WASHINGTON DC METRO AREA FORECAST DISCUSSION
This morning`s severe weather threat with a decaying thunderstorm complex has likely diminished and the Severe Thunderstorm Watch has been cancelled. How the remainder of the day unfolds remains uncertain, but the greatest risk for a second round of strong to severe thunderstorms may mostly be across the southern parts of the forecast area. With debris clouds around a good portion of the day, did lower high temperatures a few degrees based on the latest guidance.
