The Sun Marches On


Sunny, mild. Helped by a maximum sun elevation of 50°, temperatures rose into the 60s this afternoon in the Washington metro area, despite a northerly wind gusting over 20 mph at times. National was 63° by mid afternoon, and Dulles was 60°, while some upper 60s were reported in the southern fringe of the region. A glancing blow from a Canadian Arctic air mass will give a brief reminder of winter tomorrow before temperatures rebound to more springlike levels.

Tonight and Tomorrow

Mostly clear, cold. Under mainly clear skies, temperatures will drop tonight to the low and mid 30s in town and the mid 20s in 'burbalonia. Tomorrow will be mostly sunny in the morning with increasing clouds in the afternoon and highs only 46-49°.

Political Science

Today was Climate Crisis Action Day here in the Nation's Capital. The event to "call on Congress to pass the Arctic Wilderness Act and legislation to stop the threat of global warming" was sponsored by a number of environmental groups.

Yesterday's House Oversight and Government Reform Committee climate report hearings were covered in the CQ, LATi, NYTi, and even as far away as Australia and New Zealand, but here in Spin City, the WaPo apparently carried only the AP report online.
