KEY MESSAGES
KEY MESSAGE 1...Prolonged period of dry and quiet weather with moderating temperatures next week leading to increasingly mild afternoons with cool nights.
Sunshine should be more abundant today compared to yesterday as we are increasingly removed from the mid level trough, though its effects will linger. We'll continue to see diurnal clouds pop up and we'll have efficient mixing up to near 800mb. This will pull down some breezy NW gusts, generally 20-25 mph. Combined with highs in the upper 40s it will feel closer to the low to mid 40s for most, mid 30s in the slopes of the Berkshires.
There is good consensus amongst the guidance that this coming week will be dominated by a very broad surface high pressure/mid level ridging pattern with troughing over the intermountain west. Rising heights will lead to warming temperatures and keep skies mostly sunny, especially Tuesday and beyond. Dry NW flow around the high will lead to chilly low temperatures exacerbated at times by radiational cooling while highs warm well above average, into the 60s by mid to late week. Eventually a dry cold front cools the airmass down just a bit late week but no arctic intrusions on the horizon. Overall a fantastic stretch of weather for late November if you're looking to get outside and enjoy some relatively warmer days.
