DAYS 1-5 (MAY 2-6)
A “cold front” pushes through today. I put it in quotes because even though it is a cold front by text book definition, it will actually warm up behind it as it is pushing out a warm airmass that was sitting above cooler marine air trapped at the ground in a lot of the region, though some areas south and west of Boston did get to experience the warmer air before the front arrived. A cool pool in the upper atmosphere will drift across the region Wednesday and will at the very least develop some diurnal cloudiness, and perhaps some showers. High pressure will move in providing a gem of a day on Thursday, though sunshine may fade later in the day as high cloudiness moves in ahead of a broad low pressure area. Though the timing of this system is still a little uncertain, it will arrive with wet weather sometime Friday. Its broad associated upper level low will park itself west of New England by Saturday, which will be another unsettled day.

DAYS 1-5 (MAY 1-5)
A warm front struggles across the region today from southwest to northeast, setting up a contrast in temperature. This will be followed by a cold front west to east tonight when a greater chance of showers and possibly a thunderstorm will occur. This exits early Tuesday, which ends up warmer due to a westerly wind. High pressure builds in with fair and cooler weather Wednesday. Low pressure approaches Thursday and brings a solid chance of wet weather by Thursday night and Friday.
TODAY: Mainly cloudy but sunny breaks possible later in the day especially Boston area west and south. Highs 48-56 immediate coast, 57-66 most other areas but may reach 67-72 interior areas west and southwest of Boston late. Wind light variable eventually becoming S.
TONIGHT: Mainly cloudy. Showers and a chance of thunderstorms mainly after 10PM from west to east. Temperatures rise in northeastern areas and only fall slightly to the southwest then remain steady 55-63 overnight. Wind S to SW 10-20 MPH shifting to W.
TUESDAY: Mainly cloudy with a few lingering showers early then partly to mostly sunny. Highs 66-75, coolest Cape Cod. Wind W 10-20 MPH.
WEDNESDAY: Partly cloudy. Lows 45-53. Highs 58-66.
THURSDAY: Increasing clouds. Rain at night. Lows 45-53. Highs 60-68.
