SO YOU WANT TO FORECAST PRECIPITATION PROBABILITY FOR EVERY HOUR OF THE DAY!

 

1.     Click on this:  http://www.nws.noaa.gov/mdl/gfslamp/statebull.shtml  

 

  1. Click on the state you wish to forecast the hourly PRECIPITATION PROBABILITY.
  2. I have selected New York State.  We will select Albany, New York
  3. To decode the information, click this: http://www.nws.noaa.gov/mdl/gfslamp/docs/LAMP_description.shtml
  4. At the left is a column…7th Line down is PPO Which stands for PRECIPITATION PROBABILITY.(CHANCES OF HAVING PRECIPITATION AT THAT HOUR) A complete time chart is available to all for all time zones in the United States.  Use it.

This lists the forecasted PROBABILITY OF PRECIPITATION for each hour for the next 24 hours.  Pretty simple.

This is how it is decoded: It simply lists the chance of precipitation at that hour in percentages, the higher the number, the better the chance of having precipitation.
