April Weather in the Pacific Northwest

[TigerWoodsLibido]

Friday looks crazy cold across the upper Midwest on the 12z Euro.

 

Also digs a deep western trough in the mid-long range.

 

Bummer that this type of pattern didn't happen back in Dec-Jan.

There are thousands of varieties that bloom from February thru June. One of my customers has a couple hundred and he documents their bloom time each spring. They were about 3 weeks late last year. Haven’t asked him how they are doing this year.

 

Yes... I know the early bloomers were a different variety.    They are usually blooming along the roads here by Valentines Day and they were about to start blooming when the cold hit.   I would say they were at least 3 weeks behind this year.    They started really blooming around the second week of March.

A gray afternoon with a temp of 50 about right now. Looking forward to seeing more spring color in the coming weeks. Pretty crazy seeing some Rhodies blooming already!

Again... these rhodies are actually late this year.    This type usually starts blooming by Valentines Day.   You see them all over the area here.

It's 47 here right now. It hasn't touched 50.

So many different plant varieties available these days.

Looks like spring did indeed fail to fully load. The pictures are gone!

Yeah... the image upload site must be down because the images were just Xs when I refreshed.  Trying another site now.

Bad omen...

Re-installing spring... file was found.

And this afternoon...

I think you are right.

Wow, the snow even melted up on the ridge line today.

I took another look at the impressive minimums in eastern Oregon during the last couple days of February. Seneca hit -21 on 2/27. They had also hit -33 in late February of 2011, which incidentally is the coldest reading ever observed in Oregon so late in the season. For Seneca, this means they have twice fallen to -20 or lower after Feb. 25th in the past 7 years. Prior to 2011, that hadn't happened since 1993, and prior to that, not since 1955/1960/1962.

Shouldn't some (most) of these posts be in the gardening thread?......... where ever that is!

[TT-SEA]

Judging by my facebook feed... people REALLY hate April snow and cold.   I am definitely not alone.

I would love nothing more than some dry warmth right now.

[MossMan]

Currently 38 degrees here at home, NWS calling for mostly rain at Snoqualmie ...not so sure I buy that. Guess I will find out early tomorrow morning when I travel over the pass.

Looking a bit breezy on Sunday

[TT-SEA]

More record cold...

12z GFS gets the low down to 968mb with a decent track. Might be time to start talking about a fairly significant storm.

12z GFS gets the low down to 968mb with a decent track. Might be time to start talking about a fairly significant storm.

Last night's 00z EURO had wind gusts up to 90 mph at the coast and up to 60 mph in the Willamette Valley with sustained winds around 40 mph. Still time for this thing to track even closer to the coastline to produce even stronger winds.

That's unlikely. A Vancouver Island landfall is much more probable given the climo of these things. BTW, 330 foot wind speeds don't translate to the surface. There's a lot more friction in the lowest layer right against the ground.

Yeah, negatively tilted trough with a nice jet streak rounding the bottom. Textbook stuff. The NWS actually mentioned "bomb" cyclone in their AFD. Save that hype BS for nor'easters. 

[Jesse]

Bit of a rollercoaster on the 12z GFS ensembles. Looks like a fairly interesting and active pattern coming up.

More record cold...

 

[Phil]

I would love a good windstorm right about now.

You can have ours...nothing more depressing than watching cherry blossoms get ripped off before they bloom.

 

Highest 5min sustained of 43mph and gusting to 52mph here as of 2:10pm on the ultrasonic unit. Weeeee.

...WINDY WEATHER POSSIBLE SATURDAY...

Windy conditions are possible Saturday over much of Western
Washington. A deep low pressure center is forecast by most weather
models to move north off the coast on Saturday. This will bring
strong southerly winds to Washington.

High wind is possible in some areas. As always, the exact track
and strength of the low will determine where and whether any high
wind will occur. The zones most likely to get high wind--sustained
wind of 40 mph or gusts to 58 mph--are the coast and northern
inland areas. Most other places exposed to southerly wind could
have wind in the 20-35 mph range, with gusts to 50 mph.

Details such as exact timing and actual wind speeds are unclear at
this point. Later model runs should sharpen the forecast. This
message is intended as a notification that windy conditions are
possible Saturday.

There will also be a period of heavy rain in the Olympics. This
could bring the Skokomish River to near flood stage late Saturday
or Sunday. Other rivers will experience significant rises, but are
not forecast to get close to flood stage.

That's unlikely. A Vancouver Island landfall is much more probable given the climo of these things. BTW, 330 foot wind speeds don't translate to the surface. There's a lot more friction in the lowest layer right against the ground. 

 

Yeah, basic meteorology states the sooner it wraps up the furthest west it will remain. Latest Euro unsurprisingly keeps it deeper and further NW with the landfall.

[TT-SEA]

Wind event looks unimpressive on the 12Z ECMWF... not much more than breezy conditions around here.   Hope this run verifies.

 

Good news is that Friday and Monday still look warm.   Bad timing since the weekend will not be nice in between... but I will take what we can get this spring.

The models have been hinting that this is going to be a double-barrelled low pressure system. These give the models fits and the exact track is more unpredictable than normal. From past experience these type of systems also track more closer to the coastline as it heads northward.

 

Some parts of the Willamette Valley are higher than 330 feet. The 330 foot map was created to give a good representation of winds where it can cause havoc. When it comes to wind storms, trees and higher structures above ground are the most prone to windy conditions. The map will likely verify from a sustained wind standpoint.

[TT-SEA]

Only about another 18 inches of snow to go in Minneapolis if the 12Z ECMWF 10-day snowfall map verifies.

I’m sure it will be a Columbus Day redux but hotter and snowier.

Crazy.

 

The great mountain snow pattern days 6-10 is showing up out here too.

Because it's just been non-stop wet misery so far.

March was pretty nice, I thought.

Indeed. Cooler and drier than normal month for most of the region.

Ending up warmer and drier than anticipated down here today. Lots of sunbreaks. Dry pattern continues.
