Emily I lived in the Catskills for 20 years and later in the Fingerlakes of NY for 4 years and we were zone 4b there. Your 7 description sounds similar to the 4b I experienced though we probably got more snow (yearly average was 8 feet).
In this zone 7 I now live in it is very warm (87 last few days and today). We're cooling off to 70 tomorrow
. Plants are running about 1 month ahead of my sister's garden in Poughkeepsie, NY. Azaleas are blooming, daffodils are finished, tulips are almost done. Iris buds are up and almost ready to bloom. Most early magnolias are finished blooming. Quince shrub finished too as did several early blooming trees I can't identify. In other words we're done with early spring and moving into mid to late spring.
