To be pedantic, and I am, The Weather Channel was purchased by IBM, who wanted (no, not Weather Forecasts) access to their ultra-high volume web transaction technology.

WRT the original poster, I use the Dark Sky app. I believe it's powered by Forecast.io.

If you use Ride With GPS, Strava, or Map My Ride, an iPhone app called Epic Ride Weather allows you to identify a saved route, the start and stop time for your ride and it will give you the weather and wind you can expect along the route. It uses the Dark Sky/forecast.io data for the forecast.

If Weather Channel would stop spreading their resources out across 5+ different apps (and website domains) under different subsidiary monikers-they could make something amazing....which I think is what they're moving towards.


Accuweather is the only other commercial weather domain I can name offhand that isn't owned/operated by The Weather Company.

Word on The Weather Channel.
I've been using Wunderground for years but lately, for unknown reasons, they've been missing the mark. Are the patterns changing and they haven't changed the prediction models? I don't know, but they've been off at least twice a week with forecast temps and rain - it rained on two days where they predicted none. Fine, it was drizzle that didn't show up on the radar, but it was a cold, miserable 45-degree drizzle.

Accuweather's not much better either, unfortunately. I've started looking at NWS forecasts, but they're not as detailed.

I do the same, mainly with our local NBC affiliate. If there's rain in the forecast for the next day, I always watch the 6 and 10 PM newscast with their "Futurecast" to see if it might be raining in the 6 AM and 5 PM hour when I'm most likely to be riding. If it looks like there will be a break in the rain, then I'll usually go ahead and ride to work. If I wake up at 5 AM and it's pouring with no end in sight, then I'll just drive.

If you can read a graph (not everyone can, unfortunately), the local forecast (use your zip code) followed by the hourly weather forecast down at the bottom right is pretty good for most things: precipitation probability, precipitation amount, wind and wind gusts, etc.

That's pretty cool. Wish Google Maps would do something like this for drives

Hey, that's sweet

Very cool indeed. Downloaded and installed and linked to my Strava account. It will prove very useful. Thanks. :thumb:

A few years back, a local radio station had what they called "Ginger the weather dog". The concept was pretty simple - in the morning the owner would offer the dog the opportunity to spend the day indoors or outdoors. If the dog elected to spend the day indoors, they took that to mean rain, otherwise they took it to mean that it would not rain.
Yeah, it was silly. But surprisingly accurate. Better than some of the other human forecasters that were on TV.

Awesome find! Thanks for this. I used it today.

Weather Underground. I never found AccuWeather, WeatherBug or Weather Channel to be accurate. Waeather underground has been pretty accurate and their app is fantastic for forecasting rides.

This seems really cool but I'm struggling to get it to work with mapmyride. Seems clunky.

I've only used it with Ride with GPS, sorry.

PatrickGSR94 05-19-17 08:24 AM

Yeah and it's also $3.99 every six months apparently. I'll just stick to TWC app and watching the local forecast.

Hmm, topographically that page is a twig at the end of a branch at the end of a ...


Best bet is probably to click on the NWS logo at the top right, search for your location, then click on the hourly forecast graph down near the bottom of the page.

OR, the numbers in the URL are the coordinates

Thanks guys. That wasn't all that hard, but it wasn't intuitive. This page does have a lot of information, and that's great. The only deficiency with forecasts and observations that troubles me is with the wind direction and speed. Along the river edge of the island, the wind is shifty and gusty, so I suppose any observation doesn't make a good generalization of what I'll experience.

Weather Underground is very good for me. The Android app is very good and straightforward and easy to see at a glance. Also I have a personal station in their network so I can see conditions at my house immediately.

I use the RadarScope app for near term and day of ride weather and Accuweather app for the daily and weekly forecasts. Radarscope lets see you where the rain clouds are right now and what is coming. They have a pro version that shows lightning too but it's unnecessary in Puget Sound area.

You need to dig deeper on site/app. NWS has all the detail you could ever want in the short/long range discussions, although it takes a while to get a handle on the shorthand lingo they often use. You practically need to be a junior meteorologist :) I use their iPhone app, a little dated in look/feel, but has plenty of detail for my needs in the layman's detailed forecasts.

NWS / NOAA has been paying attention to some comments. Here's the New! Improved! point forecast page for Central Park in New York City:

https://forecast-v3.weather.gov/point/40.7673,-73.9823

There are at least three ways to change the location:
  • Toward the upper left corner of the page, enter the location or ZIP code you'd like to see.
  • Dragon drop / recenter the map that's halfway down on the right side of the page.
  • Courageously, edit the latitude and longitude in the URL, remembering that west longitude is entered as a negative number.

If you read the bumph about the changes, most of 'em are plumbing behind the scenes.

One new feature that's visible: below the graphic daily thumbnails, there's now a new tab on the left side of the page for hourly forecasts.

The only glitch I've encountered so far: sometimes, the "Current Conditions" are highlighted as not being current observations. The same thing happened (rarely) with the old format, but with the new format, it seems more frequent. That could be random bad luck. It doesn't affect the forecasts.
