The approaching fronts has made today flyable but nowhere near as good as it has been.  It is unlikely that we can safely fly tomorrow, although the winds are still fine.  Today the winds have moved more to the south.  It is likely that it will come onto PN but we will go earlier, before 11am to the southerly site as I do not expect to be flying after 3pm.  There is an early ground inversion to 1600m, but once the temperature reaches around 30ºC then the thermal quality will be good but the upper level instability will lead to the quick formation of Congestus clouds and CBs.  You can see on the map the trough line running along the Sierras from around Segovia onwards.  You  can also see from the hirlam surface winds that the convergence runs many Km to our north, but the perfect direction to avoid the airspace!

We will leave around 10.30 to 10.45 if possible.
