A high pressure system is in control for the first half of the week, bringing beautiful weather conditions to the Boston area. Similar to yesterday, today and tomorrow should be sunny with unseasonably warm temperatures. Normal high temperatures for this time of year are around 55°F, but we may experience temperatures over 10°F higher than that. Enjoy the nice weather while at lasts, because a coastal low will approach the region on Thursday. With plenty of moisture associated with that system, there is a potential for heavy rain Thursday afternoon and evening. The low will exit Friday morning, with clouds dissipating as a high pressure moves in from the southwest. The temperatures on Friday will be more seasonal, as northwest winds behind the exiting low advect colder air into the region.
