Mountain wave

I don't understand. You generally don't get mountain wave and virga at the
same time. One requires stable air and the other generally occurs in
unstable air.

Hmm. What time today were you overflying the peak. My in-laws are in
town and we took them up there around 1400 this afternoon. That was
about the time the snow and freezing rain hit with a lot of high
winds.

Just as a side note, I was out flying around 1100 this morning at COS
and even tho it was calm on the ground, we got up 1000' agl and with
all the virga around, it got real bumpy even at that low an altitude

Hit a mountain wave today near Pikes Peak at FL190 in my TR-182. First I
couldn't maintain FL190 (I only have 300-400 fpm climb at that altitude
anyway) as my indicated airspeed descended to 80 K. Called ATC, got a
block
altitude, FL 180 - 200. About a minute later I needed the upside. Shot to
over 2000 fpm climb (VSI was pegged) and with the nose pointed way down
leveled off at FL 195 and ground speed of 190 knots. Fun stuff.

He saw the virga at 11:00 am. The waves were evident at 2:00 pm. Evidently
the winds hit the front range in the afternoon.
