PREV DISCUSSION... /issued 718 PM CDT Sat May 27 2017/

DISCUSSION...
For the 5/28/17 0000 UTC TAF package.

AVIATION...
Prevailing MVFR CIGS already developing and/or continuing at the
coastal sites early this evening, with these lower CIGS expected
to spread inland through the rest of the evening. Could see some
IFR CIGS as well based on latest numerical guidance and model
data, but have left this out for the time being and will continue
to monitor OBS/trends through the evening. Winds are expected to
be generally light and from the south. CIGS will be slow to
improve again tomorrow amid a very moist airmass in the lowest few
thousand feet trapped beneath a warm and dry layer aloft.

PREV DISCUSSION... /issued 421 PM CDT Sat May 27 2017/

DISCUSSION...
Clouds finally broke this afternoon as temps have climbed into the
mid to upper 80s...as the winds finally broke. Looking for clouds
to redevelop overnight. With southerly winds and afternoon dew
points in the mid 70s... morning lows are prog to drop into the
mid to upper 70s.

Tmrw will see the front over the midwest begin to make its way
down into the region. Looking for scattered showers and
thunderstorms Sunday afternoon and increasing into Monday and
Tuesday as the next front looks to stall along the I-10 corridor.
As a result temps will be a bit cooler from area rains. By midweek
though another front looks to drop down into the southern
states... although this next front looks to washout it will help
the boundary that will be in place and therefore rain chances
continue but the coverage is expected to diminish but will
continue through the rest of the work week.
