Saturday 8am: A Few Thunderstorms Today

If you’re like me and have some things lying around the yard that shouldn’t get wet?  A little Whiskey-Tango look on the property like I have right now?  Put them away…there are showers and thunderstorms moving from south to north up the Willamette Valley this morning and anyone west of the Cascades could have a shower.  Here’s a good link to radar:

For a much better view, and to see lightning strikes, go here:  then RADAR > INTERACTIVE MAP > turn off national radar and turn on LOCAL SUPER RES, turn on GLOBAL LIGHTNING.  Then you can move all over the map.

Here are the lightning strikes in northwest Oregon as of 8am:

I’ll be at work later today.  We have an 8pm show on KPDX-TV and the usual 10pm on KPTV.

    Check it! Convection firing around Eugene again (like last night) and heading north.

  2. Big John in Woodburn says:

    Lightning flash, east of woodburn.

    • AdamInAumsville says:

      Sure doesn’t look like much on radar, but it’s definitely producing some lightning.

  3. AdamInAumsville says:

    Believe or not, I think some elevated convection is trying to pop up right over me.

    • AdamInAumsville says:

      You can see this on infrared. It’s a small area of CU developing and moving straight from south to north. Not sure if it will amount to anything.

    • AdamInAumsville says:

      Looks like some development occurred. A couple of cloud to ground strikes in Clackamas County.

    Here’s a CYA statement for ya.
    “Note that they’re there. Don’t be shocked if something pops overnight.” Hahaah!

  5. weathercrazy82 says:

    Nice 21 degree drop in daytime highs today. I for one am loving this afternoon/evening. 73 right now, nice and calm. Great evening.

    • Timmy_Supercell (Hillsboro, OR) says:

      I would have loved this afternoon/evening if it was completed with one ingredient…. this something we were talking about… some time back…. hrmmm yeah


    • josh says:

      yeah it is currently 68 here and did not get over 70 here today nice fall like day to watch some football

  6. PeterB (1170' Bellevue) says:

    That convection thing sure didn’t pan out. Snow is only 3 months away. Went to les schwab to check on getting some studs+wheels for the 4wd. With cold PDO and El Neutrado, just want to be prepared

  7. Timmy_Supercell (Hillsboro, OR) says:

    Well.. I guess thats all she wrote!

  8. W7ENK says:

    It sure got awfully quiet in here…

    Don’t throw in the towel yet! Hahaah!

    Short term…Doppler radar showing weakening area showers from the central Oregon Cascades north-northwest through the northwest Oregon coast. This area of radar echoes is slowly moving northeast and we are getting some clearing over the southern and central interior valleys this afternoon. All lightning activity has ended over the area this morning. With the clearing in the southern/central valleys this afternoon…we will increase the afternoon heating…which will increase the instability and possibly see some thunderstorm development in that area this afternoon/evening. The thunderstorms will ride northwestward along the thetae ridge axis into northwest Oregon and southwest Washington late this afternoon/evening. Much of
    the region will remain capped today…except right along the central
    Oregon Cascade crest…so do not expect deep organized convection. Expect precipitation/thunder chances will decrease from southwest to northeast through this evening.

  10. W7ENK says:

    66 degrees at 3pm, we’ll be lucky to reach 70 today…

  11. W7ENK says:

    Bye bye, thunderstorms that never actually happened. We’ll try again next summer! 😦

  12. vernonia1 says:

    The heat wave may be over…..but the humidity is killer right now….87% Was not fun mowing the lawn LOL

  13. W7ENK says:

    The sun just broke out here in Milwaukie, total clearing to the south, 64 degrees.

    If you got it, that was it.
    If you didn’t, better luck next time.

    It’s over, folks!

  14. runrain says:

    Portland, Oregon: where thunderstorms and snow showers go to die…

  15. There was never a good chance for t-storms around PDX today. Just enough cloud and rain drops to spoil what could have been a nice 80 degree day 😦

  16. Sifton says:

    Hopefully the 60 seconds of the lightest sprinkles you could imagine (about 2hrs. ago) will be the last for another 30+ days says I to the great rain spirit in the sky!

  17. just had enough rain to wet the ground. well, “wet” is used loosely, as its drying i can see individual drops on the deck and cars. was hoping for some sun today. wanted to do some swimming before footballs on later. oh well.

  18. vernonia1 says:

    one long loud rumble about 6am…then rain….now 68 & rising.

  19. PeterB (1170' Bellevue) says:

    Following the 700 mb vert velocity on the 4km wrf-gfs shows the evolution of today’s convection. SE to NW band will translate NNE today. Eugene already done. SLE maybe couple hours of opportunity. PDX clears out by early afternoon. Band should be overhead here round suppertime. Given the weak showing thus far, not too excited. Perhaps as the band moves N some surface based action will pop up over S WA cascades to generate some cells which could persist over the lowlands. Probably don’t need any more LTG in the forests though

  20. Garron near Washington Square says:

    I’m a little concerned about all the pink on the interactive radar. Is that hail on the east side of the metro? Better bring in more than just a few lawn chairs and plants if that’s the case.

    • Garron near Washington Square says:

      That’s awesome!!!! Clearly not awake yet as I thought the “pink” red flag warning was part of the ensuing moisture band.

      Heading out the door to Las Vegas in a few hours, hope to shoot some good lightning pics back if we get ’em.

  21. pappoose in scappoose says:

    My favorite type of weather forecasting/watching…NOWCAST!! Hahaah!

    National Weather Service Portland or
    843 am PDT Sat Aug 18 2012

    Short term…Doppler radar showing storms moving over the forecast area from the central Oregon Cascades north-northwest through the southwest Washington coast. The storms are fairly weak at this point with a few lightning strikes…mainly over the central Oregon Cascades and the north Oregon coastal range. Will continue the Nowcast for these storms this morning. The thunderstorm development lines up well with the lower thetae found to the north as the midlevel thetae ridge remains over Douglas and Lane counties. Models suggest the thetae ridge axis will remain oriented in a southeast to northwest line as it slowly pivots northeastward across the area today. Models suggest it will clear our northeastern/eastern zones this evening. Expect what elevated convection develops today to follow the midlevel thetae ridge.

    • chiefWright (marquam) says:

      What is thetae ridge?

    • pappoose in scappoose says:

      Theta-e Ridge – an axis of relatively high values of equivalent potential temperature. Severe weather and excessive rainfall often occur near or just upstream from a theta-e ridge.

  22. cgavic says:

    South west wind (strong) and 51 up here. Marine clouds to our west in valley(?)

  23. W7ENK says:

    I would have loved to see this upper level moisture move in over the top of yesterday’s pushing 100 degree heat, could you imagine the explosive development??

  24. 6 AM thunder and a bit of rain, scrambling to get windows closed and seat cushions in. Not the way I like being woken up on a Saturday morning 😦

  25. W7ENK says:

    I haven’t seen/heard/felt anything yet here in Milwaukie, no lightning/thunder/rain at all, just what appears to be a solid marine deck. 😦

    • W7ENK says:

      Okay, so I just stepped out front to take a look up at the sky, and the first raindrop to fall in 30 days hits me square in the EYE! O_x

  26. I’m thinking this mornings round of convection is about over. Should be more later today though and tonight.
