TUESDAY, March 11 Discussion
GOOD to EXCELLENT smoke dispersion conditions are expected to continue into Tuesday as a somewhat cold cold front drops SE through Southern ID and MT early in the day. This front should bring much cooler temperatures along with pockets of light snowfall amounts to the mountains of N ID and W MT. Transport wind flow will generally be from the NNW and light. The lifting associated with the passage for the front should be good enough to keep the atmosphere well-mixed.
Extended outlook:
Overall GOOD smoke dispersion conditions are expected Wednesday as a ridge of high pressure begins to move inland from the coast to be over ID by morning. While MODERATE smoke dispersion conditions are expected across ID and W MT during the morning hours...the atmosphere should be able to mix out by mid-day allowing for GOOD smoke dispersion in the afternoon. Transport wind flow will be light and from the NNW across W MT and ID and breezier across E MT.
GOOD to EXCELLENT smoke dispersion conditions will return Thursday as a fast moving cold front sweeps ESE across the region and mixes out all airsheds. Transport wind flow will be from the WNW during the day and will become breezy as the front passes through W MT in the morning, Central MT around mid-day, and E MT during the afternoon. It appears that this will be a dry front with little, if any precipiation expected.
Overall GOOD smoke dispersion conditions are expected on Friday as the ridge of high pressure begins to weaken in response to a system passing through it to the south. Morning temperature inversions should yield to overall GOOD smoke dispersion conditions by mid-day. The precip associated with the passing system should remain just south of the region...though S ID could get clipped.
