It might be too dark or far to see your rain gauge from the house, or you didn't notice the crack in it before... (or you might not want to go check it with your PJs on and sneak back to bed!)
Many otherwise great weather apps are filled with current conditions and 7/10-day forecasts. Unfortunately, this isn't helpful when trying to determine watering schedules or if a site is going to be too muddy for work.
You can zoom in to your home or jobsite location and select rainfall totals for up to three days back.
The site uses Doppler radar technology to provide very accurate estimates of accumulated precipitation. Their maps will display on almost all smartphones, tablets and computers. I've had great comparisons with my own and customers' rain gauges.
