Discussion A low pressure system continues to move across
north-central idaho this morning spreading light to moderate snow
across the region. An additional 1 to 3 inches are expected
through the day today, with isolated higher amounts possible,
especially the higher in elevation you are. Winter weather
advisories and warnings remain in place at this time.

Light snow has diminished in several places across western
montana, except along the continental divide. A secondary surge of
moisture is forecast to move over the area later this morning,
that will bring another round of light snow, particularly along
and south of the i-90 corridor. Snow will become more showery in
nature this afternoon, that could produce intense snow rates for a
short period of time as the showers move overhead. Around an inch
or 2 of additional snow is possible through the day. If any
particular location is hit by one of these showers, slightly
higher amounts are possible. Winter weather advisories remain in
place across western montana through the day as well.

Later this evening and overnight, a modified arctic airmass will
begin to spill over the continental divide. Gusty east-northeast
winds will begin to increase along highway 2 from marias pass to
kalispell, as well as i-90 and highway 12 200 from the divide west to
missoula as the arctic air moves in. It is not expected to be as
strong as the events we have experienced earlier in the month. But
localized blowing snow will be possible in the areas mentioned
above.

Snow will be tapering off overnight tonight and through the day
on Thursday, however lingering snow showers will remain in the
forecast through this period.

Light snow will develop again across northwest montana on Friday
and then spread to most areas by Saturday. Another surge of arctic
air is expected Saturday night into Sunday bringing more north to
east winds to western montana while snow is possible for central
idaho.

Ensemble model guidance point to continued unsettled weather into
next week with colder than normal temperatures. Besides periods of
light snow mid-week, there could be a decent overrunning heavy
snow event with subtropical influences by the end of the month,
but it is a little too early to hang your hat on anything
substantial.

Aviation Light snow will continue across north-central idaho
and western montana today. A low pressure center, that is
forecast to pass through north-central idaho, will focus the
heaviest snow near the triple point of wa or id. Snow showers will
continue off and on this afternoon with mountain obscuration and
lower visibility at times, especially near the divide as a surge
of cold air moves west after 21 0000z. Breezy easterly winds will
develop during this time and continue Wednesday night. Snow
showers will become more isolated on Thursday with some
improvement with ceilings and visibility.

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.
