Unusual Dry Spell

Posted by Rufus La Lone on

Monday November 14

The month is already half gone.  So, too, is the rain for an unusually long period, given the time of year.  Here is the dry outlook.

DRY.  No rain is forecast between now and late Sunday evening, Nov 20.  North Vancouver Island may get a shot of rain on the 19th, but that is iffy.  Depending on your location, this could be one of the longest dry spells in the month of November in recent history.  October was similar.  By the week of Thanksgiving, the next rainy cycle should return.  

For this week (Nov 14-18), east-NE winds will pick up considerably out of the Columbia River Gorge & Fraser River Gap; subsequently, temps will remain on the chilly side (fog on & off in the southern Willamette Valley).  Subfreezing overnight lows in many locations out of the wind.  The cold Yukon Dome of High pressure that we mentioned last time remains in play, however, the coldest “core” of that Dome will remain east of the Rockies.  Still, the PNW will get another mini-shot of cold air east of the Cascades, which will, in turn, rush west through the Fraser & Columbia Gaps.  Not a super cold event, just a few degrees cooler than the previous few days.  Sat & Sunday Nov 19,20 will be dry & chilly.

Rain & Mountain Snow returns.  Breezy & wet on Mon the 21st, as the first in a series of Pacific storms moves onshore.  Models have varied considerably the past few days as to the strength of said storms, and in the precise timing.  So, expect on/off rain & windy conditions to prevail from Nov 21 through the U.S. holiday weekend.  Rain on Thanksgiving Day keeps appearing & disappearing on the charts.  For now, plan for the possibility of wet should you be traveling on the big bird day.  Black Friday is trending mixed like Thanksgiving Day - models are NOT consistent in their forecast for rain.  There will be 2 more forecast updates here before the holiday.   

Post-Thanksgiving - models continue to indicate stormy weather that weekend (Nov 26,27), with rain, wind and mountain snow on/off for those 2 days.  Chilly l& damp to start the work/school week on the 28th.
