Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
301 PM CDT Friday Jul 18 2008 


Discussion... 
warm and dry weather will continue across south central Texas as 
we remain on the subsident side of the TUTT low/inversion trough. Some 
sea-breeze enhanced activity will continue across the coastal 
plains through this evening...but should diminish rapidly after 
sunset once diurnal heating is lost. Seasonably warm temperatures 
are expected over the weekend...with afternoon highs peaking in 
the upper 90s to near 100 across much of the region. Dry conditions 
will also persist...with the only chances for rain extending 
across the coastal prairies from sea-breeze convection. 


A tropical wave in the Caribbean Sea will slowly push westward 
through the next several days. This system will enter the Gulf of 
Mexico by the beginning of next week and will continue toward the 
Lower Texas coast. Rain chances will begin to increase on Tuesday 
as the system approaches the region. The National Hurricane Center 
has indicated that this wave may develop into a tropical cyclone 
over the next few days. Even if this feature does not strengthen...it 
would still bring deep moisture to the region resulting in greater 
cloud coverage and better chances for rain. Due to the uncertainty of 
the timing and location of the system...have stayed close to 
guidance probability of precipitation...with the best rain chances on Wednesday and 
Thursday extending across our southeast and southern counties. 


With the expectation of greater cloud coverage during the middle 
and end of next week...maximum temperatures will be a few degrees 
cooler than the beginning of this week...but still near late July 
normals.
