We still don’t expect sticking snow TODAY here in the western Valleys…it’s just a little too warm. Take a look at our morning RPM model prediction of snowfall from 4am today to 4am Wednesday.
If anything, I think it’s a little underdone for the heavier snow showers coming in later tonight and the Wednesday morning commute. This map would imply no snow even up on the West Hills, Mt. Scott, Bald Peak etc. As mentioned in yesterday evening’s post, I think ANYONE could see a brief dusting early Wednesday morning, but a trace-3″ is sure possible near and above 1,000′ by tomorrow morning.
In the short term, one band of showers has raced well ahead of the main rain band (still offshore), and with it’s early arrival we could easily see snow mixed in with the rain as we continue to gradually warm up. 10am temps say it’s already too warm to stick; up around 37-40 at all the official observing sites. Plus, I see a milder south wind arriving right now in some of the hills like Mt. Scott and the West Hills. Good news if you DON’T want snow.
The forecast for increasing afternoon rain still looks good, but Wednesday morning should be snowy, at least in the air, for most of us.
