That 60s Show
Steve Scolnik @ 5:00 PM
Except for Friday, every day this November has had temperatures of 60 or above. As Camden noted in the earlier comments, we had "fropa" (frontal passage) around 10:00 this morning, but the "cold" front was distinguished much more by a wind shift from south to north and a drop in dewpoint of about 10 degrees. The temperature continued to rise under broken middle and high clouds, reaching 66 by 2 pm. This will be the 12th day out of 14 with above-average temperatures so far this month. Fully 75% of the 167 days in the 5 1/2 months since June 1 have been at or above the long-term average.
November has also been very dry; the official total for the month is only 0.05". This is on a pace which could break the record of 0.29" set in 1981. Radar at mid afternoon showed some very widely scattered showers extending from eastern Frederick County, MD southwestward across eastern Loudoun County, VA to a point south of I-66. It was not clear how many of these were actually reaching the ground, but Dulles was reporting light rain at 4pm. By 4:45, a few showers were reaching the northern and western portions of the Beltway.
Tonight and Tomorrow
Tonight, overcast skies should keep low temperatures in the low to mid 50s in the city, a couple of degrees cooler in the suburbs. There is a 40% chance of scattered showers. Tomorrow will be mostly cloudy with highs around 66.
Tropical Beat
Despite the debut of the "Season of Fury" documentary on the Weather Channel last night, the hurricane season is definitely not over. For now, though, Tropical Depression 27 has remained somewhat disorganized over the eastern Caribbean. At 4pm, it still had maximum winds of 35 mph. Some slow strengthening is expected; it would not take much to reach tropical storm strength tomorrow. The forecast track has it moving steadily westward across the Caribbean, possibly reaching hurricane strength by next weekend.

Capitol Climate
The next American Meteorological Society Environmental Science Seminar on Capitol Hill is this Wednesday.- Topic: Recent Advances In Understanding and Measuring Changes in Earth's Vertical Temperature Profile
- Time: Wednesday, November 16, 2005, 11:30am - 1:30 pm (Reception Following)
- Location: Cannon House Office Building, Cannon Caucus Room, Washington, DC
What are the most recent advances in our understanding of the observed changes in Earth's vertical temperature profile? Why is it important to measure the changes in Earth's vertical temperature profile with some degree of confidence, if ground-based measurements of surface temperature changes already exist? Are observations of surface and atmospheric temperature change consistent with the latest computer model results? What do these new observational datasets and climate model results tell us about the possible causes of recent temperature changes?The next seminar is scheduled for December 14 on "Natural Disaster Preparedness".
