WASHINGTON DC METRO AREA FORECAST DISCUSSION
Looks like dry and warm conditions will prevail for the remainder of the day with few changes needed to the forecast. Have issued a Gale Watch for portions of the tidal waters Thursday and am investigating the need for a Wind Advisory in the higher elevations as unusually strong June gradient winds spread across the area.
