The only thing I can predict is that it will be unpredictable. However, it will be interesting to see how quickly or slowly the forecasts change

Looks like the WaPo's left hand may not know what the right hand is already doing.

My Prediction for DC on Jan 20, 2008

1) It will be colder than August 20th

2) The sun will rise earlier and set
later on August 20th

3) Leaves will be off trees

4) The grass will not be green

5) Chance of frozen precipitation will be greater than on August 20

6) Chance of PM thunderstorms will be less than on Aug 20th

7) It will be sunny - unless it is
cloudy

8) Someone by chance will correctly
forecast the weather for Jan 20th a
week or more in advance and think they
are expert forecasters.

Using prayer and positive thinking, my wish is that both the day and evening weather for Mr. Obama's special day and for all of the visitors that will be arriving to witness and celebrate this most amazing time in history be mild with no rain. I want people and especially first time visitors to remember their experience on the Nation's front lawn with joy: joy that the weather cooperated; joy that there were enough sanitary facilities; joy that everything was a positive experience; and, joy that we as a Nation are embarking on the Road of Redemption in the eyes of the American people.

The average temp. at DCA on 8/20/08 was 75. So if some REALLY warm gulf air came up, it just might get close to that on 1/20/09...:)

@Steve - LOL. Great post!
I concur with Jamie. It will be very interesting to see how the forecasts from 18 days out change. It will also be very eye opening to see how the science of predicting weather helps improve (or not) the forecast as the day gets closer. Us GFS "huggers" are in for a ride!

There will b weather & it will last the entire day. Partly cl. 47.

Hoping for a snow event similar to the one that happened about the same time in January 87. Thunder snow, 3+ inches of snow and hour, gale force winds etc starting Sunday and continuing through the inauguration. Perfect weather for inaugurating a Bolshevik. Weather will force the inauguration inside, the balls will be cancelled and the country will begin its longest Depression ever with thousands of Americans losing their lives here in the US in terrorist attacks and this commie trying to take away our guns!

I think snow and lots of it is the order of the day.

It will be sunny and dry with temperatures in the 50's on Inaugeration day. The trend this winter seems to be the Washington area missing the snowstorms which have hit most of the rest of the country including Boston, New York, Chicago, Seattle, Portland, Cleveland, New Orleans and Las Vegas just to name a few so the outlook will be less or no snow here musch like the snowless winter of 1997-98.

Who Knows? PLEASE urge the President Elect to remember Harrison and for the sake of his wife, children, onlookers and the nation, wear a hat, topcoat, scarf, if the weather dictates and oh yes KISS that's keep it short sweetie.
