Today will feature clear skies and seasonably mild temperatures as high pressure builds in from the west. Northwesterly breezes are ongoing this morning, but will shift to the west and taper off a bit towards midday as high pressure moves overhead. Clear skies will promote strong daytime heating despite the cold air advection, and highs are likely to range from around 40 in the north to around 50 in the south. A sea breeze will try to develop this afternoon, but will be held at bay by large-scale westerly breezes. Only the immediate coastlines are likely to notice a cooldown.
As a quick side note, I will be giving a talk at the Yarmouth Historical Society this afternoon at 2 PM. I’ll be discussing Maine weather, what makes it special, and how you can help people like me predict it better. I’ll also talk a little bit about who I am and how I got to be where I am today. Stop by and say hi if you’re around!
