.PREV DISCUSSION...
SHORT TERM...Today through Friday...Monsoon moisture from the
south will generate another round of thunderstorms in southern
parts of our forecast area this afternoon and evening.  Storms
may bring wind gusts up to 50 mph.  A cold front late tonight
will shift the monsoon moisture east and out of our CWA
Wednesday leaving us sunnier, drier, and a few degrees cooler.
Clear skies will continue Wednesday night and Thursday, but
monsoon moisture will again begin to surge northward Friday
bringing clouds again to southern areas, with thunderstorms
possible late Friday.  Thursday and Friday will also be several
degrees hotter than Wednesday.

LONG TERM...Friday night through Tuesday...After thunderstorms
move out of SW ID Friday evening, conditions through the extended
period remain dry and fairly consistent. High pressure stays over
the Great Basin and flow stays nearly zonal before it turns
southwesterly on Monday. Temperatures through the long-term will
measure in at right around normal under mostly sunny skies.
