.DISCUSSION...
A frontal system will stall to the south of the area through
tonight before settling near U.S. 50 by mid-week. Persistent
easterly onshore flow will lead to cloudy and cool conditions
along with the potential for showers. By Thursday, this system
pulls away to the southeast as a cold front. Weak high pressure
returns over the region by late in the week into portions of the
weekend.
