Area forecast discussion 
National Weather Service Midland/Odessa Texas 
224 PM CDT Friday Jul 18 2008 


Discussion... 
an upper level low near the Texas coast will drift westward the 
next several days with subsidence translating on the west side of 
this feature toward West Texas. Expecting precipitation chances 
the next several days to be confined to the western portion of the 
forecast area...mainly in the mountains and the immediate adjacent 
plains furthest away from the sinking air in the higher middle level 
Theta-E air. The steering flow aloft out of the east is not 
conducive for the storms to translate into the Permian Basin. High 
temperatures in the plains will increase with a decent amount of 
sunshine due to the subsidence. This upper low is forecast to pass 
across northern Mexico early next week with the better middle level 
Theta-E air continuing to reside over the aforementioned western 
section. Will continue isolated to widely scattered showers and 
thunderstorms for these areas Monday and Tuesday. Interestingly 
the guidance is not forecasting higher Theta-E or precipitation 
across the Permian Basin Monday or Tuesday northeast of this 
feature that would occur typically. This will need to be monitored 
the next couple of days. By next Wednesday the upper low will have 
moved west of the forecast area with an upper level ridge building 
southward across the area with easterly middle level flow. This 
pattern does not look conducive to precipitation and will not 
mention even in the higher terrain. Temperatures will continue to 
be near seasonal normals.
