Wednesday surface high pressure west of the Continental
Divide and over southwest MT continues to strengthen, spreading the stronger
inversions and lighter winds across most of north and west ID as well as north
and east MT with POOR to FAIR dispersion. Most of south ID and southwest MT will
continue to enjoy warm and dry temperatures supporting decent mixing heights
and afternoon breezes with FAIR to GOOD dispersion.
Thursday’s weather is similar to Wednesday, with high
pressure keeping winds light and dispersion POOR to FAIR in north and west ID
and north and east MT. However, the area of FAIR to GOOD dispersion expands in
south ID and southwest MT as the high starts to weaken.
Friday marks a significant change in dispersion around the
area, with no areas of POOR or even FAIR dispersion shown. North ID improves to
GOOD to VERY GOOD dispersion, and the rest of ID and MT has VERY GOOD to
EXCELLENT dispersion.
