Warming Up for the Weekend...
The atmosphere will be undergoing a transformation and will be warming up quite a bit over the next few days. While temperatures aloft will be similar to Summer levels it is always tough this time of year to get that warmth to translate to the surface. We will be dealing with seabreezes and cloud cover and most critical of all...wind direction.
On Tuesday, when we look back at this stretch, I think we'll say that Saturday was the best of all of them...then Monday and then Sunday. The sun will be brightest tomorrow until late in the day when some high clouds work in but temps will climb to either side of 60 and winds will be light and variable except near the water edge where a weak seabreeze will once again form. Sunday will be tainted by increasing clouds thanks to warm air advection and there will be more of a pressure gradient creating a muggy breeze out of the south. The warmfront will be active as it passes Sunday night...showers and maybe elevated thunderstorms are likely. The front will be through by Monday morning and we will be in the warm sector then the question is where do the 80s show up!?!?! I still see 80 or better west of I95. I still see 50s, 60s and 70s over SE Mass. The question for me is Boston and the North Shore. While climo argues against the warmer solution the GFS still would pump record warmth to Boston with more of a SW wind direction. But the NAM, which of course has the better low level resolution, has the wind direction more southerly...and it's hard to go against that. Still, I'm hopeful that the record I called for a couple of days ago materializes...I'd put my odds at about 30%.
Have a good weekend...and enjoy!
