Summer Trying to Settle In...
So what happened to Spring...well as is often the case here in New England we jump from mud-season to Summer. Highs today topped 80 for the first time since last October...the high at Logan was 82 set just before 2PM...dewpoints also reached the mid 60s making it very sticky. The warmth and humidity has fueled some thunderstorms development. Thus far just some general t-storms nothing severe or highly dangerous but they have included very heavy rain, frequent cloud to ground lightning and some very small hail.
A coldfront will slip through later this evening around midnight and drier and cooler air will filter in tomorrow on a NE breeze behind the front. Low clouds and fog will be present in the morning but should burn off to sunshine with highs in the 70s inland and 65-70 at the coast. A similar story should unfold on Thursday as well.
High pressure will grow offshore on Friday commencing a warm and muggy flow out of the SSW for what appears to be most if not all of the upcoming weekend. Ridging aloft will finally try and establish itself for an extended period of time this will mean highs reaching 80 or better through the holiday weekend for the interior. Along and near the coast temps will be held down some especially in SE Mass where low clouds and fog banks will plague the area through the holiday weekend. While I am calling for Summery conditions to prevail through the weekend...I am very concerned with an approaching coldfront from the west...it will fire off numerous thunderstorms over the weekend but right now it looks like it will set up just west of us. Monday is also no guarantee with the front potentially making progress and stalling over us with showers and storms. Hopefully we can be more confident tomorrow night.
