Slushy Inch Posted January 17 Report Share Posted January 17 2 minutes ago, Phil said: Also ignore the “L” symbol on those WxBell graphs, it’s next to meaningless as these mid latitude lows have multiple small scale pressure minimas, and the “L” only indicates where the lowest minima is. In miller-B nor’easter that L symbol “teleports” to the coast all the time as that portion of the storm intensifies. It’s often referred to as the “transfer” to the coast, but that’s actually not what’s happening at all. Is there a way to get real-time pressure maps?

GHweatherChris Posted January 17 Report Share Posted January 17 There is no mid level low right now, satellite image shows a somewhat tightly wound low off the Oregon Coast, nowhere near where any model showed anything for this time frame, also it is not showing signs of moving north at all currently. 1 1 Quote Link to comment Share on other sites More sharing options...

BLI snowman Posted January 17 Report Share Posted January 17 25 minutes ago, North_County said: Side note, but does anyone else call a freezing rain event a "silver thaw"? Or is that just a local colloquialism? Growing up, that's what I always heard it referred to as. But I don't think I've ever heard that phrase from anyone outside of Whatcom County. Definitely used in other places as well. Pretty consistent part of the winter vernacular until a bit more recently. 3 Quote Link to comment Share on other sites More sharing options...
Popular Post CliffMassYelledAtMe Posted January 17 Popular Post Report Share Posted January 17 Drew a diagram for my 11 year old of how we get snow, sleet, freezing rain, or rain. He looked at my drawing and without prompting said, "That looks like a really ugly nose." Yes, my son. That warm air layer is a really ugly warm nose. Hadn't even taught him what it was called yet.

Phil Posted January 17 Report Share Posted January 17 4 minutes ago, Phishy Wx said: yep, I don't think it becomes vertically stacked until it gets east of the cascades Yeah and if/when it does get vertically stacked that usually denotes occlusion. Mid-latitude cyclones aren’t like hurricanes, where vertical alignment is prerequisite for rapid strengthening. If anything it’s the opposite. Those WxBell “L” symbols are useful for tracking mature(ing) tropical systems. Meaningless for middle latitude cyclones, though. 3 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...

Phil Posted January 17 Report Share Posted January 17 5 minutes ago, TT-SEA said: Ahhhh... so the ECMWF is not totally out to lunch. Nope. At least not at that level. But precip type/etc might have more to due with boundary layer thermodynamics, where guidance is more likely to fuck up at short lead times given difficulties w/rt resolution/terrain and the different ways that physics are parameterized (some work better than others depending on the situation). 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...
