A Dry Record On The Way?

We’ve seen 10 dry days in Portland as of this evening, and we likely have 5-6 more.  Did you know we’ve never seen more than 15 consecutive dry days in May?  That would be this coming Saturday.  If we make it all the way through Sunday dry, we’ll have a new May record.  I’m especially proud that I can blog about this before Steve Pierce (a regular here and Oregon AMS President) has a chance to put out a press release about it.

A pretty good marine push this afternoon and evening has dropped temperatures much more quickly than last night.  At 1900′ on the KPTV tower in the West Hills, it’s running about 11 degrees cooler at 9pm versus Sunday night.  So after the 3 days in the 80s, we’ll be about 10 degrees cooler tomorrow (upper 70s).  Then a bit more cooling Wednesday, but little in the way of cloud cover.  Our RPM keeps insisting that tomorrow’s morning low cloud cover will be mainly south of the Portland Metro area and won’t last long; we’ll see.

A weak upper level trough passes through the Pacific Northwest Thursday and Friday, bringing below average upper-level temps and much cooler weather down here.  Still, there appears to be very little moisture for rain.

After brief ridging this coming weekend, models are all pointing to a very wet week next week.  Of course that’s the week leading to Memorial Day…hmmm, sounds familiar

Speaking of Memorial Day, I received this picture from Dave Shiffer today:

It’s Trillium Lake still ice-covered on Saturday.  He says the road was plowed to the dam, but campground and boat still under maybe a foot or so of snow.  I was surprised, considering SNOTEL sites show little or no snow there.  I suppose Sunday, Monday, and now Tuesday up around 70 or so will melt that ice real quickly.  Looks to me the campground will probably be open for Memorial Day Weekend (2 weeks to go).  One more reason I avoid camping in the mountains Memorial Day…too cold, sometimes wet, and often snow left lying around.  I’d rather wait until mid-late Summer.

I’ll be on vacation the rest of this week; time to stain the decks and go camping, so no posts again until next Monday.  Unless I get really bored…

    Today the visibility is MUCH much better. 😉 I wonder if that cold front scoured the haze out?

    Coming home from Portland Dad said this evening is a lot better.

    Why is it on days I CANNOT go to the viewpoint the visibility is perfect but as soon as I make plans to go there it’s as if Mother Nature says “Kyle is going to the view point! I better yuck it up for him so he cannot see anything and waste the gas!” 😉

    34 this morning? Didn’t see that coming…

    So, any idea why it’s 64 and clear in Kelso, and 75 and clear up here? We’re not very far from Kelso and that seems like a big difference in temp. Some type of inversion maybe???

    • bgb41 says:

      Approaching upper trough is deepening the marine layer causing high pressure at the surface to form off the Washington coast. Since the columbia river is a sea level gap to the ocean, the marine air floods into Kelso/Longview but areas north and south are not affected. Very typical during the warm season for this sea breeze to affect that local area.

    • Wendy-Silverlake, Wa says:

      That makes sense. That explains why it was the same way the other day. We probably burned off the clouds faster here as well, that might have helped bring the temp up a bit more.

  5. Mr Data says:

    Has anyone noticed that Western Weather forums act very childish?

    • W7ENK says:

      I’ve never been on Western Weather Forums. I stay away because I’ve heard it’s overrun with trolls, wishcasters and whiners. Been told many a time that it’s a zoo, so I have no interest.

    • bgb41 says:

      I have never posted there either

    • boydo3 N Albany says:

      I posted there a few times but my shields could not handle the continuous hammering of scat balls. Once my resistance reached critical level I used the last of my remaining power to zoom to a friendlier blog. A place where air and water are prevalent. One might say, a breath of fresh air 🙂

    • gidrons says:

      I’ll read the solar activity/climate change posts over there, that’s about it. Oh, they’re often mean to Jesse but the moderators eventually pulls those comments.

    • gidrons says:

      @Eric, definitely loaded with whiners. They get weiner tags attached to their name.

    • W7ENK says:

      Wiener tags??? 😆 Dare I ask? o_O

    • Mr Data says:

      My shields have been shot from going there. *recharging them* though I ADMIT I like the climate section as it’s not over-ran by Obama bots.

    • Mr Data says:

      The only thing the forum is useful for is the solar activity where I can learn about what is happening with sunspots and the understanding of how they link to weather which sadly is absent on here.

  6. When the rain returns, if it’s below average for the remainder of may and for June, and we have a 2009 kind of summer, is fire danger likely to be higher or will this dry spell not affect that?

    • W7ENK says:

      There’s so much snow on the ground up in the mountains right now, I don’t think this dry spell will make one iota of difference… Now, if we were coming out of an El Niño winter that had paltry snow amounts, then I might be concerned.

  7. Mr Data says:

    So far I rate last Saturday the 4 and 1/2 star day. If the temps were just a few degrees cooler I’d go for a full 5 stars.

    Today we went to the viewpoint up at Silver Falls Park and the haze was so bad you could not see the coast ranges. Normally you can see Mary’s Peak towards the SW from the vista but today there was not the faintest trace of that mountain.

    I rate today the ugliest visibility so far since this warm spell started which I forgot when that was. I think early last week.

    • W7ENK says:

      You can thank the Pacific Ocean for the haze, all that moist marine air that pushed into the valley on Monday evening.

      I’ve never been up to the viewpoint, I’ve only hiked the trail down along the river. I really need to get back up there again soon, and this time go up to the viewpoint! Pretty nice view when it’s clear, I take it?

    • Mr Data says:

      Gorgeous! I thought the marine layer would be what KILLS the haze so if that doesn’t kill the haze what conditions do?

    • Mr Data says:

      Dad and I thought it was farmers burning down in Eugene since they don’t have such a strong ban limit unlike here in Marion County which our farmers hold off till August and then burn all at once making the skies VERY ugly.

    • W7ENK says:

      Light to moderate offshore flow, absent smoke from wildfires, or pretty much any flow with an Easterly component that keeps the marine air at bay, barring any humidity of course.

    • W7ENK says:

      I don’t think anyone is burning right now, it’s the beginning of the growing season. Unless anyone out there is still burning slash piles, but those are usually all done by now… but I don’t think any lingering slash burns would be of a large enough scale to obscure the whole valley? I could be wrong.

  9. Steve Pierce says:

    Thanks Mark. I already sent something out yesterday about this. Just kidding. 🙂

  10. W7ENK says:

    Hahaha! Press release… 😆

    Have a great time camping, Mark! If you’re headed to the Eastern side of the mountains, I saw lots of big cat tracks just about everywhere I went both weekends I was out, so take a gun and don’t let the kids wander off too far. 😕

  11. weathercrazy82 says:

    Completely clear here and down to 45 degrees. Now the sun is up and it looks like another great day!

  12. paulbeugene says:

    Actually the next one will be 2117. I would be 147 years old. My kids would be 119 and 117 years old.
    In the year 7541 Jupiter will pass in front of Saturn (as viewed from Earth), and will again that same year. It has not happened since 6856BC. By then there will a KPTV MarsWeather Blog.

    • W7ENK says:

      By then, Earth could be nothing more than a radioactive smoking ember, Mars strip-mined of all its iron, Ceres moved and terraformed into the largest farm (Certified Organic!) known to Man, most of Titan’s atmosphere siphoned off for fuel, and what’s left of we humans will probably be searching for the next planet to take advantage of…

  13. paulbeugene says:

    Already looking forward to June 5 Venus transit. None of us or even our children will be alive to see the next one. Will try to head to the Oregon coast to watch the sunset with Venus visible on solar disk to naked eye.
