Area Forecast Discussion
National Weather Service Houston/Galveston TX
630 PM CDT Thu Aug 17 2017

.AVIATION...
Radar pretty quiet across SE TX this afternoon so far, but will be
keeping an eye on a couple of spots. One over the north/central FA
(around CXO) where an outflow from earlier convection has stalled.
The other locations concerns the large area of storms over Central
TX at this time. Will have to keep close tabs on CLL for the poss-
ible inclusion of SHRA/TSRA this evening. At this time there is no
mention of precipitation in the TAFS for until tomorrow. Otherwise
will be keeping MVFR CIGS in for northern sites for early tomorrow
morning. 41

.PREV DISCUSSION... /ISSUED 332 PM CDT Thu Aug 17 2017/

A heat advisory remains in effect for most of the area through 7
PM. The showers and storms that passed through the Piney Woods
earlier today have all pretty much dissipated at this point, and
quiet (but hot) weather is expected for the rest of the evening.
Not a whole lot has really changed from the previous forecast,
with ridging largely in place through the next several days. This
will lead to hot and humid afternoons, with heat indices nearing
heat advisory criteria (108) in some locations. Starting on
Sunday, an inverted upper trough pushes towards the area, cooling
high temperatures down just a touch and allowing rain chances back
into the forecast. The upper trough will likely remain in the
vicinity through at least mid week, but models are diverging on
where it ends up after that. The ECMWF keeps the troughiness in
place through the rest of the forecast period, while the GFS
pushes the trough westward over Mexico and sets up ridging
overhead once again. PoPs have been capped at 20% for Thursday
until the models can (hopefully) get a better handle on it. 11

MARINE...
Lighter winds and lower seas can be expected from the end of the
week into the middle of next week as Gulf of Mexico area high
pressure edges closer to the northwestern Gulf. Rising rain
chances are anticipated early next week as a disturbance moves
westward across the area.  42
