When I hear you talk about the statistics and science of weather I feel I am being educated and respected and I am appreciative.<br /><br />When you actively take exception and contradict the dominant usage of subjective terms like good and bad in reference to weather it smacks of pettiness and you become less respected in this community. Everyone here certainly knows by now what your preferences are and I'm sure we can respect that while still applying terms as they are most commonly used. Yes, we understand that you prefer cooler, cloudier weather and consider temperate summer conditions not to be weather at all. You are not under attack by our language though you may feel so. It is simply common usage. <br /><br />I strongly encourage you to write your own blog that is specifically for people who share your preferences. I wouldn't ask you to leave this discussion, which is not my right anyway, any more than it is yours to "correct" MY perceptions. I am asking you to let go of conflict and truly contribute your very best which I AM seeing more of lately and I do appreciate it. <br /><br />I am truly sorry to have responded in a reactionary and negative manner in the past. I am here to learn. <br /><br />Yours Truly;<br /><br />Natchrl8rAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-1891180523296771802009-07-27T11:23:09.420-07:002009-07-27T11:23:09.420-07:00I think the confusion lies here:

However, these <i>do not occur at the same time of day</i>.<br /><br />In other words, as "Weather is my life" said, it's exceptionally rare to have temperatures at or above 90°F and RH values at or above 90% <b>at the same time</b>. <br /><br />In the morning, the low can be 80°F with a dewpoint in the upper 70s, giving RH values above 90%. But by the afternoon when the temperatures are above 90°F, the dewpoint is still in the upper 70s, yielding much lower RH values.<br /><br />This is why, in my opinion, we should not talk about RH when discussing how "humid" it feels... it just confuses the issue.<br /><br /><br /><br />Anyway, it's gonna be a hot stretch ahead of us. For Portland, I'm guessing we'll see the following Mon-Wed highs:<br />100°F, 103°F, 104°F<br /><br />Combined with dewpoints in the mid 60s, this will make for some disgustingly hot weather, especially for people like me without AC.Michael Gosshttps://www.blogger.com/profile/01829847179425933623noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-10617977545400089322009-07-27T11:07:36.871-07:002009-07-27T11:07:36.871-07:00It stayed warm all night.

It was 86 at 9 then dropped to 81 around Kalama, then 76 by Longview. Dropped to 74 at 10 by Castle Rock, then rose to 79 going up the south slope of the Toutle Hill, then 73 by Centralia and back up to 75 at 11pm by the time I arrived home.mainstreeterhttps://www.blogger.com/profile/06311958194036737432noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-84812310344054551372009-07-27T10:47:03.579-07:002009-07-27T10:47:03.579-07:00Thanks for the info about dew points, Weather.

There's nothing contrary about that. In the case of this week, I agree with everyone that it's not good weather. When it's sunny and 70 outside, I still don't like it. You obviously don't understand. Nice weather for me is cloudy, or if it has to be sunny, at least be under 50 or 60 degrees. I'm not contradicting anything. And unfortunately you can't use a subjective term and expect everyone to know what you're talking about or to agree with you.Weather Is My Lifehttps://www.blogger.com/profile/11959087601911808613noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-41306971937929974772009-07-27T10:19:35.093-07:002009-07-27T10:19:35.093-07:00lol kyano, I know you said it was in DC.

LOL)<br /><br />However, I'm sure they spent some time making sure that all the maintenance was done and that everything that they can bring online to deal with the spikes in demand is ready to go.<br /><br />Remember these strategies to help the utilities, your neighbors, and yourself during this weather:<br />- do anything requiring electricity and water at night, if possible -- laundry, dishwashing, and so on<br />- only run your A/C when you're home or turn it up to 80 when you're away<br />- turn your A/C up a couple of degrees... even 75 will feel lovely compared to outside<br />- use ceiling fans and regular fans even if you have A/C. A fan in the room you're in will make it feel 4-6 degrees cooler than the actual temperature<br />- make sandwiches or other "cold" meals so you don't have to heat up your kitchen, or go out to eat<br />- skip cutting the grass this week (and using any other gas-powered outdoor appliance) -- pollution will get really bad and there's a real risk of fire from any spark<br />- don't let kids (or anyone else!) open or play in water from an open fire hydrant. Call 911 and report the open hydrant. Even a few open hydrants can dramatically reduce the water pressure available to fight fires, and they use phenomenal amounts of water, too. Put a sprinkler on your hose for the kids if you must, but consider going to an actual water park instead (Crossroads, anyone?!)<br />- Check on your elderly or otherwise frail neighbors. Make sure they have fans, enough water, and so on. If they don't, consider calling local social services or the police non-emergency number to get them help. I bet the counties will open "cooling centers" this week -- community centers and other public spaces where people are welcome to come cool off.<br /><br />Hope these ideas help.JewelyaZhttps://www.blogger.com/profile/09434569437851248356noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-18303613724052357412009-07-27T00:25:49.108-07:002009-07-27T00:25:49.108-07:00@Weather is my life: you can't have it both wa...@Weather is my life: you can't have it both ways. You complain bitterly whenever we have nice weather here -- sunny skies with moderate temperatures. Now you're saying you don't like this weather? Being a contrarian is a pain sometimes, isn't it, getting caught up in the double- and triple-negatives.<br /><br />I know how to use a dewpoint calculator. I am not ignorant. Yes, it takes a LOT of moisture to make such high humidities in high temps. However, it does happen.<br /><br />Going in and out of A/C (~68 degrees, very low humidity) when the weather is in the 90s with high humidity makes many people develop sinus issues. It's not a matter of "catching a cold" -- that's a virus and it has nothing to do with weather -- and everything to do with torturing your mucus membranes.<br /><br />By the way, the east and south are considered humid subtropical climates. http://en.wikipedia.org/wiki/Humid_subtropical_climate#North_America<br /><br />I'm done talking to you about this subject. The weather in NC is not what you know best and it doesn't have much to do with the weather we're about to experience, though it will feel familiar to many of us who have escaped the hot and humid southland!!JewelyaZhttps://www.blogger.com/profile/09434569437851248356noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-59683078796115732082009-07-27T00:18:11.115-07:002009-07-27T00:18:11.115-07:00Weather is my Life - I grew up in DC and I certain...Weather is my Life - I grew up in DC and I certainly remember lots of days in our summers where it was 95 degrees and 95% humidity, and we didn't have AC either.

Do you realize that for Wednesday morning, the probcast is forecasting a low three degrees higher than the highest low temperature ever recorded in Seattle?? The record is 68, and the Probcast says 71, as low as 67 and as high as 75 for the low. The WRF-MM5 low temps Wednesday and Thursday morning look to be in the low to mid 70s as well. I'll be very curious what it says for the high for Wednesday - how close will it come to forecasting a record maximum temperature all-time for Seattle (which currently stands at 100)? Just the fact that it has a chance of as high as 101 on Tuesday is amazing.Nickhttps://www.blogger.com/profile/14096215378082506457noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-39238836293407955462009-07-26T23:32:23.816-07:002009-07-26T23:32:23.816-07:00Jewelz,
Take Cliff's class. Then you'll ...Jewelz,<br /><br />Take Cliff's class. Then you'll see my facts are not wrong. Or just search online for a dewpoint calculator. There's really no need to learn the derivation of the equations, or even the equations themselves, just search for that. With a temperature of 90 degrees, it takes an awful lot of moisture to create a relative humidity of 90%. If the temperature is higher than 90, then you need even more than that.<br /><br />If you're interested, the relative humidity of the air is equal to the mixing ratio of the air - related to the dewpoint - divided by the saturation mixing ration of the air - related to the temperature. The mixing ratio of the air is equal to 0.622 * (partial pressure of the water vapor) / (air pressure - partial pressure of the water vapor). The saturation mixing ratio is equal to 6.122 * e ^ ((17.67 * air temperature)/(air temperature + 243.5)), where the air temperature is in degrees Celcius, and the saturation mixing ratio is in millibars. You can use that, but you probably don't care to, I'm guessing. You could just search for dewpoint or relative humidity calculator online. Then search for highest dewpoints recorded in the east. 87 is just very rare. It is a fact. Learn about it before you state that it is wrong.<br /><br />They might have relative humidities at 90% or higher at night, but they don't have 90 degree temperatures at the same time.<br /><br />And no, Jewelz, I don't like horrible weather. I like good weather. I like nice weather. Why would I ever call something that I like horrible?<br /><br />And going back and forth from A/C to not A/C does not get you sick.Weather Is My Lifehttps://www.blogger.com/profile/11959087601911808613noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-60263076024632583902009-07-26T23:23:38.754-07:002009-07-26T23:23:38.754-07:00What's really scary is the possibility of blac...What's really scary is the possibility of blackouts due to constantly running ACs all over the Puget Sound.

And I lived there for many years without air conditioning. So I paid CLOSE attention to the weather, both temps AND humidities.<br /><br />In Durham, NC, there were at least three weeks' worth of days that were 90F+ and 90% or greater humidity. They almost always brought spectacular evening thunderstorms, which brought a few hours of relief, sometimes, to those of us without AC... but often greater agony for those with it, because the power would go out and they would actually get hot. LOL<br /><br />It is not at all uncommon for the summer overnight temps to stay in the 80s and for the humidity to stay above 80% as well. A "nice" night in Raleigh features a breeze and temps that cool into the 70s.<br /><br />Raleigh's weather this week is really typical; highs above 90 each day and lows around 72 each night. Thunderstorms are called for each afternoon by the current forecast.<br /><br />At the moment (2 am), Raleigh's temp is 78F, humidity is 79% and the dewpoint is 69F.<br /><br />Anyway, anyone who has lived in the Carolinas, Florida, Georgia, Mississippi, or Alabama is going to call BS on your "facts" here.<br /><br />Oh, and the majority of poor people across the south DON'T have air conditioning. It costs about a dollar an hour to run and that's $300 a month that a lot of folks just don't have. I didn't when I was living there.<br /><br />I LOVE living without A/C. You still have to go outside and running A/C in a car all the time is very expensive especially with higher gas prices. And going from A/C house outside to hot then A/C car, outside again to A/C office and back multiple times a day is a great way to get sick. <br /><br />Hey, but you LOVE horrible weather, right?

I would come in from playing and be physically ill day after day, finally concluding I could do little outside till after 7 pm. Here it's painful renting, not having shade trees, poor insulation. We now have a couple of window AC units. In the South, we had central air after years of no AC. Lifesaver. But I remember spending some summers in Virginia Beach with family, and it would get up to about 100 degrees with high humidity. Wretched: and then the AC broke. Now, that was misery. If humidity doesn't get that high this week, we'll make it. I don't want to go through the VA Beach nightmare ever again.Picnicking in Dreamlandhttps://www.blogger.com/profile/02699941865912536834noreply@blogger.com
