Discussion... 
the upper level system which gave US friday's beneficial rainfall 
will finally exit the region this evening resulting in clearing 
skies across our eastern County Warning Area. There is ample ground moisture from 
the rains and with radiational cooling and light winds overnight.. 
expect patchy fog development late tonight over all but far north.. 
northwest and far southwest portions of the County Warning Area. The shallow fog 
condition should mix out by late morning and with a light southerly 
flow returning to virtually all of the region by midday..should 
have a mostly sunny and mild Sunday afternoon with high temperatures 
around 70. Another round of patchy morning fog Monday..then a 
developing surface low over northwest Texas will continue 
advecting Gulf moisture northward during the day..producing a few 
showers by late afternoon over south central sections. The 
southern part of a rapid moving upper air trough with attendant 
cold front will push through the area overnight Monday and early 
Tuesday with showers and thunderstorms possible along and ahead 
of the front. Clearing and colder Tuesday night with lows in the 
30s Hill Country..40s elsewhere. Mostly sunny but cool Wednesday. 
A Mammoth Ridge-trough couplet dominating the entire U.S. On 
Thanksgiving will anchor a dry surface ridge over south Texas. 
This will result in mostly clear skies but a chilly Thanksgiving 
morning and a mild to cool afternoon. This anchored Dry Ridge 
pattern will keep through next Saturday with return southerly 
flow and moisture late next weekend as the upper level flow 
becomes zonal.
