And there is where the temperature is at, 56 degrees. Heading up to 76 degrees today. Heres what to expect as you head out to morning smog. Also some cool temperatures. And the rest of the week it will be clearing but the air quality will be still poor until they put out that fire near monterrey county which is supposed to take a while. This weekend it will be much cooler and breezy. At least in San Francisco but not so much for the rest of the bay area. And weve been also keeping an eye on whats been happening in monterrey county with that wildfire there. You can see the smoke extending farther inland. And yesterday we did have a westerly wind. Thats what in satellite imagery showed but we are going to see a shift in the wind direction today and that may carry that smoke in different areas.
