RMK: Light upslope (W-ly) wind apparent at the top of the
Downs slope, otherwise a hint of an E-ly, or this may have
simply been a change of direction during my walk. Trace of
Cu, just formed, well to the east; some of the Ci is undulatus,
presumably aligned across the upper wind which would
therefore be from about 340 deg.

1150z NNW F2 20km 1Cu037 7Ci250 22.7/12.5 1021.7
RMK: Cu hum, increased to 4 okta for a while but is now
warming out. Some dense sheaves of cirrus, COTRA also
present.

1515z NNW F2-3 25km 2Cu060 24.7/08.4 1021.0
RMK: Also 2Ci300 ... a steady decrease in amounts and
thickness of Ci in the last 3h. Surprising drop in dewpoint.

1750z NNW F2-3 25km 1Cu035 22.4/14.8 1021.3
RMK: Also 2Sc050 and a trace of Ci plus COTRA. The
contrails are barely spreading and give the appearance of
white pencil lines drawn across the pale blue sky. That
15z dewpoint looks even odder now.

09-18z: Tx 25.3 RR 0.0
