Enjoying the Sunshine Fantastic
High pressure is firmly in place across New England today providing abundant sunshine. Light NW winds will shift to the WSW as the high slides off the coast. Today will become very warm with highs climbing into the upper 80's to near 90 in many locations. Cooler on the Cape & islands around 80-85. Area of low pressure up near the Canadian maritimes will help to enable a sea breeze to develop mainly north of Boston by the afternoon...especially NH & ME. Slightly unstable air across East MA and RI with cooler air aloft will contribute to some cumulus development in the afternoon.
Dewpoints will slowly rise through the day and evening. Becoming more humid overnight. After a mild start near 70 Sunday, temps will rapidly warm into the 80's by 10 AM Sunday and then climb to near 90-95. Luckily, breezy SW winds will be in place to stir up the atmosphere...but certainly a hot humid day can be expected. A great weekend for the pool or beach with near 100% of the sun all weekend.
The heat remains into Monday in the Lwr 90's with oppressive humidity in the Lwr 70's. A very uncomfortable day with hazy,hot, humid conditions. A cold front will be sliding through late in the day which may trigger a few scattered storms. Right now it appears the heaviest rain and strongest storms will push through Monday night...with the activity ending after midnight with the front pushing off the coast. Some storms may become severe with heavy downpours.
Weak high pressure arrives for Tuesday with drier air, low humidity and increasing sunshine. Temps will remain warm in the lwr-mid 80's. High pressure will be pushing off the coast wrapping in warmer SW winds again for Wednesday as temps will rebound right back up into the upper 80's near 90.
A big heat ridge currently centered over the nations' plains will be shifting east for the end of the week. This will come with the hottest air of the summer for the east coast. Temps will be climbing to 90-95 degrees or warmer by Thursday or Friday with increasing levels of humidity. Areas of the Mid-Atlantic will see the most intense heat climbing to near 100 degrees by weeks end.
We will have to watch for the potential of a backdoor front sometime around Friday which if it pushes through could make it a bit cooler and less humid for next weekend....But if the flow remains flat enough...the front will remain across the Canadian border and we will be in the middle of a prolonged heat wave which could last until Sunday with temps in the mid 90's. Quite a bit different. A little more time will be needed on the certainty of the extended temperatures.
