[SWODY1] Notice/update regarding email weather bulletins

[Severe Weather Outlook Day 1]

As many of you have noticed there have not been a lot of weather 
bulletins coming to you by email in the last month or so.  The cold 
weather has exposed the slow failure of the LNB (low-noise block 
down-converter) on my Ku-band EMWIN satellite downlink.  When LNBs 
get old, their center-frequencies become very temperature 
dependent.  In other words, the colder outside it gets, the futher 
off-frequency it drifts, until the signal drops to below the noise 
threshhold.  At that point the ingest engines locks up and no more 
message get parsed.

So as long as the temperature stays above the mid-twenties, the data 
will keep flowing.  A new LNB has been ordered, and hopefully the 
four-foot snow drift around the dish will melt about the same time 
the new LNB shows up.

That's the update...it appears to be running smoothly right now with 
the temperatures mild, so we'll see what happens in the next week.

If you are on more that one list, you have received one message for 
each list that you are on.  Apologies for any duplicates.
