National Weather Service Houston/Galveston Texas

Update...

Discussion... 
at 14z...a weak trough of low pressure extended from north central 
Louisiana S-SW across the Upper Texas coast to a weak area of low 
pressure over northern Mexico. At 850 mb...abundant moisture 
lingered over East Texas with an 850 mb trough axis oriented north 
to south from western Arkansas to the western Gulf. 700 mb 
moisture was also widespread from Texas to Mississippi with a weak 
trough axis noted from eastern Oklahoma to Palacios and then out 
over the Gulf. A 500 mb trough axis lingered over East Texas. At 
250 mb...a well defined trough axis extended from the Central 
Plains into central Texas. A 55 knots speed maximum extended into East 
Texas but southeast Texas looks to be in the subsident region of the speed 
maximum with the best lift focused over the western Gulf. 12z 
soundings show rich tropical air in place with precipitable water values between 
2.4 and 2.6 inches. Convective temperatures range from about 84 to 88 
degrees across the area and this threshold should be met later 
this afternoon. Short term models keep things dry this afternoon 
but with southeast lying to the east of the 500 mb trough axis...low 
convective temperatures and deep tropical moisture in place...feel at least 
scattered rain showers/thunderstorms and rain will develop later today. Temperature forecast looks on 
track as does sky cover. New zones out by 1045 am. 


Small changes to the marine zones as well. Issued a scec for 
marine area as winds are around 16 kts with seas of 4 feet. Much 
of this is the by product of convection and winds/seas will begin 
to subside once convection weakens and moves east. 43

Discussion... 
see aviation for 12z taf discussion. 


Aviation... 
expect scattered showers and thunderstorms to persist along the 
coast and offshore through the taf period. Inland coverage and 
northward extent of convection remains somewhat difficult. Most 
inland sites should remain dry through late morning with cll/uts 
least likely to see any activity at all. Aside from convection 
expecting VFR conditions to prevail for much of the current taf 
period once ceilings begin to improve by middle morning. 38
