Discussion... 
see aviation for 6z taf issuance.

Aviation... 
VFR conditions across the area currently. We still look on track 
for some possible restrictions in visibility at klbx and kcxo. 
Crossover temperature is around 53f at both sites. Looks like kcxo 
will get there not sure about klbx. This afternoon upper level low 
will continue to exit the area with the next system approaching 
from the west. The pressure gradient remains weak which should 
help to keep winds tame but with the approaching upper low cirrus 
will start to cover the area. VFR expected this afternoon. 23

Previous discussion... /issued 920 PM CDT Friday Apr 18 2014/ 


Discussion... 
very few changes made this package with a few tweeks to sky cover 
and a few other fields. Based on satellite trends and position of 
upper ridge...expect areas of high cloud to contine to steam 
toward the area...but likely nothing much as long as we are east 
of the upper ridge axis. Upper ridge axis shifts east of the 
area Saturday with some increasing high clouds then. Temperatures and 
winds look on target. Also no precipitation is expected. 46 


Previous discussion... /issued 551 PM CDT Friday Apr 18 2014/ 


Discussion... 
see aviation for 0z taf issuance. 


Aviation... 
mostly VFR conditions expected through the taf issuance. This 
morning there is a chance of some reductions in visibilities as winds 
decouple. A cirrus deck is also forecasted to move in from the 
west as the next system approaches southeast Texas. The cirrus 
should help visibilities to remain unrestricted except at rural 
sites such as kcxo and klbx. 23 


Previous discussion... /issued 345 PM CDT Friday Apr 18 2014/ 


Discussion... 
with light cold air advection/upper ridge holding in place a bit longer...looks 
like dry/mild weather to persist across southeast Texas through the weekend. No 
significant return of moisture until late sun...but models keep- 
ing with the drier trend as the next upper trough takes a more northerly 
track across the Central Plains late sun through Tuesday. This system- 
tem prognosticated to bring another weak front into the area Tuesday as an- 
weak upper ridge builds over the state. This reinforcing airmass 
to bring drier/cooler conditions briefly around middle week. 


Development/passage of the next upper trough across the northern plains 
during the latter part of the week will help the return flow re- 
establish itself over the area. This should Herald the return of 
low level moisture (and warmer temps) during this timeframe. Not 
terribly keen regarding the return of low probability of precipitation until next Friday or 
so (and possibly next weekend) with a slightly more active upper 
(subtropical) jet. 41 


Marine... 
light onshore flow resumes Saturday and continues into midweek. Low 
seas will persist. Weak front will make its way into southeast Texas on Tuesday 
but likely stall before reaching the coast. A tightening pressure 
gradient will lead to just slightly higher southeast winds/seas during the 
2nd half of the work week. 47
