LithiaWx Posted June 28, 2011 Share Posted June 28, 2011 Once that line of storms hit the crapvection in Northern Alabama it lost all it's punch. Meanwhile the outflow that came through here earlier this morning is sparking storms to my south. Link to comment Share on other sites More sharing options...

Looks like the rain is finally making headway into No. GA. Link to comment Share on other sites More sharing options...

GreensboroWx Posted June 28, 2011 Share Posted June 28, 2011 Our 60% chance this afternoon was just lowered to 30% Yeah, but you have a 70% chance tonight. You'll prob have to wait for the storms to drop down from the mountains. Don't worry, the atmosphere appears primed! Link to comment Share on other sites More sharing options...
NEGa Posted June 28, 2011 Share Posted June 28, 2011 i hope we get more storms today. this pattern, while hot, has at least been giving us the afternoon storms again that have been missing for so many summers. i am not looking forward to the pending heat wave as if it isnt hot enough already Link to comment Share on other sites More sharing options...

Don't worry, the atmosphere appears primed! Perhaps - but things are slow to develop here in the mountains as well. Certainly not yet widespread showers/storms yet. Kinda wondering if they will materialize given the massive MCS that is still ongoing across the south. Seems to me the front will actually "jump" the mountains and focus convection further east across the Piedmont. This is what the 12Z NAM was hinting at...

Seems to me the front will actually "jump" the mountains and focus convection further east across the Piedmont. This is what the 12Z NAM was hinting at... thats what I'm wondering. This area is sandwiched between 2 areas of strong convection, but this means also our instability is growing by the second and has a lot of unworked air. A weak lee trough is in place and with outflows increasing, I'd think somewhere in the piedmont between Athens or even central GA and Greensboro a mass or several clusters of thunderstorms could still develop this evening.

MotoWeatherman Posted June 28, 2011 Share Posted June 28, 2011 I'm losing hope for convection IMBY and across far north GA. A few storms have popped in far NE GA but that's about it. Totally socked in with high clouds and my temp is only 79. Glad I got that peanut sized storm last night. It could still happen but the outflow from that MCS in Alabama that blew thru here earlier this morning might have put a damper on the atmosphere.

FoothillsNC Posted June 28, 2011 Share Posted June 28, 2011 just looked at the European and its much cooler for the Southeast this weekend, versus GFS. Both aloft and the surface. Both models have a Bermuda ridge forming around days 7 through 10, thats far out, but both have the ridging shoving back west, with a weakness in the Gulf states/Gulf, with the northern stream far removed. So thats a time frame to watch something in the Gulf get pulled north into the Southeast from the western Carribean. Link to comment Share on other sites More sharing options...
