Discussion... 


The weather over the northern rockies this week will be dominated 
by a ridge of high pressure centered over western Montana and 
monsoonal moisture moving slowly around the ridge throughout the 
period. The high pressure under the ridge will bring continued hot 
temperatures, and the moisture support a chance of showers and 
thunderstorms at times throughout the week. With an absence of any 
significant upper-level features to aid in triggering storms, 
the main factor will be very weak and subtle impulses moving 
through the ridge, and thunderstorm chances will be largely 
dependent on moisture availability. Thus, while there is low 
confidence in any one day, it is likely that midweek will have the 
best chance of thunderstorm activity as models show the best 
moisture moving through in that period. 


In terms of impacts to western Montana and north-central Idaho, we 
are not expecting anything significant at this time as the storms 
do not look to be particularly strong. Lightning is still a 
concern, as with all thunderstorms, although increasing moisture 
during the week could help offset fire vulnerability. Flash 
flooding, while not outside the realm of possibility, is not a big 
concern at this time as storm motion looks to speed up by the time 
the best moisture arrives midweek. 


Looking ahead to the latter part of the week and into the 
weekend, there is a potential for a stronger upper-level disturbance, 
originally rooted in the subtropics, to drift northward and bring 
better instability as well as increased moisture to the northern 
rockies around Saturday. We will be watching this feature closely 
in the coming days. 


&& 


Aviation...a small threat exists for afternoon and evening 
thunderstorms, mainly impacting ksmn and perhaps kbtm. Meanwhile, 
breezy north winds are possible at kmso late this afternoons. 
Conditions will clear out shortly after sunset with winds 
diminishing.
