Sun Returns This Weekend

By Angela Zalucha
STAFF METEOROLOGIST

Before you start getting excited about working on your November tan, the return of the sun this weekend is both a good and bad thing. Obviously a sunny day puts most people in a good mood, unless you’re homesick for Seattle or England. But you should take a moment to thank all of the clouds we had last week, since they helped keep the temperature around a nice 60 F (16 C). Clouds act like a blanket by absorbing some of the radiation emitted by the surface and reradiating it back down instead of letting it escape into space. This is the greenhouse effect. You may have heard that term with respect to global warming, but in some cases, the greenhouse effect is a good thing. In addition to clouds, the atmosphere itself also contributes to keeping the planet warm; if we had no atmosphere, the average surface temperature would be -2 F (-19 C)!

Today’s rain will end by this evening, as a low pressure system exits the region. This weekend and early next week are dominated by high pressure, so expect partly to mostly sunny skies and a return to average temperatures.
