Light NE and moderate SW aloft with instability

An upper level cold front moved through overnight and has bought marked instability aloft which is going to cause us a few problems for decent XC paragliding.  This morning we have extended Cirrus which is cutting out the heating of the Valley and hillside, giving us a gentle SE catabatic at Peña Negra.

Trigger temperature for Cu development is around 21ºC and the instability will lead to a quick build up of Congestus and likely storms.  A quick dash to Barco may be possible, but we must evaluate the rate of growth of the clouds as otherwise even such a modest XC may become somewhat terrifying!
