The Fun Begins! 2pm Update

This is getting real interesting this afternoon.  Several things going on.

First, if you are not a weather geek, be aware that there will probably be some icy spots for the evening commute.  I doubt we’ll get a raging icy mess, but definitely cold enough in about 1/2 of the metro area to see light snow or glaze ice in spots after sunset (5pm).  Things are moving slightly ahead of schedule.  If you’re worried, go ahead and head home now just to be safe.  It might just be flurries with little accumulation.

1. First band of precipitation is a bit early, light, but it appears some precipitation will show up over the Metro Area in the next 2 hours.  It’s been flurrying or snowing down the Valley and now even at Hebo (the town, not mountain) in the past hour.  Radar shows that band moving towards us.

2. Notice I said snow…again the mesoscale models are not handling the lowest atmosphere very well.  Check out the top of the KPTV Tower…I’m estimating it’s around 27 up there right now.  Models said low-mid 30s by now.  Low level airmass is still real chilly.  If it can snow in Eugene and in a valley at the Coast, it’s definitely cold enough to be snow here.  Good job by the NWS if that occurs.

3. Our 18z RPM (similar to WRF-GFS) has a more generalized band of precipitation moving over NW Oregon in the 5-7pm period, then heavier stuff after 10pm.  That’s a move forward in time by several hours.  Maybe that’s what we’re seeing on radar now.

4.  Southerly wind switch with a rapid jump in temps still on for after midnight…I have a feeling kids WILL have school in the morning, except in the Gorge.  The best I can get you kids is a two hour delay for most of town.

    wind is crazy here in ne buckman. snow globe snow just like someone else mentioned. i don’t ‘hear’ it. clearly more moisture to come! i really think we’re in the freezer here for at least the rest of the evening. i’m impressed with the radar echos. at least consistency is there for a few hours. love that it blows around and collects. hopefully roads won’t suffer too much for the commute. i’m at 30f with dewpoint rising somewhat at 22f. pressure at 30.03 after a high of 30.27. Did I mention that the NNE then gusty E wind is crazy? w00t & Burrrr

    I would think everyone would be happy the precip is evaporating. That means there is plenty of cool dry air in place. Light snow flurry right now Padden Pky in Vancouver.
