North wind gusting to 25–30 creating some nice waves once again.  Had a high of 62 just a bit ago.  The sound is still angry and T-towns outdoor furniture pillows are now in someone’s yard in Olympia :(

Definitely still windy but no pillows down today!

You take awesome pics.

For everywhere wondering/speculating about where I have been, I am very flattered We have been on a road trip to Grand Teton and Yellowstone this week. Took a nice week off before starting a new

Getting married tomorrow so that’s why I’ve not been around a ton of late. Looks like we are about 68F out there and are ready for some much-needed rainfall overnight.

Well I haven't been around in a while. Been a little, erm, preoccupied. Hope everyone's enjoying the sunshine and warmth lately! I'll be in Arizona for the weekend, and hopeful I don't melt!

Some really low dew points this afternoon.  Me bets some places will reach freezing again tonight.  It dropped to 31 here last night for three in a row and 4 in the last five days. 63 / 31 on the day.

I've never seen such a persistent continental pattern in April before.

Pretty incredible to see almost every station from the WA Coast to the eastern border of ND having brisk to strong north winds at the same time.

62/35 here 

Feel like I’m living in Troutdale again with east winds (except their north) coming out of the gorge. Crazy fun pattern right now at least for me.  I’m entertained :)

Just a bit different on the eastern side of the section... here is a live view from Minnesota.     Quite different than the spectacular weather and warm sunshine we had today.  👍

SEA had a northerly gust to 36 today with the dp down to 19 at one point.  Very impressive on both counts.  This is as continental as it gets in the spring.  No doubt some places will freeze again tonight.

I really hope we get a week of good soaking rains before summer.  We could be in big trouble if we don't.  I love Canadian airmasses, but they are as dry as a popcorn fart as my coworker used to say.

I must say it's really weird to have a day like today and still have the trees skeleton bare here.  I went to Auburn today and the trees are starting to leaf down there, but here they are still very bare.  I actually think that the leaf out being so retarded this year helps keep the dew points down at night due to the trees not contributing moisture to the air.  Just a theory.  No doubt the dry ground does contribute to lower humidity and bigger diurnal ranges.

I think the low dewpoints are slowing down the trees leafing out.

This is definitely true. Very noticeable here in the spring/summer. There can be a 7-8°F difference in dewpoints between forested locations and areas with little to no trees.

I happen to live in perhaps the worst location for humidity in the entire DMV..surrounded by old growth parkland and water on three sides, near the bottom of the Potomac River valley. This location literally self-manufactures disgusting humidity during the warm season.

Seattle record for consecutive 70+ degree days in April is 5 from 1897, 1926, 1934, and 2016. Seems they have a good chance to tie that and an outside shot at breaking it.

This is a pretty crazy pattern as I'm sure you have all noticed.  We're about to see the EPO drop to -6 while the PNA is only a modest +2.  I think that explains the cold night thing pretty well.  With a huge +PNA block that aspect wouldn't be there.

Already down to 44 here tonight.

I think that is part of it for sure.  Dry air creates a chilling effect for plants when the leaf moisture evaporates.

Once again most of the years are long ago.  This pattern was more common in the spring prior to 1960.

It appears the EPS is split on how we will come out of this pattern.  Looks like a mix of retrogression and / or undercutting westerlies.  A cold finish to the month wouldn't be that surprising.

You have no way of knowing that.   We could get a wet week sometime just before summer which would really help.

A wet week in early summer, especially if followed by anomalous dryness, would be incredibly bad. Resultant plant growth could act as a tinderbox.

The only way to prevent a bad fire season would be for consistent precipitation throughout the entire summer. And with how August and September are looking to pan out, that's appearing increasingly unlikely.

41 here this morning... looks colder in the lower spots around the EPSL though.    We had light breeze most of the night up here.    It so dry that there is not even any dew.

So this popped up on my FB memories this morning from 2011. 

 

 

IMG_0753.JPG

 

I was surprised it got as warm as it did yesterday, and how slow it was to cool down last night.  Currently 37 with the sun starting to peak over Squalicum Mountain.

Dropped to 34 here last night.  Not bad considering the surface pressure gradients were a bit unfavorable for max cooling here.  Places nearby dropped to 30.  At any rate a remarkable 33.2 average low for the month to date.  I was pretty pleased to see that SEA managed to get below 40 again.

The situation gets pretty interesting for potential huge diurnal temperature spreads for the remainder of the week as surface gradients become favorable for max radiational cooling for many places while also being favorable for the days to get quite warm for this time of year.

The latest model runs look good for a pattern change around the 20th which looks increasingly likely to last.

You could say we are in a bit of an abnormal pattern.  Pretty easy to see the difference in observed weather with an EPO block vs a big +PNA block.  The EPO block gives us a much cooler nights and drier air.

The cold nights are going really offset the warm days for daily averages.  As I've mentioned before this is very old school stuff.  I might have to do a special thread to explain that.

Looks like SLE made it down to at least 34 this morning. We got down to freezing as the wind slacked off after midnight. 

My Dad took 3 days off to burn debris from the ice storm, and now Marion County has a burn ban in place through the 19th. The old man was disappointed.

Got frosty again in Everett. Some of my flowers are already dead but I'm thankful I haven't started the overseed on the lawn.

This has certainly been the most incredible run of cold nights I've seen this time of year.  OLM dropped to 28 last night.  Their combined numbers for March and April on low temps have been insane.

Ya, I have lost count of how many mornings of frost we have had the last month, but it's nice to have that nice clean crisp air every morning!!

12Z GFS shows a weak little ULL early next week... but the real pattern change holds off until day 10 with rain moving in at that time.   I am bit skeptical about things turning more progressive pattern with that cold trough anchored in the middle of the country.
