July 21 Borderline Severe Event

Friday July 21, 2006 A HP supercell formed west of St Louis MO and was moving eastward thru-out the day causing numerous reports of wind damage from St louis into IL as it approached The Evansville area the HP transitioned into a Derecho event and triggering new storms out ahead of it into southern Indiana. . Still generating wind damage reports as it moved closer to the bluegrass region.

As the storms approached louisville the system started to lose its punch a bit It was still producing areas of winds up to 60 mph but was losing streanth as it made its way into the lexington area with several breaks in the leading edge.

I went and got into position about 45 min or so before it got into the area . The line was close enough to see the darkening to the west as it got closer.

After a short time a shelf cloud like feature made its way across the sky with winds gusting to around 30 mph. about 5-10 minutes after its passage the winds abruptly died off as if someone had turned off a fan... thinking that was odd i was looking eastward at the back side of the shelf cloud now a good distance away when i hearda low roaring noise.. I knew exactly what was comming as i turned and grabbed my radio gear and map off the roof of the car i seen the wind and rain comming across the rear field of the school as i jumped into the car the wind and heavy rain hit like a truck.

The wind was making my car bounce since it was parked sideways to the wind and it had the sound of like being in a high pressure car wash.. twigs and other debris from across the feild i guess was flying by.... as i looked at the tree in front of the golf course it had some branches and lots of leaves flying off of it and instead of falling they went off on an upward direction from where they came off never really seen where they came down but had to been at least a few hundred feet from the tree. then after about 3-5 min it was over with a light rain and some moderate wind gusts .. I estimated by the look of the trees and the effect on the car it was a good 50 mph or so...
