Have to get to work early today for something else, but my eye is sure drawn to this…
Both the WRF-GFS & NAM-MM5 forecast a significant windstorm in the valleys Sunday midday/afternoon. Deepening surface low moves inland over Washington, isobars are perfectly aligned, and 15-20 millibar pressure difference Eugene to Olympia. Wow, that’s like what we saw in December 2014 or stronger. 50kt gusts forecast over metro area at the surface.
Yet…ECMWF says WHOA!, the low is headed into Vancouver Island instead and it’s just regular breezy here. In fact none of its ensemble members from last night, or the operational run this morning have the low close by.
It’s an epic model fight but one we’ll be watching VERY closely…more later today.
