Fog that descended on the South Sound on Thursday morning was expected to burn off around lunch time, and then to return that evening.
“Maybe not quite as thick as what’s out there this morning,” National Weather Service meteorologist Andy Haner said.
“We got a really moist air mass in here, especially by standards of early and mid-November,” he said. “And then skies cleared out last night, and that allows good cooling of the air mass.”
Those conditions make for fog, especially in the Tacoma area, which he said tends to be cooler than Seattle and avoids drying east winds from the Cascades.
In between the bouts of fog, Haner forecast some sunshine to poke through the clouds Thursday afternoon.
He said some rain is forecast for the rest of the week, starting Friday night, and pointed out that this month has brought unseasonably warm weather.
“Usually, by now, we’re squarely into cool, brisk-type weather,” he said.
Highs in the mid-60s Thursday and Friday might tie daily records, Haner said. And the region is approaching record-territory for the number of days in November to top 60 degrees. The forecast high Thursday would tie that, and Friday would break it.
