Severe Severe Weather Threat for 6/20/19

[Brick Tamland]

Covers all of SC and some of NC, too. Weird border for NC. Wonder if we'll get another watch here.

Well, that answers my question.

 

[Webberweather53]

Absolutely absurd amounts of mixed-layer CAPE in the lowlands of SC atm, 3000 j/kg is extremely impressive and will definitely be able to maintain, if not, significantly intensify any storms that move into eastern SC later this evening.





This is also a pretty classic lee trough signature in the wake of the Apps, makes sense why storms fired where they did just west of the Triad & down towards Hickory where vorticity stretching provided an extra source for ascent.

 

[Brick Tamland]

Another watch for GA and AL.

So far the 3km NAM seems to be handling the storm evolution better than the HRRR runs this morning were. I expect the storms in Western NC to quickly grow into an organized complex with some bowing segments and widespread wind damage likely.

Yeah the NAM tends to perform much better in cases where the storm mode is linear, the HRRR has been inconsistent and spurious by comparison for today.

Once this thing kicks out east it should haul ass as well....been a while since we have had a red meat squall line firing in such a hot unstable air mass, then racing east during mid afternoon......should be quite a few blue dots on the SPC storm report page when its all said and done.

Yeah hrrr basically whiffed on the convection in the NW piedmont

Storm in Harnett County (SD's area) just got a nice red cell blow up right over Chalybeate Springs.

Yeah it did poorly with that. Once this line hits the RDU area I expect it will really blow up and start to bow out some. Going to be a rough one Raleigh and points east I'm afraid.

Several trees reported down in the Winston Salem area.

Interesting radar looks like it was close

Southern part of that line in NC is unimpressive. Looks like plenty of CAPE to work with, but it doesn't yet look to be expanding southward very much.

Probably the activity that will affect Charlotte, there is a leftover boundary to our north aswell, lets see what this cell can do and if it can release a outflow for other storms to develop on

Massive instability and good shear and the lower half of that line can't even form up. Lol

Looks like we get left out again. Seems to be the story of this summer
