KA Winter Outlook 2007-08 For DC area
#1
Posted 23 September 2007 - 07:53 AM
Snowfall:Below average
It's not a carbon copy of last year but not much different.
Overall Temps and monthly breakdowns, for DJF, are the same: +2 to +4 for each month and thus the winter as a whole.
Snowfall:10"
Rainfall will be below normal. He believes it will be a moderate la nina season. He foresees no protracted cold spell resembling last Feb. He does see cold shots for mid or late Dec and mid Feb. He indicates that some ski resorts will go out of business. There will be a 70 degree reading in each month. He thinks there will be a minor and major freezing rain event in the DC region.
The Christmas Day forecast is for cloudy and rainy conditions, high of 50, and turning colder.
Unlike any prior winter outlook he is issuing a caveat but does not intend to use this as a fall back position. He states this is one of his more difficult outlooks because if the la nina is weak then it would be colder and even though his outlooks are analog based, and not enso, he does utilize the enso and is looking at the possibility of a weaker nina.
Analog years are 1948-49,1975-75, 1998-99,1999-2000.
I can take some question thru about 9:30 then have to leave until early afternoon

It just feels like one of those years I guess. Wait and see mode now. Hoping for a weak Nina

At least unlike last year there is no way we'll end up with high expectations and crappy results.
Sucks, but it's out of our control, and we move on.
I'll be focusing on going to places where there may be some sort of wintry weather.

Looks like you and he are at odds with the temp and snow forecasts. This is the second year in a row. I thought you used the same methods. How come you have differences?
Personally, I think KA's will be closer to the truth than yours but I profess no real skill at longer range forecasts.

I said in a post last week that we might get lucky with a 2-4 week stretch like 1/00, and he uses that year as an analog. That's our only "reasonable" hope with the mod La Nina. JI, what are your thoughts again for 08/09?
Really, no one in the MA should be surprised with this "forecast" as its the most likely scenerio for us in a mod or strong NIN. Here's hoping for a fluke. :drunk:
