Definately! Today, Kuchera ratios would have said that while it may snow, accumulations would be quite light. Last Feb, it was very cold thru the depth of the atmosphere. 15:1 is more accurate. IMO people didn't like it because they thought it was too high.

@UtahWxMetGuy @wx_washington Kuchera worked out really well with our topography last year and I believe as well in 2019. Care to chine in Jay?

Kona lows in winter correlate well (not perfectly) with cold pattern here in the Pacific NW (if the northern branch of the jet stream cooperates!) Will be interesting to see how/if everything lines up! #wawx #orwx #bcstorm

Intense KONA storm coming for Hawaii. Subtle areas of consistent convergence often leads to the biggest flooding events out there with extreme precipitable water values. Flood watches up all islands. Blizzard warning also on the Big Island! #hiwx

Trends have not been great for Monday AM's system. Small changes in the position of the low (~75 miles) makes all the difference. Generally areas N of low will be snow, S will be rain. Trend is to bring low further N. Not good. Still plenty of time to change though! 🤞 #wawx

Morning coffee model check. ECMWF has trended north with Monday's low. So gusts to 40's around Seattle but warmer and rain. Still a chance for slushy snow around Whatcom. Low track will change again, model fun! #wawx

Granted, this is for Everett Paine Field (a typically snowier W WA lowland spot near the sound). But here are ensemble 24hr snowfall forecasts from the ECMWF, GFS, and Canadian models from the 12Z runs. #wawx #bcstorm

Strongly agree with Michael here! And if we do get some snow, amount will depend on timing and exact location (where you are). This is marginal!

#Snow EURO brings the low into a better spot for snowfall in Puget Sound, chances of at least seeing the season first snow flakes are increasing. It's gonna be tough to see accumulations on cement in the metro area. Lots of fine tuning to come, forecast confidence = LOW #wawx

If models are correct for snow ...mainly early Mon sys... use Kuchera ratios instead of 10:1. It will be quite marginal/slushy where it occurs. Here are ECMWF and GFS snowfall forecasts W WA (Kuchera). Things will continue to change and the snow may go away again! #wawx #bcstorm

Just sort of thinking out loud here, but I'm wondering if the GFS has trouble melting snow. Here is 6 hour 10:1 snowfall 18Z Mon (5 in in Seattle) with the sounding. Looks sloppy chunky rain or mix to me. #wawx #bcstorm #orwx

Without looking at too many details, I see the following (most of the snowfall is Mon-Tue timeframe). A small cold bias in the GFS -or warm bias in the other models- would explain the differences. Will be fun to validate as we go through the next few days. #wawx #bcstorm #orwx

GFS keeps showing a "deformation band" w/very marginal temps for accumulating snow, best case would be a slushy accumulation mostly grass/car surfaces. EURO is much warmer w/low making landfall in BC and giving a warmer onshore flow at the SFC, lets see what 00Z EURO brings

Saturday morning + Monday morning from the 18z GFS solution. Has the model lost its mind, or is it onto something? It is not changing its mind over the past few runs. Will be very interesting to see if other models catch on, or GFS goes down in flames! #wawx #bcstorm #orwx

Lowland snow across W WA is showing up in the GFS and UW MM5 this weekend. Other models have somewhere between a few flakes in the air to nothing. What will verify? Since cold air isn't in place, I prefer warmer cold-rain solutions at this time. #wawx #bcstorm #orwx
