I couldn't resist posting this...
0610 PM TSTM WND GST 4 WNW FOXHOME 46.30N 96.39W
06/18/2009 E60.00 MPH WILKIN MN TRAINED SPOTTER
GUSTNADO OBSERVED IN THUNDERSTORM OUTFLOW WELL AHEAD OF
AN APPROACHING SHELF CLOUD.
I was going back through the LSR's at the Grand Forks National Weather Service from our chase on the 18th and found this piece of gold.
For a "Trained" Spotter, he/she clearly has no idea what they're talking about. Gustnadoes develop within a thunderstorm's outflow, yes, but also at the outflow/inflow interface. This means they develop within the shelf cloud, most often at the very leading edge. NOT well ahead of one!
Makes me wonder who was doing the training!
