.PREV DISCUSSION /Issued by National/...A cold front will sweep 
into southern Utah tonight grazing the Arizona border and a few 
showers will be possible over the area from Fredonia to Page. A 
moderate westerly flow aloft will develop over the region 
Wednesday and Thursday as a broad mean trough remains over 
Utah/Colorado followed by a ridge building Friday and Saturday. 
This will produce a warming trend with dry and quiet weather going
into the weekend, but a large Pacific trough will be approaching 
the SoCal Coast Sunday or early next week. Medium range models 
disagree on timing the inland progression of this system and it 
may hold off until Monday or Tuesday when the leading edge moves 
into Arizona, primarily bringing increase south-southwest winds 
and a slight chance of showers and thunderstorms by Tuesday.

.AVIATION...For the 06Z package..Primarily VFR conditions are 
forecast over the next 24 hours. An isolated thunderstorm remains 
possible north of KGCN to KPGA line through 12z. Winds will reamin 
breezy and west to southwest overnight before increasing after 18z 
Wed.

&&

.FIRE WEATHER...A cold front moving through southern Utah will lead 
to gusty winds and isolated showers near the Arizona border through 
late this evening. Dry and warmer conditions can be expected through 
Saturday as an area of high pressure slowly buids over Arizona.
