.DISCUSSION...
The latest radar imagery shows a few light showers approaching
from the north. However, these are rapidly weakening and may only
produce spotty drizzle at best. The area of low to mid-level
clouds will likely stick around through the night as winds have
remained out of the east/southeast (onshore direction). With this
wind shift, MVFR ceilings (1,500-2,000 ft) become likely
overnight with some slight reductions in visibility possible. The
current forecast brings visibility values down to around 5 to 6
statute miles between 0400-1000 on Monday. Forecast low
temperatures will fall into the low 50s.

Low clouds are likely to burn off by the mid morning on Monday.
Winds eventually shift to southerly which will help raise
temperatures back into the low 70s. This is underneath mostly
sunny skies. Increasing moisture should allow for an increase in
clouds by Monday night. Any shower and thunderstorm chances hold
off until Tuesday and Wednesday, and possibly again late in the
week.
