Golden Rule Days

By Chris E. Forest
Staff Meteorologist

A golden rule: if the winds come off the ocean, expect oceanic weather. Being in Cambridge, we sometimes forget that the ocean lies just to our east but today's weather will be a firm reminder. With that in mind, we take a look ahead to this week's weather. As a high pressure system sits to our north, the anticyclonic winds (CCW) around the system are bringing oceanic air onto the eastern parts of Massachusetts and with it, the requisite cool and damp air for today and this evening. Embedded in this flow, we find possible showers or drizzle this afternoon and continuing through Wednesday.

The main weather event, though, will approach on Wednesday night and arrive on Thursday as a low-pressure system develops over Appalachia and proceeds towards New England. Before it arrives though, temperatures should rise slightly until significant rain occurs sometime between Wednesday night and Friday depending on the development of the upper tropospheric flow.

Today: Drizzle and rain, high 67F (19C).

Tonight: Continued drizzle, low 58F (14C).

Wednesday: Partly cloudy with chance of showers, high 72F (22C), low 60F (16C).

Thursday: Warmer with developing rain, high 75F (24C), low 59F (15C).
