Hi All,  Today in Boise, the weather noise on the sensor is very, very =
bad.  Over the last few days, is has not been good, but today it is =
offal.   I will check the weather summary tonight to see what has moved =
into the valley.

I live in a valley about 5 miles from the mountains, to the North.  To =
the South it is flat, East and West flat for many miles.
I have heard that cold air can roll into the area, causing noise, and I =
have seen that on the screen.  I don't see wind, rain or things that you =
would think would cause noise.  Just fronts.  Not winds.

At night everything fall down to nothing, nice flat lines, but as soon =
as the sun come up I get the noise.
Most days its not too bad.  I notice it more on a vertical sensor than a =
horz sensor.

I think, it is the air warming and moving down the valley and up into =
the mountains, at night it stops.
On cloudy days it less, but still noticeable, at night it is gone.

Today it was sunny and partly cloudy, the clouds gathered over the =
mountains as if it might rain up there.
No wind or rain here, just a nice hot day.   But the screen is a mess.

Anyone live next to the mountain, with similar issues?

Thanks, Ted
