country...... edit: newer couplet forming SW of Wilson that could be big trouble Link to comment Share on other sites More sharing options...

You can see this well on the SPC site, that's what some have been saying regarding advecting those steeper rates in. There is no question steep mid level lapse rates allow for explosive development of supercells and allow for violent updrafts to help sustain long track storms. However good CAPE in the 0-3km will allow for low level stretching and tornado development too...but perhaps not as strong or long track as what you would see with more of an EML present. That's kind of the wild card we have now. Link to comment Share on other sites More sharing options...

Ground Scouring Posted April 29, 2014 Share Posted April 29, 2014 Significant further development of / potential for strong tornadoes in srn and s-ctrl MS will likely wait for a couple more hours before mid-level lapse rates finally steepen enough to allow for such development. Temperatures are well into the 80s over in LA, SW of the MDT Risk area, which may also help develop a hint of a mesolow along the gradient over near the Red River in LA, thereby bolstering low-level helicities a bit. (Or would the hint of a mesolow not develop? Please feel free to correct me.) Link to comment Share on other sites More sharing options...
geddyweather Posted April 29, 2014 Share Posted April 29, 2014 Funnel Cloud reported about 15 miles south of Rocky Mount, NC. These North Carolina storms have taken me by surprise...

A COUPLE TORNADOES POSSIBLE ISOLATED DAMAGING WIND GUSTS TO 70 MPH POSSIBLE ISOLATED LARGE HAIL EVENTS TO 1.5 INCHES IN DIAMETER POSSIBLE THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 75 STATUTE MILES NORTH AND SOUTH OF A LINE FROM 40 MILES WEST NORTHWEST OF TUSCALOOSA ALABAMA TO 30 MILES NORTHEAST OF GADSDEN ALABAMA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS...
