Once again the Euro is taking its lead from the very consistent GFS model. No longer does it have the huge Southeast heat wave this weekend, instead has a slight one early next week. With both models keeping ridging in central Canada, its similar to split flow, so a branch of the westerlies should continue to carry impulses west to east, and topping the ridge somewhere into the Carolinas for the next 5 to possibly 7 days, before both models have a fundamental pattern change. So nothing really has changed in my thinking froma few days ago, the waves or MCC developments should develop like we're seeing now in TN, but not everybody will get them unfortunately, and some areas will get them repeatedly. I think eastern TN and nw NC are likely to have the best shots at the most rain and probably eventually the 77 corridor later this weekend in NC around CLT to GSO/INT as we've seen many times this season a pattern of convection either form in the mtns or propogate from west of the mtns and drift into that region. Thats also another reason I think temps will be kept in check in the CArolinas, with much more ground moisture in the foothills to western piedmont, plus the big heights never arrive here (even through 10 days)..and models tried erroneously to heat up CLT area too much with the previous heat wave. Looks like the GFS shows daily convection in the lee side of the Apps, which also fits whats been happening, before the next big change.

West of the Apps, big heat but the worst is around TX to ARK and western TN, and not too long lasting b/c we can see a big change with a large central trough showing up by day 7 and that will potentially pick up a chunk of Gulf moisture (don't know about tropical yet) and dump it into the midwest , and maybe the Southeast , but thats out too far in time. The GFS has been showing a slow moving system in the Gulf for several runs as Dan mentioned, some runs had over 20" of rain.

yikes.png Bad timing with the current system moving in.

thats for sure...hopefully they can get it back up soon. looks like your calls from earlier are falling into line, and noticed the storm watch out, thats why i love the board so much :) of course after being narrowly missed multiple times the last week i am wary that mby gets any rain :lol:

its was gorgeous last night and this morning with low humidity and a nice breeze.

Robert...do u realize what you said in the first sentence! HaHa! You can tell its not wintertime...lol!

yep, I know..but its true. I've got a lot of archived model runs and most of them showed indeed the GFS wins big over the Euro since January. Weird. But its patterns make sense and the Euro's a lot of time doesnt' lately, so until I see a reason to, I wouldn't diverge much from it. Used to be the complete opposite though. Anyway,looks pretty active soon for ga and NC. Also later tonight for SC and probably central GA and central Al.

Does it look to be widespread storms tonight? Or just certain areas going to get rain?

NWS Blacksburg

WRF-arw has the center of this complex coming across northwest North

Carolina (watauga-ashe) between 8p-11p. Model cape values 400-800

j/kg exist across the mountain Empire...New River valley and into

the northwest North Carolina foothills until midnight. RUC surface

analysis at 18z not to impressed with cape values over the area.

Current thinking is that scattered strong to severe weather is

possible for the southwestern portion of rnk County Warning Area...but may not need

a watch. We will continue to monitor the weather and update as need

through the night.

looks like most of central and western NC overnight gets hit hard, but the convection is going to fight dry and lower dewpoint air esp. where you are, but further south near GA,NCSC borders will probably ramp up to severe. The entire wave is propagating east but the line segments look like they're dropping southeast or due south in east TN. Probably this will get most of the Carolinas except maybe the southern part of SC with atleast some rain, and the further inland sections will probably turn into a huge mass of solid rain tonight, before ending. This is just round one of several for you over the next 6 days.

SPC

Numerous severe storms persist across the watch area. Thus far the

main threat has been large hail...with most of the activity being

single cells. However...activity has begun to merge over middle and

eastern Tennessee...with signs of outflow surging southeastward over eastern Tennessee. This may

result in an increased wind threat eventually spreading into northern Georgia

and the western Carolinas. Thus...additional counties are likely to be

added to the eastern part of the watch.

The line from Newport, TN to Andrews, NC has my interest the most. Graham county actually has a TVS on it from its cell that's currently crossing the area. Large severe thunderstorm-warning in place associated with that particular segment.

the latest run of the RUC(not great I know) has very strong VV over our region, roughly northeast GA to western SC and southern NC the next few hours and expands that out. In fact a small low develops north of Athens, I'm not sure if its just trying to do that b/c of the front and gathering some spin or its a sort of mesoscale convective vortex, very rare here. Either way, it congeals and expands a huge mass of rain as it comes our way and then into most of NC later tonight. There's a strong temp gradient right now in GA to here, with 70s in NC and upper 90s in northern Alabama.

Not having KGSP up and running really puts a cramp in watching these storms...I'm currently using Morristown which shows the cell east of Asheville shrinking...yet the thunder has really picked up here in the last 10 minutes. It may be running far enough away from the Morristown site or maybe it is getting weaker...

Also, this airmass that was in place this morning is really doing a good job eating away at the front portion of the rain shield...that should begin to moisten up for us over the next couple hours.

Really hoping we can get a good thunderstorm here accompanied with a lot of rain, really sucks having to use MRX's radar.

The line entering Southwestern NC, near Cullowhee, from Tennessee just got warned.
