Colder Wx Possible

Posted by Rufus La Lone on

Halloween 2022
 
Boo!  Colder weather on the way, with the threat for snow/rain mixed over NW WA late in the forecast period.  Mug up.
 
The wet pattern will continue on & off for the next couple of weeks.  Key will be the positions of Low pressure ‘cells’ moving in from the Pacific along with a colder air mass pooling over the interior of BC.  For the next 24 hrs, moderate-to-heavy rain is expected over OR today, with showers & possible thunderstorms on Tue for all the region.  Clearing by Thu morning will mean FROST possible, both sides of the Cascades.  California will receive a bit of rain early this week, as well.  Another wet system moves into the PNW from the NW on Fri, so NW WA & Vancouver Is. will wet first.  Rain will spread into OR & ID overnight Fri.
 
The coming weekend looks to turn colder, as the back side of Friday's storm drops across the region on Saturday.  WET & blustery.  Overnight Sat, colder air will be combined with the moisture to set off snow/rain mixed showers, esp north of Chehalis.  Wow, that’s early.   Cold showers for the rest of the PNW, with snow levels dropping well below the passes from the central OR Cascades north.  A bit of drying on Mon the 7th before another Pacific storm arrives on Election Day.  This one could be interesting in that cold, ‘winter air’ will pool and be threatening to push out of the Fraser Gap, mixing with the moisture from the west.  Not saying a snow event, but it will be close temperature-wise for Bellingham north.  WINDY either way on Tue & Wed, Nov 8,9.  Rain will fall across the entire PNW, as well.  
 
There are two scenarios for what happens after Election Day.  Stay with us.  One scenario re-introduces the chance for colder air to push out of the Fraser Gap, keeping snow levels just above sea level in the far NW corner of WA, with a chilly rain elsewhere.  In addition, by the weekend of Nov 12,13, that cold air from the Yukon & interior Canada will rapidly flow into the central USA, setting of all kinds of rough weather, from WIND to SNOW in many places in the heartland.  For the PNW, that weekend is trending DRY and relatively mild, as the colder air heads east.  The other scenario keeps the PNW mild with a couple of STRONG WIND storms after Election Day heading into the weekend of Nov 12, 13; holding back that cold Fraser Outflow, with the snow flake tease, until Sunday the 13th and chilly afterward.  We’ll update all this as the time nears.
 
Bottom line: colder weather is possible in November.  Not too unusual, but compared to the very mild pattern in October, the change will be abrupt.  Pull the heavy coats out of the closet; they may be needed.

Normalcy

Posted by Rufus La Lone on

Friday October 28
 
A decent pattern of rain, showers, sun breaks and mountain snow is now in place.  The specifics per day may adjust, but at least the west coast is out of the dry, blocking ridge issue and precip has returned.  Refill time.
 
Overall, the Puget Sound & southern BC will receive the brunt of the moderate-to-heavy rainfall over the next week, starting now, with a frontal boundary sagging over WA and OR as the day progresses.  The next system, which will be stronger & longer lasting, is on tap for late Saturday into Sunday.  This one will also bring precip to OR & ID, mainly 12-24 hrs later.  Also, COLD air will be abundant on the backside of this cold system, so expect SNOW level to drop well below Cascades passes after the front passes.  Halloween will be showery, blustery and quite chilly! Showers will prevail through Tue. 
 
! FIRST FROST is possible, if the sky clears in your location, next Tue, Wed and/or Thu mornings.  Use this weekend to protect plants that may be on the patio; detach hoses.  The next wet, but weak, system may clip the PNW late Thu into Fri, with a nice break in the action for the weekend of Nov 5,6.  FOG issues likely that weekend.
 
The week of Nov 7-11 is modeled to mirror the week before, with a WET, cold system dropping in from the NW overnight Sunday Nov 6 carrying plenty of precip, chilly air and mountain snow.  Raindrops will be heard on Election Day.  It could be wet through Wed; windy on the 9th, as well.  Clearing Thu, with relatively mild temps & fog again.  For now, we may see dry weather to end the week (Fri 11th) on through Sunday Nov 13.  Note that some model scenarios bring in windy, WET conditions that weekend, but the trend has been away from the damp solution.  We have time to finalize that forecast period.  Daylight savings time ends Sunday Nov 6.
 
There are always variations 'on the theme' when forecasting long-range.  However, the basic pattern in the upper atmosphere has turned favorable for what one would expect in the PNW during November.  Normalcy.

The Sound of Rain

Posted by Rufus La Lone on

Monday October 24
 
Ah, rain.  Plenty more to come.  Refill & sip on.
 
There is variability in timing of the next series of wet systems, so we’ll simply forecast on/off RAIN all this week. Thu may not end up the dry day after all.  Systems are 24 hours or less apart, with showers and partial clearing in between each Pacific front.  Raincoats needed daily.  The coming weekend may begin a Triple Punch.
 
Three strong systems are modeled to arrive starting late Saturday night, Oct 29 with WIND and moderate rainfall, esp for western WA.  That’s #1.  Number 2 hits the PNW Sunday night or before sunrise Halloween morning, with a bit stronger winds, per current prog charts.  The 3rd, which could be the strongest of the Triple Punch, slams into the region on Tue November 1.  HEAVY rainfall for western WA.  Localized flood issues may arise in portions of western WA, particularly the NW corner (western BC will be slammed, as well).  Note that model scenarios do have a variance, so the second storm may not materialize.  Either way, these systems will be notable for the amount of precipitation & gusty winds.
 
The PNW will be granted a ‘dry out’ period starting Wed Nov 3, which may last through the following weekend of Nov 5,6.  Don’t make outdoor plans just yet.
 
A long, but pleasant quote, from John Muir:
“Good luck and good work for the happy mountain raindrops, each one of them a high waterfall in itself, descending from the cliffs and hollows of the clouds to the cliffs and hollows of the rocks, out of the sky-thunder into the thunder of the falling rivers.  Some, falling on meadows and bogs, creep silently out of sight to the grass roots, hiding softly as in a nest, slipping, oozing hither, thither, seeking and finding their appointed work.  Some, descending through the spires of the woods, sift spray through the shining needles, whispering peace and good cheer to each one of them.” -John Muir, 1869.
 
We welcome the sound of rain back to the PNW.

The Change

Posted by Rufus La Lone on

Friday October 21
 
Finally Fall - the kind of fall that residents of the PNW expect.  Wet, windy, chilly and fire-stopping.  The change is upon us.  The image below was taken (by your host) here in Albany this morning.  "Pink in the morn’n, sailors warning.”  Ready?
 
The long awaited Fall rains are arriving later today, Oct 21.  The first couple of systems will be damp, for sure, but the stronger, heavy rain systems, with plenty of WIND, are on tap for next weekend and beyond.  As of now, we see a very limited amount of ‘dry time’ out of the next 16 days!  Take a sip, details are next.
 
Wet this evening into Sat, with showers overnight into Sunday.  Sunday should be mostly dry, cool.  The next system arrives after dark Sunday, and keeps the region damp through late Wed.  (NOTE: there have been a couple models runs suggesting a tightly wrapped Low moving into OR on Tue, with strong winds.  An outlier, but it illustrates how rapidly deepening Lows off the PNW coast can develop into wind producers.)  A few of the strong systems coming to the sky near you may be remnants from typhoons far to our west.  Onward —
 
Late Wed through daylight Thu Oct 27 should be mostly dry, cool.  Use the time wisely in getting gutters and storm drain grates clear of leaves.  The big storms cometh.  The last weekend of October is charting to be very wet & windy.  In fact, the charts keep the entire PNW in ‘drench mode’ DAILY for 7 days, Oct 29 through Nov 5.  Sunday Nov 6 should begin a short dry-down period, but it will be November chilly.  California will also get in on the action, esp late in the forecast period.  Halloween & Election Day will be wet.
 
Overall, fire issues from Canada into California will be taken care of with the moderate rainfall.  Current projections are for 2” to 4” of accumulated precip in the lower elevations during the next 16 days; higher in the coast & Cascade ranges.  Be prepared for slippery roads, clogged storm drains, wind issues (possible).  In a word, FALL.

Good News

Posted by Rufus La Lone on

Monday October 17
 
There may be good weather news on the way.  Got your morn’n Mug ready?
 
Patrons that have ‘Mugged around’ this virtual Café for several years, will recall that often model solutions revert back to earlier forecast outlooks.  Well, that may be the good news today.  The long hoped for change to a wet, Fall pattern is back on the charts for this coming weekend, Oct 22,23.  Indeed.  Thursday & early Fri should mark be the transition into a cool, wet weekend.  Windy, too.  Beforehand, wx conditions will be smoky/hazy at times before an onshore flow picks up on Thu.  Temps will be moderate in the 70s.  The pacific High will shift farther west, opening the door for wet systems to FINALLY work into the PNW.  Rain should arrive late Friday (+/- a few hours); Sat will be wet, breezy and definitely cooler than what we have experienced this Fall.  
 
Sunday should be the ‘in between’ day, so expect sun breaks, scattered showers, coolness.  The second system will follow in a similar track, pushing into the region late Sunday for a wet start to next week.  Temps will be cooler yet.  Snow level will drop dramatically by Monday afternoon the 24th, so don’t be surprised to see The White if you travel to the east side.  Temperatures will be cold enough Thu morning east of the Cascades for the FIRST FROST, if the sky clears.  The Monday system will linger and drop into CA by mid-week (good news there, too).  Models are mixed for the middle of next week: could be damp or dry.  We will call it mostly dry Wed - Fri Oct 26-28 next week; fall cool.  
 
The last weekend of October is currently trending DAMP,  although a few model solutions hold off more rain until late Halloween.  The latest projection is for a disturbance to arrive Sat the 29th, which, if verified, would become the strongest storm yet this season -- bringing plenty of moderate-to-heavy rain, wind, and another step down in the temperature dept.  We’ll review this in our next report.
 
For now, let’s keep our Mugs ready for blessed, fire-damping RAIN to return to the PNW by the end of this week.
