|***Permissive Burn Day ***
High pressure building within the large scale trough will provide pleasant, warming conditions to the region today. Stability has moved up a few notches and winds will remain light in response to this transition. This will subdue dispersion conditions a bit from this weekend. But all things being equal, conditions are still very good for August.
***Permissive Burn Day***
A more normal trough response pattern returns tomorrow as the delta breeze strengthens and winds take a more southerly, onshore direction though Wednesday. A transition period both Thursday and Friday as the trough finally moves out this weekend. Dispersion and air quality still look good through this period.
|Mixing Height Discussion:|
|Valley: Mixing heights above 2,000 feet by early afternoon
|Valley:Northerly this morning 3-8 mph, turning light and variable tending Southerly to 5 mph late.
