Online Weather Resources
Knowing the weather forecast is helpful in predicting when
a good flight of raptors will occur. A heavy overcast or
rain will keep numbers down. In the fall, winds from
a northerly direction often associated with a passing
cold front are more favorable for migrating raptors.
The following online resources provide information on both
the current and forecasted weather. The resources
progress from ones that are simple and easy understand to
those that are complex and require some effort to interpret.
Try them out and see which ones you find useful.
If you have other online resource you think others might
find useful send the URL and a short description to
weather@greatblue.com.

Forecast Meteograms provide a compact summary of
a 60 hour forecast for a single location. They are generated every 12 hours.
On one graphic image, meteograms show 60 hour plots of temperature, cloud ceiling, pressure,
and precipitation. Wind speed is graphically shown as wind barbs
at 3 hour intervals which makes it easy to see when the wind will shift in direction
and strength.
It takes a bit of learning but once you've mastered them, meteograms are
very useful.
In order to use meteograms you will have to:
- Learn how to read a meteogram.
- Learn how to convert from Universal Time (UTC) to Local Time.
(Times on the meteograms
are given in UTC which is 4-10 hours ahead of times in North America.
Use the above link to determine how many hours you need to subtract
from UTC times to get your local time.)
To get a "local" meteogram:
Go to the
Unisys Weather
Forecast Meteogram page and select a city
either from the clickable map or from the text links at the bottom of the page.
