A high pressure ridge (“Arch” shape on the jet stream) is keeping us cold with some sunshine, as long as the fog clears. So, for the rest of the work week we’ll see at least some sunshine after the late night and early AM fog and/or freezing fog clear out. That also means that our air quality is suffering with the sinking air of high pressure holding on to the pollutants at the surface. The ridge will slide over then past us allowing more clouds and maybe a chance of precipitation returning over the weekend as a cold front moves in from the northwest.
