We're sitting at 4F right now with the sun starting to come up. The forecasts had us at somewhere between -2 and 0F... So you may get lucky yet. Although on the other hand there some locations about 10 miles from me reporting anywhere from -6 to -10.
Currently we are at 8 continuous days below freezing and it looks like we have at least another week before seeing 32F again. As far as the temperatures and duration of the cold goes, this winter seems to be worse than last year here in New England (but up here last winter wasn't abnormally harsh... we had one day between 0 and 1F at my house).
At least most of my plants are buried under multiple feet of snow. The only thing not completely buried is my M. grandiflora.
