A New View

I got this from Cliff Mass’s blog this morning (via Pappoose in Scappoose in the comments on the previous post).  Check out the difference the new radar (not operational yet) makes up on the Washingotn Coast.  There is a very juicy front offshore.  Here’s Portland’s radar view, partially blocked as always by the Coast Range: Notice the line of rain way out there appears quite weak.  Then check out the view from the new radar about two hours ago!  Wow…looks much more impressive doesn’t it?  Can’t wait for it to be operational during the upcoming winter.

Surface based convection west of Cascades looks unlikely unless the ULL can lift the CAP which is not entirely impossible, and looking south there are indications the CAP is eroding due to large scale ascent increasing.)

    SEVERE HAIL: 1 to 1.5″ Eugene to Roseburg, along central-southern Oregon Coast and offshore(VERY rare) 1.5 to 2″ central-southern Cascades

    Things are going according to plan based upon last night’s analysis.

  2. Rob "Wrath" S.E. Portland says:

    Bend is about to get rocked. 1.48″ hail marker, 100% severe hail.. Severe warning may be needed soon.

    • Rob "Wrath" S.E. Portland says:

      2.02″ hail core marker, 100% severe hail. Severe Thunderstorm Warning needed now.

  3. Rob "Wrath" S.E. Portland says:

    Big storm west-southwest of La Pine is close to severe….

    • Rob "Wrath" S.E. Portland says:

      New cells firing south of Eugene….

    • Rob "Wrath" S.E. Portland says:

      Trying to fire*

    • ThunderCloud - North Plains says:

      Hey Rob do you think these cells trying to fire up near Eugene, and the lightning offshore means we may actually be able to pull of some lighnting here?

    • DELXV says:

      The thunderstorm ended near Terrebonne in central Oregon sprinkling enough drain to wet the deck. Lightning now occuring near the north Sisters mountain.

    • Rob "Wrath" S.E. Portland says:

      Overnight storms still look very possible. I see no reason to chance any previous thinking and the NWS agrees with this.

  4. Rob "Wrath" S.E. Portland says:

    Very encouraging to see all the lightning offshore and also south of Roseburg…

  5. can someone send link to Marks lightning page please 🙂 thanks!

  6. DELXV says:

    Thunder and lightning Just NE of The Three Sisters Mtns in central Oregon

  7. Rob "Wrath" S.E. Portland says:

    I am seeing one thing unfortunately though that well, doesn’t bode extremely well for storms, especially anything severe drifting off the Cascades. WV Loop shows that the flow is having a difficult time backing to the SSE with mainly a southerly flow. Radar trends confirm this with storms moving N-NNE along the Cascades. As the ULL nears the flow should back to at least southerly due to the circulation around it, and there’s a chance even southeasterly, but yeah until it does so its hard to be overly confident. However as the ULL and increasing lift approaches we could see storms fire virtually anywhere thanks to the strong shear and elevated instability in place.
