A slow start as we did not have the correct oil to top up the new winch, but once that was sorted we were launching into a 10kt easterly wind that was significantly warmer than of late, but still cold. There were some scruffy looking cumulus around, with lift underneath, soarable to cloudbase about 2500' agl. Around lunch time the clouds cleared, and the lift became allusive and then dissappeared completely with the incoming veil of high cloud ahead of tonight's front. A reasonably pleasant day out, everyone flew, its getting better.
