.SHORT TERM...Tonight through Thursday night...A few
isolated thunderstorms are possible across portions of Harney
County on the far western side of our forecast area early this
evening. Isolated thunderstorms are also possible in south
central Idaho, mainly south of the Twin Falls area through early
evening as well, but will dissipate after sunset. Tomorrow will
be another hot day, though not quit as hot as it is today. The
atmosphere will become quite unstable tomorrow afternoon and
there will be increasing mid-level moisture which will cause
a 20 to 30 percent chance of thunderstorms across southwestern
Idaho and southeastern Oregon. However, the lower portion of the
atmosphere will remain rather dry which will cause much of the
rain associated with these thunderstorms to evaporate before
reaching the ground. Still...up to a tenth of an inch or rain
is possible in the core of the strongest storms. Expect gusty
winds in the vicinity of showers, thunderstorms and
virga...diminishing after sunset. Another round of scattered
showers and thunderstorms is expected on Thursday afternoon with
the passage of weak cold front.

.LONG TERM...Friday through Tuesday...Expect mostly clear skies, dry
weather with temperatures near normal through the 4th of July
holiday and on Saturday. A significant warming trend will begin
on Sunday with hot and dry weather returning early next week.
