DC: Delightfully Comfortable


Sunny, warm. Southerly breezes have brought temperatures a few degrees warmer this afternoon, but humidities are still comfortable as dewpoints remain in the low 50s. Culpeper and Fredericksburg were the warm spots in the region with 81° at 4pm. Except for a few isolated popup showers near the southern portion of the Virginia/West Virginia border, radar is clear in all directions.

Continued seasonably warm and dry conditions are on tap for the next couple of days.

Tonight and Tomorrow

Mostly clear, seasonable. Lows tonight under a few scattered clouds will be from the upper 50s downtown to the low 50s in the 'burbs. Tomorrow will be a lot like today with highs in the upper 70s to near 80°.

Tropical Topics

The National Hurricane Center and Climate Prediction Center today issued the official outlook for this year's hurricane season. The forecast calls for a 75% chance of above-normal activity, including 13-17 named storms, 7-10 hurricanes, and 3-5 major hurricanes (category 3 or higher). Among the factors expected to contribute to the higher activity are: warmer sea surface temperatures, reduced wind shear, and lower surface pressure over the tropical Atlantic, higher upper atmosphere pressure from the central Atlantic eastward to Africa, and a favorable African easterly jet.
