Classic SW convergence day for open distance.

From the Hirlam surface winds we can see a typical convergence setting up running for about 200km in the afternoon.  Winds are SW and on the stronger side.  It is unlikely to be any good for decent evening soaring so this is the day for sure to go big if you can.  Thermal tops altitude increases throughout the day but is low to start with so it will be easy to go down early in the day, however if you are in the air still around 3pm you are sure to do something big.  The predicted convergence does not take us quite through the airspace corridor to the north near Valladolid so be careful with the  Madrid TMA limits.  The best route for the convergence is well to the North so we won’t be crossing the Pass today but going to the flatlands to the North.

For those interested in learning about Skew T diagrams then the best site I know for tutorials is .

Obviously we will be going to La Lastra.  Briefing around 10.15 and leaving 10.30.
