Aviation... 
VFR conditions across the taf sites this evening. Some sites north 
of Houston might go MVFR briefly tonight but should rebound 
quickly after the sun rises. The chance of rain looks very slim 
tomorrow. Precipitable water values fall near to slightly below average for this 
time of year with middle- level ridging starting to build in to the 
area. Forecast soundings also starting to show an inversion around 
850 mb. Because of this have trimmed back mention of rain in tafs.

Previous discussion... /issued 822 PM CDT Tuesday Sep 2 2014/ 


Discussion... 
temperatures have fallen into the lower to middle 80s inland and 
storms have dissipated there. Surge of moisture can be seen coming 
into Matagorda Bay region accompanied by rain showers/thunderstorms and rain given the 
acars profiles don't expect these to make it far inland. Have 
lowered probability of precipitation and altered the wording as well as cleared out skies 
for central and northern areas at least for a few hours. Stratus 
developing a possibility for the west and northwest areas as well 
as patchy light fog. Forecast with less coverage expected 
Wednesday as drier air overspreads the area.

see aviation for 0z taf issuance. 


Aviation... 
mostly VFR conditions expected for the taf sites through the 
issuance. Might get some low cloud development tomorrow morning 
but they should quickly lift after the sun rises. Forecast 
soundings for tomorrow show lower moisture values with pretty good 
instability in the soundings. An upper level ridge will be 
building a bit tomorrow afternoon though so think slightly less 
coverage tomorrow than today. 23 


Previous discussion... /issued 415 PM CDT Tuesday Sep 2 2014/ 


Discussion... 
scattered rain showers/thunderstorms and rain will continue over mainly the northern half of 
southeast Texas through early evening. Storms will begin to diminish with 
the loss of heating. Ts Dolly will make landfall over northern 
Mexico sometime this evening and only bring long period swells to 
the offshore marine zones and slightly elevated tides. A flattish 
500 mb ridge slowly builds into southeast Texas from the east later this 
week and precipitable water values remain between 1.8 and 1.9 inches through 
Friday. Despite the building ridge...500 heights never really 
increase much with values around 590 dm. Convective temperatures also 
remain between 88 and 90 degrees which is reachable. There really 
isn't a trigger for widespread rainfall but you can't rule out an 
occasional rain showers either so will maintain 20 probability of precipitation through the 
Friday. On Sunday...precipitable water values increase to 2.1 inches and both the 
European model (ecmwf) and GFS bring a weak boundary into southeast Texas. Ll convergence 
along the boundary increases Sunday afternoon and coupled with the 
high moisture content...feel rain chances will be on the rise. 
Raised probability of precipitation to chance for Sunday. The upper pattern doesn't look 
conducive for a front to make it into southeast Texas but both models have 
been hinting at the front entering southeast Texas for the last few days. A 
deep upper trough will move into the intermountain west early next 
week. The ridge over Texas will amplify in response to this and 
rain chances will diminish and temperatures will warm a bit. 43 


Marine... 
based on satellite...short-lived Tropical Storm Dolly appears to be 
coming onshore this afternoon. The effects of Dolly...if any...will 
also be short-lived and in the form of a higher period swell across 
the far offshore western waters. A brief time frame between tonight 
and into early Wednesday morning of greater than 6 foot seas...a 
short fuse Small Craft Advisory will be issued this afternoon to communicate this 
elevated sea threat. There is a chance for some minor water run-up along 
Highway 87 during the overnight hours. Overall southeasterlies will 
remain at...or slightly under...20 knots through tomorrow afternoon... 
weakening back to sub-caution conditions by sunset Wednesday. Weak 
disturbances rotating underneath southern U.S. Ridging will occasionally 
make it into the Upper Texas coastal waters. This will provide the trigger 
for return widely scattered rain and isolated thunderstorms over the next 
several days. 31
