JayB Posted January 5, 2005 Share Posted January 5, 2005 Heard something on NPR about the NWS calling for some of the coldest temps in years to settle over the PNW in the next couple of weeks. "PROGNOSTIC METEOROLOGICAL DISCUSSION FXUS06 KWBC 042023 PMDMRD PROGNOSTIC DISCUSSIONS FOR 6 TO 10 AND 8 TO 14 DAY OUTLOOKS NWS CLIMATE PREDICTION CENTER CAMP SPRINGS MD 300 PM EST TUE JAN 04 2005 6 TO 10 DAY OUTLOOK FOR JANUARY 10 - 14 2005 . . . . . . . THE NUMERICAL MODEL SIMULATIONS OF THE PREDICTED STATE OF THE MIDDLE TROPOSPHERE ACROSS THE WESTERN HEMISPHERE CONTINUE TO STRONGLY SUP- PORT A NEGATIVELY PHASED PNA-LIKE PATTERN. THIS MEANS THE CONTINU- ATION OF A VERY STRONG RIDGE OVER THE ALASKAN DOMAIN - A DEEP TROUGH OVER THE WESTERN & NORTHWESTERN U.S. - AND AN ANOMALOUSLY STRONG RIDGE OVER THE EASTERN STATES. HOWEVER...IT APPEARS AS THOUGH THE MAGNITUDE OF THE ALASKAN RIDGE IS OVERDONE BY MOST SOLUTIONS...AND THE SURFACE PROGS WILL HAVE TO BE ADJUSTED ACCORDINGLY. ALL OF THE PRINCIPAL MODEL SOLUTIONS (WITH THE EXCEPTION OF THE CANADIAN ENSEM- BLE MEAN) ARE ALSO FAVORING SPLIT FLOW OVER THE CENTRAL AND EASTERN PACIFIC...WITH A PRONOUNCED SUBTROPICAL MOISTURE FEED FROM HAWAII DIRECTED TOWARD FAR SOUTHERN CALIFORNIA AND ADJACENT NORTHERN BAJA CALIFORNIA. THIS POSSIBLE SOUTHWARD SHIFT (ALONG THE WEST COAST) OF THE PRECIPITATION ASSOCIATED WITH THE PINEAPPLE CONNECTION APPEARS MORE LIKELY DURING THE WEEK TWO FORECAST PERIOD. SURFACE TEMPERATURES ARE FORECAST TO BE WELL BELOW AVERAGE ACROSS THE NORTHWESTERN QUARTER OF THE NATION AND ACROSS THE WEST COAST STATES DUE TO THE FLOW OF ARCTIC AIR FROM WESTERN CANADA." But that's all I could find on the NWS site. Anything else about the big arctic extravaganza out there... Quote Link to comment Share on other sites More sharing options...
Ade Posted January 5, 2005 Share Posted January 5, 2005 You actually believe the forecast for the following week? I find it hard to have faith in their forecast for the following afternoon Seriously though this could be pretty good if we don't get a bunch of snow with it.

dberdinka Posted January 6, 2005 Share Posted January 6, 2005 Here's something from a NOAA special weather statement thats in more layman terms. Next week sounds chilly. 3...EARLY NEXT WEEK A SECOND FRONT WITH AN EVEN COLDER AIR MASS WILL BE POISED ALONG THE NORTHERN WASHINGTON BORDER. EXTENDED GUIDANCE INDICATES THAT THIS FRONT WILL SWEEP SOUTHWARD ACROSS ALL OF WESTERN WASHINGTON BY TUESDAY MORNING. IF THE CURRENT GUIDANCE IS CORRECT...DAYTIME TEMPERATURES WILL LIKELY PLUMMET WELL BELOW FREEZING BY TUESDAY. THE COLD AIR MASS COULD SETTLE OVER THE AREA FOR SEVERAL DAYS BRINGING FREEZING TEMPERATURES TO THE REGION. IT IS IMPORTANT TO NOTE THAT THIS EVENT IS STILL SEVERAL DAYS OUT...SO CONTINUE TO MONITOR FORECASTS AS THESE EVENTS UNFOLD. Quote Link to comment Share on other sites More sharing options...
Dru Posted January 6, 2005 Share Posted January 6, 2005 The current Environment Canada forecast apparently thinks that cold front is not going to make it as far south as Vancouver. Quote Link to comment Share on other sites More sharing options...

dberdinka Posted January 6, 2005 Share Posted January 6, 2005 i am going to climb some ice in the chuckanuts just for the hell of it. The outflow for Lost Lake is supposedly a sweet WI3/4! Quote Link to comment Share on other sites More sharing options...
Alex Posted January 6, 2005 Share Posted January 6, 2005 I am going to walk across the frozen Puget Sound to Bainbridge! Quote Link to comment Share on other sites More sharing options...
JayB Posted January 7, 2005 Author Share Posted January 7, 2005 Calling for daytime temps in the low teens in the passes on the West Side by Monday and getting even cooler by Tuesday. Quote Link to comment Share on other sites More sharing options...
