Short term (today through sunday)... 
a weak upper level trough slowly moves across the area today into 
tonight. Hi-res models show scattered to numerous showers and 
thunderstorms across much of the area with less coverage along the 
Rio Grande. Precipitable waters  in the 1.4 to 1.8 inch range indicate locally 
heavy rainfall is possible. Rainfall amounts range from less than 
1/10 inch out west to 1/4 to 1 inch with isolated totals of 2 to 4 
inches east. Can not rule out some gusty winds and small hail with 
the stronger storms. On Sunday...an upper level ridge starts to 
build into Texas from Mexico. Residual deeper moisture allows for 
isolated showers and thunderstorms to develop. Due to clouds and 
rain...temperatures will be slightly below average. 


&& 


Long term (sunday night through friday)... 
the upper level ridge builds a little more by Monday with no rain 
due to subsidence and slightly less moisture. The upper level 
ridge weakens Tuesday through Thursday as an upper level trough 
passes by to the north across the southern rockies into Southern 
Plains. Deeper moisture returns as middle level flow turns southerly. 
Expect isolated showers and thunderstorms out west Tuesday 
evening and Wednesday afternoon into Wednesday night spreading to 
all areas Thursday into Thursday night. On Friday...subtropical 
ridge begins to strongly build over the area with no rain chances. 
Temperatures closer to average can be expected.
