Discussion One more hot day is in the forecast across SE idaho
today, with temperatures likely challenging record highs once
again. Record highs for today range from 88 at stanley to 98 at
burley. A seasonably strong low pressure trough and associated
cold front is then forecast to sweep across SE idaho Wednesday
night, bringing a round of gusty winds along behind the front
followed by a roughly 10 degree temperature drop for Thursday.

Forecast guidance is in good agreement with regards to timing of
the cold front, with all indications suggesting the front at
midnight tonight will stretch from challis SW towards mountain
home, with the front reaching a Sun valley to pocatello line
around 3am and finally crossing into wyoming around 6am. The front
will of course pass through the snake plain before clearing the
central mountains, as the mountains will act as a barrier slowing
the front's progression. All high-resolution guidance suggests the
development of isolated showers and thunderstorms across the
central mountains (mainly along north of a mackay to ketchum line)
developing between 4 and 6 pm continuing through about midnight.

Guidance then indicates a band of showers in the post-frontal
airmass, but think the column will be too try to support rainfall
for all but the central mountains and montana divide region.

Precipitation amounts will overall be light, mainly under 0.10"
with any of this activity. Breezy southwest to west winds will
continue through the day Thursday behind the front, mainly in the
15-25 mph range across the snake plain, and therefore a lake wind
advisory may be needed. Given the excellent forecast model
agreement, confidence in the forecast details is fairly high.

Looking ahead, guidance is in good agreement in their depiction of
the development and maintenance of a broad westerly flow regime
across our region from Thursday through Monday, and this should
result in seasonable temperatures and breezy conditions each day.

This pattern may require lake wind advisories and possibly even a
wind advisory. At this time, the best chance for a wind advisory
may be Sunday, as guidance indicates the potential for widespread
15-25 mph winds with gusts to 35 mph across the snake plain. A
ridge of high pressure is then advertised to develop across the
northern rockies early next week, with decreasing winds and rising
temperatures. At this time, we don't see any day with
precipitation chances, although a sneaky shower or storm could be
possible across the island park region early next week. Ad

Aviation Vfr conditions continue at all east idaho terminals. There
is a chance of a thunderstorm or two across the central mountains
this evening, but expect activity to remain north of ksun so will
keep terminal dry for now. Winds are expected to pick up to
around 15kts sustained late tonight as generally dry cold front
approaches passes the region. Dmh

Fire weather Very dry and warm conditions continue today, though
there is a possibility of another thunderstorm or two to develop
over the northern portions of zones 475 and 476 again this
evening. High haines is also forecast most areas with the hot dry
air mass. Cold frontal passage tonight and early Thursday will
bring temperatures down slightly from the near-records today, but
precipitation will be limited to areas along the montana border.

Humidities will increase to above critical levels most areas due
to the cooler temperatures, but near critical will be possible
across portions of zone 410. Stronger winds are expected as well
behind the front, so a headline may be necessary for the daytime
Thursday depending on how the humidities and winds line up for the
day. Temperatures remain stable moving into Friday, with less
breezy winds but continued dry. Dry westerly flow aloft will be a
contributing factor to breezy winds continuing through the
weekend. Dmh

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.
