NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
808 PM CDT Monday Aug 3 2015 


Discussion... 
sent out a quick update to account for current weakening activity 
across parts of Colorado and Austin counties that formed along the 
sea breeze front. Will probably do another quick update in a 
little bit once the hgx radar GOES ppi no echoes. 42 
&& 


Previous discussion... /issued 630 PM CDT Monday Aug 3 2015/ 


Discussion... 
00z taf discussion in aviation section. 


Aviation... 
radar shows remaining showers and isolated thunderstorms and rain dissipating along with 
a well defined fine line indicating where outflow has merged with 
sea breeze boundary. Boundary should push through kiah shortly 
and turn winds to more southeast/S instead of east. Overall expect VFR 
ceilings for the next 24 hours. May be some ground fog at best at klbx 
and kcxo with winds decoupling. Do not have a lot of confidence in 
that happening since still think there will be a decent T/dew point 
spread. GFS/NAM/WRF-nmm still show potential for isolated rain showers/thunderstorms and rain 
tomorrow afternoon as area of higher moisture with precipitation water 
values greater than 2 inches moves over the area. Again not a lot 
of confidence so will leave out of taf but enough confidence to at 
least mention possibility. Likely time frame will be from 20z-00z 
in the afternoon and kiah southward towards the coast.

Previous discussion... /issued 339 PM CDT Monday Aug 3 2015/ 


Discussion... 
a seabreeze was working its way across Galveston...Brazoria...and 
Matagorda counties at 3 PM. Isolated showers were trying to 
develop mainly west of Angleton...and may develop along the 
seabreeze as it pushes further inland. An upper air analysis of 
the 12z data showed a ridge overhead of southeast Texas from 700 
mb up through 200 mb. Subsidence from the ridge will probably keep 
isolated showers and thunderstorms from developing north of the 
Interstate 10 corridor. 


The models forecast a weak surface boundary to push inland tonight. 
A more moist airmass will develop over the area behind the 
boundary and overnight/early morning lows tonight will be higher 
than from over the weekend. The higher resolution models...namely 
the arw... actually bring better chances of rain over the 
southwestern and coastal counties on Tuesday. This is tempered by 
the global models which keep the majority of the rainfall along 
and off the immediate coastal areas and generally east of metropolitan 
Houston. 


The main story for the middle and latter part of the week will be 
daytime heat. By Wednesday some locations may start to see 
afternoon heat indices approach the 103 to 108 range. Daytime 
highs over the middle and later part of the week will reach into the 
upper 90s to around 100 for most locations inland of the coast and 
bays. The heat indices may also become an issue toward the end of 
the week as well. For now the models are keeping the heat indices 
below criteria but do expect some locations to reach to near 108 


40 


Marine... 
isolated showers and thunderstorms extend over the coastal waters 
between Freeport and southern la that are associated with a weak 
warm front that is slowly approaching the Upper Texas coast. This 
front should gradually move inland...however precipitation will be 
limited in coverage by sinking air aloft. 


Light northwest winds will become southerly and increase later this week as 
a ridge of high pressure builds over the eastern Gulf and a low 
pressure system deepens across the south Central Plains. Rain 
chances will remain low through the period. 44 


Previous discussion... /issued 1245 PM CDT Monday Aug 3 2015/ 


Discussion... 
please see 18z aviation discussion. 


Aviation... 
isolated light rain showers are developing along the sea breeze 
along the coast SW of kgls. These showers will not make it far 
inland before dieing out. VFR conditions and light and variable 
winds to continue for the next 24 hours. 44
