Weather in 1915

[Bletchley]

Those who fly in 1915 campaigns will probably have realised by now that the weather is very uniform (mostly comes out as 'variable') for most of 1915. The enclosed is historical weather information that can be used to introduce some of the missing 'dud' days when there is no flying. Note: this is not a mod, the text file cannot be plugged in to OFF to update the weather files - when you see a 'dud' day listed, use this information to skip that day by using the manual time advance (workshop setting must be set to manual/automatic). This information has been passed on to OFF Devs, so will probably be incorporated in Phase 4. Bletchley :)
