Area forecast discussion 
National Weather Service Flagstaff Arizona 
925 am MST Sat Nov 21 2009 


Synopsis...aside from breezy southwest winds today...northern 
Arizona will continue to see mostly clear skies...mild days...and 
cold nights through next week. 


&& 


Discussion...a dry trough will pass across far northern Arizona 
through today and tonight bringing periods of middle-to-upper level 
cloudiness and breezy afternoon winds. No significant changes to the 
current forecast are anticipated with generally benign weather 
anticipated through the 7-day forecast period. 


&& 


Previous discussion /245 am MST/...an upper level trough will move 
across the area today with breezy southwest winds and some middle and 
high clouds...but no hope for rain as the lower atmosphere remains 
very dry. Most higher elevation locations will be a few degrees 
cooler...though northeast Arizona valleys should actually be warmer as 
persistent temperature inversions are mixed out. Another trough will 
clip the 4-corners late Sunday...then high pressure is forecast to 
build over the southwest through Thanksgiving. Temperatures will be 
slightly above normal with easterly winds much of the week. No 
precipitation is expected through next Friday. 


&& 


Aviation...for the 18z package...expect VFR conditions with widely 
scattered to scattered high clouds across northern Arizona for the 
next 24 hours. From 18z to 00z today expect breezy SW winds at taf 
sites except kpga. Aviation discussion not updated for amendments. 


&& 


Fgz watches/warnings/advisories...none.
