.METEOROLOGICAL CONDITIONS (TUE AM - MON AM)...

An upper low is currently traversing NV headed for UT. Satellite and 
lightning detection picking up some thunderstorms over parts of 
eastern NV and into UT earlier this morning. Chances of showers and 
thunderstorms in the forecast over eastern NV today as the low 
exits. Dry conditions for tomorrow as drier air moves in behind that 
exiting low before troughing arrives from the northwest again on 
Thursday. This will generate some showers over the north coast and 
across the CA/OR border through Friday afternoon. Amounts look 
roughly 0.10-0.30" over the Smith Basin and the crest of the 
Cascades down to a few hundredths or so for surrounding areas. 
Additionally some monsoonal moisture looks to move into se CA and 
srn NV in the afternoon Thursday returning chances of some showers 
and thunderstorms to those areas. Models then have another trough 
moving in some time on Sunday or Monday. This may bring additional 
light showers, though the majority of the ensembles are dry.
