Back to Normal

SnapshotBusy fire season across the USA this year…running only slightly behind last year’s biggest ever! 
Big changes occuring this evening that threaten to bring "normal" Northwest summer weather back by midday tomorrow at the latest.  I’ll be right back…it’s 11:04pm and I have a weathercast…Now I’m back and it’s 11:12pm.
What’s left of the front sitting offshore all through the weekend finally moved through the area this afternoon.  It was followed by a good push of cooler marine air.  Of course that marine air has much lower dewpoints than the tropical airmass that was sitting over us for the last 3 days.  Twice this weekend I turned on the air conditioner (once in car and once in house), just because it felt too sweaty…not too warm.  So we’re all finised with that.  By the way the models nailed the drop in the dewpoint quite well.  They all showed a quick drop after 00z today (5pm).  Other than some leftover moisture in the morning, it appears that the developing Pacific High offshore will give us nice north and northwest wind all across the region the next few days.  That’s a great pattern for sunny/warmer weather inland with a minimum of low clouds.  The warmest days should be Wednesday and Thursday.
Interesting to note that the general pattern we’ve seen the last week or two will continue for the next week or so.  That would be a strong ridge just to our east and a trough offshore.  Models say the trough will edge closer again this weekend.  At this point it’s only deep enough and close enough for an increase in marine air.  I see no reason to put rain in the forecast.  But there’s no chance of a heatwave anytime in the next 7-10 days either.
A few interesting facts about this weekend that I noted.

1.  We only had .01" rainfall at PDX all weekend…oops.
2.  The baroclinic zone (frontal clouds/rain) were so close to Portland yesterday that it was a mostly cloudy day in Hillsboro but mostly sunny and much warmer out towards Troutdale.  Quite a variance for being so close to a front.
3.  Dewpoint topped out at 65 at PDX late this afternoon.
4.  Overnight low of 68 Sunday AM was NOT a record because we had that 74 last year on the 22nd! (same date).  What’s the chance?  But a very warm night eh?

That’s it…more tomorrow…Mark

    Great day today! Sad to say that i did not head out and enjoy it as i must admit i was finishing up the 7th and final Harry Potter book. Best yet in my opinion, anyways this next week as a whole looks great. I plan on camping next weekend on the east slopes of the cascades by a little lake we found a while ago that we enjoy fishing at.

    btw first night in a long time it got below 60!! it hit 59.4 this morning at 415am!!!!!!!!!!!!! woohooo below 60!!

  6. offroadjosh says:

    well, i was soaked.(the first time) so yeah it was a soaker. windy to when the front passed. i missed the news last night and the 5am weather so what did they say? i listned to the weather at 2am on some station and they said no more showers or anything. but didn’t get to here much due to a broken berry picker and it needing to get back picking asap. but that hot weather really did a number on the berries they were mushy which is very bad. they started to get better around 5am this morning. then i check on the pickers at 830am when i woke up, and they were much better, so the weather has gotten cooler and dryer.

  8. offroadjosh says:

    Good morning. I was rereading some post and there were several questions that have been answered.
    I checked out the PDO site somehow I missed it and it iwas actually cool it has every months worth of PDO info, It also told you what it is.
    I learned what a surface pressure analomy was also when I asked about Mark doing a cold snap I meant summer not winter and its in the 50s for the first time in a looooong time.

    Thank you for the update Mark. It feels so refreshing to lose this humidity. We deserve this.

    Thanks for the update Mark!!!! Was a lot nice the further E I went today. Spent the afternoon with the family at Bonneville Dam, and was pretty warm up there with partly to mostly cloudy skies.
