1. The stalled front will remain north of the region for
at least another 36-48 hours however, the environment ahead
of the front is quite conducive for fog. With that, the
introduction of smoke particulates will only enhance the
chance of fog and could lead to super fog.
2. As for rain with the front, it is possible but right
now any rain looks to be light with the front or behind it
on Monday.
