The Flash Flood Watch has expired for SE TX this evening as we head toward a more typical late Summer pattern with scattered afternoon showers.

33 year's ago this evening, CAT 3 Hurricane Alicia was approaching the Upper TX Coast.

Hi everybody.

Well, the slow-moving tropical low that caused all the trouble in Florida, Mississippi, Louisiana and SE Texas seems (that's with a big "S") to have moved on. Can I safely assume my services will no longer be needed on this forum?

Area Forecast Discussion
National Weather Service Houston/Galveston TX
1022 AM CDT Thu Aug 18 2016

.MORNING FORECAST UPDATE...

Radar is starting to get active with showers forming mainly along
the coast. More scattered activity is expected today with still
quite a bit of moisture over the region. Precipitable water values
at 12z for CRP/LCH around 2.2-2.3 inches. Upper level analysis at
500mb shows some ridging developing along the coast but it is
rather flat and elongated. Day time heating should be enough for
storms to develop and re-develop this afternoon. Wind profiles are
rather weak so storm motions will be driven by mesoscale processes
and outflow/cold pool interactions. Rain rates will be a solid 1-2
inches of rain an hour but thinking storm motions like yesterday
may just be enough to not cause flooding problems other than
typical street flooding.

Not much else to update in the forecast other than conditions for
today. Rain chances look to continue through the weekend.

Looks like TD #12 in the EPac may create some trouble this weekend for those of us in soaked parts of south central and southeast Texas. I believe the word "mischief" is appropriate ... one of srainhoutx's faves. ;)
