DAYS 1-5 (JUNE 2-6)
One more summery day today before it’s back to New England springtime! While yesterday’s summertime feel was with 100% sun (except the early clouds to the south), today’s will feature more a cloud/sun mix, with the clouds eventually growing to produce isolated to scattered showers and thunderstorms this afternoon, and then as a strong back door cold front sweeps across the region this evening, a more general area of showers will occur. This will signal a significant temperature drop setting up a much cooler weekend. A northeasterly air flow will keep clouds around much of the time, but enough dry air works in for breaks of sun to develop midday and afternoon Saturday, and off and on on Sunday as well. While this is occurring, a low pressure area evolving offshore will stay far enough away to keep its rainfall mainly offshore – the exception being Cape Cod where some showers likely occur on Sunday. So other than some patchy drizzle near the eastern coastal areas with the northeast wind, expect a mainly dry weekend for much of the region despite the cloudiness and cool weather. Offshore low pressure may edge close enough for bands of showers in more of the region Monday before it feels the influence of a newly formed upper low a little further west, which will keep us unsettled with a shower chance on Tuesday as well, along with continued below normal temperatures.
TODAY: Sun/cloud mix. Isolated to scattered showers/thunderstorms mid afternoon on. Highs ranging from 70-77 Islands / Cape Cod to 84-91 away from shorelines, warmest in valleys. Wind W up to 10 MPH, coastal sea breezes. Briefly gusty and stronger wind can occur near any showers and storms.
TONIGHT: Mostly cloudy. Showers likely evening to the north of I-90 and mostly overnight from I-90 belt south. Areas of drizzle and light fog overnight especially eastern coastal locations. Lows 48-55. Wind W up to 10 MPH shifting to NE and increasing to 10-20 MPH from northeast to southwest beginning late evening.
SATURDAY: Mostly cloudy to partly sunny. Passing showers north to south early morning. Chance of drizzle early morning eastern coastal locations. Highs 56-63, coolest eastern coastal areas. Wind NE 5-15 MPH, higher gusts.
SATURDAY NIGHT: Variably cloudy. Lows 45-52. Wind NE 5-15 MPH.
SUNDAY: Partly to mostly cloudy. Possible showers Cape Cod. Highs 57-64, coolest eastern coastal areas. Wind NE-N 5-15 MPH with higher gusts.
