Aviation...18z taf cycle/ 


Scattered MVFR decks remain across central tafs sites although 
central terminals are currently reporting VFR. Solid MVFR continues 
at kdrt with ovc030 stratus deck. Visible satellite trends indicate 
quicker erosion over the past hour and thus kdrt should be VFR 
within next 1-1.5 hours. Continued mixing elsewhere will lead to VFR 
conditions prevailing this afternoon. Some isolated/scattered rain showers will develop near 
kvct and move northwest towards ksat/kaus 21-01z and have continued the 
vcsh wording. Surface winds this afternoon will be 10 knots or less from the 
east-southeast. Rain showers activity will dissipate through the evening with return of 
low clouds after 08z. MVFR and IFR decks look quite probable again 
Thursday morning across much of south-central Texas per NAM and GFS 
bufr soundings.

Previous discussion... /issued 409 am CDT Wednesday Sep 2 2015/ 


Short term (today through thursday)... 
south central Texas remains between a ridge of high pressure 
centered over The Big Bend region and an elongated and weakening 
middle-to-upper-level disturbance that extends from west Arkansas to the southeast 
Texas Gulf Coast. Scattered showers and thunderstorms are developing 
along the Gulf Coast in the vicinity of and east of this shear 
axis from crp to lch with more significant coverage near and east 
of an mesoscale convective vortex centered near Freeport. Hi-res models suggest these 
showers may affect Lavaca...Fayette...and Lee counties in our County Warning Area 
through the morning hours...before daytime heating and a sea 
breeze trigger isolated to scattered showers and thunderstorms in 
the coastal plains that will gradually decrease in coverage and 
dissipate as they move into the I-35 corridor. 


On Thursday...global models suggest that the persistent upper 
level low will continue to weaken and become an inverted trough 
that retrogrades west on the south side of a building ridge over West 
Texas into OK. This will cause a temporary 0.2-0.4 inch surge of 
precipitable water values across the County Warning Area...enhancing the sea 
breeze to cause scattered showers and thunderstorms in the coastal 
plains and isolated showers and thunderstorms as far west as The 
Hill Country and Edwards Plateau. In addition...an increase in low 
level moisture should cause low stratus to persist a bit longer on 
Thursday morning than they will this morning. 


Long term (thursday night through tuesday)... 
isolated showers and thunderstorms extending to the I-35 corridor 
along the sea breeze front should occur on Friday as the ridge 
continues to build in from the west. Global models indicate the 
ridge will strengthen significantly on Saturday and Sunday...but 
deep moist southeast flow should at least trigger isolated showers and 
thunderstorms in the coastal plains. Sunday should be the hottest 
day of the period with highs in the middle-to-upper 90s before 
temperatures gradually decrease as the ridge slowly weakens on 
Monday through the first half of next week.
