Marine air Starting to move in...
Marine air is starting to move along the coast..we should have a very weak marine push tonight...enough to cut the temps by 5-7F degrees tomorrow. The thermal trough is now moving over the mountains and an onshore pressure gradient has developed. Stratus is starting to push across the coast..and you can see this on an image I have never shown on this blog before...the fog product. By combining several infrared wavelengths observed by satellite we can see low clouds at night..take a look at the figure. See the whiter stuff on the coast..that's the low clouds. The latest surface chart below shows southwesterly and westerly flow pushing in around Hoquiam.
Low clouds may make it into the Strait and perhaps to Shelton and Olympia..but it should burn back rapidly in the morning. If today was a tad hot for you, tomorrow will be heaven.
If you want to see an extraordinary picture from the high resolution NASA MODIS satellite...look at this. You can clearly see massive amounts of smoke from the BC fires and the low clouds off the coast.
Finally, my kidding around with KING-5's hypesters should not be taken as a lack of respect for their weather personnel, which are really top rate. And lets face it, other stations partake in weather hype as well....although to be fair, none of them have ace Jim Forman, who is in a class by himself. And their segment on the heat wave tonight was quite reasonable. Sometime, perhaps after a few glasses of wine, I might blog about the TV weathercasters of our area, but the bottom line will be fairly unexciting..we have unusually good tv weather people in this market. But I better stop before I get into any more trouble.
