National Weather Service in Gray, Maine, which covers NH and most of Maine, says the first half of meteorological winter (Dec., Jan., Feb.) has been the wettest on record for both the Concord and Portland stations. That includes rain – so, so much rain – and melted snow. Not a lot of melted snow, alas.
Here are the charts, showing precipitation totals through Jan. 15 for each year back to 1870.
