| ***Permissive Burn Day ***
Winds will become northerly today as the recent trough moves into the Great Basin. These winds will not be too strong however. Expect good vertical mixing this afternoon as AM stability remains low. Overall...dispersion will be fair to good today with the only limiting factor being lighter winds.
*** Permissive Burn Day***
North winds will strengthen for Friday as the pressure gradient tightens between the trough and a ridge over the eastern Pacific. This ridge will build into the North State for the weekend, bringing lighter winds and warmer temps, especially on Sunday. The ridge should peak in strength early next week before weakening a bit beyond that. Overall...expect a deterioration in dispersion for next week with the ridge in place.
|Mixing Height Discussion:|
|Valley: Mixing heights will reach 2500-3000 feet by afternoon.
|Valley: North to northwesterly 5-10 mph.
Delta: Westerly 8-12 mph.
