Area forecast discussion 
National Weather Service Salt Lake City Utah 
850 PM MDT Monday Oct 6 2008 


Synopsis...high pressure will remain over the area through Tuesday. 
The next cold storm system will drop south out of western Canada and 
into the Great Basin late this week...and remain into the weekend. 


&& 


Discussion...flat upper ridge building into the Great Basin will 
remain through Tuesday night. Stable and relatively dry airmass 
associated with the ridge will keep temperatures generally seasonal and 
conditions dry heading into midweek. 


Heights will gradually lower over the basin as the westerlies begin 
to sag south into the area. The development of an high-amplitude 
upper ridge between 130-140w will allow for cold air to pile into 
the basin late in the week. Significant intensification of shortwave 
energy diving south out of western Canada will lead to the likely 
development of a closed low over the basin Friday through the 
weekend. Both the latest GFS and European model (ecmwf) pretty much in agreement with 
the synoptic scale feature...leaving the details to be worked out 
later on. For now much colder temperatures a given...with areas of 
heavy precipitation a good bet toward Saturday and Sunday. 


No update planned this evening. 


&& 


Aviation...VFR conditions will prevail throughout the overnight 
hours at the kslc terminal. Light southeast drainage winds will develop 
between 03-04z. 


&& 


Fire weather...a stable airmass along with fairly light transport 
winds will keep clearing indices on the light side into Tuesday. 
Morning valley inversions Wednesday will inhibit mixing during the 
morning. Good heating and increasing transport winds will raise the 
index during the afternoon. A dry cold front will push indices 
higher on Thursday.

Slc watches/warnings/advisories... 
Utah...none. 
Wyoming...none.
