A few thin clouds are streaming across the region this morning, but otherwise the day will start on the brighter side for most of us, especially north and east. The early-day sunshine and southerly breezes will push temps into the low to mid 60s outside of the mountains (mid/upper 50s) and Midcoast (low 50s). Clouds will be thickening as the morning goes on though, and by noon, some showers will be trying to work into the mountains. Showers will expand in coverage during the afternoon, though will generally stay north of a Portland ME – Plymouth NH line.
South of that boundary, marking the location where a backdoor cold front will emerge this afternoon, temps will climb even higher into the low 70s under partly cloudy skies. North of the front though, winds will flip around to the northeast and temps will fall into the 40s under thick clouds. Showers and thunderstorms will be developing upstream of our area over Ontario and Quebec, and their remnants will arrive with heavier rain and possibly a rumble or two after dark.
