The ocean storm that gave us a couple days of snow has moved on and now it will be warm and sunny for the weekend. Surface temps prevented the snow from sticking, except for a little coating this morning here in JP. High pressure will now take control of the weather for several days, providing New England with sunny skies and milder temps. The nice weather will stick around into next week as well.
Boston, MA forecast:
Tonight: Clear and cold. Lows near 29 Downtown, 27 in JP and 22 west of 128.
Saturday: Sunny and warmer. high 52. NW wind of 10-15 MPH will keep away the sea breeze.
Saturday night: Clear, lows in the 20's to near 30.
Sunday: Sunny with a sea breeze. Highs near 50 downtown, 53 in JP and 58 inland. However, temps falling into the mid 40's in the afternoon along the coast, including Boston.
Monday: Another nice day with sunny skies and highs around 50.
Why does being just a few miles from downtown in JP make a difference in temps by as much as several degrees?
ReplyDeleteAt night all the concrete buildings and pavement Downtown help keeps the heat in. Here in JP, we are just far enough away to cool just a tad bit more at night. In towns outside the city, when skies are clear temps usually fall fast after Sunset. It is cooler in the suburbs because the heat evaporates off the grass, and that allows the cool air to come in. In all areas low temps usually occur just before sunrise. During the day, we are usually about the same but in the spring when a sea breeze develops, it can be several degrees cooler downtown then in JP. The sea breeze reaches downtown usually by noon, then it reaches JP an hour or 2 later. Rarely, the wind turns onshore at Logan, and remains a land breeze here. Inland, it will remain a land breeze, and that allows temps to continue to rise throughout the afternoon. Sometimes, it can be as much as 15-20 temp difference between downtown Boston and Concord,MA, for example. During other seasons, temps usually are about the same. High temps usually occur in the mid afternoon, if there is no sea breeze. Sorry if that was too complicated.
ReplyDeleteNo, not too complicated. That's just what I was looking for. Thanks.
