“Dirty High” with Fog/Low, Low Stratus Trapped As of 11 a.m.

November 21st, 2012 at 10:55 am by under Chad's WLFI Weather Blog

There is still a lot of fog & low, low stratus over the area as of 11 a.m. underneath surface high & inversion.  You can see the fog/low, low stratus in the visible satellite image below underneath the surface high.

The fog/low stratus will likely not be entirely gone in the viewing area until 2 p.m.

Thinking we will go mostly sunny-sunny, but will trim high temperatures a hair given the fact that the sun’s heat budget for the day has been partially allocated to burn off the fog/stratus.  I have seen some days that look sunny & warm in autumn-early winter go quickly cool & cloudy from these situations & your forecast is ruined.  Today, I do think it will greatly improve totally viewing area-wide by afternoon as inversion mixing takes over.

I think model soundings have a good handle on the situation showing the inversion weakening & thus more sun appearing this afternoon.

    Chad, this seems like a good forum for a plea to drivers in foggy conditions: TURN ON YOUR HEADLIGHTS. Driving to work this morning from Battle Ground I met no fewer than 10 drivers who stubbornly refused to turn on their lights even when the semi driver behind me and I flashed our lights. Visibility was close to 0. Even if you can see, others can not see you!!!
