.DISCUSSION...

Weak fronts will waver across the area through Wednesday. A few
showers and thunderstorms will be possible at times through this

will build across the area on Thursday.

Patchy fog may be present each morning (even at airports we only
forecast it out to 30 hours due to forecasting challenges). If it
does develop, it will burn off by mid morning.
