00z taf discussion in aviation section.

Aviation... 
expect there to be some decent cirrus overnight coming in from c 
Texas ahead of an upper level trough axis over the Red River. Low 
level moisture will increase a little so may be some scattered stratocu 
in the morning across the area. Overall expect VFR ceilings with lone 
exception being kcxo which could see a hour or two of restricted 
visibility at MVFR levels.

Previous discussion... /issued / 


Discussion... 
a relatively pleasant Saturday afternoon is in progress across 
southeast Texas with 3 PM surface observations showing 
temperatures in the upper 80s to low 90s and relative humidities 
generally around or under 50 percent. Visible satellite imagery 
shows a scattered to broken cumulus field having developed across 
the coastal counties ahead of a weak sea breeze with cirrus 
creeping into the northern counties in advance of a southward 
moving West Texas shortwave. Farther east... the middle-level trough 
mentioned in the afd for the morning package had moved little and 
stretched roughly from the Great Lakes southwest into North Texas 
per afternoon water vapor imagery. 


Little moisture return for the region occurred today with GPS met 
precipitable water estimates remaining around one inch between 
this morning and this afternoon. The middle-level trough axis will 
dig farther south into Texas in response to the West Texas 
shortwave moving into south central Texas later tonight... but our 
presently dry airmass will preclude much in the way of rain 
chances for the region through the remainder of the weekend. For 
tonight... dry air in place may allow a few rural locations to 
fall into the upper 60s with most locations dropping into the low 
70s to near 80 along the coast. 


12z guidance is in fairly good agreement that the middle-level 
trough will remain draped across the region through Tuesday... and 
this feature coupled with returning moisture will bring rain 
chances back into the forecast. GOES sounder imagery shows deeper 
Gulf moisture well removed from the Texas coast this afternoon... 
roughly along and south of a line stretching from Tampico Mexico 
northeast towards Gulf Shores Alabama. Guidance was fairly 
consistent in bringing this higher precipitable water air back into the region 
late Sunday into early Monday as a more persistent southerly/ 
southeasterly onshore flow becomes established. Starting 20 probability of precipitation 
for the coastal waters early Monday morning... with rain chances 
spreading inland /20 to 40 probability of precipitation/ through the middle of the work 
week. Best chances still appear to be along and south/east of the 
59 corridor where the greatest moisture will reside. Otherwise... 
temperatures near to slightly above normal /low to middle 90s 
inland... upper 80s to near 90 along the coast/ are expected for 
the remainder of the week. 


Ridging begins to build back over the region towards the end of 
the week and attempts to shunt the middle-level trough east of the 
region and over Louisiana. Maintaining low end probability of precipitation for the end 
of the week as this happens however with some disagreement in 
medium range guidance on how far east this feature will actually 
move. 


Huffman 


Marine... 
with weak high pressure lingering off to our east...onshore winds 
(5 to 10 knots most of the time...10 to 15 knots occasionally) 
and low seas (generally 1 to 2 feet) will persist across the 
coastal waters for the remainder of the weekend and through much 
of the upcoming week. A slight chance of rain returns late Sunday 
night or early Monday morning as low level moisture slowly deepens 
across the region...and rain chances will remain in the forecast 
for much of the upcoming week. 42
