Discussion A warm front is moving northeast through the area
this evening. This will result in the snow level moving higher,
ending up ranging from 7500 feet in the north to over 9000 feet in
the south by daybreak Sunday. At the same time, the vast majority
of the precipitation will transition to the northern half of the
cwa - roughly north of a line from burns to ontario to fairfield.

Burns is experiencing a wet snow as of 7 pm pdt, but that should
be changing over to rain soon. No changes to the forecast at this
time.

Aviation Widespread precipitation will continue across southwest
idaho through late tonight. Scattered MVFR conditions with the
heavier bands. Local ifr lifr conditions in snow above 5k ft msl.

Snow levels rising to 6k-9k ft msl by Sunday morning. Precipitation
ending from west to east except in the mountains of baker county
oregon and central idaho after 06z. Surface winds southeast to
southwest 10-20 kts. Winds aloft at 10k ft msl west 35-50 kts.

Sunday outlook... Precipitation continuing over the mountains of
baker county oregon and the west central idaho and boise mountains,
with local MVFR conditions and areas of mountain obscuration. Snow
levels 7k-9k ft msl in the morning rising to 8k-10k ft msl in the
afternoon, highest in southeast oregon and along the nevada border.

Patchy fog could develop in sheltered valleys Sunday morning.

Surface winds se-sw 5-15kt.

Prev discussion
Short term... Pcpn has been slow to spread east today but at
2 pm mdt the leading edge was across the or id border, with
light snow at mccall, id, and light rain at ontario and rome,
or. Radar shows echoes out ahead but this is virga. Snow
fell all morning at burns, or, with temp near 32f. Wet snow
accumulated a couple inches there but web cams showed melting
early this afternoon.

Models agree that warm-frontal rain and snow will move into
western idaho this afternoon and evening, then retreat northward
in idaho overnight. Models look a little too heavy on QPF tonight.

Rain and snow will continue through the night and Sunday north of
the snake basin. The treasure valley will be on the southern
fringe Sunday morning. Snow level near 4000 feet msl north to
5000 feet msl south this evening will rise to 7500 feet north
and 9000 feet south by early Sunday morning. Snow accumulation
will be light below 5000 feet msl and roads should be wet or at
worst slushy. Low temps will range from near 30 in the mountains
to near 40 in the lower valleys. Sunday will be warmer than today
with highs 45 to 55 in the mountains and 55 to 65 in the lower
valleys, warmest in southern malheur county. Chance of light
rain will continue Sunday night in central idaho, but other
areas will become drier. Lows 30 to 40. Monday looks mostly
sunny under dry northwesterly flow aloft, with high temps in
the 50s in the mountains, and 60 to 65 in the lower valleys.

Southwest winds tonight 15 to 25 mph in eastern oregon and
southeast 10 to 15 mph in idaho. Light south or southwest winds
in all areas Sunday, and light west winds Monday.

Long term... Monday night through Saturday... A high amplitude upper
level ridge over the western u.S. Will maintain mostly clear skies
Monday night through Tuesday night. The ridge will relocate off the
west coast on Wednesday. This will allow strong northwest flow aloft
to bring an upper level trough over north idaho and montana
Wednesday night, with scattered rain and snow showers as far west as
the mountains of central idaho and baker county oregon. In idaho
isolated showers are possible as far south as the nevada border. The
system will be followed by clearing skies and cooler temperatures
Thursday and Friday. Temperatures will be slightly above normal
Monday night through Wednesday night, and around 5 degrees below
normal Thursday through Friday night. A slow warming trend will
begin on Saturday as the ridge shifts east over the coast.

Boi watches warnings advisories
Id... None.

Or... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
