Get Your Weather Station Online! (Please)

Weather Station 1

Do you own a home weather station?  Do you have an internet connection and/or a computer that’s usually on?  Then you should be sending your data out to “the world”!

The best way to do that is via CWOP

Citizens Weather Observing Program (CWOP) is the best route to go.  Once you get your weather station up and running, submit a registration to the CWOP website ( to get a station number and start sending data.  Richard Collander at NOAA is the Program Manager for CWOP and will get in contact with you once you register.  Richard’s email address is:

Once you start exporting data to CWOP, your data will become available on the NWS mesowest webpages that are used by many, many people to obtain meteorological data.  The mesowest webpage is at:

The mesowest webpage has a google map background, so it’s easy to roam anywhere in the US.

There are other ways to view the data on maps.  I have a few on my webpage in the “Observations” section.

Why CWOP instead of some other online network of weather stations?

Because this network feeds directly into MADIS which is the “master collection” of observations here in th USA.  For example a TV station like KPTV can pull up most of those stations to use on-air.  The other big network of weather stations (WeatherUnderground) does NOT do so.  As a result the meteorological community does not have easy and automatic access to that data.  If you only export to WxUnderground, please get a CWOP ID and export to that one as well.  My home weather station software easily exports to both.

Some newer weather stations/software don’t need a computer running either.  WeatherLink IP (Davis Instruments) has recently been updated to allow exporting of rainfall and peak gust data, that’s one way to avoid running a computer.

    Not a 24 hour total, but since the rain started this afternoon, we’ve received 1/4 in. of rain

  2. *BoringOregon* says:

    Here come’s the rain, amazing it was in the upper 60’s with clear and blue skies a couple of hrs ago. And now the rain is coming in crazy to hear about how the people lived through the tornado.

  3. JJ97222 says:

    I checked with my friend and client Greg Ward who works in OKC and he and his family are ok but his wife lost her two stabled horses in Moore. He said it was a huge storm.

  4. runrain says:

    We are so lucky to be living here. Why would anybody want to live anywhere else? All we have to complain about is some gray skies and rain and it only makes things greener. So lucky. Pray for the people in Oklahoma.

  5. W7ENK says:

    Some really nice convective-looking storms firing up off the coast about to move onshore, and I’ll be dipped Mark if your lightning maps aren’t offline… Really?!? C’mon, get with the program!!

  6. W7ENK says:

    Moore, Oklahoma is gone.


    • W7ENK says:

      TV met just quoted as saying: “This is quite possibly the most destructive tornado in the history of the world.”. He said it with a straight face. Seeing the video, I’m inclined to believe him.

      Live stream:

      It literally looks like a nuke went off. The houses are completely missing from their foundations, there’s stuff on fire, everything not firmly anchored to the ground is just gone…

      Every time they show the tornado, I just know that I’m witnessing death… One live reporter broke down into tears, witnessed rescuers removing bodies from what used to be a 7-11.

      I don’t even want to think of the death toll from this. Today could likely become the deadliest tornado day in history.

    • gidrons says:

      That’s one record that I hope never gets broken. There was a tornado in the 20’s that lasted over 3 hours and killed hundreds.

    • gidrons says:

      2 dozen kids missing just from one elementary school

    • Lurkyloo says:

      Oh, wow. Damn.

    • Lurkyloo says:

      😦 😦 ;(

    • Sapo says:

      Yeah, the whole city is just gone…Horrible

  7. *BoringOregon* says:

    Wow amazing tornado in Oklahoma !!!

    • gidrons says:

      Horrific is a better word. Preliminary reports are that an EF-4 mile wide tornado took out an elementary school among other things. I’m done complaining about our showery weather.

    • Rookie says:

      Looks very bad.

    • *BoringOregon* says:

      I heard a 2mile wide just to bad 😦

    All the TV weather guys are sticking with a dry Memorial Day weekend I hope it will be we will need a break from this cold wet week we have coming. Tomorrow we will have to turn up the heat in the house. Need 80s but their not coming this weekend dry weather would be better than nothing.

    Classic Memorial Weekend Upper Low (MWUL) on tap. Some couscous sized hail and brief claps of thunder will be the most excitement. Not looking like any 80s any time soon.

    Looking forward to 90s-100s in mid-late July. Would like to have another year of temp extremes (in 1972 Eugene had what was then the all time high temp of 106, then proceeded to set what was then (and still is) the all time low of -12F, all in the same year)

    • My preference would be for an “average” June with only a few sub-70 days at PDX and a few days in the 80s as well, and slightly wetter than average (let’s say by about 40-50%) so that things don’t get too “droughty” and flammable this summer. Then somehow find a way for July and August to be slightly above average west of the Cascades but NOT above average in The Dalles. You know, ample heat for gardens on the west side without it getting miserably hot on the east side. Not a very realistic wish I’m aware, but it would be really nice.

      Then a nice early fall chill in early to mid September, followed by a 1952-style Indian Summer with almost every day between Sep. 20 and Oct. 20 in the 70s and 80s!

    • gidrons says:

      The May Upper Level Lows persist through the end of the month. At least eastern Oregon is getting some much needed moisture.

  12. JJ97222 says:

    Just went to go mow the yard and noticed the weeds are a popping out all over after a good week of rain, they are loving it. Have to go buy some more round up for tomorrows sunshine!

  13. JJ97222 says:

    KEX weather is Already forecasting rain and cold weather for the up coming 3 day weekend I heard just it a few minutes ago. They are saying this weeks cold and rain spell will linger thru the holiday and they actually timed it with beginning of Rose Festival. Still time to get Plane tickets and head to the sun!

  14. Since when did the NWS get involved with the mortgage crisis?! 🙂

  17. runrain says:

    8 straight hours of rain here in Happy Valley. Looking forward to cool but dry for the race tomorrow.

  18. JJ97222 says:

    All of the TV 7 day trends are calling for rain next Saturday except Mark’s, looks like another indoor sport 3 day coming! Lets hope Mark is on the dry bias and it carries thru to be true.

    • Sifton says:

      30 more days till the last train to S.A. leaves right??

    • JJ97222 says:

      Actually 27 almost all packed up the movers will be on the 14th June so it is crunch time. We have 5 going away parties to attend in the coming days hopefully the Rose Festival Low will subside to get some outdoor beer drinking and barbecuing in before we leave. San Antonio weather looks great 90 and sunshine for Memorial Day weekend. Just got the pool down there changed over to a salt water system so it will be ready for the kids.

    • Jesse-Stevenson says:

      You won’t be missed!

      Sorry to say JJ97222 will gone soon but will reappear as JJ78259 sometime in the near future!!!!!

    • Sifton says:

      But of course, I can’t wait to hear weather updates from 2,000 miles away!!

  19. JJ97222 says:

    Sounds like this mid week storm could be a little like late October cooool

  20. Jeff Raetz says:

    My parents in happy valley have one that has been going for awhile. Fox12 weather maps for happy valley are stats from my parents! Thank you Mark Nelsen

  21. JJ97222 says:

    Moderate rain under the dome right now. Making up for lost rain!

  22. Memorial Weekend Forecast: At this point there is no reason to believe it will be nice any one day. Plan for the weather we have been having the last couple of days. Showers, cool temps, maybe a few sunbreaks. Temps in the upper 50s and low 60s.

    • JJ97222 says:

      Right on the money when I was building my Storage shed in 2008 we had the set up cold rain during the week before Memorial Day. Had the dump box out front for the debris removal of the old shed all the weather guys were in agreement the clear nice weather should start Friday before the three day weekend. It rained Friday and most of Saturday cloudy and dry on Sunday rain on the holiday needless to say it was a soaking cold experience. So yes not much has changed.

  23. What I’d like to see are more weather stations with *accurate anemometers* set up in the eastern Gorge. Reason? We know that the reason Crown Point gets so extremely windy in the winter is because of topography – and it’s considerably windier than other sites a mile or two away. If there’s a “sweet spot” for especially strong winter east wind, there could also be one at the east end of the Gorge for west wind in spring and summer. It’s already been established that Maryhill tends to get slightly stronger peak gusts than The Dalles does. Could there be an even better location for even stronger wind?

    I would enjoy nothing more than to experience a 60+ mph gust on a mild and sunny day in June or July!

    • Mark Nelsen says:

      The windiest locations do have anemometers, but it is behind a paid site…iWindsurf.

      I used to work for the company (Micro-Forecasts) that installed and then sold the sites to iWindsurf sometime in the late 1990s maybe? They are far windier than DLS.

      Locations are Stevenson, Swell City (near the fish hatchery on the Washington side), HR Event Site, Rowena, Doug’s Beach, and Arlington.

    • Which of those sites do you think is the windiest? My bets would be on Doug Beach since it’s along a straight stretch of the Gorge.

      Another possible candidate for extremely strong wind gusts might be a few miles east of Maryhill at the top of the Goodnoe Hills. You know, those really steep hills north of John Day Dam that actually have a few *junipers* growing on them?

  25. Greg Carstens says:

    I wish I could simply afford to do this Mark. I have no idea when I will be able to. Just when I catch up on the bills I have another pile that rear their ugly head. I would love to be on CWOP since NWS Seattle has denied me three times to run an NWS COOP station up here in Southeast Tacoma. I have equipment for it but they are still not interested and have used the excuse that they don’t have the funding to set something up here. Funding for what??? I have bought all my own equipment and download the B-91 record of climatological observations right off the NOAA website link. Go figure huh? I would also love to try and earn some of those COOP awards that I see that go out to other COOP observers across the country.

  26. Mark Nelsen says:

    And to support my continuing belief there just can’t be too many online weather stations in the Corbett area…a new one this week about 1/4 mile west of Women’s Forum viewpoint.

    Nice solar radiation sensor! I’m way too frugal to install one of those.
