NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
223 PM MDT Wed Apr 16 2014 


..more snow over the mountain passes late Thursday night/Friday... 
..Gusty west winds Friday across western Montana/Lemhi County... 


Discussion... 
tonight...there is enough Pacific moisture caught up in a 
northwesterly flow aloft to keep clouds and scattered showers 
across much of northern Idaho and western Montana through the 
evening hours. Showers will be tapering off after nightfall with 
the exception of the northwest Montana Mountains. 


Thursday...a low amplitude ridge of high pressure will serve as 
some limited protection from the influx of moisture coming in off 
the Pacific Ocean. We still expect plenty of clouds, but any 
chances of precipitation will be confined to the Idaho Panhandle 
and northwest Montana. High temperatures in the valleys will range 
from the low 60s across north-central Idaho to mid 50s in 
northwest Montana. 




Thursday night...a vigorous frontal system will be passing through 
the northern rockies region overnight. This system possesses 
considerable moisture and strong dynamics. We will see snow levels 
lower quickly after midnight with accumulating snow impacting the 
mountain passes along the Idaho/Montana border, as well as Marias 
Pass. Road conditions may become difficult towards morning as 
temperatures cool and snow begins to stick to Road surfaces. 
Precipitation in the valleys should remain mostly as rain. Some of 
the heaviest rainfall will occur over the Idaho Panhandle and 
adjacent mountains on the Montana side. Heavier rainfall could 
result in some loose debris (rocks/soil) spilling onto roadways in 
those lower valleys in western Idaho County. 


Friday...strong westerly winds aloft combined with a supportive 
surface pressure gradient will promote windy conditions across 
western Montana and Lemhi County during the day. Choppy surface 
water conditions on area lakes will likely start up right away in 
the morning and continue throughout the day. However, winds are 
not expected to be very gusty across western Clearwater and Idaho 
counties in north-central Idaho. Mountain snow showers can be 
expected, but any additional snow will likely melt as it falls on 
the roadways by mid-morning for minimal impact. 


Friday night...both wind and shower activity will be diminishing 
quickly during the evening hours in response to higher pressure 
building in from the west. If there is enough clearing 
overnight, valley fog may become an issue with temperatures 
cooling well into the 20s at many locations. Lower valleys across 
Clearwater and Idaho counties will remain in the 30s to near 40 
degrees however. 


All markers point towards a very pleasant Easter weekend with 
Saturday likely a touch warmer than Sunday. However periods of 
sunshine will be limited both days with moisture still finding its 
way through the weak high pressure ridge. Some afternoon showers 
are possible late in the day across northwest and SW Montana on Sunday 
with shower activity becoming more widespread and stronger Monday 
and Tuesday afternoon. In fact the steepening southwesterly flow 
aloft will lend to a progressively better chance for thunderstorms 
each day. 


By Wednesday, the longer range models are showing a stronger 
weather system ejecting out of the Desert Southwest/Great Basin 
regions and into the northern rockies. A quick analysis of prior 
systems with similar trajectory and origin reveals the potential 
for a wide variety of impacts attributed to heavy precipitation. 
At this time, confidence is higher than normal that we'll see a 
strong weather system with abundant precipitation. However, there 
remains lower confidence in the thermal profile which will 
ultimately dictate if those impacts are related to excess rainfall 
(i.E. Flooding, mud/rock slides & debris flows), heavy snowfall 
(impacting travel over mountain passes, back country and higher 
elevation valleys) or a culmination of the two. Stay tuned as we 
sort out these details over the next few days. 




&& 


Aviation...variable mid to high level cloud cover will help keep 
winds at Bay today with only a few brief hours of breezy 
conditions possible this afternoon at kmso, kgpi and kbtm. But any 
wind will subside shortly after 17/0200z this evening. Otherwise 
expect similar cloudiness to persist throughout the night and into 
tomorrow in advance of a stronger weather system expected into the 
region tomorrow night through Friday. 


&& 


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