Short term Tonight through Saturday.

Big impact through Thursday will be the wind as well as much
colder temperatures Thursday through Saturday. Many mountain
locations will see near freezing or slightly below freezing low
temperatures Thursday and Friday night. Wind advisories remain in
effect for much of the region both this afternoon and evening
through 9 pm and Thursday afternoon and evening from noon through
9 pm. Will have isolated to scattered showers and thunderstorms
this evening in the island park area which will end overnight.

Showers and thunderstorms Thursday through Saturday will be mainly
in the central mountains and easter mountain areas with snow
levels generally ranging from 6 to 8 thousand feet through the
period. Precipitation amounts are expected to remain light for the
next three days. Winds will die down considerably as well on
Friday. High temperatures are expected to be in the 10 to 20
degree below normal range through Saturday as well.

Gk

Long term Friday night through next Wednesday. Overall trend in
the extended will be moderating temperatures as a cold upper low
initially centered over montana lifts into canada while weakening.

In the process, zonal west-to-east flow will become established over
our region, and this will gradually transition to southwest flow by
early next week. This transition will take place as a strong area of
low pressure takes shape off of the washington and oregon coasts.

This pattern will likely bring a return to seasonable temperatures,
with some potential for above-average temperatures by the middle of
next week. Another commonality of this flow regime is the potential
for shower and thunderstorm activity, as individual disturbances
will pass through the region in the broad SW flow. We're maintaining
shower and thunderstorm activity Monday through Wednesday,
especially in higher-terrain areas. A few strong storms may even be
possible given the favorable flow regime. Ad

Aviation
Main impact both today and Thursday will be high winds. Will have
sustained 20 to 30 knot winds this afternoon and early evening at
ida and pih with gusts of 35 to 40 knots. Expect the same thing
Thursday afternoon and evening. Should die down a bit overnight to
sustained 10 to 15 knots and gusts up to 25 knots. Speeds will be a
bit less at byi, dij and Sun but still expect sustained close to 20
knots this afternoon as well as Thursday afternoon with gusts 30
to 40 knots.

Fire weather Primary fire weather impacts consist of low relative
humidity values combined with critical wind speeds this evening,
windy conditions again Thursday afternoon and early evening followed
by an unseasonably cool period Thursday through Saturday. A strong
cold front will plow across SE idaho this evening, promoting winds
of 25 to 35 mph with gusts around 45 mph for zones 425 and 410
through this evening, with the potential for higher gusts. Combined
with near-critical minimum relative humidity values of around 15
percent this evening across 425, near-critical fire weather
conditions will be in place. The only limiting factor would be near-
average live fuel moistures, but per the gacc fine fuels are
approaching critical moisture values across 425. Elsewhere, breezy
conditions will be found with near-critical winds. Isoalted
thunderstorms are expected this evening across 411 and far northern
portions of 410. For Thursday, a second cold front will sweep
through the region, promoting winds very similar to today, perhaps
even a couple of mph stronger. The same areas will experience these
winds on Thursday, with strong winds expanding into zones 427 and
413. W SW winds of 25 to 35 mph with gusts around 45 mph will be
common, with a few higher gusts not out of the question. Showers
along with isolated thunderstorms will be possible Thursday
afternoon and evening, mainly across northern portions of 476, 410
and all of 411, with a some activity possible across eastern
portions of 411 and 413 as well.

Temperatures Thursday through Saturday will be 15 to 20 degrees
below average for mid-june. Additional shower and thunderstorm
activity will be possible for most areas Friday afternoon and early
evening as well. Shower and thunderstorm activity Saturday looks to
be similar in timing and coverage to Thursday. Temperatures are
forecast to rebound to climatological averages by Monday with
continued warming and drying through the middle of next week.

Isolated showers and thunderstorms will be possible each day,
especially in higher terrain. Ad

Hydrology The flood advisory remains in place for the big wood
river at hailey with the stage below flood stage but remaining in
action stage for a few more days.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
