NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
244 PM MDT Tuesday Jul 7 2015 


Discussion...showers brought around a quarter of an inch of rain 
to portions of northwest Montana this morning. The current 
pressure analysis reveals a 1,020 millibar high pressure system 
centered over cutbank, Montana. This has brought a northerly wind to 
much of western Montana with gusts to 30 mph being reported across 
portions of the mission and Missoula valleys. Also these northerly 
winds have brought more smoke to western Montana. Smoke is 
expected to linger for the next several days as wildfires in 
British Columbia and Washington continue. 


An upper level wave, as seen by the darkened area on water vapor 
imagery, will continue to track southward into western Montana 
through this evening. Those areas that warm up and recover from 
the cooler morning conditions will be able to see more shower and 
thunderstorm development this evening. High resolution models 
have hinted that some of these showers may coalesce into a frontal 
boundary that tracks southward early this evening. This could 
bring strong gusty winds to Flathead Lake and also to portions of 
Sanders and Mineral counties. Confidence is average to poor as 
these models have not been very consistent from run to run. Expect 
showers and thunderstorm activity to wane after midnight. 


Easterly breezes will continue on Wednesday while northwest 
Montana and portions of north-central Idaho will warm back up with 
drier conditions. The best chance for showers and a few 
thunderstorms will be across Clearwater and Lemhi counties in 
Idaho and across southern Ravalli County to Silver Bow County in 
Montana. 


Thursday, another round of thunderstorms associated with the 
southwest monsoon will stay mainly over central Idaho and 
southwest Montana. 


By Friday, a slow moving low pressure system off the California 
coast will interact with deep monsoon moisture from the 
southwestern U.S., Causing a surge of moisture into the northern 
rockies. Through the weekend, the low pressure system will get 
absorbed into a much stronger, deeper trough off the West Coast. 
The interactions of these systems with the monsoon moisture will 
cause very wet thunderstorms over much of central Idaho and 
western Montana through early next week. The timing and location 
of the heaviest rain each day remains uncertain, though models 
agree well that all the needed ingredients will be in place over 
the weekend. The most likely places to be the hardest hit by rain 
include central Idaho and Montana along and south of 
Interstate-90. 


&& 


Aviation...scattered showers and thunderstorms are possible at 
all area terminals this afternoon. Expect intermittent reductions 
in visibility in areas of heaviest thundershowers. Small hail is 
possible with a few of the thunderstorms especially across 
southwest Montana. Shower activity will diminish by later tonight. 
Breezy north to east winds will continue through Wednesday as 
Canadian high pressure lingers across central Montana. Some 
terminals, especially kmso and kgpi, will be affected by smoke 
from regional wildfires. 


&& 


Mso watches/warnings/advisories... 
Montana...red flag warning until 9 PM MDT this evening Flathead/Glacier 
park...Kootenai. 


Idaho...none.
