Re: TS Polo: rain report & heat question

Polo is past us and slowly heading northwest out to sea. We are probably done with most of the wind and rain by now. Hopefully Baja won't get much from Polo. They've had too much already!

Wednesday we got 0.08"/2mm, yesterday we got 1.08"/27mm, and today so far we got 0.52"/13mm. Storm total so far: only 1.68"/43mm.

That's quite a bit less rain than expected. One reason might be that the storm was getting most of its northern quadrant pushed away from us by some upper-level wind shear yesterday and today. In this interactive map from the NHC, you can see that most of Polo's upper-level clouds have been pushed to the south of the low-level center of circulation. Yesterday it was the northeast quadrant (closest to us) that was somewhat missing.

To answer Mark's question about this summer's temperatures: this summer (June thru August) has been hotter than the average, according to the numbers. Our afternoon high temperatures this summer have been several degrees higher than the historical average (dataset: 2004-2013.) Not all of this delta can be blamed on the data shift that happened when I took over the data collection from Deanna in September 2011 (my location down in the flats is warmer than Deanna's up above the church, but only a couple or 3 degrees(??)) Here are the numbers (in °F only for less data clutter):

Jun Tmax: historical avg = 87.5, Jun 2014 = 92.2, Delta = +4.7
Jul Tmax: historical avg = 88.0, Jul 2014 = 93.1, delta = +5.1
Aug Tmax: historical avg = 89.0, Aug 2014 = 92.7, delta = +3.7

Definitely the last few weeks have been cooler because of all the storms, but before that it was a pretty hot summer. Soon I'll post a more comprehensive historical temperature analysis (with spinning 3-D charts and flaming graphics and everything!)

And we are not alone: "Earth Has its Warmest Summer and August on Record"
