cheap thrills: the new PRISM data is here!

 Every ten years the 30-year averages for temperature and precipitation are updated. After watching a few times this fall, I finally accessed our local (800-meter resolution) data to see how the numbers have changed.

And here they are!

The average has dropped by 5.76 inches overall. November crashed the most, losing almost two inches in that month alone. January also took a dive, so the wet season overall took a hit. In fact only September has a higher average than before - though many months dropped by a quarter-inch or less. That's hard to do in the dry season, but July dropped .19" and it was already the driest month!

I haven't looked into temperatures so have no comments on the trends on the hill-top. Our seven years have seen big snows and hot weather, as most medium-term samples will show. Our highest ever temperature was easily this past summer though, and many cedar trees have scorched tips as a result.

I've reset my data tab in Excel to record updated deviations. Oh what fun!
