That should change as we go through the month. And overall +dAAMt to +AAM trend is now present across guidance. Welp with no precip being shown for Southern Cal through mid Dec there has never been a El Nino wet winter when it starts this late. Maybe this will be a first but I doubt it. For Los Angeles they are on pace for the driest Oct - Dec recorded followed by 2017 and 1990. Very un El Nino like. 2 1 Quote Link to comment Share on other sites More sharing options...

Southern third of Eastern Washington probably wont, save for the hills. May not last long, but it's something. How's your back doing? It’s not great, but not getting worse, at least. Thanks for asking. Numbness has begun to subside slightly, thanks to corticosteroid injection, but am going in for a second injection on the 12th since portions of the pain and numbness were untouched by the first one. Started PT last week, seems to be helping somewhat but honestly at this rate the recovery will take 6+ months and I don’t know if I have the patience for that. If I have one more setback, doc will recommend surgical options. Because it’s a threshold case as is. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

the_convergence_zone Posted December 5, 2023 Report Share Posted December 5, 2023 I can't possibly be disappointed by this winter because I figured I would get zero snow. Even a single flake would be an overperformance. Just hoping for no drought and decent mountain snowpack. It seems like we're checking the 'no drought' box. Mountain snow is going to be trickier but maybe we can at least get to 75% of normal in the Cascades. 3 Quote Link to comment Share on other sites More sharing options...

My guess would be if there had been more snow in the Stillaguamish watershed, there would be worse flooding. I'm not an hydrologist, but a quick literature search reveals that this is a hot topic in atmospheric river hydrology, the term for it is "Rain On Snow (ROS)" flooding. It can not be distilled down to a yes or no answer, the properties of the snowpack are important -- the "cold content" (i.e. temperature), the density, and the liquid water content. Not surprisingly, heavy rainfall on top of relatively "warm" snowpack produces the greatest runoff, up to a 50% greater streamflow:rainfall ratio than if there is no snow. Intuitively, I don't think deeper snowpack is going to make much of a difference because the rain can only accomplish so much heat transfer to warming and then melting the snowpack before it cools to 32 F. In an event like this one, there was still plenty of snow available to melt...the central Cascades had 93% of normal SWE on Monday morning. 3 Quote Link to comment Share on other sites More sharing options...
