kvegas-wx Posted October 31, 2019 Share Posted October 31, 2019 We really need to get some met commentary in here. Radar is showing a much stronger front thump developing with (maybe) a look of a few discrete cells out ahead of the main line? Somebody posted the HRRR forecasted rotation tracks earlier and this event could get out of hand really quick if that proves true. Way above my pay grade here. Would love some pro comments as folks will be headed outside as soon as 3 hours from now. (Stubborn folks that balk at moving to Friday but think they will walk their 3 year olds in a driving rain) Grrrr.... 1 Link to comment Share on other sites More sharing options...

The wind profiles are picking up across the Upstate of SC and Western NC with these storms per the Base wind velocity and composite from both the Greer and Columbia NWS radars. I would be watching those discrete cells that are crossing Greenville, Pickens, and Anderson counties as they get closer to Spartanburg and Cherokee counties. The instability levels are much higher over the Spartanburg area and Gaffney because of the sunshine from earlier today. These cells could start to further intensify as they head towards the Charlotte Metro. Link to comment Share on other sites More sharing options...
HKY_WX Posted October 31, 2019 Share Posted October 31, 2019 Def think some supercell tornadoes are possible along I40 this evening. Sunshine breaking out today has made things volatile in the Piedmont of NC. Link to comment Share on other sites More sharing options...

ryan1234 Posted October 31, 2019 Share Posted October 31, 2019 I'm surprised that there are basically no watches for the Piedmont of NC and SC. Only the extreme northern counties, thus far. Especially considering the southern portion of the line and the discrete ones in GA look a lot more eerie than the northern portion. Of course, that could change.

kvegas-wx Posted October 31, 2019 Share Posted October 31, 2019 I was just wondering the same thing....why no watches with this??? Especially on Halloween. Folks in my neighborhood are oblivious to the weather and are losing their minds about Kernersville moving to tomorrow night. You would think RAH or Blacksburg would err on the side of caution here? Edit - I stand corrected. I see the Tornado Watch issued for border counties north. I'll assume RAH is evaluating. 1 Link to comment Share on other sites More sharing options...

Dunkman Posted October 31, 2019 Share Posted October 31, 2019 Yeah the graphic they have for the watch is all wrong here's the text: The tornado watch area is approximately along and 85 statute miles east and west of a line from 20 miles west southwest of Columbia SC to 30 miles northeast of Greensboro NC. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). Link to comment Share on other sites More sharing options...

jjwxman Posted December 30, 2019 Share Posted December 30, 2019 The NAM and HRRR both support an isolated severe event on Monday 12/30. Another HSLC set up. Maybe we’ll fit in one more lightning bolt to wrap up 2019. Link to comment Share on other sites More sharing options...

nrgjeff Posted January 9, 2020 Share Posted January 9, 2020 Questions remain in Alabama due to morning rain on Saturday. Euro has consistently hammered Mississippi and the GFS has now slowed down to do the same. NAM going nearly unidirectional upstairs is a real party pooper for fans of intense severe weather though. Saturday is still the back half of the NAM (as of Thursday writing) where NAM accuracy falls off. However the accuracy issue is usually on mesoscale details. Upper wind fields is a larger scale issue. I'm afraid the GFS/Euro will trend toward the semi-unidirectional NAM. Sure it has helicity off the charts, but that is mostly speed shear. Turning is meh on the NAM. It would be a strong but sloppy line. Now the GFS and Euro (globals) both still have a classic winter Dixie outbreak. Globals start turning 700 mb wind, with 500 mb southwest or better. NAM has 700 mb barely west of south and 500 mb still SSW. They all have a mess at 200 mb, but the globals have enough turning up to 500 mb for a lot of severe wx and some tornadoes. Plus they all have robust LLJs. Instability is marginal, but that is normal in winter severe weather. Tonight or Friday morning, one could check fcst soundings for where that instability lies Saturday; low level or mid-level. If low level (just a few thousand ft AGL) it only takes a few hundred CAPE for severe. If mid-level only it's tough to light the candle. Such mesoscale detail isn't clear until about a day to 36 hours ahead. If everything comes together, one would expect that secondary warm front, originating from the Gulf Coast front, to lift north of I-20 or even US-82. Worst action would be from there south. Otherwise it's a sloppy rain-out except down on the Gulf Coast. Most of this was copied from my Tennessee Valley post. However it looks like the worst of it will be this Southeast Region, because of central/southern Mississippi and Alabama. Even there it could underachieve if the NAM is right. 2 Link to comment Share on other sites More sharing options...
