The image above (courtesy tropicaltidbits) shows a warm up heading our way later this week into the weekend. The colors indicate temperature anomalies (departure from average).
High temperatures are forecast to get well into the 70s on Friday with some locations possibly making close to 80 degrees!
Unfortunately, the longer range forecast cools things back down again the following week. In addition to the warmer conditions the DC Area could also use some rain as conditions have been dryer than average.
