Forecast discussion: High pressure ridging brought some sunshine to Boston, but by the middle of Monday morning, the shift to easterly winds from a low pressure system in the Atlantic brought clouds back over the region. A second low pressure system will bring some heavy rainfall for Wednesday and Thursday.
The low centered over western Iowa at the moment brought devastating weather over the last few days. A total of 20 people are dead and many people are still missing as tornadoes spawned through Arkansas, Oklahoma, and Iowa over the last two days. Currently, severe thunderstorms passing through Mississippi and some have spawned a few tornadoes. You can read more about it by clicking here.
For Southern New England, we will not have the severe weather they are seeing. However, by Tuesday night, the cold front will bring some heavy rain by Wednesday. The heavy rainfall will continue into Wednesday night into Thursday morning, as a new low pressure system rides up the cold front into the Northeast U.S. The computer models are predicting an inch and a half to as much as three inches of rain by early Friday morning. The heavier amounts are due to isolated thunderstorms. There is the chance of some street flooding, due to poor drainage. But, as the warm front pushes through early Friday morning, temperatures will actually reach seasonable conditions.
We are expecting dry weather for most of the weekend, as the front moves offshore, and weak high pressure ridging moves over Southern New England. There is the chance of some spot showers, due to the daytime heating. However, the main center that created all this weather will finally push through the Northeast on Sunday. We will see the risk of some scattered showers by the late afternoon, but should end before midnight. We will see mostly sunny skies by next Monday.
