richard mann Posted August 6, 2014 Report Share Posted August 6, 2014 You must have had an incredibly heavy downpour to generate those kinds of numbers! How much rain did you receive after the storm passed?Not as much as you would think since the storm started and stopped within 10 minutes. So I got .51" in that time with the really crazy stuff confined to about 3 minutes or so. I don't want to clutter the PNW thread with my stuff but here is a video if you want to watch it. Skip ahead to 2 min for the best part if you want. .. So, to what do you attribute the more noteworthy level of precip., in this short time .. Derrick. — I was looking at the somewhat odd direction that sub-tropical moisture generated recently, has been being directed: some further north than usual, some more northeast to where you are. This with also the more specific topography right there more close-in to where you are; .. these ideas along together with some different elements of what I study mainly, i.e. colder air's movement looked at together with more general distribution, more year-round. http://earthobservatory.nasa.gov/IOTD/view.php?id=3461&eocn=image&eoci=related_imagehttp://earthobservatory.nasa.gov/IOTD/view.php?id=4597 Quote --- Link to comment Share on other sites More sharing options...
Black Hole Posted August 6, 2014 Author Report Share Posted August 6, 2014 Although there was very heavy precip throughout the valley this seemed particularly heavy compared to anybody else. Looking at the weather service page where they noted various reports of rain and wind I had the second highest precip total and second highest wind gust in the area. So for the two together I had the highest combo. Anyway assuming it was as localized as I believe it was, I think the microburst was basically right overhead which is why it was so dramatic but not so once you got away from my area. I really have never seen anything comparable here so I assume it was quite rare. I will also add that the radar returns did not reflect the true rain rate. This was probably because of the very low cloud base which allowed precipitation growth nearly all the way to the ground. The strong winds were from a little downdraft cape that was present ahead of the line. Quote Link to comment Share on other sites More sharing options...

Phil Posted August 6, 2014 Report Share Posted August 6, 2014 Definitely a microburst. They're fascinating phenomenon, that's for sure...actually have been known to bring winds over 165mph. Official microburst wind record is 150mph, at AFB near Washington DC, occurring just a few minutes after Ronald Reagan landed there: http://www.erh.noaa.gov/cae/svrwx/downburst.htm They can be detected easily on vertical-integrated liquid scans too, so next time you see a storm around, look for high values. We've had some rough microbursts here in recent years too. The June 29th, 2012 Derecho was full of imbedded microbursts, one of which slammed me with a 127mph wind.

Black Hole Posted August 21, 2014 Author Report Share Posted August 21, 2014 I am at 2.71" for August which is way above normal. The weather service office is probably on average a little drier than me and they average .78" in August. So if we use it anyway that puts me at roughly 350% of normal. More light showers in the area today but we are expecting a good soaking Friday into Saturday with more rain possible next Monday night. I bet I have about 3-3.5" or so by months end. July was also above normal with 1.28" at my house, airport average .70". For the year I am at 15.42", the weather service averages 15.73" on the year. So With quite a bit of time left I could be well above normal there too. 1 Quote Link to comment Share on other sites More sharing options...

You have done pretty well for the year so far, and have received more precipitation (liquid equivalent or otherwise) than San Francisco had during the 2013-14 (July 1 - June 30) season as they only totaled 12.54". I am assuming that your total is for the calendar year from January 1 to the present. Quote Link to comment Share on other sites More sharing options...

Hopefully this means that a much better winter is ahead for the West in general, but that is certainly not a guarantee, as active summer patterns don't necessarily lead to more active winter patterns.

Well if nothing else it should help to raise water levels both here and downstream. I do think that an active monsoon resembles the older el nino patterns that often had wet winters to follow with an active STJ. So although its hard to say, I think odds favor a wetter winter for that reason...and because its been a while since we both have seen one.

Longtimer Dan the Weatherman Posted September 25, 2014 Longtimer Report Share Posted September 25, 2014 We'll see. The downside with a larger group is that new members tend not to post when all they see is "Seattle Weather".I don't think the Pacific Northwest subforum needs to be combined with any other subforum, since it is large enough to stand alone. I was thinking more of having the Mountain West and Desert SW in one subforum merged for example, and possibly other areas adjacent to one another in which one subforum is used much less than the other.

There are still some model runs today that are suggesting that an even colder storm (colder than this weekend's storm) may come in Wednesday or Thursday of next week with a snow level near 6,000 feet. Probably won't happen but if it does, it would be quite early and cold for this time of the year. Quote Link to comment Share on other sites More sharing options...
Black Hole Posted September 26, 2014 Author Report Share Posted September 26, 2014 Still waiting for the rest of the 00z guidance to come in to try and get a better feel for things. But GFS is getting slower and slower with the arrival of the heavier rain. It still comes, but if its to be believed, it might be Saturday evening before it arrives.

Black Hole Posted September 26, 2014 Author Report Share Posted September 26, 2014 As of right now I think we are looking first a mostly warm, windy, and sunny day tomorrow. Clouds will increase in the afternoon and it looks like thunderstorms will blow up in the evening, but will not be widespread. Good shear, instability, diffluence aloft, and increasing moisture make storms a good bet. Some may even be severe, but probably not for us. These showers will continue into Saturday morning. As the front negatively tilts (back away from us), looks like we get a few drier hours in. Later the front will push through with a 3-6 hour period of heavy rain I think. Probably .5-1" for most. Thoughts yourself? As for next week I do see what you are talking about but my attention has been elsewhere lol. I will look into that storm in greater detail after ECMWF/Canadian come out later.
