I have typically used weatherunderground to get my weather and forecasts. I liked their old layout and such, not so fond of their new layout.
Anyway, at the moment, weatherunderground is showing 99.9 degrees with a heat index of 116.
For grins and giggles, I also opened the national weather service page to my zip. They are presently showing 95 with a heat index of 103.
The 4-5 degree variance can (I figure) be a result of the location where the temp was taken. Can the same be said for the 13 degree variance in heat index values? That just seems like a wide range.
I have been giving Intelecast a try, but I think they get their info from Weather Underground. I do know that the local radar picture from Weather underground is more reliable than the radar image from the weather channel's app. I have used the NOAA app a couple of times, but not enough to give any recommendations.
John, it can. It depends on where and how they measure the relative humidity. A lot of the small electronic humidity meters can be quite erratic. A good sling psychrometer (sp?) is not cheap and takes a while to learn to use correctly.

Good point Andy, thank you for the explanation.
Monty, the suggestion you made looks like a reasonable weather site which agrees more with the national weather service in terms of variance between actual temp and heat index. I will be trying the site out myself.
I really believe surface temps and conditions DO vary and fluctuate over an area, say a township (36 sq. miles). Rainfall damn sure does.
Here's a link I use a lot. It is limited to hourly observations at local airports, but it is straight forward data.
I rely upon Intellicast app on my phone and like Monte mentioned, it is the work of Weather Underground.

Absolutely. Our nearest "official" weather station is at an airport some 15 miles away, in a town that's nearly all asphalt. My own weather station https://www.wunderground.com/personal-weather-station/dashboard?ID=KVTSOUTH2 ), published on weattherground, is several hundred feet higher, and in a forested valley; we've seen temps 10 or more degrees cooler. On Weather Underground, scroll down to see "Nearby Weather Stations"; There you'll see variations all over the map.
Asking questions like yours means you'd have a blast with your own station. Get one! And publish on Weather Underground. This will get you started:

I have seen similar variations between the "official" station at the airport and a private station roughly one mile away but somewhat surrounded by trees and houses.

I have had one for several years, here is the link to mine on WU:
For some reason my rain gauge no longer works, it may be a loose wire.
I also send my data to another web site (EW3639), among other things it does a QC and compares my values against predicted values based on nearby stations: Terrasurv QC plots
Nice to have when I want to calibrate or check my edm's on a line between two pillars I built.

Have you physically checked the unit? Sometimes an ant or bug will get sucked down the hole and jam, lol. Gives you very erratic readings.
The rain gauge mechanism (if you've ever disassembled the station is dead simple; most are a two cup teeter-totter that increments a counter every time it tips. Most problems are easy to fix.
I did take it apart, the tilting cup seems to be ok. I sometimes have problems where gunk will stop up the small outlet at the bottom of the rain funnel, but I cleaned that.
I use a Davis Instruments model with a X-MDA-1 board to connect to a control-by-web X-320m. The X-320m is stuffed in a metal box along with some other connections on the pole. Kind of tight in there, I believe it is probably a loose wire, just need to get out there and check it. On the same pole I have an outdoor wireless access point, two cameras, and an ADS-B receiver, so the cables and connectors take up a lot of room. Here is what the X-320m looks like (less than 4" high), easy to get one of those cables pulled out when I put it back in the box.
Check out an app named MyRadar. It's become my favorite for checking current conditions.

that looks like a nice app.... it would be nice if they had a computer version for us Luddites who much prefer such things

Nice. What do you use the ADS-B for? See who's flying your plane without your permission? :grinning: You have the iPad app?
