Up here “Massachusetts had its warmest spring in the 116 years that conditions have been recorded, the National Oceanic and Atmospheric Administration says.
Connecticut, Rhode Island, Maine, New Hampshire, New Jersey, New York, Vermont, and Michigan also set records for the March-to-May period that meteorologists consider to be spring. By contrast, the same period was among the 10 coolest for Florida, Alabama, and Georgia. (Boston Globe, June 10, 2010)
Also, “much of the area from Little Rock, Ark., St. Louis, Mo., and Chicago, Ill., to Portland, Maine, New York City and Richmond, Va., temperatures have averaged 3.0 to 6.0 degrees above normal this spring.” http://www.accuweather.com/blogs/news/story/33055/100degree-heat-may-follow-reco-1.asp
In May it averaged 72 versus normal 67 and you could have planted tomatoes in April, rather than waiting till the official safe date of May 31.
This is much contrast to last year, when it think it was May that was the fourth coldest and June the second cloudiest, or vice versa, on record.
However, i was not able to work much after the middle of May in my neighbors plot, but the corn that did get planted is already knee high. thanks be to God. I also have 16 tomatoes plants on the roof, which i began inside from saved seeds, and being on the north side of a hill, with no south facing windows, the do not get that large. But some are now big and bushy with lots of flowers, though they are 3 plants in each 22”x15”x13 bin.
