Today will feature (slightly) warmer temperatures and mostly sunny skies, at least for the first part of the day. By noon, clouds will be on the increase ahead of our next storm system which will be moving through Albany New York. The warm temperatures developing as a result of morning sunshine along with increased moisture flowing into the region on southerly breezes will support the development of convective showers and storms this afternoon. Expect showers and storms to first pop up in southwestern NH around noon before moving northeast. Many of these cells will produce gusty winds capable of knocking down some trees and power lines, so be aware of the potential for scattered outages this afternoon, especially over southwestern Maine and southern NH where instability, and thus storms, will be most robust.
Convective showers and storms will gradually shift towards steadier rain this evening as the low arrives in the Maine foothills. For those to the north of the low’s track, expect rain to change over to snow tonight with accumulations of 1-3″ possible especially above 2,000 feet north of route 2.
All precipitation will wrap up before sunrise tomorrow. High temps today will range from 50 in the mountains and along the peninsulas of the Midcoast to 60 in interior parts of the coastal plain.
