I think we should consider adding the April 4-5 late night QLCS event to our database (it will be in my spreadsheet anyway). SBCAPE near zero in our area but MUCAPE maybe nudging up toward 500 J/kg along NC/VA border. 0-1km shear through the roof at 50-60 kts. A rare middle of the night event for our CWA, which included many wind damage reports in our VA foothills and Piedmont, as well as a couple of large hail reports, and it looks like one confirmed EF1 in Surry Co NC. However, we suspect some of the damage near Martinsville may have been tornadic but according to the County EM who surveyed it, it was ruled straight-line (thus an issue we often deal with during many of these kinds of events…weak but fast moving tornadoes embedded in an area of otherwise straight-line winds nearly impossible to differentiate, even to a trained eye). Not sure if damage surveys have been completed in other CWAs.
This was hinted at by some mesoscale models earlier in the day but as evening came, line out ahead appeared to have stabilized the airmass and mesoscale models actually were less agressive with redevelopment overnight. Us and SPC a bit behind on this as line quickly redeveloped after midnight, catching us off-guard to some extent, and with minimal staffing sitiational awareness was a challenge to keep up with. The part of the line that produced the confirmed tornado did not show a real strong circulation, but others that we issued TORs for were much more impressive, but as far as we’ve determined did not produce tornadoes (but plenty of wind damage).
We have Level II for GR2Analyst and will be archiving all AWIPS data. I assume RAH has archived the SPC mesoanalysis sector 7 for this.
