May 2020 Weather discussion for the PNW

Nice day. 71/55 here with some morning drizzle and afternoon clearing.

[TacomaWaWx]

65/52 here. Meteorological summer is just a few days away now!

[Frontal Snowsquall]

This summer was decent. It wasn’t too hot in July.

Yeah, there was a stretch of almost 2 months of normal weather from mid June onwards. Then got hot again in August.

[Frontal Snowsquall]

HIO is still at 1.64” which is about a quarter inch below average MTD. Orographic lift zones have done much better than rainshadows this month relative to average*.

You should move out here towards the East side of Metro, been much wetter here. TTD is currently at 3.52", which is +1.16" above average at the moment. Also currently at +2.4 departure for the month heading into today.

Troutdale airport (your houses) averages have always seemed a little funky to me. Even PDX is down to +1.5

[TT-SEA]

Teeing off... twilight rates.

Your boy needs to point his front foot towards the target a touch more.

TTD has had some really warm lows this month due to the warm dry east winds blowing. There was a 3 day stretch earlier in the month where it only got down to 60/65/65 on three consecutive days. One of them was a midnight low and it only got down to 68 one morning. Very unusual for that to happen. I hope with this warm/hot finish to the month we can finish @ +3 or higher. That would be great!

It’s kinda sad to craft an entire persona simply to try to annoy somebody.

 

I often wonder who you were on the Fox 12 blog.

[Frontal Snowsquall]

Going to be a nice sunset. About to head out for an evening jog.

[El_Nina]

0.02" of drizzle this morning followed by filtered sunshine and clouds this afternoon. Nice day.

The global lower stratosphere is warmer than average for the first time since 1993. Usually those spikes are induced by vulcanism, but this time it was internally driven.

 

Interesting..

[VancouverIslandSouth]

Wow, that's an impressive Lift Index forecast for Oregon on Friday night:

 

[VancouverIslandSouth]

The 0z ICON shows a stormy looking pattern for Saturday with significant rainfall right from Northern CA to Souther BC:

Shank!

Bad time for golfing Saturday evening, if the 0z GFS has anything to say about it:

 

[TT-SEA]

Shank!

He was driving very well today. His putting game was not so good.

[GeorgeWx]

If if didn’t get hot earlier in June, then it would have been a late start to summer that year.

[Front Ranger]

Sounds like the opposite of me.

Going to be some severe thunderstorms forming. Watch out for possible tornadoes

[VancouverIslandSouth]

The 0z GEM is a bit drier but also shows widespread heavy rains on Saturday.

It’s been an interesting month. Hot the first part and now another heatwave late. The east winds have been strong and very dry low dewpoints at the start but also been a wet month. Lots of variation.

Pandemic-induced? Or low....

There was actually a relatively cool start to May. A lot of places had their coolest May temps in several years the morning of the 4th, in the wake of the cool troughing that was with us the 1st-3rd.

 

The second week certainly featured an impressive early season heatwave, though. Followed by generally cool and unsettled weather the last two weeks, and now another flash of warmth before we see a big crash with more rain and cool temps this weekend. Definitely a fun and dynamic month even if it ends up a little on the warm side.

[Front Ranger]

Spring still running on the dry side for most the PNW.

Yeah...We are doing just fine up here.

The mesoscale models will do a better job picking up on convection.

For sure, that’s a better analysis of the month. Portland is just under average rainfall for the month, I think we can finish above average if the thunderstorms pan out on Saturday

March and April were below normal in my area as I have mentioned many times... May was just a little above normal.

Congratulations! Good choice!

Left the house open last night because it was muggy, and it dropped down to 44 last night.  It's a little chilly.

[VancouverIslandSouth]

Another impressive rainfall map on the 6z GFS, all of that coastal band falls within 24 hours:

 

 

It reminds me of some of the coast thunderstorm outbreaks I've observed off the UK. Very rare to see this here.
