Ladyandtramp.com: NWS Digital Forecast Cloud Cover Plot

NWS Digital Forecast Cloud Cover Plot

Amateur astronomers pay attention to the sky and how clear it is. Years ago, we all waited until the evening news to look at the 15 second glance at the satellite image to decide if we should drive out to dark skies to view the stars or not. Today, not only can you get satellite images online in 80 zillion different ways, but you can now also get forecasts for sky cover.

This uses Experimental NWS digital forecast data for sky cover for a 5x5km "grid" of space. Use at your own risk (or fun). Subject to change at any time. Generally, NWS updates the data every hour, but different forecast offices around the county update as often as every three hours or as little as twice a day.

Click on the link above each plot to see these data plotted in a different way. These data are updated 35 minutes past the hour. These CSC like displays are made with apologies to Clear Sky Clock creator Attilla Danko! You are welcome to make comments to bbunge@ladyandtramp.com.
