Crisp Turns to Damp


Increasing clouds, cool. A thickening high overcast moving literally over the top of a slowly retreating high pressure area (1024 mb/30.26" at 4pm at National) has kept the string of below-average temperatures going in the Washington metro area. By 4pm, readings were generally in the low 60s with a light southerly breeze.

Tonight and Tomorrow

Increasing chance of rain. Lows tonight under cloudy skies will be close to the long-term average for a change, near 50°. The chance of rain will increase to 50% by morning. Highs tomorrow will be only around 59° with rain becoming steadier and heavier by noon. While the models are keeping the heaviest precipitation west of the mountains, the latest output this afternoon brings an area of up to 1" of rain into at least the western portion of the DC region by tomorrow afternoon.

Climate Corner

The discussion has continued into this afternoon over Andrew's Sunday Undercast, "Climate Change: Denying Denial."

Yesterday's Climate Code on The Weather Channel included more evidence that the climate change issue is NOT political, despite the attempts of some to make it so. It included an interview with the president of the Chicago Climate Exchange, which provides a market for trading greenhouse gas emissions. It also covered the environmental characteristics of the new office tower being built in New York by that noted left-wing radical anti-capitalist organization, Bank of America. If you missed the Sunday broadcast, it's scheduled to be repeated this Saturday.
