More Warm Weather

SnapshotIt would have been nice to break the record today after sweating out in the garden this morning, but at least we did restart the 90 degree counter for this season…it was Day #1.   A minor marine push  has occurred over the last few hours which means a cooler day tomorrow.  The upper-level ridge isn’t budging much through the weekend, so no big cooling trend for now.  These "northwesterly" pushes often don’t get much cloud cover into the interior in the mornings, so still mostly sunny skies the next 3 days.  We stay mild Friday, but then Saturday an approaching strong trough allows the ridge to strengthen ahead of it.  That pulls the warm air back to the west, so we should be back in the 85-90 degree range then.  One change in the 00z models is a slowing of the progression of the trough inland.  It probably won’t move in until Monday, so Sunday should still be quite warm.  With straight southerly upper-level flow both Saturday and Sunday, we’ll have to be on the watch for possible storms over or even west of the Cascades.  Then a strong marine push and weak front drop temps about 20 degrees for Monday.  So enjoy 4 more days of summer, then it’s back to May-like weather next week…Mark

    Rob, what’s the latest?

    Hmmmm SPC sounding analysis for SLE(Salem) shows some CAPE now as well as LI 0 edging towards -negative. Even more impressive is the sounding for MFR(Medford) CAPE 1,462 and LI -5.

    Rob, nice link. It was a pretty good show. I am wondering if any fires have started tonight due to the lighting in our area…

    Alright the storms pushed through on the cam, but I saw many many flashes and bolts… Kinda neat. I hope someone checked out the link and saw the light show as well.

    Hey if anyone is bored there’s a line of severe t-storms blasting through the Lubbock, Texas are.
    This is the link to live cam pretty constant lightning
    Enjoy 🙂

    Thoughts about tomorrow?? COuld be interesting.

    Rob, with the sun up surface based CAPE in NW OR is 1000j/kg, 2000j/kg in SW OR. Definitely some decent surface parameters down there with decent low level lapsed rates (good indication of severe hail) and decent surface based (1000 to 500mb) lifted index. But I’d imagine that the sun is the main trigger here. Flow seems to be SSW over the Cascades and WNW in the I-5 corridor, so whatever does stay alive should be well off to our east. Still hoping for a distant lightshow though, I’ve got a great view of the foothills from my house, so I often see overnight thunderstorms that affect the Cascades.

    Yeah AM radio works perfectly and has gotten quite a work out this afternoon-evening. AM radio detects all lightning discharges, where as lightning detection software can only detect cloud to ground strikes.

  10. AtmosphericWrath -Far S.E. Portland- says:

    Oh the VIL reading (Vertically Integrated Liquid) The higher that # the better potential for larger hail. I know for a time that severe warned cell was indicating VIL 60>. You can use Wunderground Radar, but I recommend GRLevel3 it’s far superior.

  11. Mback says:

    It has been quiet awhile. So how can you tell what size hail these storms are producing and how does the whole AM Radio trick work?

  12. AtmosphericWrath -Far S.E. Portland- says:

    Derek, if you’re on Yahoo Messenger send me a message and I’ll try best I can to help you with that problem.

  13. AtmosphericWrath -Far S.E. Portland- says:

    Oh jeez sorry I just noticed Lol Hey Mback buddy. It’s been quite awhile hasn’t it. Feel free to post.

    I have tried spybot and norton and neither of them do anything. It sucks. Nice storms though, you can see them to the SE from here easily.
