Severe Weather Alert Descriptions

 Winter Weather Advisory  Statement as of 8:47 PM MDT on August 22, 2014


... Winter Weather Advisory remains in effect until noon MDT
Saturday above 6500 feet...

A Winter Weather Advisory above 6500 feet remains in effect until
noon MDT Saturday.

* Impacts/timing: an unseasonably cold Canadian air mass will
descend upon the Continental Divide overnight... with air
temperatures steadily cooling through Saturday. At the same time
precipitation will steadily intensify along the Continental
Divide tonight and continue at a heavy rate through Saturday
morning. This combination will drive the snow level down to
between 6500 and 7000 feet.

* Additional impacts: persons hiking... traveling or recreating
between 5000 feet and 6500 feet should be prepared for a very
cold rain... which when combined with winds of 10 to 20 mph and
air temperatures in the 30s and 40s could heighten hypothermia
concerns.

* Snow accumulations: 1 to 3 inches between 6500 feet and 7000
feet... including Logan Pass. 2 to 5 inches above 7000 feet.
Locally higher amounts of up to 8 inches are possible on the
highest peaks of the bob Marshall wilderness.

Precautionary/preparedness actions...

A Winter Weather Advisory for snow means that periods of snow
will cause primarily travel difficulties. In this case the most
significant impacts will be felt to those hiking and visiting the
higher terrain trails and usfs roads. Be prepared for snow
covered roads and limited visibilities... and use caution while
driving.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
304 PM MDT Fri Aug 22 2014 


..accumulating mountain snow above 6500ft along Continental Divide... 


..Potential for patchy morning frost Tuesday and Wednesday next week... 


Discussion...an area of widespread showers and thunderstorms are 
starting to fire across the southern Bitterroot and Clearwater 
Mountains this hour. This activity is forming near a developing 
mid-level circulation and will very slowly move to the northeast 
before gradually curving to the northwest. Severe weather is 
unlikely today, given the cool atmosphere and low cloud tops, so 
heavy rainfall will be the key threat. This will especially be the 
case near wildfire burn areas and remain closely watched through the 
evening. For further details regarding the flooding potential over 
the next 24 hours and the currently issued Flood Watch, please see 
the below hydrology discussion. 


An intensification of precipitation is expected tonight as the mid 
level circulation further develops and strengthens. The focus for 
this precipitation will be two fold. The developing late tonight 
across the southern Bitterroot/Sapphire mtns eastward through the 
Anaconda- pinter wilderness towards Butte. Locations such as 
Hamilton, philibsburg, Georgetown Lake, Sula, Lost Trail Pass, 
Butte and perhaps even as far north as Stevensville will 
experience a period of heavy rainfall. 


The next area of focused precipitation will fall along the 
Continental Divide from the Canadian border southward to around 
MacDonald Pass. This precipitation will be fed by an extremely 
moist atmosphere across the upper plains states and further 
accentuated by strong easterly winds producing up slope flow along 
the leeward side of The Divide. But descending cold air from Canada 
will add an additional element of complexity to the forecast and 
result in the snow level lowering to around 6500ft under this area 
of heavy precipitation. Thus a Winter Weather Advisory will go 
into effect for Glacier National Park and the bob Marshall 
wilderness from 10pm tonight through midday Saturday. Generally 
speaking, 1 to 3 inches are expected between 6500 and 7000ft with 
2 to 5 inches possible above 7000ft. The highest peaks could 
potentially see upwards of 8 inches under extremely heavy 
precipitation cores by Saturday morning. Those with plans to 
adventure in Glacier National Park or other trails along The 
Divide should plan for cold, wet conditions at all elevations with 
snow expected across the higher terrain above 6500ft. 


Conditions will begin to improve throughout Saturday from west to 
east with most precipitation completed by Sunday morning, 
revealing a cool, but pleasant Sunday. 


Next week will start out with another trough over the northern 
rockies which should increase the shower chances again and keep 
temps slightly below normal. High pressure then appears to build 
midweek with cold mornings and warm dry afternoons. This lull in 
the active fall pattern is transient as computer models continue 
to show even colder systems coming down from the Bering Sea into 
the Pacific northwest for Labor Day weekend into the first week of 
September. /Ss 


&& 


Hydrology...a Flood Watch remains in effect through midday tomorrow 
given the potential for convective redevelopment overnight across 
Clearwater, Ravalli, Missoula, Lemhi, Granite, Deer Lodge and 
Silver Bow County. Some minor urban flooding (ponding of water on 
roads) will be possible with some burn areas being threatened. 
Meanwhile farther north convective precipitation is expected to 
gradually transition to more light, stratiform rainfall by late 
this evening. This combined with a slowly falling snow level 
overnight will inhibit the potential for flooding and thus the 
Flood Watch for Flathead, Lake and Powell County will be in effect 
till 10pm. There may be some minor issues with stream decending 
from The Divide should the maximum rate of precipitation become 
incredibly intense. However these concerns should remain limited 
to the east side of The Divide. 


Aviation...thunderstorms are starting to develop along the 
terrain of southwest Montana and north central Idaho. Thunderstorm 
coverage will continue to increase through the afternoon and is 
expected to transition into steady precipitation tonight. Aviation 
terminals kbtm, kmso and ksmn will have the best chance to see a 
thunderstorm this afternoon with the main impacts being brief heavy 
rain, small hail and gusty winds. Ceilings will also significantly 
lower and visibility may go below 3 miles under intense rainfall. 
Kgpi will see some passing showers this afternoon but is expected 
to see drier conditions as breezy northeasterly winds move in this 
evening. For tonight, expect steady moderate precipitation at 
kbtm, ksmn and kmso. Ceilings and visibility will steadily drop 
through Saturday morning which may cause travel delays.

Montana...Lake Wind Advisory until 9 PM MDT this evening for Flathead Lake 
in the Flathead/mission valleys.

region...West Glacier region.
