Thats what they call a norther... I love those storms, they are fun to watch rolling in (when not flying of course).
When I moved to FL people talked about "crosswinds" and "gusts", and I was like, what winds? I took my checkride with winds 13G20 because thats about the best we got up at GTU in the early spring. I remember one time my CFI and I flew into AUS so I could get some practice with ATC about an hour before one of those storms blew in, and we had a 40kt GS (according to ATC) on 90 indicated in the tommy.
One time (about 4 years ago when I was in college), the temp (in Austin) dropped from about 75 to 40 in an hour or two (this was in early Dec). I know because I worked at radioshack at the time and we had all those indoor/outdoor thermometers on display. That was a cool storm...
