Area forecast discussion 
National Weather Service Missoula Montana 
355 am MDT sun may 19 2013 


Discussion...rain will once again be the predominant feature 
again today, with the most prominent coverage remaining along the 
Continental Divide this morning. Showers will then gradually shift 
westward, encompassing most of western Montana and central Idaho 
by this afternoon. The good news is: this should be the last round 
of rainfall we see today, with a break expected Monday and Tuesday 
under brief high pressure. Temperatures will remain cool today, 
but as drier conditions return on Monday and Tuesday, high temps 
will rebound into the 70s through Tuesday. Enjoy the warmth and 
reappearance of the sun, because rain, and many days of it, will 
once again return on Wednesday. 


Wednesday through Friday...forecast models continue to advertise 
the development of a deep low pressure system over the Pacific 
northwest. This low remains nearly stationary through the second 
half of next week and will present concerns to the northern rockies 
region. 


First, considerable moisture will be circulating around the low 
center. At the present time, the main targets are Glacier 
National Park and the bob Marshall wilderness areas, with moderate 
to heavy rainfall. Contributions from significant rainfall and 
accelerated snow melt due to warm temperatures poses a real threat 
for increased runoff and rising rivers and small streams levels 
across northwest Montana by the end of the week. 


Secondly, the atmosphere ahead of the low pressure system will be 
warm, moist, and unstable. Thunderstorms will be part of the 
forecast, but whether or not storms become severe is still in 
question. 


Finally, snow over lookout and Lolo mountain passes is a 
possibility and could be an impact to travel and recreational 
enthusiasts who are tempted to head into the mountains across the 
Idaho Panhandle and adjacent Montana Mountains. 




&& 


Aviation...the atmosphere remains moist and quite unstable and 
showers will redevelop during the day as temperatures warm at the 
surface. There will be some precipitation moving across the 
Continental Divide and into west-central Montana this morning. Mountains 
will obscured at times in clouds and precipitation, especially 
during the afternoon and evening hours. All airfields will be 
impacted by showers and lower ceilings from time to time. Shower 
activity will decrease once the sun dips below the horizon. 
Overall conditions will be improving tonight.
