There are many great Websites to explore for weather details: weather.gov (National Weather Service); weather.com (The Weather Channel); and wunderground.com (Weather Underground)  including the Historical Weather section ( featured in the 1/3/12 Tip) come to mind– but in this week’s Tip we take a look at another great weather site —weatherspark.com –that has many unique features that can be custom tailored like GIS ‘overlays’.  The site is perfectly laid out for anyone who works with GIS format maps, and it’s one of the best I’ve seen for tracking changing wind direction over time, something that is of great interest to birders everywhere during the spring and fall migration periods.   Give it a try and see if it becomes your new favorite!     Tuesday’s Tip — December 1, 2015 (Weatherspark.com)
