.AVIATION...
Thin band of 600-1000 ft cigs moving inland and toward the metro
airports. Not seeing much behind it attm, but guidance is showing
them (along w/ patchy fog) filling back in overnight. For the 6z
TAF package, planning on taking things down a little bit faster
than the previous one. Not a whole lot of confidence though so
would anticipate amendments. Cigs should break and scatter out
during the mid/late morning hours with breezy southerly winds
becoming the main wx concern for the rest of the daylight hours.
Looking for MVFR conditions to redevelop Sunday evening.  47

.PREV DISCUSSION... /ISSUED 902 PM CDT Sat Mar 25 2017/
A much quieter evening than 24 hours ago...clear inland skies to
partly cloudy along the coastline. This morning`s front stalled
along the coast with drier air slowly filtering into the region
..lower 50 dew points into the city with coastal lower 70 Tds. As
southwesterly coastal breezes back more southerly...per the
washing out of the remnants of today`s frontal boundary...southern
county middle to upper 60 dew points will creep further inland.
This will create lower dew point depressions as ambient coastal
/central interior county evening temperatures in the upper 60s to
lower 70s fall into the low to mid 60s past midnight. This will
produce an environment conducive to fog development...possibly
more dense over those areas that received higher Fri-Sat rainfall
and still have moist grasses or soils. Slow post-sunrise
improvement to a stratus deck tomorrow morning...scattering out to
partly cloudy by early afternoon. A shortwave upper trough
passing into the Central Plains tomorrow will lower inland
pressures enough to generate a tight onshore pressure and produce
moderate daytime southerlies. This stout onshore flow will advect
ample moisture inland...equating to a partially cloudy afternoon
with MaxTs in the near 10 degree above normal inland middle
80s/coastal lower 80s. 31
