| By default, the tool loads with an icon
at all locations where there is data for the current hour. This icon is
shaded green for VFR (Visual Flight Rules), blue for MVFR (Marginal
VFR), and red for IFR (Instrument Flight Rules). The amount of
cloudiness (Clear, Scattered, Broken, Overcast) is also displayed by
this icon - view the legend for the plot key. Placing the cursor
over one of these icons causes a text message to appear which reveals
the cloud coverage/bases and visibility (the two main ingredients
which determine flight category - IFR/VFR/MVFR).
Next, zoom into your region of interest by clicking and holding the
left mouse button, then drag the mouse while continuing to keep the
mouse button depressed. This creates a "rubber-band" which
will be the zoom area. Then let go of the mouse button and the tool
will zoom into that region bounded by the red rectangle.
Now, you can turn on certain variables reported at airports such as
temperature, winds, altimeter setting, etc. by simply choosing which
variables from the checklist found near the center below the map. If
your zoom level causes too much data overlap, the tool will eliminate
lower priority sites in order to keep the map from becoming a terrible
clutter. If you want all sites no matter how cluttered the display may
be, then choose to show all sites (or more) using the checkbox to the
far right (below map).
Once you have choosen to display particular parameters such as
temperature or winds, then placing the cursor over a particular station
location will cause the full raw text METAR to appear.
