PREV DISCUSSION... /ISSUED 335 PM CDT Mon Jul 16 2018/ 

DISCUSSION...
Hot and dry conditions will prevail across Southeast Texas over
the next week as expansive upper ridging builds across the state
from the Four Corners region. Saharan dust will linger across the
region through Tuesday, but NASA GEOS-5 modeling shows this plume
dispersing beginning this evening through Tuesday with dust likely
unnoticeable by Wednesday. Patchy, intermittent fog may be able to
develop during the early morning hours Tuesday and Wednesday but
increasing subsidence from the ridge should result in enough
column drying to limit fog development by late week. 

As mid-level heights climb into the 594-595 decameter range mid- 
week, afternoon high temperatures will climb into the mid 90s to 
lower 100s inland and upper 80s to lower 90s along the coast by
the end of the week. This is expected to produce heat index values
in the 105-110 degree range with the potential for briefly higher
observed values during the afternoon hours along the coast as the
sea breeze moves inland each day.

MARINE...
The maritime forecast will remain fairly unchanged over the next 
several days as surface high pressure expands across the entire 
Gulf and kills any discernible pressure gradient. Weak 
southwesterly breezes will occur over more western waters and bays
with more of an easterly component to the onshore flow over the 
more eastern waters. Weak breezes will keep average sea heights at
or under 3 feet. High pressure at all levels will also inhibit 
any shower or thunderstorm development through the week. Less than
a slight chance that more eastern Gulf waters could experience 
early day isolated rain activity focused along a potential land 
breeze boundary making it into the nearshore waters. 31
