Ive had rain alarm on my PC for several years. iPhone app is great too. Its something I count on and look to everyday. You can set it to the radius distance surrounding the area wherever you go. The push notifications will let you know in advance if you are out in your nice sporty car and/or motorcycle/bike. You can decide from there if its a simple little passing rain cloud or major storm in the vicinity. Then you can decide if you should wait it out / take cover and/or leave the area altogether.
Love it !!!!!!!
