LE WEEKEND - an update(2)

Hi all

Herewith an updated forecast for the next three days . Tomorrow is not as good as forecasted 3 days ago, but it certainly remains a day with great possibilities, BEWARE though that the NOAA maps show an indentation of stable air running well inland (to Beaufort West) to the east of us - I believe that makes tomorrow a firmly front ridge day.
