Sunday
The front is gone, but the strong inversion, now at 5-7000ft remains.
Surface wind - ESE 20, 5000ft E 30, 10000ft E 10, 15000ft ESE 20, 20000ft SE 30
Wave - a weak wave at 16000ft
Cloud blue
Max 27.1 Dewpoint 7 Trigger 24.5Expect 1.1 ms - 1.8 ms to 6200 ft with T-2 to 5800ft
The thermic outlook, again, is very good.
The upper layer winds are consistent (and should not swing more northerly). It should therefore be quite feasible to go quite far east using the east facing ridgelines.
Safe flying
