      D.C. Area Weather Forecast: Sandy in the Future?

      Overnight: Partly Cloudy and Mild

      Lows: 53-58 | Wind: E-SE 5-10

      Thursday: Partly Cloudy, Mild but Not as Warm

      Highs: Near 75 | Wind: E-SE 5-10

      Friday: Mostly Cloudy, Cooler

      Highs: 65-72 | Wind: E 5-10

      We tied the record 84° and another mild day ahead.{ } But also ahead by late in the weekend and early next week is what could be a major coastal storm from what is now hurricane Sandy the latest track from the tropical prediction center{ }this evening

      { }

      { }

      The uncertainty of the evental track is the reason precautions are now being taken along the coast and especially from the Mid-Atlantic to New England.{ } Here is a simulation that has been quite accurate in following the unusual path of Sandy becoming a major coast storm{ }

      But, as you can see by the colors (the standard deviation) { }around the simulated center of a major storm to our east, there is still significant uncertainty.{ } Right now the impact in the DC area is mostly likely (50% chance) to be winds and some showers but no major damage.{ } There is a 20% chance of no real impact on us.{ }{ }Here is the latest plots of the various simulations we look at.{ } Still a trend to the east . . . but late October hurricanes interacting with more winter like jet stream patterns don't "obey" the rules.{ }{ }

      We will keep you posted for sure, but no big update now late Wednesday
