FWIW all you folks who think we wimpy easterners are bitching about nothing, the temperatures in the last few days up and down the east coast have been 15-30 degrees below normal. For instance the average high here in N. Va. this time of year is 70 F average low is the mid 40's F. Yesterday it didn't break 40 here. the last big measurable snowstorm in April around N. Va. was back in 1990.
We already had a stretch of warm weather last week into the 80s (My backyard hit 92). EVERYTHING we have leafed out weeks ago, all trees have extremely tender and vulnerable new growth. So yeah, we're bitching because there is a danger we could lose stuff if we don't act.
