Area Forecast Discussion
National Weather Service Missoula MT
852 AM MDT Mon Oct 28 2013

...Updated to upgrade advisory to winter storm warning for Butte to
Anaconda into this afternoon...

.DISCUSSION...Light to moderate snow, areas of strong winds, areas
of blowing snow and low wind chills are now creating a very
hazardous winter driving conditions, especially over mountain
passes along the Continental Divide and from Butte to Anaconda.
Travelers using Interstate 90 will experience quite variable
driving conditions with relatively little snow in Deerlodge to
blowing snow and ice/snow covered roads especially east of Warm
Springs. Visibilities will be quite low at times. The snow should
decrease in the afternoon, but the very slick and variable/sudden
change in road conditions should continue through the afternoon.
The winter conditions are no longer just an inconvenience, but are
quite hazardous.

&&

.AVIATION...Gusty northeast to east winds are beginning to decrease
slightly this morning, and are expected to continue this trend through
the day. The strongest winds this morning will be most
likely to occur at KMSO, where gusts to 40 kts will still be
possible through 28/1800z. The high terrain and locations along
the divide will have a combination of snow, wind, and obscured
terrain through the day today. The most impacted airfields due to
snow and wind potential will be KBTM and KSMN, mainly through
28/1800z. KSMN may see another round of light snow this evening
between 29/0000z and 29/0600z.

&&

.PREV DISCUSSION... /ISSUED 353 AM MDT Mon Oct 28 2013/

DISCUSSION...A cold arctic airmass will continue to settle over
western Montana and north-central Idaho today. The main impact
from this system will continue to be gusty northeast to east winds.
Overall, wind speeds will be on the decrease through the morning,
however gusts over 40 mph will still be possible. The secondary
impact today will be snow, mainly in the higher terrain along the
Continental Divide. While snow amounts are expected to remain
fairly low, blowing snow will lower visibility at times. Travel
over mountain passes such as Marias Pass on Highway 2, MacDonald
Pass on Highway 12 and Homestake Pass on I-90 could be difficult
due to periods of low visibility and slick road conditions as snow
and ice accumulates on road surfaces. Most valley locations have
seen very little in the way of snow due to downsloping effects
from the wind. This trend is largely expected to continue, with
the exception of the high valleys of southwest Montana
(Butte/Anaconda/Georgetown Lake) and across Lemhi County. The main
impact from snow in these areas will be slick road conditions.
Moisture may freeze on road surfaces as temperatures continue to
drop, causing patchy areas of ice. Numerous wind and winter
weather highlights remain in place. Please see
www.weather.gov/missoula for further details.

Cold air will funnel into the area today, causing temperatures to
stay steady, or even drop, through the day. The combination of
wind and cold air will make temperatures feel more like the mid
teens and low 20s. As skies clear out tonight and winds continue
to relax, temperatures will plummet both Tuesday and Wednesday
mornings.

Cooler temperatures will stick around through much of the week,
with a brief respite in precipitation and cloud cover for
Wednesday. This will be short lived however as northwest flow sets
up by Thursday, which will lead to rain and snow showers across
the region. By Saturday evening, forecast models are in good agreement
with bringing another low pressure system and cold front through
the region. This next front comes off the Pacific, so it will not
be as cold as the current system over the region. However another
round of mountain pass snows will be possible.

AVIATION...Gusty northeast to east winds are beginning to decrease
slightly this morning, and are expected to continue this trend through
the day. The strongest winds this morning will be most
likely to occur at KMSO, where gusts to 40 kts will still be
possible through 28/1800z. The high terrain and locations along
the divide will have a combination of snow, wind, and obscured
terrain through the day today. The most impacted airfields due to
snow and wind potential will be KBTM and KSMN, mainly through
28/1800z. KSMN may see another round of light snow this evening
between 29/0000z and 29/0600z.
