The Week Ahead – Losing Count

Sunday and most of Monday appear to be the relative calm before the storm(s) mid-week.  It should be dry with partly to mostly cloudy skies today.  For Monday, models are mixed as to whether a weak disturbance brings lighter rain back into the forecast or may stay mostly dry during the daylight hours.

But the real action looks to move in Tuesday and Wednesday.  

I’ve lost count on the number of storm centers that tease our state but drift northeast into B.C.  Close enough to kick up gap winds caused by the Low pulling over Higher pressure east of the Cascades.  Well, this looks to be partly the case again Tuesday, though as of now, the foothills should be positioned under more of a SE-NW gradient and much quicker progression.  More characteristic of lower gap wind gusts followed by gusty and rainy widespread conditions across much of Western Wa., not the persistent howling from the east. 

Wednesday is where things look a bit different for a change.

Per the Euro model baseline ensembles, a Low looks to track right into the Puget Sound region.  However, at this point, it doesn’t look very deep.  The key will be the developing Low and the tracking S-N pressure gradient as to whether Western WA will get some damaging southerly winds out of this.

Euro model Wed 1/13 10 am

Longer range, nothing special is currently apparent.  Thursday may be a dry day after the Tues-Wed action, followed by another mundane round of rain Friday.  Shower possible into next weekend, but with more potential dry periods.

Rising snow levels look to be a factor Tuesday and Wednesday as we look to draw in significant moisture from the southwest.  As of now, it looks like just as much rain as snow for the lower elevation passes (e.g., Snoqualmie Summit)..:(

Have a great week!
