219 pm mst Wed feb 20 2019

Short term Tonight through Friday... Ongoing winter storm
continue through Thursday morning as the upper level low moves
across southeast oregon. As of 1200 pm mst, the boise airport has
recorded 3.9 inches of snow for this event. A band of snow over
much of southwest idaho today will continue to move east as the
upper level low moves over southeast oregon this evening. As the
low continues southward tonight, the snow will decrease, except
for the owyhees and idaho highlands along the nevada border where
the snow showers are expected to persist due to the closer
proximity to the upper low. Latest models have shown these snow
showers to be further north across western magic valley and
eastern parts of the upper treasure valley. Thus, have extended
the winter weather advisory for the western magic valley along
with the southwest highlands and southern twin falls county
through Thursday morning. A weak upper ridge will bring dry
weather to the area Thursday night through Friday. Fresh snow on
the ground and mostly clear skies Friday morning will allow
temperatures to drop into the teens in the valley and near zero in
the mountains. Temperatures overall will remain below normal.

Long term Friday night through Monday... The latest models show
the next upper level trough moving south from northwest canada and
stalling over british columbia. South of the trough, a strong and
moist westerly flow aloft from the pacific over southeast oregon and
southwest idaho will bring breezy and milder weather with widespread
precipitation. However, model blends are still showing below normal
temperatures, with snow levels near the valley floors. Snowfall
amounts Saturday through Sunday are expected to be under an inch in
the lower valleys, with 8 to 12 inches in the central idaho
mountains above 6000 feet.

Monday night through Wednesday night... Windy, cold and showery
are the conditions expected to start the period across the region
as combined tropical and north pacific moisture is coaxed into the
area. Although the strongest moisture push is expected at the
start of the period, showers will remain in the picture entirely.

Look for snow showers to blanket the area through half the period,
afterwards gradually switching to a mix of snow and rain mostly
in the valleys. This attributed to higher snow levels being pushed
northward into the area from the south. Also, expect higher
amounts across the mountains, especially in the north. Showers
(intensity and coverage) should slowly diminish as the period
progresses. High temperatures are expected to measure in around 7
degrees below normal while drop down around within a few degrees
lower than normal.

Aviation Scattered MVFR ifr conditions in snow showers and areas
of mountain obscuration through tonight. Show showers mainly ending
at lower elevations on Thursday. Surface winds west to northwest 5-
10 kts. Winds aloft at 10k feet msl northwest to north 10-15 kts
becoming northeast to east 10-15 kts on Thursday.

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.
