Heavy Rain With Isolated Thunderstorms Late This Afternoon Through Tonight

Radar imagery as of mid-afternoon indicated that an area of heavy rain is pushing northward across southern Connecticut and southern Rhode Island. It is expected that heavy rain will rapidly overspread the entire area from south to north starting across areas near and south of the Mass Pike by 4 pm and then reaching areas near Route 2 by 5 pm. Heavy rain is then expected to continue right into a majority of tonight. That said, the heaviest rainfall appears that it’ll occur between 7 pm and midnight or so. In addition to this, there’s expected to be enough unstable air around so that some isolated thunderstorms are likely. Any thunderstorms that do occur this evening will produce extremely heavy rainfall and localized flooding. Rain is expected to gradually come to an end between 4 am and 6 am Monday morning. Rainfall totals from late this afternoon through tonight will range between 1 and 2 inches with localized amounts of up to 3 inches possible. Reports from southern Connecticut and southern Rhode Island indicate that torrential rainfall is now occurring there leading to very poor travel conditions. This means that I want you to be aware that extremely poor travel conditions are likely once the rain begins across the area during the 5-6 pm hour due to very heavy rain. These very poor travel conditions are likely to continue through tonight due to very poor travel conditions caused by heavy rain, road flooding and low visibilities.
