Record tying day, but Sandy increasing threat

Overnight: Partly Cloudy and Mild

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

ZZZZZ

 

 

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 

ZZZZZ
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
