SluggerWx Posted February 28, 2011 Share Posted February 28, 2011 FWIW, CAP broke in Nashvegas today about 3 PM...a few clouds tried to organize but I could still see stars when I went to get some groceries at Publix 30 minutes ago... Not many folks talked about Nashville last Thursday (re: potential to develop severe storms), but I'd say we're going to see something very significant in my local and surrounding areas over the next 36 hours. BTW, we've got that 'pre-hurricane' bath-water air feeling going on currently (went outside). EDIT* On second thought, maybe I don't know as much about 'CAPS' as I thought? All that insignifcant rain showing on the Nashville RADAR would suggest a CAP does exist, correct? Link to comment Share on other sites More sharing options...
SluggerWx Posted February 28, 2011 Share Posted February 28, 2011 Muggy up here - temps continue to rise. Believe storm initiation should be within the next 1-2 hours in our area. Defin has been a long day watching and waiting. 850 winds are picking up and should really pick up over the next few hours. Seems like these bigger events are like this - hurry up and wait. Beau, BTW, just want to thank you for all your expertise. From Easternuswx over to here, I've always appreciated your guidance and analysis.
