HRRR shows a decent c-zone firing up later this afternoon and into this evening.    My area will probably get hit pretty good.    Tomorrow looks drier though so that is nice.

Drove over to Corvallis and walked around the OSU campus. I’ll be back to stay in September!

The second pic is the greenhouses. I’m not fully decided on major and minor yet but my minor might be agriculture.

59 and mostly cloudy here. Figured may would be wetter but only 0.4” on the euro the next 10 days....still a whole lotta month left to go though. I wouldn’t be surprised if May ended up wetter than April this year like it did last year. 

Monthly rainfall-0.57”

Could end up being 1st or 2nd driest spring ive recorded. Record is 4.25” in 2019...at 3.84” currently so 2nd place is more likely.

Of course it’s a way different story west of the mountains.

Sure, but April is still relatively dry in Western Oregon and Washington compared to November through February.  Seattle and Portland average about 2.5 inches in April, compared to 5-6 inches in the wettest Winter months.  A 1.5 inch deficit for April is better than a 4.5 inch deficit in December or January.  And actually heavy rain in April in the mountains would erode the snow pack faster than drier weather.

Would much rather have a drier April then in any winter month.

Unfortunately the sun is in the process of expanding and eventually it will get close enough to evaporate the oceans away.    That will be an incredible salt flat some day.   Get a dune buggy now!

Idk. It’s pretty rare to get warm rain in the mountains in April. Usually if the pattern is active the upper airmasses are still sufficiently cool for snow at pass level or above. Snowpack situation would be a lot better for Oregon right now if it hadn’t been such a warm and dry month.

Drier weather in the winter can mean cold and snow, at least on the west side. Wet weather in April is always nice since it makes things look lush and green. This was a record or near record dry April and March/April combo for many areas on the west side so it’s pretty notable, and has been largely responsible for putting much of Oregon and SW Washington into moderate drought conditions.

2nd driest March April combo on record here this year with 3.84” only bested by 3.73” in 2019.

Imagine the temps in the Marianas Trench. Death Valley will seem sub alpine by comparison.

Go Beavers! I graduated from there with a B.S. in Horticultural Science.  Of course that was 30 years ago, but it's still a great school.

Pretty ideal precip distribution on the 18z GFS. Hopefully it sticks. At the very least, substantial Oregon precip starts as soon as hour 120.

Nice!

Jesse should be here soon to puke all over your pics.  😀

Wetter than normal water year... wetter than normal year to date... mountains have almost 150% of normal snowpack... and you take joy in the small things like a sunny day in western WA.   If there was a way to puke on your photos 20 times I would!

You really do have way more of an issue with what others post and think than any other person on this forum, and it's not even close.

The 00Z ECMWF was much drier than the last few runs with that late week trough.

Partly cloudy... but probably cloudy at times.   Clouds are bubbling up with the sun.

I am out mowing a sopping wet lawn right now.   Feels like May!

Wedding went off without a hitch! And it didn't rain on us, it came through overnight!

Looks like Springfield managed to pick up a half inch of rain but the airport only had 0.33 good lord what a disaster.  And it looks like more warmer and drier than normal weather on the way...shocker.

Glad everything went well for you! 

Yeah, May doesn't look incredibly wet anywhere. That could change late month going into June hopefully.
