Rollercoaster weather this week

Strong swings in the weather conditions will occur this week. Today, the high temperature is expected to reach into the 50°Fs, but over the next two days temperatures will plummet in association with a winter storm and Thursday temperatures will only reach the mid 20°Fs.

A winter storm is likely to impact our area tomorrow afternoon through Thursday morning, but the amount and type of precipitation remains uncertain. Yesterday’s model runs indicated a track along the south coast and Cape Cod. Storms following that track this time of year usually bring rain to areas south of the Mass Pike and a mix or snow to areas north of the Pike. Here in Cambridge, precipitation will start of as rain Wednesday evening before changing to snow Thursday morning and ending by Thursday afternoon. The amount of snow we receive will depend on how early the transition occurs; it is too early to have confidence in an accumulation prediction. Hopefully it will be the last snow we see!
