NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
252 PM MDT Friday Sep 4 2015 


..cold & wet Labor Day weekend with snow above 6500ft... 


Discussion...models have changed very little over the past 12 
hours, so only minor adjustments were made with an emphasis placed 
on refining the details of heaviest precipitation placement along 
with the threat of mountain snow. 


First, let's talk snow! We issued a Winter Weather Advisory above 
6500ft for the higher terrain along the Continental Divide. This 
is primarily for those with plans to adventure in the mountains 
and back country this weekend. But do anticipate accumulating snow 
at some more frequently traveled locales, such as: Logan Pass in 
Glacier National Park, Skalkaho Pass in the Sapphire mtns., 
Perhaps briefly over Lost Trail Pass in Lemhi county; Gilmore 
Summit and Williams Creek pass all will see the threat for 
accumulating snow. So those with travel or back country adventure 
plans in western Montana should be prepared to encounter winter- 
like conditions developing Saturday afternoon and persisting 
overnight into Sunday morning. 


As far as rain GOES, the forecast was adjusted somewhat to account 
for some subtle changes to the overall path of the upper level 
low. In general, the trend has now placed more precipitation 
across northwest Montana and especially along the Continental Divide 
(think bob Marshall wilderness & Glacier National park) while 
suggesting slightly lesser amounts falling over SW Montana and 
north central Idaho. So plan for cold, wet conditions this 
weekend, even if you don't plan to be in the high country. This 
storm system will be a significant rain maker for many locations 
and likely present a near death blow to many area wildfires. ~Iv 


Showery conditions will persist Sunday with the best chance for 
rain lingering across northwest Montana and along the Continental Divide. 
Showers will again linger on Monday as the main trough passes to 
the east and a weak shortwave arrives from the west. A general 
drying and warming trend is expected for the rest of next week 
with westerly flow to develop. High temperatures will return to 
near normal (mid 70s) for the second half of the week. 


&& 


Aviation...a narrow band of precipitation will continue to impact 
kbtm and ksmn causing low ceilings and reduced visibility. This 
band will shift off to the east. As the low pressure system moves 
into the area showers will increase in coverage tonight. All 
terminals will be impacted by low ceilings and periodic reduced 
visibility. Mountains and passes will be obscured much of the 
night due to the low clouds.
