In recent years the availability of maps and satellite imagery online in programs like +Google Maps made the location planning easier. The availability of fairly detailed weather forecasts days in advance through the National Weather Service made the choice of where to go in a region a little easier. Apps like +The Photographer's Ephemeris added lines to show the direction of the sun and moon at any time of day or night, so you could anticipate the exact sun rise and set time, general sunlight illumination during the "golden hour" before sunset and after sunrise, as well as anticipate the location of the moon.

Another handy feature of SkyFire is to compare forecasts for a list of favorite locations that you've saved, so you can decide between locations to drive to, in order to have the best odds of a nice sunset.
I've tested these features a number of times now, and they do well at predicting when there will or won't be sunset color. Weather forecasting is notoriously imprecise, so of course you can't predict the direction or extent of the color, but so far the correlation between the SkyFire forecast and the outcome is impressive.
Here's the sunset that actually occurred with the forecast shown to the right for August 2:

There is also a new location synchronization feature, which finally enabled me to sync my iPhone TPE with my Windows TPE. There was a procedure to do it before that I had not been able to complete. With this new method it was quick and simple.
If you don't already have TPE, here's a link that you can use to find it in the Apple iStore:

Crookneck Consulting also offers a Photo Transit app which enables you to anticipate what focal length you'll need to capture a certain field of view to get the shot that you want:

I'm also testing TPE 3.4, so I'll probably have some details on that for you shortly!
