August 2015 in the Pacific Northwest

[UnionWX]

Temperature just fell from 50 to 33 in 4 hours at Camp Muir.

Impressive.

UW picked up 1.09" of rain in an hour and 0.83" in 27 minutes.

I think easterly flow aloft is going to reduce rainfall totals here.

 

Doesn't appear to be much of a factor at this point.

Wow, very impressive. This event is way out-performing any models for the central Sound. Much more of a convective element to things than your typical deformation zone, as evidenced by the heavy rain and numerous lightning strikes.

[luminen]

Gloomy and mostly rainless here today. At least it's not the sweat-fest of the past few days.  <_>

[TT-SEA]

Yeah sort of... downtown Seattle has had about 10 times as much as here today. Usually indicative of easterly flow aloft. Should change later this evening.

Right, a lot of that is just a function of where the low is at and its slow movement east. It hit Seattle first, and the overall flow has favored them temporarily. Your totals should be quite healthy when all is said and done.

I think upslope against the Olympics caused enhancement over there. It's losing steam now.

[TT-SEA]

.89 at SEA today... very wet week now.   

 

And now well above normal for the entire month of August and its only the 14th!

 

So much for a record dry summer.

Probably a little. But this isn't a winter storm we're talking about...it's pretty weak in comparison. So upslope and whatnot is not going to be as much of a factor, like in winter when you see the Hood Canal with way higher precip totals due to strong easterly flow.

 

It's simply been a very juicy, convective deformation zone, with slow movement.

[Deweydog]

Kudos to the models. They handled this thing really well from a good 4-5 days out.

[TT-SEA]

SEA is now at 1.03 for the day and 1.33 for the month.

 

Over 150% of normal for August.

 

When will this end???

Just in time for kickoff.

No doubt. Pretty funny considering the 12z 1.33km WRF showed a mainly dry afternoon for most of the Sound:

1.18 at SEA now.

 

Won't touch the daily record of 1.60 from 1968 though.

[bainbridgekid]

The Blob strikes again.

 

[bainbridgekid]

You don't see many Midnight highs in August, but it looks like SEA may have pulled it off today.

A pretty drab and uneventful day up here... I picked up just .1" of light rain.

Not even a drop of rain here today.  Pretty windy this evening though. 

 

Tuesday and Wednesday are looking pretty warm next week.

Canadian model has gone from downright stormy and cold for next week on the 00Z run yesterday to perfect summer weather on tonight's run.   Completely different.   

[TT-SEA]

Ended up with .85 here for the day.

 

Over 3 inches of rain here in the last 3 weeks... with 2.20 inches on the weekend of 7/25-26.

[MossMan]

Been a while since we have had a good old pscz here! Been raining all evening. Don't know what my rainfall total was, but this would have been a very wet day even for November standards!

[TT-SEA]

Wait... according to this map, the entire eastern half of the Pacific Ocean, with the exception of a tiny patch just off Baja California, is from 0.25 to 5 degrees warmer than normal.  That can't be right, can it?

 

Confirmed...

Next week is trending warmer and warmer.

[Guest Winterdog]

Just looked at my rain gauge and was surprised by the additional .65" received since midnight bringing the total for this event to 1.89".

It hasn't been very wet for a couple years now and this summer is just making it worse...

 

Not much rain here yesterday.

Averages are getting cooler!

[MossMan]

I was thinking my area must have gotten at least 1.5". Really need to get a rain gauge. Anyway my yard had that feeling like it was just beginning to thaw from a long freeze, that surface squishiness but you could also feel the firm layer as well. The ground had become hydrophobic since it had been so dry, the moisture was having a hard time breaking through that hard layer. Also we had a lightning strike very near the house yesterday that caused our well pump relays to fry so we were without water for several hours...never fun. Crazy day indeed!

[Tyler Mode]

73.5 for a high today.

 

Dewpoints in the upper 40s now and skies are clearing.  Should be a nice cool, crisp August morning...before the heat of mid week arrives.  Ugh.

Looks pretty short-lived.

Good read... about a really good day.

Just breaking the 75 year old record for 90+ days at PDX. No big whoop.

That's the great thing about him and record warmth or record cold. He'll always find a way to objectively minimize it.

A day in which you expected hardly anything.

Upper 90s are looking possible Tuesday too, which is impressive for the latter half of August.

My comment had nothing to do with records. It was a simple statement about the length of the warmth next week. Minimizing anything never entered my mind. Goof.

?

 

Not true at all.   I knew it would be an interesting day for western WA... just was not sure how it would play out in my area.   I knew it would take longer out here.   Models were all over it for days.

I was being ironical. Lighten up, dilly bar.

Eh, 8-18 isn't too far into the periphery. Should be a hot day, though. 100 not out of the question.
