Coastal Storm Brings Friday Rain

Coastal Storm Brings Friday Rain

Monday’s snow storm brought seven inches of snow to Boston, which also happened to tie the record maximum snowfall for that date set in 1982. The city was lucky, since some numerical weather forecast models were predicting as much as 14 inches. An unusual event that occurred briefly with this storm was a report of thunder early Monday morning. Thunder and snow do not usually happen at the same time.

Today’s weather will be sunny as high pressure dominates the eastern part of the country. Clouds will be on the increase tomorrow as the next system moves in our direction. This system has nearly the same setup as the one from Monday, but a key difference in the forecasted position of the storm will bring us rain instead of snow. A small but powerful low pressure area will develop Thursday night over the mid-Atlantic states. The low pressure area will move northward, picking up moisture from the relatively warm ocean to our south. If the low pressure were to move more eastward out to sea, then the cold, inland air to our west could penetrate all the way to Boston and we would get snow as we did on Monday. Instead, the low pressure area will stay to the west, bringing with it warmer air from the south. This combination will result in rain on Friday. A slight change in the forecasted track of the system, however, could bring sleet or snow.
