NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
222 PM MDT Thursday Sep 18 2014 


..turning much warmer, dry and stable Saturday into early next 
week.... 


Discussion...the relatively deep layer of moisture on Thursday 
will transition into a cooler, but more shallow moist northwest 
flow tonight and Friday over north central Idaho and western 
Montana. This means the heavier shower threat will shift to the 
east and only leave a threat of very light showers or sprinkles. 
The northwest flow should help clear out much of the smoke and 
haze. The exception may be near the bigger fire areas of northeast 
Oregon and north central Idaho. 


A drier northwest flow should set up late Friday and Friday night 
resulting in clearing and a colder night. 


A strong ridge of high pressure should then build over the 
northern rockies Saturday into early next week. As this occurs, 
day time temperatures will quickly warm to well above normal. The 
down side is the atmosphere will become quite stable in the 
valleys with haze and smoke likely increasing. 


In the longer term, model guidance is not breaking down the 
ridge of high pressure over the northern rockies as quickly by 
mid next week. A transition to a wetter pattern still seems 
possible, but maybe delayed until late next week. 


&& 


Aviation...a moist southwest flow will transition to a 
west to northwest flow tonight into Friday. The deep instability 
and showers today will shift east and leaving a shallower moist 
layer in the lower atmosphere. Some mountain obscuration is possible, 
especially higher peaks tonight. 


&& 


Mso watches/warnings/advisories... 
Montana...none. 
Idaho...none.
