Discussion
Bands of showers and thunderstorms are going to rotate around low pressure today which is now situated near the southern tip of the Delmarva Peninsula and some of the rain will become heavy at times. The best chance for excessive rainfall amounts from Tropical Storm Fay will extend from the Delmarva Peninsula to eastern PA, New Jersey and southern New York. Given the recent heavy rainfall and the well-saturated grounds in much of the Mid-Atlantic region, flash flooding will become an increasing concern as several inches of rain can fall in some spots and there are already reports of flooding in some of the Delaware beaches (e.g., Bethany Beach). In addition to the rain, winds will become quite gusty along coastal sections and strong rip currents are likely to form in the western Atlantic. By later tonight, the low pressure system is likely to push northward into New York State bringing significant rainfall to portions of the interior Northeast US. The weekend will remain somewhat unsettled around here with the chance of scattered showers and thunderstorms and an upper-level trough will likely result in an additional rain threat on Monday and Tuesday. Later next week, it could turn pretty hot later across the Great Lakes, Northeast US and Mid-Atlantic region.
