Area Forecast Discussion
National Weather Service Houston/Galveston TX
1215 AM CDT Tue Jun 19 2018

.AVIATION...
Looks like a band of moderate/heavy rains from the Gulf is setting 
up across Galveston/Harris counties for the overnight hours. Winds
are also increasing as the low-level jet develops. And so, for the
short term, TAFS for the IAH/HOU/SGR/GLS are expected to remain on
the messy side. Did keep precipitation going for most sites tomor-
row as this upper low lingers over the region. MVFR/LIFR CIGS will
likely prevail. 41

.PREV DISCUSSION... /ISSUED 1031 PM CDT Mon Jun 18 2018/ 

UPDATE...
Rain showers have been overall lest robust so far this evening
than they were during the day today. It appears that the banding 
of showers and storms over the Beaumont area has weakened quite a 
bit and a new area of banding has set up near Matagorda Bay.
However, rain rates with the stronger showers have only been in 
the neighborhood of 1 inch per hour so far. More robust convection
should begin to develop during the overnight/early morning hours 
somewhere along the coast, but models have certainly been 
struggling with location of the heaviest rains so far. WPC has 
upgraded the area around and east of Galveston Bay to a moderate 
risk in the Excessive Rainfall Outlook for tonight as that general
area received several inches of rainfall already today and any 
more heavy rainfall overnight would likely lead to flooding.
