Discussion Winter weather advisories and warnings are in
effect for multiple and various impacts across the northern
rockies. A strong winter storm is beginning to impact the region
with mountain snow over lookout pass. Snow will begin to pick up
in intensity and coverage across all of the region's mountain
passes late this afternoon and evening. However macdonald and
homestake passes will escape with minimal snowfall and impacts.
Expect moderate to heavy snow at times with some occasional
snowfall rates of 1 inch per hour. Lower valleys in central idaho
will see a mix of rain snow and freezing rain this evening.
For locations in and around grangeville, idaho. We are expecting
light snow accumulations, though the biggest threat will be strong
gusty southerly winds that have the potential to gust up to 55
mph. The southerly cross winds along highway 95 from grangeville
west to cottonwood, could become hazardous to high profile
vehicles, and visibility due to blowing snow. Current forecast
have the strongest winds from sunset this evening to sunrise
Snowfall is expected in the valleys of western montana later
tonight through the Wednesday morning commute. Snowfall amounts
aren't expected to be more than 1-3" however some strong snow bands
are expected to materialize late tonight and Wednesday morning and
bring locally moderate to heavy snow. Strong winds in and around the
snow bands could produce blowing snow impacting visibilities for
travelers. Some areas of concern for travelers will be the S curves
between missoula and lolo as well as the i-90 corridor from clinton
to butte. Sporadic power outages are possible due to winds gusting
up to 40 mph, with isolated higher winds in the bitterroot valley.
The stronger winds are expected to arrive around midnight tonight,
and continue until mid morning tomorrow.
The winds will gradually diminish from west to east during the day
on Wednesday. Gusty winds up to 40 to 45 mph will continue along
i-90 from dearlodge to butte through most of the day.
The remainder of this week into next week will bring periods of
unsettled weather, aka wind and mountain snow, as several weather
disturbances are expected to move in and around the vicinity of
the northern rockies. Temperatures will be at or above normal
through next week. In fact, the missoula and bitterroot valleys
can expect high temperatures in the mid and possibly upper 40s
Friday. Overnight lows will be in the lower to mid 20s through|
next week. No major cold outbreaks are expected through the middle
of next week.
Aviation High clouds have moved in from the west and winds are
increasing from the south and southwest. Overnight a pacific
weather system will affect the entire forecast area. Bringing
light snow to the valleys and heavy snow to mountain passes of the
idaho and montana line. Winds in the bitterroot and missoula
valleys will increase to 15 to 25 gusting to 40 kts affecting mso

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.
