Have to be careful when looking at the precip maps on the GFS, remember that it is the average precip during a 6 hour period and not actual precip for that time period. As usual for the Deep South by the time heights fall low enough the precip is long gone but the model program thinks that the precip is still around thus it shows it as frozen precip on the map but when you click on the actual sounding forecast the atmosphere is almost bone dry.
Here's a good example, 18z GFS shows light snow across the north shore Wednesday evening as heights fall but when you click on the actual sounding forecast it shows the precip long gone.
I'd say 75% of the EURO ensembles show sizable snow events in LA over the next 2 weeks. Again we don't have a specific storm to target right now but the warning shots are there to watch for some fun thru early Feb.
The 18UTC GFS snowfall model for last Monday showed a large snowstorm for LA around the 24th and 25tth. Subsequent model runs lost it. Is that the time frame for one of these events?
