For some of you/us, it’s been raining almost constantly for over 80 hours, since midday Sunday.
That’s just about anyone from Battle Ground down to Washougal to Troutdale and into the foothills of the Cascades. That includes my home out in Corbett where I’m up to around 5.50″ of rain. One would think it would produce flooding, but it’s just been a light-moderate rain the whole time…EVERY hour, EVERY day, for day after agonizing day!…sorry, distracted a bit there.
For comparison, I see Hillsboro and most of west metro area has only seen .25-.50″. This is an extreme example of orographic lift, where moisture pushes up against the mountains (for 3 days!) and has to drop its load of rain on the windward slopes. The west side of the metro area was in the lee of the Coast Range, thus quite a bit of a rain shadow there.
The flow of moisture shifts north on Thursday so the rain should finally cutoff in even the wet areas. As mentioned yesterday evening it appears we get some mild weather Friday through early next week.
Long range models show cool troughing the middle of next week with snow levels somewhere below 2,000′ again. Then ridging again afterwards as we head towards the middle of February. I always like February because it seems to pass by quickly compared to January, I suppose 2-3 fewer days in the month helps; maybe it’s the anticipation of Spring right around the corner too.
Here is the 00z GFS ensemble chart:
You can see the cool dip later next week and then a little warmer temps beyond. Note a few of the ensemble members probably have the 2nd ridge a bit farther offshore, thus putting us into cooler high pressure with a cold north-central USA trough a bit closer. The 12z run showed that, or was it the 18z? I forget.
As for the comments…sigh…there was some very brief drama earlier today in the comments. Luckily it didn’t turn into a big blowup as it did a year or so ago. Yes, it’s been that long. It was unrelated to anything that occurred here. I didn’t want to deal with that stupid behavior; it sounded like middle school kids arguing, so I just shut off the comments for the rest of the afternoon/evening. I’m much busier with more shows and responsibilities nowadays and don’t have time for that crap anymore. I don’t care what happened elsewhere and I don’t want it to spill over into this forum.
So this is how it goes:
1. Comments are back on
2. NO mention of any issues from any other group or forum.
3. If you bring it up or participate in an argument, you’re on moderation for at least the next two weeks.
4. If you don’t like something someone says about you I strongly suggest you don’t get into an argument about it.
