hi Jeff:
My bet would be that the GPS isn't getting a good signal from the satelites
because of a dense ceiling layer caused by extreme heat and humidity.
When there is much heat near the ground, and cooler temps up higher, a layer
is created...due to high levels of moisture in the eastern areas of the US
or anywhere near coast lines and large bodies of water, a layer of moisture
adds to the problem.
It can also be great for ground wave DX...50MHZ and above just love moisture
layers, or inversion layers to propigate with.
