NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
439 am CDT sun Aug 31 2014 


Discussion... 
although there was plenty of tropical moisture and lift from an 
upper level trough axis...the majority of convection formed in the 
Gulf of Mexico and moved into East Texas and SW La. Lake Charles ended 
up with 7.87 inches of rain for yesterday. There is a similar 
environment in place today with tropical moisture still over much 
of southeast Texas and Upper Texas coast. The trough axis is slowly weakening 
but still could be a focus for convective activity. Both 00z 
lch/crp soundings showed 2.2 inches of precipitation water and GOES 
sounder data also depicts a swath of tropical moisture stretching 
SW to NE across the Texas coast. Based on water vapor imagery trough 
axis should be moving out of the area as upstream short wave 
trough moves across The Rockies and into the plains later 
today/tonight. This should also help advect tropical moisture over 
the region this morning and afternoon. Hi res models WRF- 
arw/rap/hrrr develop convection along the Upper Texas coast and move 
it into the coastal counties around 12z this morning. Radar 
already showing some shower activity from Matagorda Bay and 
offshore. This seems to be matching the trends in the short range 
hi res models. The NAM/GFS/ECMWF also support the idea of a swath 
of precipitation embedded within main tropical moisture axis. Decided to 
keep mention of 60 probability of precipitation. Again with this much moisture stronger 
storms will be capable of 1-2 inches of rain an hour. Accumulated 
precipitation totals from 06z hrrr show swath of 2-4 inches of rain by 
21z this afternoon so isolated higher amounts of rain will be 
possible. Models do indicate rainfall coming to an end late 
afternoon and evening so decreased rain chances for the afternoon. 


Overall moisture trends in NAM/GFS keep nearly 2 inches of precipitation 
water over the Texas coast through the middle of the week. A tropical 
wave in the northwest Caribbean should be moving across the Yucatan today 
and tomorrow. NHC gives this wave a 50 percent chance of becoming 
a tropical cyclone over next 5 days. Its best chance to do so per 
latest model guidance will not be until it emerges in the Gulf. 
Even then only the NAM really develops the system into a closed 
circulation. The GFS/European model (ecmwf) keep it as an open wave which has been 
way more consistent than the NAM. Overall impact to Texas will be to 
keep a fetch of deep moisture off the Gulf in place. This should 
allow for daily rain chances for the next week with day time 
heating driving convective trends. Coverage in convection will be 
the real issue as global models establish a broad elongated upper 
level ridge over much of the southern U.S. The strength of the 
ridge is also a question so difficult to gage how much subsidence 
will be occurring due to the ridge. With these factors in mind the 
forecast will keep at least some mention of thunderstorms each 
day. It looks like the higher rain chances will be Tuesday/Wednesday as this 
is when tropical moisture from the tropical wave may impact the 
area. Forecast will go with 30/40 probability of precipitation for these days with 20 probability of precipitation 
for the rest of the week. 


Temperatures for the week will be above normal but still the more 
typical Summer time temperatures. Min temperatures in the middle/upper 70s 
will be expected with maximum temperatures in the low/middle 90s. Temperatures will be 
greatly influenced by convection and resulting cloud cover. As it 
stands...with 100f not expected for a high temperature at kcll or 
kiah today...the streak of not reaching 100f for a high 
temperature continues into September. Hopefully it stays that way 
for the rest of the year.

Marine... 
scattered showers and thunderstorms are expected to develop this 
morning across the coastal waters as deep tropical moisture moves 
back into the region. Expect onshore flow to persist through much 
of the upcoming week. Wind speeds will increase late Monday night 
into Tuesday and caution flags may be needed for the coastal 
waters. 38
