NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
431 am MDT Monday Aug 3 2015 


Discussion...one more day of well above normal temperatures and 
smokey skies before a surge of monsoonal moisture Ushers in a 
pattern change. This afternoon, clouds will increase with 
scattered thunderstorms developing in north central Idaho and 
pushing northward through the evening. These will remain primarily 
south of the I-90 corridor, but a few storms could also develop 
along the Continental Divide. Gusty winds and lightning will be 
the main threat with these storms. Overnight into Tuesday morning, 
a weak front will bring showers and breezy winds through the rest 
of northwest Montana. 


Tuesday will be cooler with western Montana back to more seasonal 
temperatures. North central Idaho will also cool a few degrees, 
but not as drastically as western Montana. Scattered afternoon 
thunderstorms with again be possible over much of western Montana. 


On Wednesday, another shot of moisture will bring more widespread 
showers and thunderstorms over southwest Montana and north central 
Idaho. Drier air will limit showers for northwest Montana. 


Relatively dry westerly flow aloft will develop over the northern 
rockies Thursday through at least midday Saturday. Daytime 
temperatures will trend upward somewhat. Breezy afternoons are 
probably the most significant weather impact for this time. 


Long-range models suggest another surge of moisture over the 
northern rockies midday Saturday through the remainder of the next 
weekend, with showers and thunderstorms plausible. Northwest 
Montana appears to, once again, be largely missed by this next 
opportunity for precipitation over the region. 


&& 


Aviation....light terrain driven winds will be present through 
the morning, with wildfire smoke continuing to cause minor 
reductions in visibility at times. By the afternoon, scattered 
mid- level clouds will begin making their way north over southwest 
Montana and lehmi County as moisture increases. Smoke 
concentrations will begin to dissipate during this transition. 
Ksmn could see some vicinity showers and thunderstorms during the 
afternoon, with these storms spreading north to kbtm by the 
evening. As a front moves through overnight into Tuesday morning, 
kmso and kgpi will also have a chance for a couple hours of 
vicinity showers. Winds will be gusty with any thunderstorm, and 
with the frontal passage.

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