Meteorology/Dispersion Discussion  latest update: 03/24/2017 07:16

Progressive moist pattern with weak systems every day or two will continue until further notice, which is remarkable, as most western areas have not seen a more than one week dry spell since September! This means generally good dispersion overall through next week. The only day with any significant limitations will be Sunday, when weak ridging will produce only marginal dispersion conditions in North ID and Western MT valleys. Snow levels will generally stay above most valleys but passes will get light accumulations tonight/tomorrow and Monday. 
Friday 24 March Discussion:
GOOD smoke dispersion will occur ID and Western MT Today with south-southwest surface/transport flow. Rain ID and NW MT late. GOOD-EXCELLENT smoke dispersion Central/Eastern Montana with southeast-southwest surface/transport flow. 
GOOD-EXCELLENT smoke dispersion will occur ID and Western MT Saturday with southwest-west surface/transport flow. Scattered valley rain and mountain snow showers. GOOD-EXCELLENT smoke dispersion Central/Eastern Montana with west-northwest surface/transport flow. Scattered showers S-Central and SE MT. 
MODERATE-GOOD dispersion will occur North ID and Western MT Sunday with light and variable surface/transport flow under weak high pressure ridging. Light SOUTHERLY surface/transport flow southern ID with GOOD dispersion. GOOD-EXCELLENT dispersion will occur Central/Eastern MT with west-northwest surface/transport flow. 
GOOD smoke dispersion will occur North ID and Western MT Monday with light west-northwest surface/transport flow. Rain/Mountain snow ID and Western MT. GOOD-EXCELLENT smoke dispersion Central/Eastern Montana with southeast-southwest surface/transport flow. 
GOOD dispersion will occur North ID and Western MT Tuesday with southwest-west surface/transport flow. GOOD-EXCELLENT dispersion will occur Central/Eastern MT with west-northwest surface/transport flow. Scattered showers.
GOOD smoke dispersion will occur North ID and Western MT Wednesday with south-southwest surface/transport flow. Rain/Mountain snow ID and Western MT. GOOD-EXCELLENT smoke dispersion Central/Eastern Montana with westerly surface/transport flow.
