After a record warm March which set the growing season into motion, the weather pattern turned sharply colder.  A strong push of cold air advanced south across the state a few days earlier.  This set the stage for frost and freezing temperatures for several days. The most significant freeze was on the morning of the 11th, when temperatures fell into the upper teens across the north and 20s over the rest of the state.  Significant damage occurred to the state's fruit and vegetable crop, as well as to local gardens and some of the trees.  The grape industry reported that damage was total on 50% of the $238,000,000 wine industry, though a limited second budding could save some of it.  Damage to the apple and other fruit trees was said to be at least 90%.  Apples are the largest fruit crop, with tens of millions of dollars at stake.
