Finding min HIGHs & max LOWs (climate, recorded, temperature, day)

[CosmicWizard]

Using wunderground, I can find the High & Low temperature record for a specific day of the year. EG: for Grand Junction Colorado, the High temp record for July 31 is: 102 and the Low temp record is: 58

Does anyone know how to find is the lowest High temp and the highest Low temp for July 31 in Grand Junction, CO for example.

I don't know of a way to do that. If you find out, let me know! When you have a record low maximum or a record high minimum, the NWS climatology pages will let you know, but I don't think there is a readily available listing for what they are day by day.

I work for the NWS....and the best thing out there avbl to the general public is xmacis program with data powered by University of Nebraska Lincoln. It is not the most user friendly system out there. You can also call the National Climatic Data Center in Asheville NC directly (do a web search) the data they send you can be easier to read but costs $$.

Anyway I included the link below from Grand Juction NWS (ID GJT). You can look at data kept for other locations by using http://xmacis.unl.edu (broken link) and then using the left menu to search for your nearby NWS office 3 letter ID.

http://xmacis.unl.edu/GJT/ (broken link)

Now...on the left....under routine click on calendar day extremes. For station...default is the local office area....but you can choose stations for which data may be avbl by clicking on down arrow. For variable...select max or min temperature. Keep the start and end year the same as what pops up....it would include the historical climate period of the station. For High/Low...click on lowest values when searching for max temps and highest values when searching for min temps. The result will show up on the right....it will list month on top and day on the left and the corresponding temperature (lowest high temps or highest low temps). Now, the program will not give the year....this is an issue which has been brought up by our NWS office and is hoped will be included in future updates.

Clear as mud? Hope it helps some.

You can contact your local NWS office Organization - NOAA's National Weather Service

or the NCDC at NCDC: * National Climatic Data Center (NCDC) *

Thanks again for taking the time to post the actual temps. Too bad the forum software doesn't allow pasting an Excel object as formatted in Excel . It would be a nice feature to have the data structured in a table format.

Western U.S. Climate Historical Summaries

Try this link. It has info from tons of weather stations across the western U.S. It's slow with the updates, but as long as you keep track of new weather records, it shouldn't be a problem.

GRAND JUNCTION WALKER, COLORADO - Climate Summary

Here's the link to the Grand Junction station. Just scroll down the left side, click "daily summary stats", then everything's there for you. The information is a bit hard to read, but you should be able to figure it out.

This is a very useful website, imo. It is only for the western U.S., but for me, that's not a problem.

[CosmicWizard]

Thanks Bob!

I came across this website once before and even printed out some Grand Junction data, but I couldn't remember the url. My daughter worked for the Desert Research Institute ( DRI ) as a Geology grad student at the University of Nevada. She gave me a tour of the DRI facility during one of my visits to Reno. It is a fabulous facility and a great organization.

Thanks again....Franco
