March 2020 Weather Discussion for the PNW

[Jesse]

Thunder!

 

It’s managed to stay pretty chilly today despite numerous sunbreaks too. High of just 49 here so far.

[TacomaWaWx]

Kind of in the dead zone currently...partly sunny here most of the day with no rainfall here. Most of the activity has been a few miles south of here and north of Seattle. 49 at the moment.

hail falling

[MossMan]

Had a vigorous thunder storm with up to half inch hail a while ago. Video won’t upload but here is what’s left

Nothing here so far this afternoon.

[TT-SEA]

Nothing here so far this afternoon.

 

 

Just a couple short hail showers here with a fair amount of sun... and still dry now.

[Timmy Supercell]

Tornado reported near Richland, WA just a couple hours ago, and a 6.5 earthquake in Idaho after that!

[jcmcgaffey]

Pretty good size hail (a little bigger than pea sized) and lightning here just north of seattle.

[Deweydog]

[jcmcgaffey]

Have had 3-4 separate hail showers today.

[Timmy Supercell]

Spring can be VERY frustrating.

 

[jcmcgaffey]

Washington state snowpack is officially over 100% not even counting current weather. Good time of the year to be over 100% too.

[Frontal Snowsquall]

Tornado reported near Richland, WA just a couple hours ago, and a 6.5 earthquake in Idaho after that!

Yikes! The last thing we need are natural disasters to go along with this global epidemic.

[Deweydog]

Lots of hail and virus in the shade at the Orchards Fred Meyer.

Just need Yellowstone to blow and do us all in!

Looks like 52/40 at SLE today. 43/34 here. Good for a -3 departure for SLE. 

[Kayla]

Felt that 6.5 quake in Idaho out here. Had the lamps moving around and a very slight rolling motion. 

[VancouverIslandSouth]

A fair amount of watering down from some of the earlier runs, in the winter this bust would have been more noticeable. A few days ago the GFS was showing 925mb temps around -5c or colder for awhile; now it barely hits -2c. Still it's amazing how persistent the NW flow has been.

[SilverFallsAndrew]

Nice evening.

These days walking the garbage can down to the end of the driveway is exciting!

Down to 37 degrees. .31” of precip on the day.

[Dan the Weatherman]

People think of +AO as a “cold arctic” pattern. But that’s not true at the surface during the arctic winter.

 

It’s a cloudy, windy, anti-radiative pattern in the absence of sunlight. It flushes old/thick ice into the NATL, and slows refreezing.

 

So the basin is subsequently more vulnerable to meltout come summer. Just the worst possible combo. That +AO circulation even slows the Beaufort Gyre (the BG holds MYI in place in the western Arctic for several years at a time, allowing it to grow). That can have decadal scale consequences depending on the persistence of patterns.

 

It’s a terrible pattern to have during the winter.

 

Do these patterns that you have been mentioning here that lead to more ice being flushed out of the Arctic tend to be more prevalent during the warm phase of the AMO (+AMO)? You mentioned that the ice was building during the 1960's and 1970's, which was a period of -AMO, and I have noticed from looking at Arctic sea ice extent graphs, that the Arctic ice extent has dropped rather precipitously since the AMO went positive in 1995.

49/36 day. If we don’t get any rainfall before midnight it’ll break an 8 day rainfall streak here.

When your 99 and a half your going to hate garbage day! 

until then.... Enjoy

[Blizzard777]

I was shadowed today

zero precipitation 

39* currently 

[TT-SEA]

The GFS has been shifting the troughing steadily north next week over the last few runs.   00Z run continues this trend.     I know... it would be terrible to have a couple dry, sunny days per the trolls.    

[jcmcgaffey]

49/36 day. If we don’t get any rainfall before midnight it’ll break an 8 day rainfall streak here.

wow crazy you haven’t seen any precip. Up to .67” on the day here

When I was down with the flu I used my truck to haul the garbage and recycle cans down to the road...I will just do that again when I’m 99!

The gfs has been too cold in the mid range with pretty much every troughy period this winter.

Very little precip here either... not sure how much a couple 5-minute hailstorms adds up to in the bucket.

I'd swear you get more dogs every year.

[ShawniganLake]

0.01” on the day here. But that was melted frost from this morning. There were a few widely scattered ice pellet showers around the area.

it was sort of a broken up convergence today just north of Seattle with continual light thunderstorms. Nothing too crazy but was pretty active.

0.44" today makes it 4.89" total for March.

[Cloud]

Just stepped outside for a smoke and my goodness it's COLD. It's as if my body didn't expect it at all. 

[Cloud]

Apparently there was a 6.5 earthquake in Idaho this evening around 5:52PM. Did anyone felt it? I was taking a nap. 

[TT-SEA]

The 00Z GEFS does not agree with the operational run for next week... darn.

 

00Z GEM looks nice though.

boy not just a casual disagreement, the 00z GFS operational looks like it wants to have nothing to do with the ensemble
