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:
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.
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.
