Prolonging Summer...
Summer may have officially ended last Friday but the last few days have been anything but Fall-like. Highs the last three days were 80, 78 and 76 for Boston and it was even warmer for towns away from the coast. The summery feel, however, will be on the retreat as a cooler marine flow sets up for a few days on the backside of high pressure. This flow will knock our temps from the 80s in the 70s tomorrow and 60s for Wednesday and Thursday. Along with cooling our temps off, the marine flow will also increase low level moisture which will lead to low clouds, fog and even some drizzle. It will take time to get the atmosphere that saturated so even though there will be some patchy fog tomorrow morning and some patches of stratocumulus during the day, the drizzle will hold off until tomorrow night or more likely Wednesday.
As we get closer to the weekend, most of our attention will be on an approaching cut-off low that has been swirling in the middle of the atmosphere over the Lakes for days and days. It will finally begin to weaken, open up and travel east but unfortunately it appears it traverses us here over the weekend. While it will be in a weakened state it still looks potent enough for lots of diurnal clouds to form and scattered afternoon showers (if not worse). This will need to be monitored closely.
