      Washington D.C. Forecast: Cloudy, cool, damp and dreary

      Tonight:Partly to Mostly Cloudy, Cool Lows: Upper 40s to Mid 50s Wind: NE 5-10 m.p.h. Wednesday:Increasing Clouds, PM Showers Highs: Low to Mid 60s Wind: NE 10-15 m.p.h. Thursday:Areas of Rain Likely Highs: Upper 50s Precipitation: 60%

      Clouds will be slowly but steadily increasing tonight and tomorrow morning in response to an area of low pressure that will slowlyand I mean slowlymove northward along the Atlantic Coastline. With high pressure anchored off of the New England Coast, this low pressure "creeper" will produce a long duration flow of chilly, moisture-laden air from the ocean right to your home. We have seen this atmospheric set-up before. And what usually happens is the heaviest rain stays along and east of the I-95 corridor and the farther west you go towards the Appalachians, the drier the air will become. We believe the steadiest rain will be from late Wednesday through Friday morning.

      After that, just periods of light rain or drizzle until the low finally wanders farther away from the coast. This is the late autumnal version of those long strings of sunny, dry and mild days we so enjoyed for the last 5 weeks or so. There is always a chance the low could move out more quickly and allow the return of sunshine by the weekend. Just like there is a chance I could win the Powerball Jackpot.
