Heavy Rain Returns Tonight

There is some good news and some bad news this evening.  The bad news is that heavy rain is moving back into the metro area this hour after a break for several hours.  The good news is that the heavy stuff should be done not too long after midnight.  I expect another 1.0 to 1.5″ at most.

Here’s where we are at PDX as of 9pm:

BMAC Rain Two Day Total

I don’t have the time to take a look at the past 10-20 years, but  I also don’t remember many instances in which we’ve seen almost 5 inches of rain in 3 days.

A discerning weather geek may notice PDX and Vancouver stick out with much higher rain totals today?  That’s because around 1pm a heavy line of showers sat right over PDX and Pearson Airpark.  .53″ in one hour at PDX!  That’s a juicy subtropical airmass for sure, which reminds me that we had another record high today.

BMAC December Heat

I think the biggest problem the rest of the week will be mudslides and landslides.  Soils are totally saturated and additional rain will only exacerbate the situation.

    Okay, it’s my turn to play Wishcaster Extraordinaire…

    HRRRRRrrRrrRRRrrrR-Arrr model shows heavy rain resumes over PDX around midnight. It also appears that the low center continues pushing toward Astoria — Grays Harbor?

    No one is forecasting wind…

    Surprise windstorm, anyone?? 😀

  2. 1.22″ yesterday, 0.94″ overnight here. Had a thundershower roll through about40 minutes ago. Early morning wake-up call!

    I have lived in Laurelhurst for 9 years and have seen some drastic weather but this takes the cake. 2006 was rough there with Sandy Blvd being routinely (and thankfully) plowed causing drifts I had to help my neighbors through. A shovel, and a very capable SUV allowed me to meet and help several of them. This year is reminding me of that. And what I’m grateful for. This is one of several reasons I love weather. Comeroderie. Thanks Mark and all for a happy connection.

    We sure don’t want an earthquake right about now

  7. MasterNate says:

    Winds were impressive with several gusts over 40. Highest gust 48 mph near Molalla.

  8. 00Z not as crazy as the 18Z but still gives us snow.
