NWS Forecaster Discussion
983 fxus64 kewx 182001 afdewx 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. && Preliminary point temps/pops...
