Meanwhile, the wettest locations were in portions of Maryland and eastern West Virginia, where abnormally dry conditions improved. April 1-15 precipitation at the major climate sites ranged from 32% of normal in Concord, NH, to 136% of normal in Rochester, NY. Overall, 31 of the 35 sites were drier than normal with seven of them having one of their 20 driest starts to April. On the other hand, Islip, NY, had its 14th wettest first half of April.
