How can I check whether it will rain before leaving home?

Search for your location on WeatherPerch and review both the current conditions and hourly forecast. The precipitation percentage gives an indication of the likelihood of rain during a specified period, while the hourly forecast can show how that likelihood changes throughout the day. Radar can also provide useful visual context about current precipitation activity. If rain would significantly affect your plans, avoid relying on one number alone. Look at precipitation probability, hourly conditions, radar, and relevant weather alerts together. Rechecking shortly before you leave can also be worthwhile because forecasts can be updated. This approach can help you decide whether to carry rain gear, change your departure time, or move an outdoor activity indoors.
