[wxqc] Spikes again

[Sam Drinkard]

Dave,

    I'm seeing spikes again on the pressure plots.  This one is from 
today, and the spikes occured at or slightly before 0400 and the 2nd one 
beteen 1745 and 1830z.  First plot is about a 1.75 - 2mb drop, and the 
2nd one roughly the same amount.  Nothing there in that time period 
shows up on wunderground, however wunderground appears to have had a 
dropout from about 1630-1700, then another couple of dropouts up to 
current time of 0400z.  There does not appear any such drastic changes 
in the data they have.  Checked the stations around me, and did not see 
anything that looked like some kind of spike.  Perhaps you can check 
into this and let me know if maybe *I've* got a problem with the 
sensor?  Seems like this is happening every couple or 3 days, and IIRC 
about the same time.

thanks..

Sam
