[wxqc] CW5627

[Gerry Creager N5JXS]

Because you and several of the other stations in the area saw the spike, 
then dip, I am forming the opinion (in the face of caffeine deficiency 
this morning) that you had a real event that cause an over pressure 
spike, and that your site had a transient anomaly that caused the 
erroneous reading.  Lightning is as likely as anything.

I should have gone to my archives last night and looked at the storms in 
your area but I was a bit distracted with honey-do chores.
