Weather with Cliff Mass
Fri June 22, 2012
Rain for sure, says Cliff Mass, but summer rain is different
You can watch out not only for rain showers, but perhaps even some thunder showers on Friday, says Cliff Mass, the KPLU weather expert and professor of Atmospheric Sciences at UW.
If you're planning ahead, he says in this week's podcast, Friday afternoon will get the worst of it, with Saturday slightly less, and Sunday tapering off more and warming up a few degrees.
And, if you're wondering, When will the water at our beaches be warm enough to get in?... Mass has some bad news. The early part of summer is when winds conspire to create "upwelling" along much of the Pacific coast, and that makes the water get colder.
As Mass explains on his blog:
Strangely enough, this upwelling is forced by our summer weather pattern in which high pressure builds offshore--with this high pressure producing northerly (from the north) flow along the coast. The northerlies are further strengthened by the warming of the interior and the resulting lower pressure (warm air is less dense).
On the other hand, that same upwelling makes the abundance of marine life, and fisheries, possible.
Do you have a weather question? Cliff Mass and Keith Seinfeld occasionally answer reader questions on the air. Share yours here.
The weekly KPLU feature "Weather with Cliff Mass" airs every Friday at 9 a.m. immediately following BirdNote, and repeats twice on Friday afternoons during All Things Considered. The feature is hosted by KPLU’s Science and Health reporter Keith Seinfeld. Cliff Mass is a University of Washington Professor of Atmospheric Sciences, a renowned Seattle weather prognosticator, and a popular weather blogger.
