WASHINGTON DC METRO AREA FORECAST DISCUSSION
Temperatures have trended cooler for Sunday so have lowered the forecast accordingly. Additionally, northeasterly breezes may be a tad stronger than initially expected, particularly on Sunday. This will favor some higher-end Small Craft Advisory conditions for those with marine interests.
