SHORT TERM...Tonight through Thursday. The deep upper low over
the central CA/NV border today is expected to move to ID on Wed.
Showers and a few aftn/eve tstms will become more widespread
tonight thru Wed. The upper low moves into MT on Thu...with
precip shifting to near the WY border. Temps will remain cool thru
Thu. Brisk northeast winds should settle down this eve.

LONG TERM...Friday through Tuesday. Flat upper ridging will keep
the area dry and warmer thru Sun. The GFS and ECMWF have flipped
for Mon/Tue...with the GFS bringing a trof into the Pac NW and the
ECMWF going dry with flat ridging. Will leave precip out of the

AVIATION...There will only be a slight chance of mainly
mountain showers and thunderstorms across the area this afternoon

showers this afternoon. An upper level low over Nevada will lift
over our area bringing showers across all TAF sites late tonight

into Wednesday bringing good precipiation chances particularly over
the mountains. By Thursday afternoon look for drier conditions with
rising temperatures over the weekend as high pressure ridging builds
in. Expect breezy winds and a chance of precipitation particularly
over our Northern areas late Sunday through Tuesday as a couple of
