.DISCUSSION...Tonight through Friday. Upper ridge over Idaho
shifts east into Saturday as Pacific trough shifts inland.
Afternoon and evening mainly dry convection looks possible
Saturday and Sunday. Depending on timing of the dynamics aloft,
there is a small chance convection could linger overnight Saturday
night. Upper ridge rebounds across the region Monday, with center
of High setting up directly over 4-corners region. This pattern is
favorable for moisture to work north through the Great Basin, and
both GFS and ECMWF are hinting at this taking place later this
week. Thus have nudged precip chances to earn slight chance
mention of thunder over higher terrain. Otherwise, expect warming
temperatures through the week, approaching triple digits,
exceeding in a few locations by Wednesday. Have kept current
forecast hovering at or just below raw numerical guidance, but at
the higher end of current guidance spread. DMH

.AVIATION...With high pressure ridging in place, expect dry
conditions and overall light winds today into tomorrow. A weak
system moves through late Saturday into Sunday bringing breezy winds
and vicinity showers and thunderstorms. Wyatt

&&

.FIRE WEATHER...With high pressure ridging in place, expect dry
conditions and overall light winds today into tomorrow. A Pacific
disturbance will move onshore through the ridge late Saturday
through Sunday bringing isolated to scattered showers and
thunderstorms. Strong high pressure ridging builds back in by mid-
week resulting in much warmer temperatures. Monsoonal moisture may
rotate north across the Western edges of our area as early as late
Wednesday or early Thursday next week bringing isolated showers and
thunderstorms. Wyatt

&&

.HYDROLOGY...With cooler temperatures recently, river levels in most
areas, particularly those not directly impacted by reservoir
releases, will see a gradual decrease over the next few days. For
those areas with remaining high elevation snow, which is the Central
Mountains, Big Lost and the Tetons, they will likely see increase
flows next week after a return of very warm temperatures this
weekend and, particularly, next week. Wyatt
