Aviation Forecast Discussion

.AVIATION...
06Z TAFS: The region will be in a break between midlevel waves
with drier conditions and VFR skies. The only caveat will be a
20-30% chance for patchy fog or ragged stratus around Couer D
Alene, Sandpoint, Newport, and along the Spokane River in the
vcnty of Felts Field. Temperatures will be several degrees colder
tonight courtesy of drier air in place and some areas of new
snow on the ground. A weaker wave traverses the region during peak
heating on Sunday with 30% chance for -shsn mainly across NE WA
and N ID. This activity will wane with loss of heating and focus
will shift west on a slightly stronger midlevel wave entering
Central WA after 03z. Overall, there are low probabilities for 
widespread restrictions from low clouds or snow through this 
forecast period but this could change after 06z Monday with higher
probabilities for light snow and lowering ceilings. 

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Overnight into 
Sunday morning HREF shows around a 20-30% chance of MVFR or lower  
conditions redeveloping for KGEG/KSFF/KCOE. This could come in the
form of ragged stratus or patchy fog. Best chance for fog will be
in areas sheltered from the steady 10 mph winds coming across the
Basin into the West Plains./sb

------------------------

Confidence descriptors:
Low - Less than a 30 percent chance 
Moderate - 30 to 70 percent chance
High - Greater than a 70 percent chance
