Forecast discussion: After a raw day in Providence, Southern New England will be seeing some heavy rainfall over the next 24 to 36 hours. This is due to a very strong low pressure system centered over eastern Iowa. The cold front has brought several tornadoes through the Southeast U.S. From 4 p.m. Monday until 3 a.m. Tuesday EDT, The National Weather Service’s Storm Prediction Center, there were 80 reports of tornadoes. To date, at least 34 people have been killed. For the latest information, click here.
For us, we will not be seeing the ferocious weather the rest of the nation has been receiving. We will not see the first raindrop until Wednesday morning, as the precipitation shield moves into the region. The rainfall will be increasing, as the cold front inches closer. We will see the heaviest rainfall Wednesday night into Thursday morning. We could see up to an inch of rain before dawn. Because of the predicted rainfall, a Flood Watch is now in effect for all of Rhode Island from 6 p.m. Wednesday night until 6 p.m. Thursday night.
However, despite the rain, we will see a stark increase in our temperatures by Thursday. The warm front associated with the low will pass through the area, allowing temperatures to spike into the upper 60’s. The cold front will pass through by Thursday night, and the front will move offshore. High pressure ridging will allow for some sunshine on Friday.
As we move into the weekend, the low that created the severe weather will slowly move over the U.S.-Canada border near New York. The low will receive some upper level energy Saturday morning, giving the low the chance to create some isolated showers by Saturday evening. The upper level low will move out to sea, taking the surface low with it. We will have scattered showers until Sunday morning, with drier weather for the rest of the day. A strong high pressure system will give us mostly sunny skies to start early next week.
