Dirty High: Fog/Stratus Deck Island Under Lid Over Viewing AreaNovember 8th, 2012 at 12:52 pm by Chad Evans under Chad's WLFI Weather Blog
There was so much dense freezing fog this morning at such a depth that a low stratus deck has developed under our surface high in the area. It is sunny to our east, south, north & west, but there is an island of gray stratus & fog underneath this lid & surface high right over our area. Given the weakening November sun angle, it gets harder to burn off stratus as you get farther into the fall & winter season. High pressure usually gives us sunny, nice weather with its sinking air, but it is that sinking air that can trap moisture from a substantial fog event.
That said, thinking stratus deck will continue to erode on the edge through the day & hopefully we will reach mostly sunny skies by late afternoon-evening. With so much heating with temperatures already rising well into the 40s & 50s, this mixing from thermals will likely act as a domino with continued, but slow, stratus erosion.
