...LOW DISPERSIONS EXPECTED AT THE SITE TODAY AND FRIDAY ...
.DISCUSSION...
Very low transport winds and stable conditions will encourage low
dispersions and fog in the morning hours at the burn site. Fog
should evaporate by 9 or 10am with daytime heating but expect low
dispersions to remain, despite 3 kft mixing heights. Light east
winds become southerly around 5 mph this afternoon. Min RHs bottom
out around 55%.
For tonight winds will go calm and fog is likely. Some areas could
see dense fog. For Friday, slightly higher winds from the south
are expected but with low mixing heights, dispersions will again
remain low. Min RHs will continue their climb upwards as low-level
moisture returns. RHs should bottom out around 60% on Friday.
