NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
645 PM CDT Tuesday Oct 21 2014 


Aviation... 
rain is remaining just west of the kdrt terminal at the present 
time. Chances are too low to mention anything in the taf for now. 
Otherwise...MVFR ceilings are expected once again in the morning for 
del Rio as the best low-level moisture remains confined along and 
near the Rio Grande. Otherwise...VFR is expected for the remaining 
taf sites and light easterly flow will continue.

Previous discussion... /issued 330 PM CDT Tuesday Oct 21 2014/ 


Short term (tonight through Wednesday night)... 
a shallow middle level upper trough over Texas and New Mexico will 
gradually flatten as it moves east across Texas over the next 2 days. 
Dry surface conditions over the eastern half of south central Texas 
will limit the amount of precipitation this system will be able to 
generate as it weakens. Clusters of weak showers and a few 
thunderstorms will cover much of northern Mexico...with scattered 
light to moderate rains expected to spill over into the southern 
Edwards Plateau tonight. Models show the loosely defined trough 
axis to not cross into south central Texas until late Wednesday 
night. However...significant clouds spilling east from this area 
should curb high temperatures over western sections for Wednesday 
and limit the overnight cooling potential over these areas as 
well. 


Long term (thursday through tuesday)... 
model consensus shows the trough axis will bring the most 
coverage of light precipitation chances to south central Texas early 
Thursday before forcing becomes too weak for precipitation late in 
the day. Upper ridging in the wake of the weak troughing feature 
increases over the southwestern US by Friday...leaving a weak surface 
pressure field and mild and dry weather for the weekend. Another 
shallow trough is projected over the western US early next week which 
should increase southerly winds Sunday into Tuesday. The next 
trough has a better chance to bring a cold front and possibly a 
chance of rain for Tuesday.
