TUESDDAY, September 02 Discussion

GOOD to EXCELLENT smoke dispersion conditions are expected  onTuesday as the NW flow weakens slightly and becomes more from the W. Morning valley and canyon temperature inversions will be slightly stronger but still should be able to break out by mid-monring. An isolated shower is possible along the northern fringes of Airshed #2 in the afternoon.. 

 

Extended outlook: 

GOOD to EXCELLENT smoke dispersion conditions are expected on Wednesday as an upper level low pressure area moves south from BC into WA. Transport wind flow will become from the WSW across ID and from the NE across most of MT. Scattered showers and storms are possible near the Canadian border in airsheds 1 and 11 in the afternoon. Elsewhere, expect dry and warm conditions.

 

GOOD to EXCELLENT smoke dispersion conditions are expected on Thursday as the trough of low pressure moves further SW to be over Central OR. Transport wind flow aloft will be from the SW while surface winds will be from the SW across ID. Across MT expect mostly NEsurface winds to continue. Isolated showers and thunderstorms will be possible across SW MT and Central ID in the afternoon.

WEDNESDAY, September 03 Discussion

GOOD to EXCELLENT smoke dispersion conditions are expected on Wednesday as an upper level low pressure area moves south from BC into WA. Transport wind flow will become from the WSW across the region while surface winds will be light and variable--diunrally driven. Scattered showers and storms are possible near the Canadian border in airsheds 1 and 11 in the afternoon. Elsewhere, expect dry and warm conditions.

 

Extended outlook: 

GOOD to EXCELLENT smoke dispersion conditions are expected on Thursday as the trough of low pressure moves further SW to be over Central OR. Transport wind flow aloft will be from the SW while surface winds will be from the SW across ID. Across MT expect mostly NE surface winds to continue. Isolated showers and thunderstorms will be possible across SW MT and Central ID in the afternoon.

 

GOOD to EXCELLENT smoke dispersion conditions are expected on Friday as the upper level trough slowly begins to move inland. Transport wind flow across ID will be generally from the NW while across MT it will be lighter and from the SW. Surface winds will be genrally from the NE.  Scattered showers and thunderstorms will be possible across SW and Central-Eastern MT.

 

GOOD to EXCELLENT smoke dispersion conditions will be possible across MT and ID on Saturday as an elongated and weak upper level trough remains over the region. The odd NE-SW orientation of the trough will continue to promote Easterly flow over both MT and ID. Scattered showres will be possible along and south of the I-90 corridor.
