Is There a Meteorologist in the House?

This was the forecast from Saturday.  Could someone please explain to me how the winds forecast can be so specific?  I could understand winds between 10-20 mph, but 19? Really?  I'm supposed to believe that the sustained winds were projected to be exactly 19 mph?  Even the gusts forecast seemed unusual, without being rounded to a 5 or 10.  Perhaps the weatherman was just tired of being ignored, and thought if he threw out an unusual number, people would take notice. (Similar to Disneyland's 14 mph speed limit in the parking structure.) If so, it worked.  At least for me.  I haven't heard anyone else puzzling over it, though, so maybe my mind is just a bit too easily perplexed.
