This week will be remembered for gusty winds and cool temperatures. A chilly low pressure trough will rotate into the Pacific Northwest over the next couple of days, kicking up gusty winds (SW 15-25+ mph) and cooling us down into the mid to low 70s through the work week before a ridge builds back in for the weekend, heating us back into the 80s on Saturday and possibly into the low 90s for Sunday.

One reader wrote in with the following: “Can you have lightning without thunder?”

No, you really can’t. Each bolt of lightning nearly instantaneously heats of the air to about 50,000 degrees F, and that’s going to make some noise. But it is possible see lightning that is too far away to hear. Usually the sound from any lightning that is more than 7 or 8 miles from your location will dissipate before it gets to your ears. It does produce the thunder, but you won’t hear it unless you are close enough. I guess if a tree falls in the forest and there is no one to hear it, it still does make a sound.
