TUESDAY, October 21 Discussion

GOOD to EXCELLENT smoke dispersion conditions are expected Tuesday across ID and MT as another cold front begins its approach from the West in the afternoon. Scattered showers will begin to move into ID by mid-day. and SW flow will begin to strenghten. Morning valley and canyon temperature inversions should be able to break out by late morning.

Extended outlook: 

GOOD smoke dispersion conditions are expected on Wednesday as a warm, weak SW flow patttern develops over the region. Temperatures will be well above normal. Valley and canyon temperature inversions should break by late morning thus allowing for good smoke dispersion in the afternoon. Valley/canyon temperature inversions will be quick to develop Wednesday evening as a ridge of  high pressure begins to develop over ID and W MT overnight.


MODERATE to GOOD smoke dispersion conditions are expected across W MT and ID on Thursday as a weak ridge of high pressure strenghtens over the area. While transport wind flow will remain light and from the SW...there is some concern that the morning temperature inversions in the some of the lower and/or more narrow valleys and canyons may not mix out for the afternoo burn period. Impact zones should be monitored. E MT will continue to see GOOD smoke dispersion conditions.
