Doug Hill discussing NAO phases... snowfall and temps slightly below normal... but still chance of a nor'easter

Immediate DC region was in 10 to 18 swath... but Hill mentioned that higher total was more for western portion of swath towards BR. Swaths of forecasted snow for the winter were tiered NE to SW... still no matter where you are in area still believes slightly below normal snow for all.

Its on WJLA's weather website now fyi

How can you forecast anything other than slightly above or slightly below normal? No strong signals to be found anywhere.

I have a hunch that we get a good pasting with a coastal. You can't just say this fall is a fluke and dismiss it. This is probably the only thing that can make forecasts bust low too. One widespread 8-12" and it changes everything. Guidance is already pointing towards another amplified pattern before mid month. Still too early for snow in these parts but I really like what keeps reappearing. Anything but a dominant flat pac zonal please.

No matter what - whether for seasonal forecasts or individual storm calls - the locals always do the NW-SE thing. Happens where I grew up near Philly, too.

I understand it to a large degree, and I suppose it's the safe call, but it always seems like, no matter what, local weather people expect there to be more snow north and west every single freaking time.

BTW...I'm not minding the -NAO looks that ORH and Coastal were talking about. IMO, the biggest thing we can hope for in that situation is that we get a STJ disturbance or two with blocking and some cold. I see this being a northern stream-dominated winter once again, so we need to take advantage of those times when the STJ plays ball.

Does anyone really care what the former PG cop with no Met degree thinks? I'm sure any skill brought to that forecast came from Ryan.

If you buy into the atmosphere has a memory thing then any coastal that gives us snow might come early in the season. I can't see this pattern lasting all winter. My WAG is a decent early Dec snow during a volatile period of pattern changing until a cold/dry pattern sets up for Jan/Feb. when that happens we will get the occasional 2-4" event to get near climo.

I dont really buy into the memory thing irt to storms and their tracks. That's always a function of the long wave pattern. But there is a pattern there. The only way we get coastals and miller A's us when we have an amplified pattern and it usually requires blocking. We are seeing a lot of that this fall. Good stuff.

HM and Coastal are digging the Aleutian ridge this year and its potential down stream effects. Last year we had an ak vortex from hell. Damn thing was parked for what seemed like forever. If the ridging parks itself it will at least provide opportunity. Can't ask for more. If it parks in December then the odds of a cool month just went up.

Yes they would, the Aleutian Ridge does help us indeed. Sent you a PM.

I'm going to ask santa to update my weathergeek equipement this year. Right now I use a simple wired thermo with LCD. My gauge is old and glass. It's accurate but honestly I've stopped using it.

I'm thinking about getting a wireless temp/gauge setup. Signal range is no issue. I have a great spot just outside my house so it would be less than 75'. I'm leaning towards this one:

http://www.amazon.co...less rain gauge

Any other recommendations? I'm very value oriented with everything I buy. Bang for the buck and I don't need the latest and greatest.

I have been thinking about an inexpensive weather station for the house. Anybody heard of or have this one?

MODEL DIAGNOSTIC DISCUSSION

NWS HYDROMETEOROLOGICAL PREDICTION CENTER COLLEGE PARK MD

1208 PM EST THU NOV 15 2012

VALID NOV 15/1200 UTC THRU NOV 19/0000 UTC

ENERGY CLOSING OFF IN THE SOUTHEAST

===================================

PREFERENCE: 12Z NAM/00Z ECMWF COMPROMISE WITH AVERAGE CONFIDENCE

THE APEX OF A NORTHERN STREAM RIDGE (WITH 500 HPA POSITIVE

ANOMALIES APPROACHING 200 METERS ABOVE NORMAL FOR MID-NOVEMBER)

MOVES THROUGH EASTERN CANADA IS IN THE LOW 50S LATITUDE FROM

SUNDAY ONWARD...WHICH FAVORS A SLOW-MOVING CLOSED VORTEX TO ITS

SOUTH IN THE LOW 30S LATITUDE. THE GUIDANCE INDICATES SUCH A

FEATURE NEAR THE CAROLINAS, THOUGH OF THE CURRENT GUIDANCE, ONLY

THE 00Z ECMWF AND 12Z NAM SHOW THE SYSTEM CLOSED AT THE 500 HPA

LEVEL, AND ONLY THE 00Z CANADIAN APPEARS CLOSED AT THE 700 HPA

LEVEL. A STRONGER/SLOWER SOLUTION IS ADVISABLE HERE PER

TELECONNECTIONS WITH THE NORTHERN STREAM RIDGE AS WELL AS THE 00Z

CANADIAN/ECMWF ENSEMBLE MEAN SOLUTIONS. NONE OF THE CURRENT

GUIDANCE APPEARS DEEP ENOUGH ALOFT WHICH LOWERS CONFIDENCE IN ANY

MODEL CHOICE WITH THIS SYSTEM. IF ANY PRIOR MODEL RUN LOOKS

REASONABLE, A LAGGED-AVERAGE COMPROMISE OF THE ECMWF RUNS FROM

12/12Z-14/00Z APPEARS BEST. SINCE MOST OF THOSE RUNS ARE NOT

AVAILABLE FOR OPERATIONAL USE DUE TO THEIR AGE, A COMPROMISE OF

THE 12Z NAM/00Z ECMWF LOOKS BEST FOR THE TIME BEING...WITH

CONFIDENCE ONLY AVERAGE IN THIS CHOICE AS IT APPEARS TOO WEAK.

THIS SYSTEM HAS BEEN SUBMITTED AS A CANDIDATE FOR SHORT-RANGE

ATLANTIC/GULF COAST WINTER STORM RECONNAISSANCE.

The Ambient Weather WS-1090 seems to be pretty reliable and it does a good job with wind speeds. The temperature sensor tends to be flaky sometimes, especially during hot weather and light winds (Most if not all stations under $600 will have this problem). If you mount the sensor in the shade though you should be OK. Like all precipitation sensors under $1000, the rain gauge will not work in sleet, freezing rain or snow. You can run the data from the station to your computer and log and store it and even upload it to weather underground using Cumulus. Overall it's a very good station for the money.

I bought the Ambient Weather one 2 years ago for Christmas. We only had it mounted for 3 months and the anemometer crapped out and broke. Maybe it was just a faulty one. I dunno. I'm going for a Davis Vantage Vue this year.

I only want/need outdoor temp and rain gauge. I'm not worried about having to measure snow liquid. I'll just use local coop to fill in my journal when (or should I say IF) it snows. lol

I'm having a hard time finding a good temp/gauge combo. I do want it to be wireless though. I'm older and lazy. I don't like seeing the thermo inaccuracy complaints on many models. Not sure how to get around it. I can't tell if the thermo is a separate instrument that can be mounted some distance away or not. If they're all integrated into the rain gauge then there is no way to mount in shade. hmmmm. I thought this would be easier...
