.PREV DISCUSSION... /issued 324 PM CDT Wed Jul 26 2017/

DISCUSSION...Have seen a few showers develop over interior
southeast Texas and lower Acadiana early this afternoon along
seabreeze. Activity will remain limited in an increasingly dry
atmosphere. Otherwise, satellite imagery depicting scattered cu
across the area while temperatures have warmed into the low 90s at
all sites with the exception of the immediate coast. With
dewpoints in the mid 70s, apparent temperatures are reaching into
the 100-105 range. A few sites are reporting a degree or two
above.

No major changes to forecast. Dry weather pattern expected through
the remainder of the work-week. This as a persistent mid-level
shear axis which assisted in the development of rains across the
forecast area for the earlier portion of the week gives way to
high pressure expanding east and southeast from the southwest
CONUS. Will be maintaining some very high apparent temperature
numbers and will be at least flirting with our heat advisory
temperature of 108 plus. Will continue to monitor.

Rain chances return Saturday into Sunday as a late season front
approaches and moves across the area. GFS suggesting FROPA during
the late afternoon into the evening Saturday, while the ECMWF is
somewhat slower. Will be holding onto a blend solution at this
time which maintains pops into Sunday. Boundary is expected to
bring a brief but much appreciated lowering of dew points with
its passage. Dry weather returns for Monday, with rain chances
returning Tuesday.

MARINE...High pressure will continue to hold over the northwest
gulf through the remainder of the week. Light primarily south to
southwest winds can be expected maintaining low seas.
