Forecast discussion: We received mostly cloudy skies through the morning and early afternoon in Boston on Sunday, keeping our temperatures in the upper 40’s to lower 50’s. However, increasing sunshine late in the day and a warm front passing north of Southern New England helped raise temperatures into the upper 50’s, with 58 degrees reported at Logan Airport. Also, this occurred within one hour of sunset.
With the help of the warm front, temperatures will stay quite mild. Also, our dewpoint temperatures will be increasing, as the atmosphere will be able to hold more moisture. This will create some patchy drizzle, along with patchy fog. The best chance of this occurring will be along the southern coastline. Patchy fog may become dense, and create zero visibility. So, please be careful if you have to drive in those conditions.
We will see limited sunshine and breezy conditions on Monday, as a strong cold front inches closer to the east coast. We will see a high in the lower 70’s, but then temperatures will fall about 20 degrees after the front passes. Along the front will be some very heavy rainfall. Due to the speed of the front, we could see up to an inch and a half of rainfall by early Wednesday morning. High pressure will build behind the front and give us mostly sunny skies into Friday. But, it will take a while for high temperatures to reach seasonable conditions.
As we look ahead to next weekend, a cold front in the Ohio River Valley Friday afternoon will bring showers ahead of it. We will see some showers by late Saturday morning. The shower activity will be steady through the middle of next Sunday morning. We may see some limited sunshine by the afternoon. High temperatures will reach the upper 50’s to near 60 degrees.
