Forecast discussion: Rhode Island received some heavy rainfall in the central and southern parts of the state on Labor Day. Roads were flooded, an entire first floor of an apartment complex in Cranston was evacuated due to excess water, and T.F. Green Airport received a quarter inch below three inches of rain this morning. Unfortunately, we will have to go through one more day of wet weather before we see a long dry period.
The rainfall is due to a warm front that moved into Northern New England this afternoon. With all of the heavy moisture in the air, any sunshine we did receive helped create showers, pockets of heavy rain, and thunderstorms. This will continue into Tuesday. In fact, a Flash Flood Watch is in effect until 11 p.m. tonight. A Flood Warning is in effect for the Pawtuxet River until Tuesday morning. The river went above flood stage this evening, but should go below flood levels tomorrow morning. Of course, this will happen if it does not rain any further tonight, or the area does not receive any heavy periods of rainfall.
The cold front associated with the low over Canada will pass through New England by late tomorrow afternoon, and all the rainfall will finally move offshore by Tuesday night. A strong high pressure system moving over the Great Lakes will see sunny skies on Wednesday and part of Thursday.
On Thursday afternoon, a reinforcing cold front will pass through New England. The front may create a late afternoon shower; otherwise, we will see limited sunshine by the afternoon. Cooler air will move into the region for Thursday night into Friday evening. Daytime highs will only reach the lower 70’s on Friday, before slowly increasing back into the middle 70’s for Saturday.
By Sunday, a cold front coming down from Northern New England may produce some showers by the evening. High pressure behind the front will bring mostly sunny skies for next Monday, with temperatures in the lower to middle 70’s during the daytime.
