000 FXUS62 KFFC 212022 AFDFFC AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 422 PM EDT TUE JUN 21 2011 .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... PRIMARY CONCERN AGAIN IS CHC FOR SEVERE CONVECTION WED AND THURS. STORMS HAVE MANAGED TO DODGE CWA THIS AFTERNOON...NO ONE SEEMS TO BE COMPLAINING OTHER THAN THOSE WISHING FOR SOME RAIN. MODELS STILL IN GOOD AGREEMENT TO UPPER TROUGH WILL SLOWLY PROGRESS EAST REST OF THIS WEEK AND SOUTHERN FRINGE OF WESTERLIES WILL DIP INTO ALL OF NORTH GA. EXPECT STORMS IN AL TO WEAKEN THIS EVENING BUT STORMS FURTHER WEST TO PERSIST OVERNIGHT AND CONTINUE EAST INTO NW GA AFTER SUNRISE. THIS SCENARIO DEPICTED BY MOST MODELS INCLUDING 12Z GFS/15Z SREF MEAN/12Z ECMWF. 12Z AND 18Z NAM STILL ODD MEN OUT WITH NO INDICATION OF OVERNIGHT CONVECTION TO THE WEST...ALTHOUGH 18Z NAM DOES FIRE IT UP IN THE MORNING OVER NW GA. HAVE BUMPED POPS UP FOR LATE TONIGHT AND WED FOR NW 1/2 OF CWA. IF ENOUGH CLOUDS AND PRECIP CAN COME THROUGH IN THE MORNING...THIS WOULD DECREASE INSTABILITY AND LOW LEVEL FORCING AND HOPEFULLY JUST GIVING US SOME NEEDED RAIN. IF CONVECTION AND CLOUDS DISSIPATE IN THE MORNING...COULD BE IN FOR SOME REALLY ROUGH WEATHER AS VERTICAL WIND SHEAR WILL BE UNSEASONABLY STRONG. 0-6KM BULK SHEAR STILL PROGGED AT 20-25KTS. DAMAGING WINDS WOULD BE THE PRIMARY THREAT...BUT AGAIN DEPENDS ON EVOLUTION OF OVERNIGHT AND MORNING CONVECTION. FOR NOW...NAM THE ONLY MODEL REALLY SHOWING THIS. WILL HAVE TO WAIT AND SEE. AS WAVE MOVES SLOWLY EAST THURS...FLOW ALOFT OVER GA BECOMES MORE WESTERLY THAN SW AND A TAD WEAKER. MAY BE A LITTLE LESS COVERAGE OF STORMS AS RIBBON OF DRIER AIR WRAPS IN FROM THE WEST OVER NORTH GA. HAVE CONTINUED CHC POPS WITH PLENTY OF MOISTURE AND INSTABILITY OVER ALL BUT FAR NORTH GA. USED BIAS ADJUSTED MET GUIDANCE AND RECENT PERSISTENCE FOR MIN TEMPS AND BIAS ADJUSTED MAV/MET FOR MAX TEMPS. .LONG TERM /FRIDAY THROUGH TUESDAY/... WEAK UPPER TROUGH AXIS STILL PROGGED BY MED RANGE MODELS TO REMAIN OVER THE SOUTHEAST THROUGH TUESDAY. 12Z ECMWF A LITTLE FASTER PUSHING IT OUT BUT VERY LITTLE DIFFERENCE BETWEEN IT AND 12Z GFS AND GEFS MEAN. SHOULD KEEP US IN FAIRLY ACTIVE PATTERN WITH SCT DIURNALLY DRIVEN STORMS IN THE AFT/EVE WITH NEAR OR SLIGHTLY BELOW NORMAL MAX TEMPS. MIN TEMPS SHOULD STAY WARM. GOING FCST LOOKS GOOD AS 12Z RUNS NOT MUCH DIFFERENT THAN 00Z RUNS. SNELSON

Nice AFD!!! I like the wording. :thumbsup:

I think Wednesday storm chances are pretty good, atleast 50 % or greater , in the green shade, or thats the area of concentration, like today's area was mostly lined up initially west of there and developed east and northeast nicely. The models have good moisture to work with, a few vorts moving in, divergence aloft and with good gulf inflow and heating, the stage is set. Don't think everyone will get wet, but coverage should be pretty high, compared to what we've seen lately. The NAM wants to do this tonight, with big rains moving into the Carolinas and eastern GA, but not sure why, and doubt that. (but the radar is increasing for those areas now). Overall the front to our west should begin slowing and draping west to east eventually, with plenty of moisture in place and slightly cooler temps, so it will be much easier to instigate development.

y;eah I watched the outflow race from Polk and Rutherford south to about 85 in Spartanburg, then it hit another outflow and popped a storm over upper Spartanburg to here. That used to be pretty common, its small but I can hear it. Getting close bolts now.

After my last post I went after another cell that popped and held longer but unfortunately I was blocked by the restricted area of Ft. Bragg and I was already starting behind it. Anyway Robert as always your reasoning is sound and makes sense. Now that I will be working full time as a met after this week I will be re-launching my website and making forecasts again (being I will be able to spend more time looking at models etc.).

Indeed. The smoke is really bad here in Cary. Can barely see a quarter mile, and it seems to be getting worse. Is this smoke from the fire on the coast or the fire in pender county or both?

Yes BOTH, it's Located in holly Ridge/Shelter Game area, over 3300 acres burning, I noticed it yesterday from the pier in Carolina beach.

Keeping my eye on the activity currently crossing through Abbeville and Greenwood, SC. If that's able to hold on, I believe that will bring more rain and storms for Upstate SC and parts of Southern NC for tonight. Large area of severe thunderstorms clustered in there and progressing northeastward, nearing the I-26 corridor.

You'll probably get the one thats getting me now. It just developed over Blacksburg, one minute the sun was out after the first one, and now this one developed right over head. It began with a bolt from the blue, which scared the ** out of me. Pouring again. Small, but nice rainmakers.

Just got put under a severe thunderstorm warning here. The clouds out here looked as though they would depart northeast but I've been noticing redevelopment to my southwest, which is now looking more threatening out here with darkening skies and distant thunder. I'm also getting into a nice breeze out here so something may end up affecting me if this continues. Had a tremendous triple bolt lightning strike nearby as well, which was totally unexpected.

Listening to the storm over Four Oaks riding up I-95. I bet the lightning would look awesome after dark with all this dense smoke. Cannot make out any kind of cloud structure today.

Solak representin' Central NC! Hopefully, those storms just to the south can propagate some good outflows up this way enough to spark come convection for us. Looks like storms are gradually forming a bit farther north. I can't wait for the sun to go down....for the reason you mentioned.

the lightning, as usual, is pretty impressive . Its been non stop thunder (well every few seconds) for about an hour and a half. Just when i think its ending, a new cell clips me. Pouring again, this time with a lot of wind, didn't have any earlier. This makes 3 distinct cells to get me.

I only received a little from the first cell and that's it, not even a tenth of an inch.

yeah , I watched the radar closely, I'm not that lucky with the rain so far, it never lasts long, but the in cloud lightning show is increasing now, and I just felt a really warm wind blow in from the southwest. Strange. Funny things happen with these small cells are just forming. I'm curious to see what the next wave does approaching from the south. You can see a strong outflow preceding it, we may feel that eventually.

Hopefully we can catch some rain from that, although I really don't want much wind. Still have some limbs down from the storms on Saturday. Never had this much damage to trees and outside chairs, tables, etc.

Pretty sure I just watched a small supercell form and get gobbled up by the convective mess behind it. In the past 30-45 mins moving northeast, just east of Reidville, SC in Spartanburg County. I don't see how because the shear is about non existent, but I know a supercell when I see it. I guess there were some mesoscale influences and interactions that weren't being picked up. Well I can't wait to get these time lapse vids and pictures up. What an epic win out of nowhere. Looking back at the radar loop, there was some cyclonic rotation... very broad.

just got back online after being slammed with trojans/viruses. Watch out, apparently a lot of my FB friends got hit at the exact same time. Meanwhile, while my PC was doing its thing over the last hour, i went out to video the awesome lightning. I'll post it soon as i can. I may not be out of the woods on this virus mess enough , lol, so if i disappear, you'll know why. The in cloud lightning was up close and I have several good vids I think.

How did your computer behave and do you remember what sites you were on before you realized you had the infection? I've been getting a keylogger on mine, which has caused me more than enough trouble with an online account that I have but managed to erase it through Spybot (great program to use by the way). Anyway, the lightning here was about how you described it. Just amazing. Currently working on a video with clips of the best ones.
