.DISCUSSION...Tonight through Saturday. Cloud cover working into
the western portions of the state this afternoon per satellite
imagery. Expect some destabilization to occur later this afternoon
into this evening for a threat of thunderstorms. Have kept slight
chance for thunder over most higher elevations, but HRRR
remarkably consistent today that the main threat will be from
convection developing over NV and shifting northeast into the
South Central Highlands, shifting north toward the Eastern Magic
Valley and weakening as the region continues to spread across the
Snake Plain. Isolated wind gusts up to 40 mph remain possible,
but do not expect severe gusts at this point. Upper trough lingers
Sunday, with a potential repeat in convection. Threat should be
limited to the eastern half of the forecast area, and mainly over
higher elevations. Upper ridge rebounds Monday through the
remainder of the week, with center of upper high located over the
four corners region. This continues to be a favorable pattern for
moisture to work north through the Great Basin, and the threat for
afternoon dry thunderstorms continues each day especially mid
week and beyond. It will be difficult to pin down the location for
development, so made very little change to expected precip
chances later in the week. Otherwise, the impact concern this week
remains with the increased temperatures, especially Tuesday and
beyond. So far, Thursday and Friday appear to be the hottest of
the week with temps likely approaching triple digits in many lower
elevations. Warmer overnight lows could exasperate conditions,
especially for people sensitive to increased heat. Cloud cover
from thunderstorms may be a mitigating factor, but this will be a
potential threat to keep an eye on as we move toward mid week. DMH

.AVIATION...A weak storm crosses the state in the next 24 hours,
spawning a few storms here, there and yonder over the mountains. At
the moment, KSUN and KDIJ would stand to be the most impacted. KIDA,
KPIH and KBYI COULD see impacts if storms happen to wander across
the Plain or adjacent terrain. Little rain and gusty winds over
25kts can be expected IF a cell passes over a given airport.  Keyes

.FIRE WEATHER...A weak storm crosses the state in the next 24 hours,
kicking off isolated dry storms over the mountains. Right now, the
Snake Plain looks dry BUT outflow (30+mph) from storms could move
out into the Plain and produce strong winds or even try to kick off
a storm or 2. The rest of next week should be very warm with low
humidities with very strong high pressure building across the
Rockies. Highs by midweek will be pushing 95-100 at lower elevations
and 75-85 in the mountains. Humidities will drop to 10-20% for the
Snake Plain and other low valleys and upper teens to mid 20s at
higher elevations. We will see inversions at night so mid/upper
slopes will remain quite dry. We WILL NOT be storm free though it
appears. Limited monsoon moisture works around the ridge for
possible isolated (and dry) storms over higher terrain.  It will be
hard to pinpoint which ranges will see storms each day at the
moment, but the possibility is there each day. Keyes

.HYDROLOGY...Rivers across East Idaho have shown a definite
downward trend over the past week with peak flows now likely
behind us. Some lingering issues remain at a few locations,
however. It remains to be seen how much impact the hot
temperatures this week will have on the rivers. Some increase is
expected in the basins of the Tetons, the Big Lost and in the
Central Mountains by later in the week. DMH
