DAYS 1-5 (MAY 6-10)

The surge of warm air that came in early this week remains with us for part of today, but along with a lot of cloudiness and eventual showers as a cold front approaches from the west. Two waves of low pressure ripple up along this frontal boundary, the first slowing its approach initially. Showers occur as the front nears and crosses the region, particularly this afternoon and tonight. There’s a slight chance of a few thunderstorms as well. The second low pressure wave will slow the front’s offshore departure, allowing for another round of showers early Thursday, particularly from the I-95 belt eastward, favoring southeastern MA. Later Thursday, a clearing trend begins and I expect fair, cooler weather ending that day and Friday. Friday’s weather will feature a fair amount of sun but the development of some fair-weather clouds too. This weekend, a broad trough of low pressure enters the Northeast. Timing right now suggests that a wave of low pressure will bring the chance of some wet weather to our region Saturday afternoon or night, but there is the chance that this system can slip further south and be more of a miss. Monitoring guidance trends on that. For now, I expect Sunday to be a fair and milder day.

TODAY: Most sun early, otherwise considerably cloudy. Afternoon showers and the slight chance of a thunderstorm arriving west to east. Highs 67-74 except 60-67 South Coast to MA South Shore / Cape Ann. Wind S 10-20 MPH, gusts as high as 30 MPH.
