The perfect storm?

Well - I've been waiting for it.  The cold Spring and hot dry Summer have combined to produce a bad harvest and we can look forward to higher food prices in the shops.  'Twas ever thus. At this time of year, farmers always come up with sob stories about the weather being too hot, too cold, too wet, too windy or too something else, but the punch line always is that there will be shortages of something or other and prices will rise.  Couldn't go wrong this year, could they?
