Discussion Mostly sunny day today in the wake of a shortwave
passage earlier this morning. Breezy surface winds mainly east of
mountain home will diminish this afternoon. Next moist upper
level trough and cold front are quickly approaching the pacific
northwest coast today. Clouds associated with this system will
reach southeast oregon early this afternoon. The cold front with
showers will reach southeast oregon around 03z tonight and moves
east into southwest idaho late tonight/early Wednesday morning.

Wednesday still looks to be very wet with the bulk of moisture
moving over the intermountain west. Updated pops, QPF and wx for
tonight through Wednesday morning. Update will be out shortly.

Aviation WidespreadVFR with scattered-broken mid and high level
clouds. Isolated ifr ceilings in the west central mountains
(including kmyl) will improve toVFR by 18z. Scattered MVFR showers
will continue in the west central and boise mountains through this
afternoon. Surface winds: west-northwest 5-15 kts, except 15-25 kts
from a kmuo to kjer/ktwf corridor. Winds aloft near 10k ft msl: west-
northwest 10-20 kts.

Prev discussion
Short term... Today through Wednesday... Showers continue to move
through the central idaho this morning. Satellite is demonstrating
drier air, associated with a diving shortwave, moving into
eastern oregon which will help to keep shower activity minimal
through the afternoon. A few showers across the west- central and
boise mountains. Clearing expected with the drier air, allowing
temperatures to warm slightly. The moisture reprieve will be
brief, with the next pacific system moving inland and into eastern
oregon by late Tuesday evening. A stronger secondary push of
moisture will move inland after midnight, creating widespread
showers by early Wednesday morning. Models in good agreement that the
upcoming system will be rather potent in regards to moisture with
around a half inch possible in the valleys and close to 1 inch in
the mountains by Wednesday evening. Snow levels remain between
5000 and 6000 ft msl, keeping snow and a rain-snow mix possible
through Wednesday. Colder temperatures expected due to the passage
of a cold front. Additionally, passage of this front will aid in
creating instability around the or/id border, with some
thunderstorms possible. Showers and thunderstorms will then
continue through Wednesday afternoon.

Long term... Wednesday night through Monday... As Wednesday's
system exits the region, continued moisture within a northwesterly
flow aloft will prevail, though the focus of precipitation will
generally be over the higher terrain. Thicknesses drop across the
region Thursday and into Friday for temperatures 10-15 degrees below
normal and a slight chance of morning snow down to valley floors.

Qpf amounts will be low however, and no accumulation is expected. A
shortwave ridge will push into the region late Friday, bringing a
brief period of drying and warming conditions through late Sunday
before the ridge breaks down and a moist northwest flow aloft sets
in once again. Temperatures will be within 5-10 degrees of normal
beginning Saturday through the end of the period with low 60s
expected across the snake river plain over the weekend.

Or... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
