Meteorology/Dispersion Discussion  latest update: 05/03/2016 07:23

Tuesday 03 May Discussion:
GOOD to EXCELLENT smoke dispersion conditions are expected all areas 
Tuesday as light south flow ID and Western MT increases afternoon instability and mixes light SW winds down in the afternoon. Light SE-E transport flow Central/Eastern MT. 

GOOD to EXCELLENT smoke dispersion conditions are expected all areas across ID and MT on Wednesday as the upper level high pressure ridge shifts to Eastern MT. SW surface winds west of the Divide in afternoon and isolated showers/wet storms. Very warmy/dry Central/Eastern MT with S-SW transport flow. 

Extended Forecast:
GOOD to EXCELLENT smoke dispersion conditions are expected all areas across ID and MT on Thursday. Stronger south flow aloft west of the Divide will bring scattered showers/wet storms afternoon and SW-W surface winds. Very warm/dry Central/Eastern MT with isolated wet storms higher terrain and light SE-S transport flow. 

GOOD-EXCELLENT dispersion all areas expected Friday. Upper level low tracking into SW US will leave ID and MT under cool NE-E flow aloft. Scattered showers higher terrain southern MT. NE-E transport flow west of the Divide. Northerly transport flow Central/Eastern MT.
