Severe Storms Possible Sunday; Flooding Threat Monday

Expect increasing chances of showers and thunderstorms across the DMV region starting this weekend, with the main front approaching from the Ohio Valley. Sunday and Monday are particularly noteworthy, with a marginal risk of severe weather on Sunday afternoon and evening, characterized by damaging winds and a possibility of flash flooding. Showers and storms are forecast to continue each afternoon and evening into the following week, typical of the summer pattern.

Monday has been flagged as a day to watch closely for flooding issues, with the potential for torrential downpours. This risk could be amplified if heavy rainfall repeats in the same areas or impacts urban and poorly drained locations. Highs will remain in the mid-80s on Monday due to cloud cover. Beyond Monday, the oppressive humidity will return as daytime highs approach 90 degrees from Tuesday through Saturday, with scattered storms most likely during peak heating hours.
