Although not quite as warm as yesterday, once again much of New England approaches 90 degrees this afternoon.
The exception is in northern and eastern New England where a little bit of cooler air keeps coastal Maine and coastal Massachusetts in the 70s, with a light breeze in from the ocean. There's a weak front and enough instability to pop up a few scattered showers and a thunderstorm late in the day and early this evening.
Skies will partially clear in southern New England overnight, but the threat for showers and thunderstorms increases for Northern New England overnight tonight.
Mild and somewhat muggy overnight with a low temperature in the 50s to low 60s.
Any clouds burn off to a mixture of sun and clouds tomorrow, once again the threat for afternoon showers and thunderstorms, this time a little bit more widespread.
Warm to hot and humid with a high temperature near 90°, cooler at south facing shorelines.
Wind generally from the west and southwest 10 to 20 mph.
A frontal boundary nearby is the reason we have to keep the threat for a shower and the thunderstorm in each afternoon and evening through our Memorial Day Weekend.
It looks like the front may slip a little bit further south on Sunday, so Sunday could end up cooler at the shore with a lot of clouds and patchy fog.
If you're looking for the best beach day, probably Saturday, and again later on Monday are most favorable at this time.
As for the Lakes and Mountains of New England, there is a high probability of Thunderstorms with heavy rain, small hail, and gusty winds each afternoon and evening.
Temperatures are rather warm 60s 1000-2000', 70s and 80s at lower elevations.
