Yet statistically not too far from normal for precip. Looking forward to the first actual dry day of the month tomorrow. This wet period was perfectly timed to challenge December records since it started exactly at the beginning of the month. Global warming argues for more warmth and more extreme drought and wet patterns. This year fits that mold.

Temps continue to be very borderline. Surface temp difference between operational GFS and WRF is quite significant for this event, the GFS is way too warm for snow but the WRF soundings indicate a decent low level layer of cold and dry air before the precip arrives. I am inclined to lean towards the higher resolution WRF for details like this. http://www.atmos.washington.edu/mm5rt/data/current_gfs/images_d3/kpdx.39.0000.snd.gif 1 Quote Link to comment Share on other sites More sharing options...

Gradient Keeper Posted December 26, 2015 Report Share Posted December 26, 2015 I have somewhat encouraging and exciting news to bring you. It’s kind of like Santa’s big sack of toys, but not really…. I’m only posting the goodies. for Portland-Vancouver metro and the Gorge. AREA FORECAST DISCUSSIONNATIONAL WEATHER SERVICE PORTLAND OR317 AM PST SAT DEC 26 2015 THE NEXT SYSTEM IS POISED OFFSHORE ON THE INFRARED SATELLITE IMAGERY. WE SHOULD SEE SOME HIGHER CLOUDS SPREAD IN TODAY. THE MAIN FRONT COMES ONSHORE SUNDAY MORNING AND THROUGH THE AREA SUNDAY AFTERNOON. HOWEVER THE MODELS DO SHOW AN AREA OF PREFRONTAL SHOWERS THAT DEVELOP INLAND TONIGHT AND HAVE ADDED SOME LOW POPS FOR THAT. QPF WITH THIS FRONT IS MODEST…AND EXPECT SNOW AMOUNTS IN THE CASCADES AND THE COASTAL MOUNTAINS AND CASCADE FOOTHILLS WILL GENERALLY STAY BELOW ADVISORY THRESHOLDS. HOWEVER…WITH ANOTHER COLD NIGHT TONIGHT…THE INLAND VALLEYS WILL START OUT QUITE COLD SUNDAY MORNING…SO THERE COULD BE SOME SNOW IN THE MORNING AND EARLY AFTERNOON TO RATHER LOW ELEVATIONS ESPECIALLY NORTH OF SALEM. INCREASING EAST WINDS THROUGH THE GORGE WILL CONTRIBUTE TO THE LOWER SNOW LEVELS AS WELL… INCLUDING IN THE GORGE AND THE UPPER HOOD RIVER VALLEY. ADVISORY THRESHOLD AMOUNTS IN THE NORTH VALLEY AREAS AND IN THE GORGE ARE ONLY AN INCH…SO WILL NEED TO MONITOR HOW THAT DEVELOPS.THE UPPER TROUGH COMES ONSHORE SUNDAY NIGHT AND MONDAY WITH SOME SHOWERS CONTINUING…THOUGH NOT A LOT OF QPF. THAT MAY BE ENOUGH TO MIX UP THE CHANCE OF ANY LOW ELEVATION SNOW IN THE NORTH VALLEY AREAS BUT PROBABLY NOT IN THE GORGE. TOLLESON .LONG TERM…MONDAY NIGHT THROUGH FRIDAY…ANOTHER SYSTEM IS FORECAST TO DROP IN FROM THE NORTHWEST EITHER TUESDAY OR TUESDAY NIGHT. THE ECMWF AND GEM MODELS ARE FASTEST…THE GFS MODEL IS SLOWEST. THIS TRAJECTORY AND THE BIT OF EASTERLY PREFRONTAL WIND SUGGESTS **SNOW LEVELS WILL AGAIN BE LOW ESPECIALLY IN THE NORTH AND IN THE GORGE. THE PRECIPITATION EASES WEDNESDAY ESPECIALLY ON THE ECMWF AND GEM MODELS…PERHAPS NOT UNTIL WEDNESDAY NIGHT ON THE GFS. HAVE USED A BLEND FOR NOW FOR TIMING OF BOTH THE ONSET AND THE ENDING OF THE PRECIPITATION. AFTER THAT…THE MODELS ARE INSISTENT THAT A STRONG UPPER RIDGE WILL BUILD INTO THE AREA BY THURSDAY… RESULTING IN DRY COOL OFFSHORE FLOW THROUGH NEXT WEEKEND…THOUGH FOG IS POSSIBLE AWAY FROM THE GORGE IN THE SOUTH VALLEY AND NORTH OF KELSO. TOLLESON This to me seems very possible. It’s kind of a classic overrunning/transition event scenario. We have colder air now settling into the Columbia Basin with temps as of 4 AM in the upper teens to mid 20’s from roughly Hermiston northward. It’s even colder further north. With high pressure sliding inland the cold pool is developing. Lots of stratus/fog is an indicator of this also. PDX-DLS is now switching offshore and east winds will develop later this morning. That will pull the colder/drier air westward through the Gorge. My hunch is like usual models are trying to weaken offshore gradients too quickly late Sunday into Monday. We’ll need things to come together just right(huge surprise), but this definitely isn’t impossible especially late December where it doesn’t take a whole lot to give PDX snow/wintry weather. The 00z WRF 4km sounding was really close to a snow profile, if even briefly. 00z runs tonight will pinpoint things better. The other thing to watch for late this week towards New Years is the strong east wind. WRF suggests east wind increases today peaking Sunday morning-afternoon, then it redevelops this Tuesday and peaks Thursday night – next Saturday maybe longer. A very strong PDX-DLS gradient is shown. With the building inversion/warming 850mb temps and a 1040+mb high over the Columbia Basin this screams east wind storm, possibly damaging east of I-205. This also looks like quite a prolonged period of chilly/cold east winds. I can’t tell you how many times we’ve seen this in past Winters and that models do not handle these patterns well or play “catch up” to things as time progresses. I have high confidence this will play out too 6z GFS Ensembles - Portlandhttp://www.wetterzentrale.de/pics/MT8_Portland_Oregon_USA_ens.pngTrending a bit colder through New Years eve. Mean temp dips to -5c and note although precip looks rather meager, when it does occur 850s are -0c or colder. This suggests the east wind will pull enough cold air westward keeping the cold layer just thick enough over PDX for the potential of some kind of Wintry weather Sunday until roughly New Years Eve. Obviously a few wild cards and uncertainties such as moisture, 925mb temps in real-time, and surface flow are crucial. Seems promising to me nonetheless. You can also see the mean temp on New Years Day, Friday rising up towards +8c with a several members suggesting up to +10c. This gives more support for the coming big east winds(in my opinion) If we see 850s at +10c or > it could be crazy. Plenty of time to monitor these things. 2 Quote Link to comment Share on other sites More sharing options...

Gradient Keeper Posted December 26, 2015 Report Share Posted December 26, 2015 Wow. Yakima is down to 3 degrees now. Snowcover is awesome. This cold pool has a chance to get real strong in my estimation. Ephrata-Wenatchee-Moses Lake-Pasco-Pendleton could turn VERY cold overnight into Sunday AM. That's great for us since it will be funneling very cold east wind into PDX. Quote Link to comment Share on other sites More sharing options...
