Area forecast discussion 
National Weather Service Midland/Odessa Texas 
219 PM CST Sat Nov 21 2009 


Discussion... 
not much has changed from the previous forecast package. The first 
half of the forecast will be characterized by slowly warming 
temperatures thanks to weak upper ridging or zonal flow across the 
area. This will also greatly limit low level moisture return 
ensuring very dry conditions. 


Models are getting in better agreement with the upper level low 
that moves into the Central Plains the middle of next week. This 
feature will send a cold front to our doorstep by peak heating 
which will move south overnight bringing about a period of cooler 
temperatures. Have trended this forecast at or below mex guidance 
the entire period as it has been a bit high lately...particularly 
on low temperatures. Thanksgiving morning should be the coldest morning 
with clear skies and very little wind. The upper low will become 
stationary near the Great Lakes region which will keep Texas in a 
persistent northwesterly flow which will continually reinforce the 
cool air at the surface. So while there will be some warming late 
next week...it will be very gradual.
