| *** Permissive Burn Day ***
High pressure will continue to strengthen over the region today. This ridge has brought slightly stronger AM stability, although PM levels remain about the same as yesterday. Expect poor dispersion today as winds will remain on the light side until late afternoon, when flow through the Delta should increase a bit. Use plenty of caution if burning today.
*** Permissive Burn Day ***
A slight cooling trend is in store for Monday in the south Valley as onshore flow increases. Elsewhere, high temperatures will remain at or above the century mark. Expect poor dispersion through the work week as strong high pressure remains anchored over the region. The second half of the week looks to be the warmest and most stagnant. Some relief may be in sight for next weekend, but forecast models are unclear at this time.
