This is to account for additional flash flooding concerns as clusters of storms are likely to grow more upscale may bring locally heavy rainfall over saturated soils. For Sunday and Sunday night, multiple rounds of storms are likely over West Virginia and parts of the Mid-Atlantic. The potential for locally heavy rainfall will be enhanced by energy along and ahead of a trough moving into the area. Accordingly, a Moderate Risk Excessive Rainfall Outlook is in the forecast for parts of West Virginia on Sunday, with a broader Slight Risk extending from the Ohio Valley into the Mid-Atlantic. Monday should be the start of a relatively drier pattern as the main trough axis exits off the east coast and drags a surface cold front through the Midwest and Ohio Valley.

Thunderstorms are likely to grow upscale overnight as the low level jet increases at the surface while a mid-level disturbance enters the area and provides an additional source of lift. Conditions will be favorable for training/repeating thunderstorms and will increase the flash flood potential across Illinois and especially Indiana, where the ground is saturated from rounds of heavy rainfall this week.

Overnight, a new cluster of thunderstorms is forecast to form upstream over Iowa and Illinois, eventually tracking east across the already saturated soils of the Ohio Valley. Widespread additional rainfall totals of 1 to 3 inches are expected, with localized training bands dumping up to 4 to 6 inches. Because ground conditions across the Ohio Valley are thoroughly soaked, any renewed heavy rain will immediately create rapid runoff, maintaining a threat for flash flooding through Wednesday. The next Storm Summary will be issued by the Weather Prediction Center at 1100 AM EDT. Please refer to your local National Weather Service office for additional information on this event. Eovino $$
