September 2019 Weather Discussion for the PNW


Requiem

Recommended Posts

13-14 repeat would be great. S valley got the nice early Dec event with 5-7" of snow around Eugene/Springfield and temps getting to -10F tying the all-time record low.  Then the great early Feb instance with a cross-cascade mountain wave event and lots of snow.  Was a Willamette Valley Special for sure.

That was a special treat. Two terrific events in the same winter. We got more snow than Tim and Timmy_supercell, which is pretty shocking. But we did not tie our all time low, which is -12.

I’m sorry summer got off to such a late start.

 

We’ve never seen a late summer make landfall before. Unprecedented.

And it even got a like from Tim, which is funny because it’s that exact same instinct that makes you weirdly protective of him. ;)

It appears that Trump used a map today from 4 days before he made his Alabama mistake... because the track has shifted dramatically when he made the comment about Alabama on Sunday.

 

And then on top of using a map from 4 days earlier than his comment... he also appears to have drawn in a line with a marker on that map to include Alabama.   You can't make this stuff up.     :lol:

Heard that people in Louisiana are bracing for impact.

Ryan Maue, the voice of reason in this, had a good thread about it.  I did not know the NHC has a 7 day cone that they do not show the public.

 

  1.  
  2.  

    Insane people: Extrapolating the NHC 5-day cone of Hurricane #Dorian is most definitely an impeachable offense. Normal people: yeah that's probably a reasonable extrapolation into Day 7.

     

    The NHC creates an internal 7-day forecast -- not for public consumption -- but will in future years. The huge 7-day cone would definitely be over Alabama for Hurricane #Dorian even though there was ~0% chance of a direct landfall. This will lead to further confusion.

     

     

    Maybe it's a good thing we don't issue 7-day forecasts yet. Had I advised the President on Wednesday evening, I'd probably have told him that #Dorian could cross the peninsula into the Gulf and end up in Alabama, sort of like the WPC 7-day surface prog.

     

     

    Thankfully, the acting NOAA admin Neil Jacobs was asked to personally brief the President with trusted, accurate information. The threat to Alabama quickly went to zero as new model data arrived. But, Trump's Tweet didn't reflect that new info.

     

     

    In summary, the "Alabama" Tweet was based upon stale information. The motivation was obviously to inform the public & update on Dorian. Nothing nefarious. Just admit it an move on, right? Nope. That's not how this works between media and Trump.

Takes a moment to load but cool animated shots

Just fascinated how Dorian is following the contour of the East coast!

 

Currently 73*

Interestingly enough, PDX's all time record warmest min was actually set on 2/2/1950 and they haven't really come close to beating that record even in recent "warm" years.

 

23 of PDX's record warm September mins have come since 2000.

 

13 of OLM's have.

 

The warm years have been "warmer" at some locations.

Not sure how reliable the records are there but going back to 1929 at HIO, 16 of September's record warm mins have come in the 21st century. The record is supposedly 66 on 9/6/1958 during a big heat event, though that seems dubious considering PDX had a min of 49 that day.

Battle Ground, another reliable long term non urban station near Portland, has had 11 record warm September mins this century.

 

Plenty of proof that PDX's records are pretty cheap these days.

Hard to beat 2 Arctic Blast in one winter.

This is the first time he ever heard of a category 5 hurricane. Give him a break.
