ARB Comments
Cautionary Comments:
*** Permissive Burn Day ***
Temperatures were a bit warmer this morning due to overnight mid-level clouds. AM stability is not as high as a result. Winds will be about the same as yesterday as a weak trough moves by to our north. Dispersion will be fair to good today after the morning clouds clear out.

24hr Outlook
*** Permissive Burn Day. ***
A trough will slowly deepen over the region this week, leading to more onshore flow and below-normal temps. Winds on Wednesday will be about the same as today,
