Not a Moderate Risk bust!


Today started out in the Outer Banks as we wrapped up our family vacation this morning and headed back home, arriving a little after noon. Given the SPC prognostication of a Moderate Risk for our area I was a bit wary of a bust, given our previous track record. However, I couldn't pass up the chance to check out a supercell composite value of 12 (a one provides a decent probability of supercells...12 is obscene!!) in our general area so I scampered west to Culpeper where I used a known wifi location to check radar. An outflow boundary from this morning's Mesoscale Convective System (MCS) was pushing up storms in northern Virginia, but I had no desire to fight that sort of traffic so I moved south to intercept a small storm that was pushing east from Orange into some pretty juicy air. It turned out to be a good decision as I found a wallcloud exhibiting rotation and a likely funnel south of the main rainshaft while enjoying a very nice CG show. As the storm rolled eastward I paralleled it as best I could on the county roads just north of Lake Anna in southwestern Spotsylvania county, glimpsing another possible funnel through the trees (although it was probably just interesting-looking scud). I found a decent vantage point and saw some greenage along with a decaying wallcloud that could have been mistaken as a funnel. At this point convection had begun to fire all around me so I wound my way eastward to Rte 208 just north of Lake Anna, where I sat for a while to let the line push by me and allow me to (a) watch the rear flank and (b) not have to drive in the heavy rain. While I watched I saw a significant hailshaft manifested on a storm just to my southeast. I finally wandered my way home around 4:30 having put sufficient mileage on my bones for the day.

Hi Chris!
I enjoy your blog and visit often although most of the time I have no idea what you're talking about but you are "educating" me and I can say "wall cloud" in a really wise tone to the "uneducated" weather observers around my house! LOL..I hope to see you on July 5th for Frances' 80th!
love, "Ant" Ginny Hall that is..
