Boston weather: Heavy rain later on Friday

Forecast discussion: As winds turned from the cold eastern direction to the southeast on Thursday, temperatures began to rise. We also are beginning to fall more humid in Boston today. This was due to a warm front passing through the region earlier Thursday morning. This allowed warmer air to move north, but also higher humidity. A cold front will slowly push through Southern New England tomorrow, bringing us some heavy rainfall by tomorrow evening.

Right now, the cold front is giving heavy rainfall to both North and South Carolina. We will not see the heavy rain right away. During the morning, we will have drizzle, mist, and patchy fog. His is due to the dewpoint temperatures staying relatively close to the air temperatures. As the front inches closer, the afternoon will see some isolated to scattered showers. By tomorrow night, we will see widespread showers, before becoming a moderate to heavy rain. There is the small chance for some isolated thunderstorms. At this time, we could see up to 2 inches in the heaviest rainfall.

The heavier rainfall will continue into the morning hours on Saturday, before the cold front moves offshore. The rainfall will taper off through the early afternoon, before the precipitation ends by the late afternoon. We should see some partial sunshine before sunset. We will probably see our high temperature for the day before sunset.

As we head into early next week, we will see cooler temperatures, thanks to an upper level low. Colder air streaming down from Canada will be wrapped behind the low’s center. As the low rotates over New England, we will see a series of weak low pressure systems moving like a wheel. The lows will try to create some scattered showers from Sunday into Tuesday afternoon. After the sun sets, the daytime heating will end, and we will see the precipitation come to an end. A weak area of high pressure will finally bring drier weather for Wednesday, as well as warmer temperatures. The upper level low will finally push east, allowing for warmer air to enter the Northeast U.S. For Thursday, I will go with the European model, which has a warm front moving into the region, producing some showers by midnight on early Thursday morning.
