1133 am CST Sat Nov 21 2009 




Update... 
first period /rest of today/ forecast adjustment and 18z Saturday 
routine taf discussion. 


&& 


Discussion... 
main adjustment for the rest of today was to reduce the amount of 
opaque cloud cover and alter temperatures/dewpoints 
accordingly. Given the greater insolation available for peak 
heating this afternoon...temperatures were raised slightly and 
dewpoints were kept the same or lowered slightly...especially in 
the east and northeast part of the weather forecast office pah forecast area. Although 
there will be some local variance in direction...kept average 
winds this afternoon from the east...southeast. 


&& 


Aviation... 
although it is not climatologically favorable...added a periodic 
mention of MVFR fog to kcgi in the 09-13z Sunday time frame to 
account for slight variability wind wind flow near the Diversion 
Channel next to the observation site. Otherwise...the remaining 
taf locations were kept in VFR category throughout the forecast 
period...with only scattered to broken coverage of cirrus 
spreading in from the west with time.
